-自定义或第三方的表单控件，也可以与 Form 组件一起使用。只要该组件遵循以下的约定：
-
-> - 提供受控属性 `value` 或其它与 [`valuePropName`](http://ant.design/components/form/#getFieldDecorator-参数) 的值同名的属性。
-> - 提供 `onChange` 事件或 [`trigger`](http://ant.design/components/form/#getFieldDecorator-参数) 的值同名的事件。
-> - 支持 ref：
->   - React@16.3.0 之前只有 Class 组件支持。
->   - React@16.3.0 及之后可以通过 [forwardRef](https://reactjs.org/docs/forwarding-refs.html) 添加 ref 支持。（[示例](https://codesandbox.io/s/7wj199900x)）
-
-## en-US
-
-Customized or third-party form controls can be used in Form, too. Controls must follow these conventions:
-
-> - It has a controlled property `value` or other name which is equal to the value of [`valuePropName`](http://ant.design/components/form/?locale=en-US#getFieldDecorator's-parameters).
-> - It has event `onChange` or an event which name is equal to the value of [`trigger`](http://ant.design/components/form/?locale=en-US#getFieldDecorator's-parameters).
-> - Support ref:
->   - Can only use class component before React@16.3.0.
->   - Can use [forwardRef](https://reactjs.org/docs/forwarding-refs.html) to add ref support after React@16.3.0. ([Sample](https://codesandbox.io/s/7wj199900x))

-  zh-CN: 表单数据存储于上层组件

----
-
-## zh-CN
-
-通过使用 `onFieldsChange` 与 `mapPropsToFields`，可以把表单的数据存储到上层组件或者 [Redux](https://github.com/reactjs/redux)、[dva](https://github.com/dvajs/dva) 中，更多可参考 [rc-form 示例](http://react-component.github.io/form/examples/redux.html)。
-
-**注意：**`mapPropsToFields` 里面返回的表单域数据必须使用 `Form.createFormField` 包装。
-
-## en-US
-
-We can store form data into upper component or [Redux](https://github.com/reactjs/redux) or [dva](https://github.com/dvajs/dva) by using `onFieldsChange` and `mapPropsToFields`, see more at this [rc-form demo](http://react-component.github.io/form/examples/redux.html).
-
-**Note:** You must wrap field data with `Form.createFormField` in `mapPropsToFields`.
-
-**Note:** Here, errors are passed to higher order component in `onFieldsChange` and passed back in `mapPropsToFields`.
-
-```jsx
-import { Form, Input } from 'antd';

-# 表单实现原理
-
----
-
-antd 中的 [Form](https://github.com/ant-design/ant-design/blob/master/components/form/index.zh-CN.md) 组件基于 [rc-form](https://github.com/react-component/form) 实现。本文第一部分将介绍 rc-form 库；第二部分再介绍 antd 中的 Form 组件；第三部分将结合表单组件的使用，回顾前两部分的内容。
-
----
-
-### rc-form
-
-常规收集表单数据并作校验，只需以 store 实时记录表单数据，校验后重绘表单。这样的思路以业务代码为例，就是，以数据模型 model 集成数据处理操作，再通过 setState 将 model 中的实时数据注入组件中，并驱动组件重绘（除了 setState 方法以外，也可以使用 forceUpdate 方法重绘组件，并在 render 阶段重新访问 model 中的实时数据）。
-
-#### FieldsStore
-
-在 rc-form 中，上述数据模型的具体实现为 FieldsStore 类。如前所述，FieldsStore 实例与视图层的交互逻辑为，在用户行为驱动字段变更时，即时存储字段的值及校验信息（本文以校验信息代指校验文案和校验状态），继而调用表单组件实例的 forceUpdate 方法强制重绘；在绘制过程中，再从 FieldsStore 实例读取实时数据和校验信息。
-
-建模方面，FieldsStore 实例以 fields 属性存储表单的实时数据，即由用户行为或开发者显式更新的数据。本文把实时数据已存入 fields 中的字段称为已收集字段；反之，称为未收集字段。以下是 fields\[name\] 中成员属性的意义（name 为字段名，下同）。
-
-- value 字段的值。
-- errors 校验文案，数组形式。
-- validating 校验状态。
-- dirty 脏值标识。真值时意味着字段的值已作变更，但未作校验。
-- touched 用户行为标识。通常情况下，真值时意味着用户行为已促使字段的值发生了变更。
-
-FieldsStore 实例又以 fieldsMeta 属性存储字段的元数据。元数据作为配置项，通常是指定后不再变更的数据，用于操控表单数据转换等行为。元数据通过下文中 getFieldProps, getFieldDecorator 方法的次参 fieldOption 配置。以下是 fieldsMeta\[name\] 中部分成员属性的意义（如不作特殊说明，该成员属性即 fieldOption 中的同名属性）。
-
-- validate 校验规则和触发事件，用于约定在何种事件下以何种方式校验字段的值，\[{ rules, trigger }\] 形式。通过 fieldOption.validate, fieldOption.rules, fieldOption.validateTrigger 配置。
-- hidden 设置为 true 时，validateFields 将不会校验该字段，需要开发者手动校验，并且，getFieldsValue, getFieldsError 等方法也将无法获取该字段的数据及校验信息等实时数据。适用场景如勾选协议复选框，当其已勾选时，提交按钮才可点击，该复选框的值不会出现在全量表单数据中。本文假定配置了 hidden 为 true 的字段为虚拟隐藏项。
-- getValueFromEvent(event) 用于从 event 对象中获取字段的值，适用场景如处理 input, radio 等原生组件。特别的，当字段组件输出的首参不是 event 对象时，getValueFromEvent 将对首参进行数据转化，以满足特定的场景，比如由开发者指定具体首参内容的自定义字段组件。
-- initialValue 字段的初始值。当字段的值未作收集时，初始值用于作为字段的值。
-- valuePropName 约定字段的值以何种 props 属性注入字段组件中，适用场景如将字段的值以 props.checked 属性注入 radio 组件中。注入字段组件的值数据 props 由 getFieldValuePropValue 方法生成，下同。
-- getValueProps(value) 用于转化字段的值，输出 props 以注入字段组件中。适用场景如当 get, post 请求的数据结构不同时，且字段组件以 post 请求的数据结构输出字段的值、以 get 请求的数据结构接受字段的值，那就可以使用 getValueProps 将 post 请求的数据结构转换为 get 请求的数据结构。
-- normalize(newValue, oldValue, values) 用于转化存入 FieldsStore 实例的字段的值。使用案例如[全选按钮](https://codepen.io/afc163/pen/JJVXzG?editors=001)。
-
-在此基础上，FieldsStore 提供了一些便捷的访问器操作。需要说明的是，rc-form 借助 [lodash](https://github.com/lodash/lodash)，支持以嵌套结构定义字段名，即使用 '.', '\[|\]' 作为分割符，如 'a.b' 意味着 a 对象下的 b 属性；'c\[0\]' 意味着 c 数组的首项。本文约定匹配字段指，所有以指定字符串起始或等值的字段列表。为此，FieldsStore 提供 isValidNestedFieldName 用于校验字段名不能作为表单中另一个字段名的成员；flattenRegisteredFields 用于传参数据作扁平化处理；getValidFieldsFullName 用于获取匹配字段列表，但不包含虚拟隐藏项。除此以外，FieldsStore 提供了对实时数据和元数据的读取操作，特别的，部分 api 可用于获取匹配字段的实时数据，参见[文档](https://ant.design/components/form-cn/)。
-
-#### BaseForm
-
-与业务 model 不同的是，FieldsStore 仅作为表单实时数据和元数据的存储器，校验数据等方法由 BaseForm 提供。BaseForm 既作为 HOC 容器，能为开发者自定义表单组件（下文用自定义表单替代）注入表单操作函数集，通常是 props.form；又用于装饰字段组件或其 props，以收集字段的元数据、通过绑定函数收集或校验字段的实时数据。因此，可以部分认为，BaseForm 即 FieldsStore 和视图层桥接的控制器。其机制为：
-
-首先，通过 createBaseForm(option, mixins) 创建装饰函数。装饰函数可以为自定义表单包裹上 BaseForm 容器。参数 option 用于配置表单层面的绑定函数、校验文案以及部分字段组件的 props 属性名；mixins 将作为实例方法混入 BaseForm，特别的，createDOMForm 函数即通过这一机制混入了 validateFieldsAndScroll 方法。
-
-其次，在 BaseForm 的 getInitialState 阶段，将创建 FieldsStore 实例，并初始化 clearedFieldMetaCache 等缓存。这些缓存的意义包含缓存字段组件实例，缓存内置的 ref 引用及绑定函数，缓存渲染状态等。特别的，clearedFieldMetaCache 用于在 ref 引用函数执行时缓存字段的实时数据和元数据，以便于在字段重绘过程中的第两次执行 ref 引用时，恢复 FieldsStore 存储的实时数据和元数据（参见[源码](https://github.com/react-component/form/blob/master/src/createBaseForm.js)中的 saveRef 方法）。不然，元数据的丢失将导致数据校验无法正常工作。
-
-其次，执行 render 方法，将表单操作函数集通过 props 注入自定义表单。介于此，在自定义表单中，开发者可以获取到表单的实时数据，或者更新表单数据，或者校验表单，以完成特定的处理逻辑。
-
-其次，由 BaseForm 提供的 getFieldProps 或 getFieldDecorator 实例方法完成字段组件的渲染。以下是 getFieldProps, getFieldDecorator 的意义。
-
-- getFieldProps(name, fieldOption) 用于为 FieldsStore 实例收集字段的元数据，如经转化后的校验规则等；指定字段组件的 ref 引用函数；为字段组件绑定 onCollect, onCollectValidate 实例方法，以在指定事件触发时收集或校验字段的值；最终将输出注入字段组件的 props，包含全量的元数据和实时数据、以及字段的值。
-- getFieldDecorator(name, fieldOption) 基于 getFieldProps 方法，直接装饰字段组件，这样就可以操控添加在字段组件上的 ref 引用函数及 props.onChange 等绑定函数。
-
-其次，当用户行为促使字段的值发生变更时，将执行 BaseForm 实例的 onCollect, onCollectValidate 方法，以收集或校验该字段的实时数据，并重绘表单。其中，rc-form 中的数据校验通过 [async-validate](https://github.com/yiminghe/async-validator) 库实现，具体实现为 BaseForm 实例的 validateFieldsInternal 方法。校验字段时，默认将沿用上一次的校验信息；当设置 force 为 true 时，将强制重新校验。
-
-详细的工作流程参见下方的时序图： <img class="preview-img no-padding" src="http://xzfyu.com/2018/11/04/ant%20design/antd-Form%20%E7%BB%84%E4%BB%B6/rc-form%E6%97%B6%E5%BA%8F%E5%9B%BE.png">
-
-### Form 表单
-
-#### 表单
-
-Form 组件本身并不承载逻辑，而是通过 props.className, props.prefixCls, props.layout, props.hideRequiredMark, props.onSubmit 设定注入 form 原生节点的样式类及绑定函数，以影响表单内部节点渲染时的样式。同时，Form 组件将为子组件传入 context.vertical 以区分是水平布局，还是垂直布局。
-
-#### 表单域
-
-FormItem 组件用于设定表单项的布局。如同受控组件和非受控组件，FormItem 组件提供两种使用方式：其一，当未设定校验信息相关的 props 属性时，FormItem 组件将自动根据内部字段组件实例的状况渲染校验文案及校验状态；其二，当设定校验信息相关的 props 属性时，FormItem 组件将根据开发者传入的 props 渲染校验文案及校验状态。在第一种使用方式下，FormItem 组件只可以包含一个字段组件；在第二种使用方式下，FormItem 组件中可以包含多个字段组件，布局也更为灵活。这里说的相关 props 属性包含：校验文案 help, 校验状态 validateStatus（用于绘制反馈图标）, 必填标识 required, 字段名 id（影响点击 label 时聚焦哪个字段元素）。
-
-那么，FormItem 又是怎样自动收集字段组件的校验数据呢？因为在 BaseForm 组件提供的 getFieldProp 方法，字段名、元数据和实时数据都将作为特殊的 props 属性传入到字段组件中，所以作为字段组件容器的 FormItem，就可以通过这些特殊的 props 属性判断子组件实例是不是一个字段组件实例。当其为字段组件实例时，进一步收集实时的校验信息，从校验规则中获取是否必填标识，以完成表单域的渲染。
-
-此外，FormItem 可以使用 props.labelCol, props.wrapperCol 属性栅格化布局标签组件和字段组件，其实现借助于 antd 提供的 [Row, Col 组件](https://ant.design/components/grid-cn/)。当点击标签 label 时，FormItem 提供的绑定函数也能自动为字段组件获得焦点。这里不再多加介绍。
-
-### 使用与回顾
-
-#### 创建 HOC 容器
-
-结合上文，antd 使用 Form.create(options)(CustomizedForm) 形式为用户自定义表单包裹上 BaseForm 高阶组件，以此植入 props.form 表单操作函数集。
-
-高阶组件影响对自定义表单设置 ref 引用。默认可使用 BaseForm 实例的 refs.wrappedComponent 属性访问 CustomizedForm 实例，其次也可以通过 props.wrappedComponentRef 为 CustomizedForm 实例配置 ref 引用（参考案例 —— 弹出层中的新建表单）。当自定义表单可切换或者需要对外交互时，设置 ref 引用通常是不可避免的。
-
-高阶组件影响 props 传递。antd 既支持使用 options.mapPropsToFields 将 BaseForm 实例获得的 props 转化成表单的实时数据（需要结合 Form.createFormField 方法），又支持在 CustomizedForm 实例中调用 props.form.setFields 方法更新实时数据。当 options.mapPropsToFields, options.onFieldsChange 方法结合使用时，可用于完成自定义表单和上层组件、或者 view 层和 store 层的交互（参考案例 —— 表单数据存储于上层组件）。
-
-一般认为，对整张表单的控制，需要借助于 Form.create 方法的首参 options 配置实现。
-
-#### 操作函数集
-
-通常情况下，CustomizedForm 实例可通过 props.form 获取到表单操作函数集。当然，开发者也可以通过 options.formPropName 指定操作函数集的 props 属性名。
-
-操作函数集包含 getFieldProps, getFieldDecorator, getFieldInstance, setFields, setFieldsValue, setFieldsInitialValue, resetFields, validateFields, getFieldsValue, getFieldValue, getFieldsError, getFieldError, isFieldsValidating, isFieldValidating, isFieldsTouched, isFieldTouched 方法，即用于装饰字段组件（或其 props）、获取字段组件实例、设置或获取实时数据、重置或校验字段。
-
-如上文所说，getFieldProps, getFieldDecorator 方法即用于自动为字段组件绑定监听函数，这样就可以在指定事件触发时，收集和校验字段的值。同时，可以通过这两个方法将视图中未加显示的字段存入 FieldsStore 中（这时，可以将 FieldsStore 视为一个内置于表单组件的状态管理器）。比如在包含其他选项的单选框场景中，就可以使用 getFieldDecorator 创建虚拟字段，通过绑定函数将单选框和输入框的值赋值到该虚拟字段中，并使用该虚拟字段的校验信息绘制 FormItem。参考案例 —— 动态增减表单项。
-
-上述单选框场景，也可以使用自定义字段组件 CustomizedField 实现。参考案例 —— 自定义字段组件。当使用自定义字段组件时，通过 getFieldInstance 获取 CustomizedField 的实例可能是必不可少的，这样可以把略显复杂的数据校验方法集成在 CustomizedField 中。此外，在字段组件中，既可以通过 props.value 属性获得字段的值，也可以通过 props\['data-**meta'\], props\['data-**field'\] 获得字段的全量元数据和实时数据。
-
-在 CustomizedForm 中，使用 getFieldValue 可以取得字段的实时更新值，这样就能根据指定字段的值控制另一个字段的显隐。此外，通过在字段组件的 onChange 绑定函数中调用 setFieldValue，也能对另一个字段组件加以赋值，这样就可以实现表单的联动效果，参考案例 —— 表单联动。若在字段组件的 onChange 绑定函数中调用 validateFields 方法，就可以实现关联字段的校验，比如表单中存在设置最大最小值的两个输入框，参考案例 —— 动态校验规则。
-
-使用 getFieldError, isFieldValidating 获取到的校验信息可用于直接绘制 FormItem，这样就能更加细微地操控 FormItem 下字段组件的布局，比如放置多个字段组件。当然，对于多个字段组件公用校验信息的场景，也可以使用包含多个字段的 CustomizedField 实现。isFieldTouched 可判断用户是否对字段组件有触发数据收集和校验的行为，参考案例 —— 水平登录栏。介于 BaseForm 默认在 onChange 事件中收集并校验字段的值，在这种情形下，也可以通过 isFieldTouched 判断字段的值是否已作更新，而不需要在 CustomizedForm 中设置特殊的更新标识。
-
-#### 其他
-
-当不使用 Form.create 为字段组件自动绑定校验方法时，可以使用 Form, FormItem 组件设定表单的布局、校验信息的绘制，参考案例 —— 表单布局、自行处理表单数据、自定义校验。

-- `horizontal`：to horizontally align the `label`s and controls of the fields. (Default)
-- `vertical`：to vertically align the `label`s and controls of the fields.
-- `inline`：to render form fields in one line.
-
-## Form Item Component
-
-A form consists of one or more form fields whose type includes input, textarea, checkbox, radio, select, tag, and more. A form field is defined using `<Form.Item />`.
-
-```jsx
-<Form.Item {...props}>{children}</Form.Item>
-```
-
-## API
-
-### Form
-
-**more example [rc-form](http://react-component.github.io/form/)**。
-
-| Property | Description | Type | Default Value |
-| --- | --- | --- | --- |
-| form | Decorated by `Form.create()` will be automatically set `this.props.form` property | object | n/a |
-| hideRequiredMark | Hide required mark of all form items | Boolean | false |
-| labelAlign | Label text align | 'left' \| 'right' | 'right' |
-| labelCol | (Added in 3.14.0. Previous version can only set on FormItem.) The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>` | [object](https://ant.design/components/grid/#Col) |  |
-| layout | Define form layout | 'horizontal'\|'vertical'\|'inline' | 'horizontal' |
-| onSubmit | Defines a function will be called if form data validation is successful. | Function(e:Event) |  |
-| wrapperCol | (Added in 3.14.0. Previous version can only set on FormItem.) The layout for input controls, same as `labelCol` | [object](https://ant.design/components/grid/#Col) |  |
-| colon | change default props colon value of Form.Item | boolean | true |
-
-### Form.create(options)
-
-How to use：
-
-```jsx
-class CustomizedForm extends React.Component {}
-
-CustomizedForm = Form.create({})(CustomizedForm);
-```
-
-The following `options` are available:
-
-| Property | Description | Type |
-| --- | --- | --- |
-| mapPropsToFields | Convert props to field value(e.g. reading the values from Redux store). And you must mark returned fields with [`Form.createFormField`](#Form.createFormField). Please note that the form fields will become controlled components. Properties like errors will not be automatically mapped and need to be manually passed in. | (props) => ({ \[fieldName\]: FormField { value } }) |
-| name | Set the id prefix of fields under form | - |
-| validateMessages | Default validate message. And its format is similar with [newMessages](https://github.com/yiminghe/async-validator/blob/master/src/messages.js)'s returned value | Object { \[nested.path]: String } |
-| onFieldsChange | Specify a function that will be called when the fields (including errors) of a `Form.Item` gets changed. Usage example: saving the field's value to Redux store. | Function(props, changedFields, allFields) |
-| onValuesChange | A handler while value of any field is changed | (props, changedValues, allValues) => void |
-
-If you want to get `ref` after `Form.create`, you can use `wrappedComponentRef` provided by `rc-form`, [details can be viewed here](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140).
-
-```jsx
-class CustomizedForm extends React.Component { ... }
-
-// use wrappedComponentRef
-const EnhancedForm =  Form.create()(CustomizedForm);
-<EnhancedForm wrappedComponentRef={(form) => this.form = form} />
-this.form // => The instance of CustomizedForm
-```
-
-If the form has been decorated by `Form.create` then it has `this.props.form` property. `this.props.form` provides some APIs as follows:
-
-> Note: Before using `getFieldsValue` `getFieldValue` `setFieldsValue` and so on, please make sure that corresponding field had been registered with `getFieldDecorator`.
-
-| Method | Description | Type |
-| --- | --- | --- |
-| getFieldDecorator | Two-way binding for form, please read below for details. |  |
-| getFieldError | Get the error of a field. | Function(name) |
-| getFieldsError | Get the specified fields' error. If you don't specify a parameter, you will get all fields' error. | Function(\[names: string\[]]) |
-| getFieldsValue | Get the specified fields' values. If you don't specify a parameter, you will get all fields' values. | Function(\[fieldNames: string\[]]) |
-| getFieldValue | Get the value of a field. | Function(fieldName: string) |
-| isFieldsTouched | Check whether any of fields is touched by `getFieldDecorator`'s `options.trigger` event | (names?: string\[]) => boolean |
-| isFieldTouched | Check whether a field is touched by `getFieldDecorator`'s `options.trigger` event | (name: string) => boolean |
-| isFieldValidating | Check if the specified field is being validated. | Function(name) |
-| resetFields | Reset the specified fields' value(to `initialValue`) and status. If you don't specify a parameter, all the fields will be reset. | Function(\[names: string\[]]) |
-| setFields | Set value and error state of fields. [Code Sample](https://github.com/react-component/form/blob/3b9959b57ab30b41d8890ff30c79a7e7c383cad3/examples/server-validate.js#L74-L79) | ({<br />&nbsp;&nbsp;\[fieldName\]: {value: any, errors: \[Error\] }<br />}) => void |
-| setFieldsValue | Set the value of a field. (Note: please don't use it in `componentWillReceiveProps`, otherwise, it will cause an endless loop, [reason](https://github.com/ant-design/ant-design/issues/2985)) | ({ \[fieldName\]&#x3A; value }) => void |
-| validateFields | Validate the specified fields and get theirs values and errors. If you don't specify the parameter of fieldNames, you will validate all fields. | (<br />&nbsp;&nbsp;\[fieldNames: string\[]],<br />&nbsp;&nbsp;\[options: object\],<br />&nbsp;&nbsp;callback(errors, values)<br />) => void |
-| validateFieldsAndScroll | This function is similar to `validateFields`, but after validation, if the target field is not in visible area of form, form will be automatically scrolled to the target field area. | same as `validateFields` |
-
-### validateFields/validateFieldsAndScroll
-
-```jsx
-const {
-  form: { validateFields },
-} = this.props;
-validateFields((errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], (errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], options, (errors, values) => {
-  // ...
-});
-```
-
-| Method | Description | Type | Default |
-| --- | --- | --- | --- |
-| options.first | If `true`, every field will stop validation at first failed rule | boolean | false |
-| options.firstFields | Those fields will stop validation at first failed rule | String\[] | \[] |
-| options.force | Should validate validated field again when `validateTrigger` is been triggered again | boolean | false |
-| options.scroll | Config scroll behavior of `validateFieldsAndScroll`, more: [dom-scroll-into-view's config](https://github.com/yiminghe/dom-scroll-into-view#function-parameter) | Object | {} |
-
-#### Callback arguments example of validateFields
-
-- `errors`:
-
-  ```js
-  {
-    "username": {
-      "errors": [
-        {
-          "message": "Please input your username!",
-          "field": "username"
-        }
-      ]
-    },
-    "password": {
-      "errors": [
-        {
-          "message": "Please input your Password!",
-          "field": "password"
-        }
-      ]
-    }
-  }
-  ```
-
-- `values`:
-
-  ```js
-  {
-    "username": "username",
-    "password": "password",
-  }
-  ```
-
-### Form.createFormField
-
-To mark the returned fields data in `mapPropsToFields`, [demo](#components-form-demo-global-state).
-
-### this.props.form.getFieldDecorator(id, options)
-
-After wrapped by `getFieldDecorator`, `value`(or other property defined by `valuePropName`) `onChange`(or other property defined by `trigger`) props will be added to form controls, the flow of form data will be handled by Form which will cause:
-
-1. You shouldn't use `onChange` to collect data, but you still can listen to `onChange`(and so on) events.
-2. You cannot set value of form control via `value` `defaultValue` prop, and you should set default value with `initialValue` in `getFieldDecorator` instead.
-3. You shouldn't call `setState` manually, please use `this.props.form.setFieldsValue` to change value programmatically.
-
-#### Special attention
-
-If you use `react@<15.3.0`, then, you can't use `getFieldDecorator` in stateless component: <https://github.com/facebook/react/pull/6534>

----
-
-具有数据收集、校验和提交功能的表单，包含复选框、单选框、输入框、下拉选择框等元素。
-
-## 何时使用
-
-- 用于创建一个实体或收集信息。
-- 需要对输入的数据类型进行校验时。
-
-## 表单
-
-我们为 `form` 提供了以下三种排列方式：
-
-- 水平排列：标签和表单控件水平排列；（默认）
-- 垂直排列：标签和表单控件上下垂直排列；
-- 行内排列：表单项水平行内排列。
-
-## 表单域
-
-表单一定会包含表单域，表单域可以是输入控件，标准表单域，标签，下拉菜单，文本域等。
-
-这里我们封装了表单域 `<Form.Item />` 。
-
-```jsx
-<Form.Item {...props}>{children}</Form.Item>
-```
-
-## API
-
-### Form
-
-**更多示例参考 [rc-form](http://react-component.github.io/form/)**。
-
-| 参数 | 说明 | 类型 | 默认值 |
-| --- | --- | --- | --- |
-| form | 经 `Form.create()` 包装过的组件会自带 `this.props.form` 属性 | object | - |
-| hideRequiredMark | 隐藏所有表单项的必选标记 | Boolean | false |
-| labelAlign | label 标签的文本对齐方式 | 'left' \| 'right' | 'right' |
-| labelCol | （3.14.0 新增，之前的版本只能设置到 FormItem 上。）label 标签布局，同 `<Col>` 组件，设置 `span` `offset` 值，如 `{span: 3, offset: 12}` 或 `sm: {span: 3, offset: 12}` | [object](https://ant.design/components/grid/#Col) |  |
-| layout | 表单布局 | 'horizontal'\|'vertical'\|'inline' | 'horizontal' |
-| onSubmit | 数据验证成功后回调事件 | Function(e:Event) |  |
-| wrapperCol | （3.14.0 新增，之前的版本只能设置到 FormItem 上。）需要为输入控件设置布局样式时，使用该属性，用法同 labelCol | [object](https://ant.design/components/grid/#Col) |  |
-| colon | 配置 Form.Item 的 colon 的默认值 | boolean | true |
-
-### Form.create(options)
-
-使用方式如下：
-
-```jsx
-class CustomizedForm extends React.Component {}
-
-CustomizedForm = Form.create({})(CustomizedForm);
-```
-
-`options` 的配置项如下。
-
-| 参数 | 说明 | 类型 |
-| --- | --- | --- |
-| mapPropsToFields | 把父组件的属性映射到表单项上（如：把 Redux store 中的值读出），需要对返回值中的表单域数据用 [`Form.createFormField`](#Form.createFormField) 标记，注意表单项将变成受控组件, error 等也需要一并手动传入 | (props) => ({ \[fieldName\]: FormField { value } }) |
-| name | 设置表单域内字段 id 的前缀 | - |
-| validateMessages | 默认校验信息，可用于把默认错误信息改为中文等，格式与 [newMessages](https://github.com/yiminghe/async-validator/blob/master/src/messages.js) 返回值一致 | Object { \[nested.path]: String } |
-| onFieldsChange | 当 `Form.Item` 子节点的值（包括 error）发生改变时触发，可以把对应的值转存到 Redux store | Function(props, changedFields, allFields) |
-| onValuesChange | 任一表单域的值发生改变时的回调 | (props, changedValues, allValues) => void |
-
-经过 `Form.create` 之后如果要拿到 `ref`，可以使用 `rc-form` 提供的 `wrappedComponentRef`，[详细内容可以查看这里](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140)。
-
-```jsx
-class CustomizedForm extends React.Component { ... }
-
-// use wrappedComponentRef
-const EnhancedForm =  Form.create()(CustomizedForm);
-<EnhancedForm wrappedComponentRef={(form) => this.form = form} />
-this.form // => The instance of CustomizedForm
-```
-
-经过 `Form.create` 包装的组件将会自带 `this.props.form` 属性，`this.props.form` 提供的 API 如下：
-
-> 注意：使用 `getFieldsValue` `getFieldValue` `setFieldsValue` 等时，应确保对应的 field 已经用 `getFieldDecorator` 注册过了。
-
-| 方法       | 说明                                     | 类型       |
-| --- | --- | --- |
-| getFieldDecorator | 用于和表单进行双向绑定，详见下方描述 |  |

-| isFieldValidating | 判断一个输入控件是否在校验状态 | Function(name) |
-| resetFields | 重置一组输入控件的值（为 `initialValue`）与状态，如不传入参数，则重置所有组件 | Function(\[names: string\[]]) |
-| setFields | 设置一组输入控件的值与错误状态：[代码](https://github.com/react-component/form/blob/3b9959b57ab30b41d8890ff30c79a7e7c383cad3/examples/server-validate.js#L74-L79) | ({<br />&nbsp;&nbsp;\[fieldName\]: {value: any, errors: \[Error\] }<br />}) => void |
-| setFieldsValue | 设置一组输入控件的值（注意：不要在 `componentWillReceiveProps` 内使用，否则会导致死循环，[原因](https://github.com/ant-design/ant-design/issues/2985)） | ({ \[fieldName\]&#x3A; value }) => void |
-| validateFields | 校验并获取一组输入域的值与 Error，若 fieldNames 参数为空，则校验全部组件 | (<br />&nbsp;&nbsp;\[fieldNames: string\[]],<br />&nbsp;&nbsp;\[options: object\],<br />&nbsp;&nbsp;callback(errors, values)<br />) => void |
-| validateFieldsAndScroll | 与 `validateFields` 相似，但校验完后，如果校验不通过的菜单域不在可见范围内，则自动滚动进可见范围 | 参考 `validateFields` |
-
-### validateFields/validateFieldsAndScroll
-
-```jsx
-const {
-  form: { validateFields },
-} = this.props;
-validateFields((errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], (errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], options, (errors, values) => {
-  // ...
-});
-```
-
-| 参数 | 说明 | 类型 | 默认值 |
-| --- | --- | --- | --- |
-| options.first | 若为 true，则每一表单域的都会在碰到第一个失败了的校验规则后停止校验 | boolean | false |
-| options.firstFields | 指定表单域会在碰到第一个失败了的校验规则后停止校验 | String\[] | \[] |
-| options.force | 对已经校验过的表单域，在 validateTrigger 再次被触发时是否再次校验 | boolean | false |
-| options.scroll | 定义 validateFieldsAndScroll 的滚动行为，详细配置见 [dom-scroll-into-view config](https://github.com/yiminghe/dom-scroll-into-view#function-parameter) | Object | {} |
-
-#### validateFields 的 callback 参数示例
-
-- `errors`:
-
-  ```js
-  {
-    "username": {
-      "errors": [
-        {
-          "message": "Please input your username!",
-          "field": "username"
-        }
-      ]
-    },
-    "password": {
-      "errors": [
-        {
-          "message": "Please input your Password!",
-          "field": "password"
-        }
-      ]
-    }
-  }
-  ```
-
-- `values`:
-
-  ```js
-  {
-    "username": "username",
-    "password": "password",
-  }
-  ```
-
-### Form.createFormField
-
-用于标记 `mapPropsToFields` 返回的表单域数据，[例子](#components-form-demo-global-state)。
-
-### this.props.form.getFieldDecorator(id, options)
-
-经过 `getFieldDecorator` 包装的控件，表单控件会自动添加 `value`（或 `valuePropName` 指定的其他属性） `onChange`（或 `trigger` 指定的其他属性），数据同步将被 Form 接管，这会导致以下结果：
-
-1. 你**不再需要也不应该**用 `onChange` 来做同步，但还是可以继续监听 `onChange` 等事件。
-2. 你不能用控件的 `value` `defaultValue` 等属性来设置表单域的值，默认值可以用 `getFieldDecorator` 里的 `initialValue`。
-3. 你不应该用 `setState`，可以使用 `this.props.form.setFieldsValue` 来动态改变表单值。
-
-#### 特别注意
-
-如果使用的是 `react@<15.3.0`，则 `getFieldDecorator` 调用不能位于纯函数组件中: <https://github.com/facebook/react/pull/6534>
-
-#### getFieldDecorator(id, options) 参数
-
-| 参数 | 说明 | 类型 | 默认值 |
-| --- | --- | --- | --- |
-| id | 必填输入控件唯一标志。支持嵌套式的[写法](https://github.com/react-component/form/pull/48)。 | string |  |
-| options.getValueFromEvent | 可以把 onChange 的参数（如 event）转化为控件的值 | function(..args) | [reference](https://github.com/react-component/form#option-object) |
-| options.initialValue | 子节点的初始值，类型、可选值均由子节点决定(注意：由于内部校验时使用 `===` 判断是否变化，建议使用变量缓存所需设置的值而非直接使用字面量)) |  |  |
-| options.normalize | 转换默认的 value 给控件，[一个选择全部的例子](https://codepen.io/afc163/pen/JJVXzG?editors=001) | function(value, prevValue, allValues): any | - |
-| options.preserve | 即便字段不再使用，也保留该字段的值 | boolean | - |
-| options.rules | 校验规则，参考下方文档 | object\[] |  |
-| options.trigger | 收集子节点的值的时机 | string | 'onChange' |
-| options.validateFirst | 当某一规则校验不通过时，是否停止剩下的规则的校验 | boolean | false |
-| options.validateTrigger | 校验子节点值的时机 | string\|string\[] | 'onChange' |
-| options.valuePropName | 子节点的值的属性，如 Switch 的是 'checked' | string | 'value' |
-
-更多参数请查看 [rc-form option](https://github.com/react-component/form#option-object)。
-
-### Form.Item
-
-注意：一个 Form.Item 建议只放一个被 getFieldDecorator 装饰过的 child，当有多个被装饰过的 child 时，`help` `required` `validateStatus` 无法自动生成。
-
-| 参数 | 说明 | 类型 | 默认值 | 版本 |
-| --- | --- | --- | --- | --- |
-| colon | 配合 label 属性使用，表示是否显示 label 后面的冒号 | boolean | true |  |
-| extra | 额外的提示信息，和 help 类似，当需要错误信息和提示文案同时出现时，可以使用这个。 | string\|ReactNode |  |  |
-| hasFeedback | 配合 validateStatus 属性使用，展示校验状态图标，建议只配合 Input 组件使用 | boolean | false |  |
-| help | 提示信息，如不设置，则会根据校验规则自动生成 | string\|ReactNode |  |  |
-| htmlFor | 设置子元素 label `htmlFor` 属性 | string |  | 3.17.0 |
-| label | label 标签的文本 | string\|ReactNode |  |  |
-| labelCol | label 标签布局，同 `<Col>` 组件，设置 `span` `offset` 值，如 `{span: 3, offset: 12}` 或 `sm: {span: 3, offset: 12}`。在 3.14.0 之后，你可以通过 Form 的 labelCol 进行统一设置。当和 Form 同时设置时，以 FormItem 为准。 | [object](https://ant.design/components/grid/#Col) |  |  |
-| required | 是否必填，如不设置，则会根据校验规则自动生成 | boolean | false |  |
-| validateStatus | 校验状态，如不设置，则会根据校验规则自动生成，可选：'success' 'warning' 'error' 'validating' | string |  |  |
-| wrapperCol | 需要为输入控件设置布局样式时，使用该属性，用法同 labelCol。在 3.14.0 之后，你可以通过 Form 的 labelCol 进行统一设置。当和 Form 同时设置时，以 FormItem 为准。 | [object](https://ant.design/components/grid/#Col) |  |  |

-### 校验规则
-
-| 参数 | 说明 | 类型 | 默认值 |
-| --- | --- | --- | --- |
-| enum | 枚举类型 | string | - |
-| len | 字段长度 | number | - |
-| max | 最大长度 | number | - |
-| message | 校验文案 | string\|ReactNode | - |
-| min | 最小长度 | number | - |
-| pattern | 正则表达式校验 | RegExp | - |
-| required | 是否必选 | boolean | `false` |
-| transform | 校验前转换字段值 | function(value) => transformedValue:any | - |
-| type | 内建校验类型，[可选项](https://github.com/yiminghe/async-validator#type) | string | 'string' |
-| validator | 自定义校验（注意，[callback 必须被调用](https://github.com/ant-design/ant-design/issues/5155)） | function(rule, value, callback) | - |
-| whitespace | 必选时，空格是否会被视为错误 | boolean | `false` |
-

 title: Form
 ---
 
-Form is used to collect, validate, and submit the user input, usually contains various form items including checkbox, radio, input, select, and etc.
+High performance Form component with data scope management. Including data collection, verification, and styles.
 
 ## When to use
 
 - When you need to create a instance or collect information.
 - When you need to validate fields in certain rules.
 
-## Form Component
-
-You can align the controls of a `form` using the `layout` prop：
-
-- `horizontal`：to horizontally align the `label`s and controls of the fields. (Default)
-- `vertical`：to vertically align the `label`s and controls of the fields.
-- `inline`：to render form fields in one line.
-
-## Form Item Component
-
-A form consists of one or more form fields whose type includes input, textarea, checkbox, radio, select, tag, and more. A form field is defined using `<Form.Item />`.
-
-```jsx
-<Form.Item {...props}>{children}</Form.Item>
-```
-
 ## API

-| labelCol | (Added in 3.14.0. Previous version can only set on FormItem.) The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>` | [object](https://ant.design/components/grid/#Col) |  |
-| layout | Define form layout | 'horizontal'\|'vertical'\|'inline' | 'horizontal' |
-| onSubmit | Defines a function will be called if form data validation is successful. | Function(e:Event) |  |
-| wrapperCol | (Added in 3.14.0. Previous version can only set on FormItem.) The layout for input controls, same as `labelCol` | [object](https://ant.design/components/grid/#Col) |  |
-| colon | change default props colon value of Form.Item | boolean | true |
+| component | Set the Form rendering element. Do not create a DOM node for `false` | ComponentType \| false | form |
+| colon | Configure the default value of `colon` for Form.Item. Indicates whether the colon after the label is displayed | boolean | true |
+| fields | Control of form fields through state management (such as redux). Not recommended for non-strong demand. View [example](#components-form-demo-global-state) | [FieldData](#FieldData)\[] | - |
+| form | Form control instance created by `Form.useForm()`. Automatically created when not provided | [FormInstance](#FormInstance) | - |
+| hideRequiredMark | Hide required mark for all form items | boolean | false |
+| initialValues | Set value by Form initialization or reset | object | - |
+| labelAlign | Label text alignment | 'left' \| 'right' | 'right' |
+| labelCol | label layout, like `<Col>` component. Set `span` `offset` value like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` | [object](https://ant.design/components/grid/#Col) |  |
+| layout | Form layout | 'horizontal'\|'vertical'\|'inline' | 'horizontal' |
+| name | Form name. Will be the prefix of Field `id` | string | - |
+| validateMessages | 验证提示模板，说明[见下](#validateMessages) | [ValidateMessages](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts) | - |
+| wrapperCol | The layout for input controls, same as `labelCol` | [object](https://ant.design/components/grid/#Col) |  |

+| onFieldsChange | Trigger when field updated | Function(changedFields, allFields) | - |
+| onValuesChange | Trigger when value updated | Function(changedValues, allValues) | - |
+
+### validateMessages
+
+Form provides [default verification error messages](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts). You can modify template by configuring `validateMessages` property. A common usage is to configure localization:
 
-### Form.create(options)
+```jsx
+const validateMessages = {
+  required: "'${name}' is required!",
+  // ...
+};
 
-How to use：
+<Form validateMessages={validateMessages} />;
+```
+
+Besides,[ConfigProvider](/components/config-provider/) also provides a global configuration scheme that allows for uniform configuration error notification templates:
 
 ```jsx
-class CustomizedForm extends React.Component {}
+const validateMessages = {
+  required: "'${name}' is Required!",
+  // ...
+};
 
-CustomizedForm = Form.create({})(CustomizedForm);
+<ConfigProvider form={{ validateMessages }}>
+  <Form />
+</ConfigProvider>;
 ```
 
-The following `options` are available:
+## Form.Item
 
-| Property | Description | Type |
-| --- | --- | --- |
-| mapPropsToFields | Convert props to field value(e.g. reading the values from Redux store). And you must mark returned fields with [`Form.createFormField`](#Form.createFormField). Please note that the form fields will become controlled components. Properties like errors will not be automatically mapped and need to be manually passed in. | (props) => ({ \[fieldName\]: FormField { value } }) |
-| name | Set the id prefix of fields under form | - |
-| validateMessages | Default validate message. And its format is similar with [newMessages](https://github.com/yiminghe/async-validator/blob/master/src/messages.js)'s returned value | Object { \[nested.path]: String } |
-| onFieldsChange | Specify a function that will be called when the fields (including errors) of a `Form.Item` gets changed. Usage example: saving the field's value to Redux store. | Function(props, changedFields, allFields) |
-| onValuesChange | A handler while value of any field is changed | (props, changedValues, allValues) => void |
+Form field component for data bidirectional binding, validation, layout, and so on.
 
-If you want to get `ref` after `Form.create`, you can use `wrappedComponentRef` provided by `rc-form`, [details can be viewed here](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140).
+| Property | Description | Type | Default |
+| --- | --- | --- | --- |
+| colon | Used with `label`, whether to display `:` after label text. | boolean | true |
+| dependencies | Set the dependency field. See [below](#dependencies) | [NamePath](#NamePath)[] | - |
+| extra | The extra prompt message. It is similar to help. Usage example: to display error message and prompt message at the same time | string\|ReactNode | - |
+| getValueFromEvent | Specify how to get value from event or other onChange arguments | (..args: any[]) => any | - |
+| hasFeedback | Used with `validateStatus`, this option specifies the validation status icon. Recommended to be used only with `Input` | boolean | false |
+| help | The prompt message. If not provided, the prompt message will be generated by the validation rule. | string\|ReactNode | - |
+| htmlFor | Set sub label `htmlFor` | string | - |
+| inline | No style for `true`, used as a pure field control | boolean | false |
+| label | Label text | string\|ReactNode | - |
+| labelCol | The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>`. You can set `labelCol` on Form. If both exists, use Item first | [object](/components/grid/#Col) | - |
+| name | Field name, support array | [NamePath](#NamePath) | - |
+| normalize | Normalize value to form component | (value, prevValue, prevValues) => any | - |
+| required | Whether provided or not, it will be generated by the validation rule | boolean | false |
+| rules | Rules for field validation. Click [here](#components-form-demo-basic) to see an example | [Rule](#Rule)[] | - |
+| shouldUpdate | Custom field update logic. See [bellow](#shouldUpdate) | boolean \| (prevValue, curValue) => boolean | false |
+| trigger | When to collect the value of children node | string | onChange |
+| validateStatus | The validation status. If not provided, it will be generated by validation rule. options: 'success' 'warning' 'error' 'validating' | string |  |
+| validateTrigger | When to validate the value of children node | string \| string[] | onChange |
+| valuePropName | Props of children node, for example, the prop of Switch is 'checked' | string | value |
+| wrapperCol | The layout for input controls, same as `labelCol`. You can set `wrapperCol` on Form. If both exists, use Item first | [object](/components/grid/#Col) |  |
+
+### dependencies
+
+Used when there are dependencies between fields. If a field has the `dependencies` prop, this field will automatically trigger updates and validations when upstream updated. A common scenario is user register form with "password" and "confirm password" fields. The "Confirm Password" validation depends on the "Password" field. After setting `dependencies`, the "Password" field update will re-trigger the validation of "Check Password". You can refer [examples](#components-form-demo-register).
+
+### shouldUpdate
+
+Form updates only the modified field-related components for performance optimization purposes by incremental update. In most case, you only need to write code or do validation with the [`dependencies`](#dependencies) property. And in some specific case, such as a new field option appears with a filed value changed, or just want to keep some area updating by form update. You can modify the update logic of Form.Item via the `shouldUpdate`.
+
+When `shouldUpdate` is `true`, any Form update will cause the Form.Item to be re-rendered. This is very helpful for custom rendering some areas:
 
 ```jsx
-class CustomizedForm extends React.Component { ... }
-
-// use wrappedComponentRef
-const EnhancedForm =  Form.create()(CustomizedForm);
-<EnhancedForm wrappedComponentRef={(form) => this.form = form} />
-this.form // => The instance of CustomizedForm
+<Form.Item shouldUpdate>
+  {() => {
+    return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
+  }}
+</Form.Item>
 ```
 
-If the form has been decorated by `Form.create` then it has `this.props.form` property. `this.props.form` provides some APIs as follows:
+You can ref [example](#components-form-demo-horizontal-login) to see detail.
 
-> Note: Before using `getFieldsValue` `getFieldValue` `setFieldsValue` and so on, please make sure that corresponding field had been registered with `getFieldDecorator`.
-
-| Method | Description | Type |
-| --- | --- | --- |
-| getFieldDecorator | Two-way binding for form, please read below for details. |  |
-| getFieldError | Get the error of a field. | Function(name) |
-| getFieldsError | Get the specified fields' error. If you don't specify a parameter, you will get all fields' error. | Function(\[names: string\[]]) |
-| getFieldsValue | Get the specified fields' values. If you don't specify a parameter, you will get all fields' values. | Function(\[fieldNames: string\[]]) |
-| getFieldValue | Get the value of a field. | Function(fieldName: string) |
-| isFieldsTouched | Check whether any of fields is touched by `getFieldDecorator`'s `options.trigger` event | (names?: string\[]) => boolean |
-| isFieldTouched | Check whether a field is touched by `getFieldDecorator`'s `options.trigger` event | (name: string) => boolean |
-| isFieldValidating | Check if the specified field is being validated. | Function(name) |
-| resetFields | Reset the specified fields' value(to `initialValue`) and status. If you don't specify a parameter, all the fields will be reset. | Function(\[names: string\[]]) |
-| setFields | Set value and error state of fields. [Code Sample](https://github.com/react-component/form/blob/3b9959b57ab30b41d8890ff30c79a7e7c383cad3/examples/server-validate.js#L74-L79) | ({<br />&nbsp;&nbsp;\[fieldName\]: {value: any, errors: \[Error\] }<br />}) => void |
-| setFieldsValue | Set the value of a field. (Note: please don't use it in `componentWillReceiveProps`, otherwise, it will cause an endless loop, [reason](https://github.com/ant-design/ant-design/issues/2985)) | ({ \[fieldName\]&#x3A; value }) => void |
-| validateFields | Validate the specified fields and get theirs values and errors. If you don't specify the parameter of fieldNames, you will validate all fields. | (<br />&nbsp;&nbsp;\[fieldNames: string\[]],<br />&nbsp;&nbsp;\[options: object\],<br />&nbsp;&nbsp;callback(errors, values)<br />) => void |
-| validateFieldsAndScroll | This function is similar to `validateFields`, but after validation, if the target field is not in visible area of form, form will be automatically scrolled to the target field area. | same as `validateFields` |
-
-### validateFields/validateFieldsAndScroll
+When `shouldUpdate` is a function, it will be called by form values update. Providing original values and current value to compare. This is very helpful for rendering additional fields based on values:
 
 ```jsx
-const {
-  form: { validateFields },
-} = this.props;
-validateFields((errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], (errors, values) => {
-  // ...
-});
-validateFields(['field1', 'field2'], options, (errors, values) => {
-  // ...
-});
+<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
+  {() => {
+    return (
+      <Form.Item name="other">
+        <Input />
+      </Form.Item>
+    );
+  }}
+</Form.Item>
 ```
 
-| Method | Description | Type | Default |
+You can ref [example](#components-form-demo-control-hooks) to see detail.
+
+## Form.List

+  )}
+</Form.List>
+```
 
-  ```js
-  {
-    "username": "username",
-    "password": "password",
-  }
-  ```
+## Form.Provider
 
-### Form.createFormField
+Provide linkage between forms. If a sub form with `name` prop update, it will auto trigger Provider related events. See [example](#components-form-demo-form-context).
 
-To mark the returned fields data in `mapPropsToFields`, [demo](#components-form-demo-global-state).
+| Property | Description | Type | Default |
+| --- | --- | --- | --- |
+| onFormChange | Triggered when a sub form field updates | Function(formName: string, info: { changedFields, forms }) | - |
+| onFormFinish | Triggered when a sub form submits | Function(formName: string, info: { values, forms }) | - |
 
-### this.props.form.getFieldDecorator(id, options)
+```jsx
+<Form.Provider
+  onFormFinish={name => {
+    if (name === 'form1') {
+      // Do something...
+    }
+  }}
+>
+  <Form name="form1">...</Form>
+  <Form name="form2">...</Form>
+</Form.Provider>
+```
 
-After wrapped by `getFieldDecorator`, `value`(or other property defined by `valuePropName`) `onChange`(or other property defined by `trigger`) props will be added to form controls, the flow of form data will be handled by Form which will cause:
+### FormInstance
 
-1. You shouldn't use `onChange` to collect data, but you still can listen to `onChange`(and so on) events.
-2. You cannot set value of form control via `value` `defaultValue` prop, and you should set default value with `initialValue` in `getFieldDecorator` instead.
-3. You shouldn't call `setState` manually, please use `this.props.form.setFieldsValue` to change value programmatically.
+| Name | Description | Type |
+| --- | --- | --- |
+| getFieldValue | Get the value by the field name | (name: [NamePath](#NamePath)) => any |
+| getFieldsValue | Get values by a set of field names. Return according to the corresponding structure | (nameList?: [NamePath](#NamePath)[]) => any |
+| getFieldError | Get the error messages by the field name | (name: [NamePath](#NamePath)) => string[] |
+| getFieldsError | Get the error messages by the fields name. Return as an array | (nameList?: [NamePath](#NamePath)[]) => FieldError[] |
+| isFieldTouched | Check if a field has been operated | (name: [NamePath](#NamePath)) => boolean |
+| isFieldsTouched | Check if fields have been operated. Check if all fields is touched when `allTouched` is `true` | (nameList?: [NamePath](#NamePath)[], allTouched?: boolean) => boolean |
+| isFieldValidating | Check fields if is in validating | (name: [NamePath](#NamePath)) => boolean |
+| resetFields | Reset fields to `initialValues` | (fields?: [NamePath](#NamePath)[]) => void |
+| setFields | Set fields status | (fields: FieldData[]) => void |
+| setFieldsValue | Set fields value | (values) => void |
+| submit | Submit the form. It's same as click `submit` button | () => void |
+| validateFields | Validate fields | (nameList?: [NamePath](#NamePath)[]) => Promise |
+
+#### validateFields return sample
 
-#### Special attention
+```jsx
+validateFields()
+  .then(values => {
+    /*
+  values:
+    {
+      username: 'username',
+      password: 'password',

-具有数据收集、校验和提交功能的表单，包含复选框、单选框、输入框、下拉选择框等元素。
+高性能表单控件，自带数据域管理。包含数据录入、校验以及对应样式。
 
 ## 何时使用
 
 - 用于创建一个实体或收集信息。
 - 需要对输入的数据类型进行校验时。
 
-## 表单
-
-我们为 `form` 提供了以下三种排列方式：
-
-- 水平排列：标签和表单控件水平排列；（默认）
-- 垂直排列：标签和表单控件上下垂直排列；
-- 行内排列：表单项水平行内排列。
-
-## 表单域
-
-表单一定会包含表单域，表单域可以是输入控件，标准表单域，标签，下拉菜单，文本域等。
-
-这里我们封装了表单域 `<Form.Item />` 。
-
-```jsx
-<Form.Item {...props}>{children}</Form.Item>
-```
-
 ## API
 
 ### Form
 
-**更多示例参考 [rc-form](http://react-component.github.io/form/)**。
-
 | 参数 | 说明 | 类型 | 默认值 |
 | --- | --- | --- | --- |
-| form | 经 `Form.create()` 包装过的组件会自带 `this.props.form` 属性 | object | - |
-| hideRequiredMark | 隐藏所有表单项的必选标记 | Boolean | false |
+| component | 设置 Form 渲染元素，为 `false` 则不创建 DOM 节点 | ComponentType \| false | form |
+| colon | 配置 Form.Item 的 `colon` 的默认值。表示是否显示 label 后面的冒号 | boolean | true |
+| fields | 通过状态管理（如 redux）控制表单字段，如非强需求不推荐使用。查看[示例](#components-form-demo-global-state) | [FieldData](#FieldData)\[] | - |
+| form | 经 `Form.useForm()` 创建的 form 控制实例，不提供时会自动创建 | [FormInstance](#FormInstance) | - |
+| hideRequiredMark | 隐藏所有表单项的必选标记 | boolean | false |
+| initialValues | 表单默认值，只有初始化以及重置时生效 | object | - |
 | labelAlign | label 标签的文本对齐方式 | 'left' \| 'right' | 'right' |
-| labelCol | （3.14.0 新增，之前的版本只能设置到 FormItem 上。）label 标签布局，同 `<Col>` 组件，设置 `span` `offset` 值，如 `{span: 3, offset: 12}` 或 `sm: {span: 3, offset: 12}` | [object](https://ant.design/components/grid/#Col) |  |
+| labelCol | label 标签布局，同 `<Col>` 组件，设置 `span` `offset` 值，如 `{span: 3, offset: 12}` 或 `sm: {span: 3, offset: 12}` | [object](https://ant.design/components/grid/#Col) |  |
 | layout | 表单布局 | 'horizontal'\|'vertical'\|'inline' | 'horizontal' |
-| onSubmit | 数据验证成功后回调事件 | Function(e:Event) |  |
-| wrapperCol | （3.14.0 新增，之前的版本只能设置到 FormItem 上。）需要为输入控件设置布局样式时，使用该属性，用法同 labelCol | [object](https://ant.design/components/grid/#Col) |  |
-| colon | 配置 Form.Item 的 colon 的默认值 | boolean | true |
+| name | 表单名称，会作为表单字段 `id` 前缀使用 | string | - |
+| validateMessages | 验证提示模板，说明[见下](#validateMessages) | [ValidateMessages](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts) | - |
+| wrapperCol | 需要为输入控件设置布局样式时，使用该属性，用法同 labelCol | [object](https://ant.design/components/grid/#Col) |  |
+| onFinish | 提交表单且数据验证成功后回调事件 | Function(values) | - |
+| onFinishFailed | 提交表单且数据验证失败后回调事件 | Function({ values, errorFields, outOfDate }) | - |
+| onFieldsChange | 字段更新时触发回调事件 | Function(changedFields, allFields) | - |
+| onValuesChange | 字段值更新时触发回调事件 | Function(changedValues, allValues) | - |
 
-### Form.create(options)
+### validateMessages
 
-使用方式如下：
+Form 为验证提供了[默认的错误提示信息](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts)，你可以通过配置 `validateMessages` 属性，修改对应的提示模板。一种常见的使用方式，是配置国际化提示信息：
 
 ```jsx
-class CustomizedForm extends React.Component {}
+const validateMessages = {
+  required: "'${name}' 是必选字段",
+  // ...
+};
 
-CustomizedForm = Form.create({})(CustomizedForm);
+<Form validateMessages={validateMessages} />;
 ```
 
-`options` 的配置项如下。
-
-| 参数 | 说明 | 类型 |
-| --- | --- | --- |
-| mapPropsToFields | 把父组件的属性映射到表单项上（如：把 Redux store 中的值读出），需要对返回值中的表单域数据用 [`Form.createFormField`](#Form.createFormField) 标记，注意表单项将变成受控组件, error 等也需要一并手动传入 | (props) => ({ \[fieldName\]: FormField { value } }) |
-| name | 设置表单域内字段 id 的前缀 | - |
-| validateMessages | 默认校验信息，可用于把默认错误信息改为中文等，格式与 [newMessages](https://github.com/yiminghe/async-validator/blob/master/src/messages.js) 返回值一致 | Object { \[nested.path]: String } |
-| onFieldsChange | 当 `Form.Item` 子节点的值（包括 error）发生改变时触发，可以把对应的值转存到 Redux store | Function(props, changedFields, allFields) |
-| onValuesChange | 任一表单域的值发生改变时的回调 | (props, changedValues, allValues) => void |
-
-经过 `Form.create` 之后如果要拿到 `ref`，可以使用 `rc-form` 提供的 `wrappedComponentRef`，[详细内容可以查看这里](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140)。
+此外，[ConfigProvider](/components/config-provider/) 也提供了全局化配置方案，允许统一配置错误提示模板：
 
 ```jsx
-class CustomizedForm extends React.Component { ... }
+const validateMessages = {
+  required: "'${name}' 是必选字段",
+  // ...
+};
 
-// use wrappedComponentRef
-const EnhancedForm =  Form.create()(CustomizedForm);
-<EnhancedForm wrappedComponentRef={(form) => this.form = form} />
-this.form // => The instance of CustomizedForm
+<ConfigProvider form={{ validateMessages }}>
+  <Form />
+</ConfigProvider>;
 ```
 
-经过 `Form.create` 包装的组件将会自带 `this.props.form` 属性，`this.props.form` 提供的 API 如下：
-
-> 注意：使用 `getFieldsValue` `getFieldValue` `setFieldsValue` 等时，应确保对应的 field 已经用 `getFieldDecorator` 注册过了。

-| setFieldsValue | 设置一组输入控件的值（注意：不要在 `componentWillReceiveProps` 内使用，否则会导致死循环，[原因](https://github.com/ant-design/ant-design/issues/2985)） | ({ \[fieldName\]&#x3A; value }) => void |
-| validateFields | 校验并获取一组输入域的值与 Error，若 fieldNames 参数为空，则校验全部组件 | (<br />&nbsp;&nbsp;\[fieldNames: string\[]],<br />&nbsp;&nbsp;\[options: object\],<br />&nbsp;&nbsp;callback(errors, values)<br />) => void |
-| validateFieldsAndScroll | 与 `validateFields` 相似，但校验完后，如果校验不通过的菜单域不在可见范围内，则自动滚动进可见范围 | 参考 `validateFields` |

+
+### dependencies
+
+当字段间存在依赖关系时使用。如果一个字段设置了 `dependencies` 属性。那么它所依赖的字段更新时，该字段将自动触发更新与校验。一种常见的场景，就是注册用户表单的“密码”与“确认密码”字段。“确认密码”校验依赖于“密码”字段，设置 `dependencies` 后，“密码”字段更新会重新触发“校验密码”的校验逻辑。你可以参考[具体例子](#components-form-demo-register)。
+
+### shouldUpdate
+
+Form 通过增量更新方式，只更新被修改的字段相关组件以达到性能优化目的。大部分场景下，你只需要编写代码或者与 [`dependencies`](#dependencies) 属性配合校验即可。而在某些特定场景，例如修改某个字段值后出现新的字段选项、或者纯粹希望表单任意变化都对某一个区域进行渲染。你可以通过 `shouldUpdate` 修改 Form.Item 的更新逻辑。
+
+当 `shouldUpdate` 为 `true` 时，Form 的任意变化都会使该 Form.Item 重新渲染。这对于自定义渲染一些区域十分有帮助：
 
-- `values`:
+```jsx
+<Form.Item shouldUpdate>
+  {() => {
+    return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
+  }}
+</Form.Item>
+```
 
-  ```js
-  {
-    "username": "username",
-    "password": "password",
-  }
-  ```
+你可以参考[示例](#components-form-demo-horizontal-login)查看具体使用场景。
 
-### Form.createFormField
+当 `shouldUpdate` 为方法时，表单的每次数值更新都会调用该方法，提供原先的值与当前的值以供你比较是否需要更新。这对于是否根据值来渲染额外字段十分有帮助：
 
-用于标记 `mapPropsToFields` 返回的表单域数据，[例子](#components-form-demo-global-state)。
+```jsx
+<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
+  {() => {
+    return (
+      <Form.Item name="other">
+        <Input />
+      </Form.Item>
+    );
+  }}
+</Form.Item>
+```
 
-### this.props.form.getFieldDecorator(id, options)
+你可以参考[示例](#components-form-demo-control-hooks)查看具体使用场景。
 
-经过 `getFieldDecorator` 包装的控件，表单控件会自动添加 `value`（或 `valuePropName` 指定的其他属性） `onChange`（或 `trigger` 指定的其他属性），数据同步将被 Form 接管，这会导致以下结果：
+## Form.List
 
-1. 你**不再需要也不应该**用 `onChange` 来做同步，但还是可以继续监听 `onChange` 等事件。
-2. 你不能用控件的 `value` `defaultValue` 等属性来设置表单域的值，默认值可以用 `getFieldDecorator` 里的 `initialValue`。
-3. 你不应该用 `setState`，可以使用 `this.props.form.setFieldsValue` 来动态改变表单值。
+为字段提供数组化管理。
 
-#### 特别注意
+| 参数 | 说明 | 类型 | 默认值 |
+| --- | --- | --- | --- |
+| name | 字段名，支持数组 | [NamePath](#NamePath) | - |
+| children | 渲染函数 | (fields: Field[], operation: { add, remove }) => React.ReactNode | - |
 
-如果使用的是 `react@<15.3.0`，则 `getFieldDecorator` 调用不能位于纯函数组件中: <https://github.com/facebook/react/pull/6534>
+```tsx
+<Form.List>
+  {fields => (
+    <div>
+      {fields.map(field => (
+        <Form.Item {...field}>
+          <Input />
+        </Form.Item>
+      ))}
+    </div>
+  )}
+</Form.List>
+```
 
-#### getFieldDecorator(id, options) 参数
+## Form.Provider
 
-| 参数 | 说明 | 类型 | 默认值 |
-| --- | --- | --- | --- |
-| id | 必填输入控件唯一标志。支持嵌套式的[写法](https://github.com/react-component/form/pull/48)。 | string |  |
-| options.getValueFromEvent | 可以把 onChange 的参数（如 event）转化为控件的值 | function(..args) | [reference](https://github.com/react-component/form#option-object) |
-| options.initialValue | 子节点的初始值，类型、可选值均由子节点决定(注意：由于内部校验时使用 `===` 判断是否变化，建议使用变量缓存所需设置的值而非直接使用字面量)) |  |  |
-| options.normalize | 转换默认的 value 给控件，[一个选择全部的例子](https://codepen.io/afc163/pen/JJVXzG?editors=001) | function(value, prevValue, allValues): any | - |
-| options.preserve | 即便字段不再使用，也保留该字段的值 | boolean | - |
-| options.rules | 校验规则，参考下方文档 | object\[] |  |
-| options.trigger | 收集子节点的值的时机 | string | 'onChange' |
-| options.validateFirst | 当某一规则校验不通过时，是否停止剩下的规则的校验 | boolean | false |
-| options.validateTrigger | 校验子节点值的时机 | string\|string\[] | 'onChange' |
-| options.valuePropName | 子节点的值的属性，如 Switch 的是 'checked' | string | 'value' |
-
-更多参数请查看 [rc-form option](https://github.com/react-component/form#option-object)。
-
-### Form.Item
-
-注意：一个 Form.Item 建议只放一个被 getFieldDecorator 装饰过的 child，当有多个被装饰过的 child 时，`help` `required` `validateStatus` 无法自动生成。

-| labelCol | label 标签布局，同 `<Col>` 组件，设置 `span` `offset` 值，如 `{span: 3, offset: 12}` 或 `sm: {span: 3, offset: 12}`。在 3.14.0 之后，你可以通过 Form 的 labelCol 进行统一设置。当和 Form 同时设置时，以 FormItem 为准。 | [object](https://ant.design/components/grid/#Col) |  |  |
-| required | 是否必填，如不设置，则会根据校验规则自动生成 | boolean | false |  |
-| validateStatus | 校验状态，如不设置，则会根据校验规则自动生成，可选：'success' 'warning' 'error' 'validating' | string |  |  |
-| wrapperCol | 需要为输入控件设置布局样式时，使用该属性，用法同 labelCol。在 3.14.0 之后，你可以通过 Form 的 labelCol 进行统一设置。当和 Form 同时设置时，以 FormItem 为准。 | [object](https://ant.design/components/grid/#Col) |  |  |
-
-### 校验规则
+提供表单间联动功能，其下设置 `name` 的 Form 更新时，会自动触发对应事件。查看[示例](#components-form-demo-form-context)。
 
 | 参数 | 说明 | 类型 | 默认值 |
 | --- | --- | --- | --- |
-| enum | 枚举类型 | string | - |
-| len | 字段长度 | number | - |
-| max | 最大长度 | number | - |
-| message | 校验文案 | string\|ReactNode | - |
-| min | 最小长度 | number | - |
-| pattern | 正则表达式校验 | RegExp | - |
-| required | 是否必选 | boolean | `false` |
-| transform | 校验前转换字段值 | function(value) => transformedValue:any | - |
-| type | 内建校验类型，[可选项](https://github.com/yiminghe/async-validator#type) | string | 'string' |
-| validator | 自定义校验（注意，[callback 必须被调用](https://github.com/ant-design/ant-design/issues/5155)） | function(rule, value, callback) | - |
-| whitespace | 必选时，空格是否会被视为错误 | boolean | `false` |
-
-更多高级用法可研究 [async-validator](https://github.com/yiminghe/async-validator)。

-## 在 TypeScript 中使用
+| onFormChange | 子表单字段更新时触发 | Function(formName: string, info: { changedFields, forms }) | - |
+| onFormFinish | 子表单提交时触发 | Function(formName: string, info: { values, forms }) | - |
 
-```tsx
-import { Form } from 'antd';
-import { FormComponentProps } from 'antd/lib/form';
+```jsx
+<Form.Provider
+  onFormFinish={name => {
+    if (name === 'form1') {
+      // Do something...
+    }
+  }}
+>
+  <Form name="form1">...</Form>
+  <Form name="form2">...</Form>
+</Form.Provider>
+```
 
-interface UserFormProps extends FormComponentProps {
-  age: number;
-  name: string;
-}
+### FormInstance
 
-class UserForm extends React.Component<UserFormProps, any> {
-  // ...
-}
+| 名称 | 说明 | 类型 |
+| --- | --- | --- |
+| getFieldValue | 获取对应字段名的值 | (name: [NamePath](#NamePath)) => any |
+| getFieldsValue | 获取一组字段名对应的值，会按照对应结构返回 | (nameList?: [NamePath](#NamePath)[]) => any |
+| getFieldError | 获取对应字段名的错误信息 | (name: [NamePath](#NamePath)) => string[] |
+| getFieldsError | 获取一组字段名对应的错误信息，返回为数组形式 | (nameList?: [NamePath](#NamePath)[]) => FieldError[] |
+| isFieldTouched | 检查对应字段是否被用户操作过 | (name: [NamePath](#NamePath)) => boolean |
+| isFieldsTouched | 检查一组字段是否被用户操作过，`allTouched` 为 `true` 时检查是否所有字段都被操作过 | (nameList?: [NamePath](#NamePath)[], allTouched?: boolean) => boolean |
+| isFieldValidating | 检查一组字段是否正在校验 | (name: [NamePath](#NamePath)) => boolean |
+| resetFields | 重置一组字段到 `initialValues` | (fields?: [NamePath](#NamePath)[]) => void |
+| setFields | 设置一组字段状态 | (fields: FieldData[]) => void |
+| setFieldsValue | 设置表单的值 | (values) => void |
+| submit | 提交表单，与点击 `submit` 按钮效果相同 | () => void |
+| validateFields | 触发表单验证 | (nameList?: [NamePath](#NamePath)[]) => Promise |
+
+#### validateFields 返回示例
 
-const App = Form.create<UserFormProps>({
-  // ...
-})(UserForm);
+```jsx
+validateFields()
+  .then(values => {
+    /*
+  values:
+    {
+      username: 'username',
+      password: 'password',
+    }
+  */
+  })
+  .catch(errorInfo => {
+    /*
+    errorInfo:
+      {
+        values: {
+          username: 'username',
+          password: 'password',
+        },
+        errorFields: [
+          { password: ['username'], errors: ['Please input your Password!'] },
+        ],
+        outOfDate: false,
+      }
+    */
+  });
 ```
 
+### Interface
+
+#### NamePath
+
+`string | number | (string | number)[]`
+
+#### FieldData
+
+| 名称       | 说明             | 类型                    |
+| ---------- | ---------------- | ----------------------- |
+| touched    | 是否被用户操作过 | boolean                 |
+| validating | 是否正在校验     | boolean                 |
+| errors     | 错误信息         | string[]                |
+| name       | 字段名称         | [NamePath](#NamePath)[] |
+| value      | 字段对应值       | any                     |
+
+#### Rule
+
+| 名称 | 说明 | 类型 |
+| --- | --- | --- |
+| enum | 是否匹配枚举中的值 | any[] |
+| len | string 类型时为字符串长度；number 类型时为确定数字； array 类型时为数组长度 | number |
+| max | string 类型为字符串最大长度；number 类型时为最大值；array 类型时为数组最大长度 | number |
+| message | 错误信息，不设置时会通过[模板](#validateMessages)自动生成 | string |
+| min | string 类型为字符串最小长度；number 类型时为最小值；array 类型时为数组最小长度 | number |
+| pattern | 正则表达式匹配 | RegExp |
+| required | 是否为必选字段 | boolean |
+| transform | 将字段值转换成目标值后进行校验 | (value) => any |
+| type | 类型，常见有 `string` \|`number` \|`boolean` \|`url` \| `email`。更多请参考[此处](https://github.com/yiminghe/async-validator#type) | string |
+| validator | 自定义校验，接收 Promise 作为返回值。[示例](#components-form-demo-register)参考 | ([rule](#Rule), value) => Promise |
+| whitespace | 如果字段仅包含空格则校验不通过 | boolean |
+| validateTrigger | 设置触发验证时机，必须是 Form.Item 的 `validateTrigger` 的子集 | string \| string[] |
+

+title: Migrate to v4
+skip: true
+---
+
+### Remove Form.create
+
+Form of v4 is not need create context by `Form.create()`. Form is now have own data scope and you don't need `getFieldDecorator` anymore. Just use Form.Item directly:
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator } }) => (
+  <Form>
+    <Form.Item>
+      {getFieldDecorator('username', {
+        rules: [{ required: true }],
+      })(<Input />)}
+    </Form.Item>
+  </Form>
+);
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+To:
+
+```jsx
+// antd v4
+const Demo = () => (
+  <Form>
+    <Form.Item name="username" rules={[{ required: true }]}>
+      <Input />
+    </Form.Item>
+  </Form>
+);
+```
+
+Since `Form.create()` is removed, origin `onFieldsChange` or other methods moved to Form, and control by `fields`. ref [example](/components/form/#components-form-demo-global-state)。
+
+### Form control
+
+If you want to control form, you can use `Form.useForm()` to create Form instance for operation:
+
+```jsx
+// antd v3
+const Demo = ({ form: { setFieldsValue } }) => {
+  React.useEffect(() => {
+    setFieldsValue({
+      username: 'Bamboo',
+    });
+  }, []);
+
+  return (
+    <Form>
+      <Form.Item>
+        {getFieldDecorator('username', {
+          rules: [{ required: true }],
+        })(<Input />)}
+      </Form.Item>
+    </Form>
+  );
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+To:
+
+```jsx
+// antd v4
+const Demo = () => {
+  const [form] = Form.useForm();
+
+  React.useEffect(() => {
+    form.setFieldsValue({
+      username: 'Bamboo',
+    });
+  }, []);
+
+  return (
+    <Form form={form}>
+      <Form.Item name="username" rules={[{ required: true }]}>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+For class component, you can use `ref` to access instance:
+
+```jsx
+// antd v4
+class Demo extends React.Component {
+  formRef = React.createRef();
+
+  componentDidMount() {
+    this.formRef.setFieldsValue({
+      username: 'Bamboo',
+    });
+  }
+
+  render() {
+    return (
+      <Form ref={formRef}>
+        <Form.Item name="username" rules={[{ required: true }]}>
+          <Input />
+        </Form.Item>
+      </Form>
+    );
+  }
+}
+```
+
+If you don't want to use the Item style, you can use `inline` prop to remove it:
+
+```jsx
+// antd v3
+const Demo = ({ form: { setFieldsValue } }) => {
+  return <Form>{getFieldDecorator('username')(<Input />)}</Form>;
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+To:
+
+```jsx
+// antd v4
+const Demo = () => {
+  return (
+    <Form>
+      <Form.Item name="username" inline>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+### Linkage with field
+
+New Form use incremental update which only update related field. So if there are some linkage between fields or update with whole form. You can use [`dependencies`](/components/form/#dependencies) or [`shouldUpdate`](/components/form/#shouldUpdate) to handle that.
+
+### replace onSubmit with onFinish
+
+You need to listen `onSubmit` and call `validateFields` to handle validation in old Form. New Form provides `onFinish` which only trigger when validation is passed:
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator, validateFields } }) => {
+  const onSubmit = e => {
+    e.preventDefault();
+    validateFields((err, values) => {
+      if (!err) {
+        console.log('Received values of form: ', values);
+      }
+    });
+  };
+
+  return (
+    <Form onSubmit={onSubmit}>
+      <Form.Item>
+        {getFieldDecorator('username', {
+          rules: [{ required: true }],
+        })(<Input />)}
+      </Form.Item>
+    </Form>
+  );
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+To:
+
+```jsx
+// antd v4
+const Demo = () => {
+  const onFinish = values => {
+    console.log('Received values of form: ', values);
+  };
+
+  return (
+    <Form onFinish={onFinish}>
+      <Form.Item name="username" rules={[{ required: true }]}>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+### Initialization
+
+Besides, we move `initialValue` into Form to avoid field with same name both using `initialValue` to cause conflict:
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator } }) => (
+  <Form>
+    <Form.Item>
+      {getFieldDecorator('username', {
+        rules: [{ required: true }],
+        initialValue: 'Bamboo',
+      })(<Input />)}
+    </Form.Item>
+  </Form>
+);
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+To:
+
+```jsx
+// antd v4
+const Demo = () => (
+  <Form initialValues={{ username: 'Bamboo' }}>
+    <Form.Item name="username" rules={[{ required: true }]}>
+      <Input />
+    </Form.Item>
+  </Form>
+);
+```
+
+In v3, modifying the `initialValue` of un-operated field will update the field value synchronously, which is a bug. However, since it has been used as a feature for a long time, we have not fixed it. In v4, the bug has been fixed. `initialValues` only takes effect when initializing and resetting the form.
+
+### Remove field no longer removes field value
+
+In v3, we will clean up the values when the fields removed. However, it has been found that clearing fields can cause greater inconvenience than retention in practice. For example like some switching operations, the user has to retain the field value in a hidden way. Therefore, the new version of Form will always keep the fields value, and the validation rules for removing field will be ignored. So `preserve` is no longer needed.
+
+### Nested field paths using arrays
+
+In the past versions we used `.` to represent nested paths (such as `user.name` to represent `{ user: { name: '' } }`). However, in some backend systems, `.` is also included in the variable name. This causes the user to need additional code to convert, so in the new version, nested paths are represented by arrays to avoid unexpected behavior (eg `['user', 'name']`).
+
+Therefore, paths returned by methods such as `getFieldsError` are always in an array form for the user to handle:
+
+```jsx
+form.getFieldsError();
+
+/*
+[
+  { name: ['user', 'name'], errors: [] },
+  { name: ['user', 'age'], errors: ['Some error message'] },
+]
+*/
+```
+
+### Remove callback in validateFields
+
+`validateFields` will return a Promise, so you can handle the error with `async/await` or `then/catch`. It is no longer necessary to determine if `errors` is empty:
+
+```jsx
+// antd v3
+validateFields((err, value) => {
+  if (!err) {
+    // Do something with value
+  }
+});
+```
+
+To
+
+```jsx
+// antd v4
+validateFields().then(values => {
+  // Do something with value
+});
+```

+title: 从 v3 到 v4
+skip: true

+
+新版本 Form 对使用方式进行了简化，因而如果你是从 v3 迁移上来。你可以参考本文做迁移工作。
+
+## 去除 Form.create
+
+v4 的 Form 不再需要通过 `Form.create()` 创建上下文。Form 组件现在自带数据域，因而 `getFieldDecorator` 也不再需要，直接写入 Form.Item 即可：
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator } }) => (
+  <Form>
+    <Form.Item>
+      {getFieldDecorator('username', {
+        rules: [{ required: true }],
+      })(<Input />)}
+    </Form.Item>
+  </Form>
+);
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+改成：
+
+```jsx
+// antd v4
+const Demo = () => (
+  <Form>
+    <Form.Item name="username" rules={[{ required: true }]}>
+      <Input />
+    </Form.Item>
+  </Form>
+);
+```
+
+由于移除了 `Form.create()`，原本的 `onFieldsChange` 等方法移入 Form 中，通过 `fields` 对 Form 进行控制。参考[示例](/components/form/#components-form-demo-global-state)。
+
+## 表单控制调整
+
+Form 自带表单控制实体，如需要调用 form 方法，可以通过 `Form.useForm()` 创建 Form 实体进行操作：
+
+```jsx
+// antd v3
+const Demo = ({ form: { setFieldsValue } }) => {
+  React.useEffect(() => {
+    setFieldsValue({
+      username: 'Bamboo',
+    });
+  }, []);
+
+  return (
+    <Form>
+      <Form.Item>
+        {getFieldDecorator('username', {
+          rules: [{ required: true }],
+        })(<Input />)}
+      </Form.Item>
+    </Form>
+  );
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+改成：
+
+```jsx
+// antd v4
+const Demo = () => {
+  const [form] = Form.useForm();
+
+  React.useEffect(() => {
+    form.setFieldsValue({
+      username: 'Bamboo',
+    });
+  }, []);
+
+  return (
+    <Form form={form}>
+      <Form.Item name="username" rules={[{ required: true }]}>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+对于 class component，也可以通过 `ref` 获得实体：
+
+```jsx
+// antd v4
+class Demo extends React.Component {
+  formRef = React.createRef();
+
+  componentDidMount() {
+    this.formRef.setFieldsValue({
+      username: 'Bamboo',
+    });
+  }
+
+  render() {
+    return (
+      <Form ref={formRef}>
+        <Form.Item name="username" rules={[{ required: true }]}>
+          <Input />
+        </Form.Item>
+      </Form>
+    );
+  }
+}
+```
+
+由于 Form.Item 内置字段绑定，如果需要不带样式的表单绑定，可以使用 `inline` 属性移除额外样式：
+
+```jsx
+// antd v3
+const Demo = ({ form: { setFieldsValue } }) => {
+  return <Form>{getFieldDecorator('username')(<Input />)}</Form>;
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+改成：
+
+```jsx
+// antd v4
+const Demo = () => {
+  return (
+    <Form>
+      <Form.Item name="username" inline>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+## 字段联动调整
+
+新版 Form 采用增量更新方式，仅会更新需要更新的字段。因而如果有字段关联更新，或者跟随整个表单更新而更新。可以使用 [`dependencies`](/components/form/#dependencies) 或 [`shouldUpdate`](/components/form/#shouldUpdate)。
+
+## onFinish 替代 onSubmit
+
+对于表单校验，过去版本需要通过监听 `onSubmit` 事件手工触发 `validateFields`。新版直接使用 `onFinish` 事件，该事件仅当校验通过后才会执行：
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator, validateFields } }) => {
+  const onSubmit = e => {
+    e.preventDefault();
+    validateFields((err, values) => {
+      if (!err) {
+        console.log('Received values of form: ', values);
+      }
+    });
+  };
+
+  return (
+    <Form onSubmit={onSubmit}>
+      <Form.Item>
+        {getFieldDecorator('username', {
+          rules: [{ required: true }],
+        })(<Input />)}
+      </Form.Item>
+    </Form>
+  );
+};
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+改成：
+
+```jsx
+// antd v4
+const Demo = () => {
+  const onFinish = values => {
+    console.log('Received values of form: ', values);
+  };
+
+  return (
+    <Form onFinish={onFinish}>
+      <Form.Item name="username" rules={[{ required: true }]}>
+        <Input />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+## 初始化调整
+
+此外，我们将 `initialValue` 从字段中移到 Form 中。以避免同名字段设置 `initialValue` 的冲突问题：
+
+```jsx
+// antd v3
+const Demo = ({ form: { getFieldDecorator } }) => (
+  <Form>
+    <Form.Item>
+      {getFieldDecorator('username', {
+        rules: [{ required: true }],
+        initialValue: 'Bamboo',
+      })(<Input />)}
+    </Form.Item>
+  </Form>
+);
+
+const WrappedDemo = Form.create()(Demo);
+```
+
+改成：
+
+```jsx
+// antd v4
+const Demo = () => (
+  <Form initialValues={{ username: 'Bamboo' }}>
+    <Form.Item name="username" rules={[{ required: true }]}>
+      <Input />
+    </Form.Item>
+  </Form>
+);
+```
+
+在 v3 版本中，修改未操作的字段 `initialValue` 会同步更新字段值，这是一个 BUG。但是由于被长期作为一个 feature 使用，因而我们一直没有修复。在 v4 中，该 BUG 已被修复。`initialValue` 只有在初始化以及重置表单时生效。
+
+## 移除字段不再移除字段值
+
+v3 版本中，我们会将移除的字段对应的值同步清理。但是在实践中，发现清除字段相比保留会造成更大的不便。例如一些切换操作，用户不得不通过隐藏的方式保留字段值。因而新版本的 Form 总是会保留字段值，而移除字段的校验规则会被忽略。也因此 `preserve` 不再需要。
+
+## 嵌套字段路径使用数组
+
+过去版本我们通过 `.` 代表嵌套路径（诸如 `user.name` 来代表 `{ user: { name: '' } }`）。然而在一些后台系统中，变量名中也会带上 `.`。这造成用户需要额外的代码进行转化，因而新版中，嵌套路径通过数组来表示以避免错误的处理行为（如 `['user', 'name']`）。
+
+也因此，诸如 `getFieldsError` 等方法返回的路径总是数组形式以便于用户处理：
+
+```jsx
+form.getFieldsError();
+
+/*
+[
+  { name: ['user', 'name'], errors: [] },
+  { name: ['user', 'age'], errors: ['Some error message'] },
+]
+*/
+```
+
+## validateFields 不再支持 callback
+
+`validateFields` 会返回 Promise 对象，因而你可以通过 `async/await` 或者 `then/catch` 来执行对应的错误处理。不再需要判断 `errors` 是否为空：
+
+```jsx
+// antd v3
+validateFields((err, value) => {
+  if (!err) {
+    // Do something with value
+  }
+});
+```
+
+改成：
+
+```jsx
+// antd v4
+validateFields().then(values => {
+  // Do something with value
+});
+```
