When requiring users to interact with the application, but without jumping to a new page and interrupting the user's workflow, you can use `Modal` to create a new floating layer over the current page to get user feedback or display information. Additionally, if you need show a simple confirmation dialog, you can use `antd.Modal.confirm()`, and so on.
> The state of Modal will be preserved at it's component lifecycle by default, if you wish to open it with a brand new state everytime, set `destroyOnClose` on it.
| width | Width of the modal dialog | string\|number | 416 | |
| zIndex | The `z-index` of the Modal | Number | 1000 | |
| onCancel | Specify a function that will be called when the user clicks the Cancel button. The parameter of this function is a function whose execution should include closing the dialog. You can also just return a promise and when the promise is resolved, the modal dialog will also be closed | function(close) | - | |
| onOk | Specify a function that will be called when the user clicks the OK button. The parameter of this function is a function whose execution should include closing the dialog. You can also just return a promise and when the promise is resolved, the modal dialog will also be closed | function(close) | - | |
`Modal.destroyAll()` could destroy all confirmation modal dialogs(Modal.info/Modal.success/Modal.error/Modal.warning/Modal.confirm). Usually, you can use it in router change event to destroy confirm modal dialog automatically without use modal reference to close( it's too complex to use for all modal dialogs)
When you need using Context, you can use `contextHolder` which created by `Modal.useModal` to insert into children. Modal created by hooks will get all the context where `contextHolder` are. Created `modal` has the same creating function with `Modal.method`](<#Modal.method()>).
### Why I can not access context, redux in Modal.xxx?
antd will dynamic create React instance by `ReactDOM.render` when call Modal methods. Whose context is different with origin code located context.
When you need context info (like ConfigProvider context), you can use `Modal.useModal` to get `modal` instance and `contextHolder` node. And put it in your children:
