### validateMessages
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
const validateMessages = {
required: "'${name}' 是必选字段",
// ...
};
<Form validateMessages={validateMessages} />;
```
此外,[ConfigProvider](/components/config-provider/) 也提供了全局化配置方案,允许统一配置错误提示模板:
```jsx
const validateMessages = {
required: "'${name}' 是必选字段",
// ...
};
<ConfigProvider form={{ validateMessages }}>
<Form />
</ConfigProvider>;
```
## Form.Item
表单字段组件,用于数据双向绑定、校验、布局等。
| 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 | |
| dependencies | 设置依赖字段,说明[见下](#dependencies) | [NamePath](#NamePath)[] | - | |
| 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 | - | |
| getValueFromEvent | 设置如何将 event 的值转换成字段值 | (..args: any[]) => any | - | |
