模态对话框。
## 何时使用
需要用户处理事务,又不希望跳转页面以致打断工作流程时,可以使用 `Modal` 在当前页面正中打开一个浮层,承载相应的操作。
2019-01-09 23:37:38 +08:00
另外当需要一个简洁的确认框询问用户时,可以使用 `Modal.confirm()` 等语法糖方法。

以上函数调用后,会返回一个引用,可以通过该引用更新和关闭弹窗。
```jsx
const modal = Modal.info();
modal.update({
title: '修改的标题',
2018-08-25 21:58:40 +08:00
content: '修改的内容',
});
modal.destroy();
```
- `Modal.destroyAll`
使用 `Modal.destroyAll()` 可以销毁弹出的确认窗(即上述的 Modal.info、Modal.success、Modal.error、Modal.warning、Modal.confirm。通常用于路由监听当中处理路由前进、后退不能销毁确认对话框的问题而不用各处去使用实例的返回值进行关闭modal.destroy() 适用于主动关闭,而不是路由这样被动关闭)
```jsx
import { browserHistory } from 'react-router';
// router change
browserHistory.listen(() => {
Modal.destroyAll();
});
```
### Modal.useModal()
当你需要使用 Context 时,可以通过 `Modal.useModal` 创建一个 `contextHolder` 插入子节点中。通过 hooks 创建的临时 Modal 将会得到 `contextHolder` 所在位置的所有上下文。创建的 `modal` 对象拥有与 [`Modal.method`](<#Modal.method()>) 相同的创建通知方法。
```jsx
const [modal, contextHolder] = Modal.useModal();
React.useEffect(() => {
modal.confirm({
// ...
});
}, []);
return <div>{contextHolder}</div>;
```
## FAQ
### 为什么 Modal 方法不能获取 context、redux 的内容?
直接调用 Modal 方法antd 会通过 `ReactDOM.render` 动态创建新的 React 实体。其 context 与当前代码所在 context 并不相同,因而无法获取 context 信息。
当你需要 context 信息(例如 ConfigProvider 配置的内容)时,可以通过 `Modal.useModal` 方法会返回 `modal` 实体以及 `contextHolder` 节点。将其插入到你需要获取 context 位置即可:
```tsx
const [modal, contextHolder] = Modal.useModal();
return (
<Context1.Provider value="Ant">
{/* contextHolder 在 Context1 内,它可以获得 Context1 的 context */}
{contextHolder}
<Context2.Provider value="Design">
{/* contextHolder 在 Context2 外,因而不会获得 Context2 的 context */}
</Context2.Provider>
</Context1.Provider>
);
```
**异同:**通过 hooks 创建的 `contextHolder` 必须插入到子元素节点中才会生效,当你不需要上下文信息时请直接调用。
