Modal dialogs.
|
|
|
|
## When To Use
|
|
|
|
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.

#### Note
|
|
|
|
- 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.
|
|
- There is a situation that using `<Modal />` with Form, which won't clear fields value when closing Modal even you have set `destroyOnClose`. You need `<Form preserve={false} />` in this case.
|
|
- `Modal.method()` RTL mode only supports hooks.
|
|
|
|
### Modal.method()
|
|
|
|
There are five ways to display the information based on the content's nature:
|
|
|
|
- `Modal.info`
|
|
- `Modal.success`
|
|
- `Modal.error`
|
|
- `Modal.warning`
|
|
- `Modal.confirm`
|
|
|
|
The items listed above are all functions, expecting a settings object as parameter. The properties of the object are follows:
|
|
|
|
| Property | Description | Type | Default | Version |

|
|
| 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) | - | |
|
|
|
|
All the `Modal.method`s will return a reference, and then we can update and close the modal dialog by the reference.
|
|
|
|
```jsx
|
|
const modal = Modal.info();
|
|
|
|
modal.update({
|
|
title: 'Updated title',
|
|
content: 'Updated content',
|
|
});
|
|
|
|
modal.destroy();
|
|
```
|
|
|
|
- `Modal.destroyAll`
|
|
|
|
`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)
|
|
|
|
```jsx
|
|
import { browserHistory } from 'react-router';
|
|
|
|
// router change
|
|
browserHistory.listen(() => {
|
|
Modal.destroyAll();
|
|
});
|
|
```
|
|
|
|
### Modal.useModal()
|
|
|
|
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()>).
|
|
|
|
```jsx
|
|
const [modal, contextHolder] = Modal.useModal();
|
|
|
|
React.useEffect(() => {
|
|
modal.confirm({
|
|
// ...
|
|
});
|
|
}, []);
|
|
|
|
return <div>{contextHolder}</div>;
|
|
```
|
|
|
|
### Modal.config() `4.5.0+`
|
|
|
|
Like `message.config()`, `Modal.config()` could set `Modal.confirm` props globally (such as `prefixCls`), and it will affect `Modal.confirm|success|info|error|warning` **static methods only**.
|
|
|
|
```jsx
|
|
Modal.config({
|
|
rootPrefixCls: 'ant',
|
|
});
|
|
```
|
|
|
|
## FAQ
|
|
|
|
### 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:
|
|
|
|
```tsx
|
|
const [modal, contextHolder] = Modal.useModal();
|
|
|
|
// then call modal.confirm instead of Modal.confirm
|
|
|
|
return (
|
|
<Context1.Provider value="Ant">
|
|
{/* contextHolder is in Context1 which mean modal will not get context of Context1 */}
|
|
{contextHolder}
|
|
<Context2.Provider value="Design">
|
|
{/* contextHolder is out of Context2 which mean modal will not get context of Context2 */}
|
|
</Context2.Provider>
|
|
</Context1.Provider>
|
|
);
|
|
```
|
|
|
|
**Note:** You must insert `contextHolder` into your children with hooks. You can use origin method if you do not need context connection.
