全局展示通知提醒信息。
## 何时使用
在系统四个角显示通知提醒信息。经常用于以下情况:
2015-08-05 21:18:34 +08:00
- 较为复杂的通知内容。
- 带有交互的通知,给出用户下一步的行动点。
- 系统主动推送。

## FAQ
2020-11-12 11:17:34 +08:00
### 为什么 notification 不能获取 context、redux 的内容和 ConfigProvider 的 `locale/prefixCls` 配置?
直接调用 notification 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 `notification.useNotification` 方法会返回 `api` 实体以及 `contextHolder` 节点。将其插入到你需要获取 context 位置即可:
```tsx
const [api, contextHolder] = notification.useNotification();
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。
### 静态方法如何设置 prefixCls
你可以通过 [`ConfigProvider.config`](</components/config-provider/#ConfigProvider.config()-4.13.0+>) 进行设置。
