Notification通知提醒框

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：

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。

代码演示

通过 notification.useNotification 创建支持读取 context 的 contextHolder。请注意，我们推荐通过顶层注册的方式代替 message 静态方法，因为静态方法无法消费上下文，因而 ConfigProvider 的数据也不会生效。

TypeScript
JavaScript
import React, { useMemo } from 'react';
import {
  RadiusBottomleftOutlined,
  RadiusBottomrightOutlined,
  RadiusUpleftOutlined,
  RadiusUprightOutlined,
} from '@ant-design/icons';
import { Button, Divider, notification, Space } from 'antd';
import type { NotificationPlacement } from 'antd/es/notification/interface';

const Context = React.createContext({ name: 'Default' });

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = (placement: NotificationPlacement) => {
    api.info({
      message: `Notification ${placement}`,
      description: <Context.Consumer>{({ name }) => `Hello, ${name}!`}</Context.Consumer>,
      placement,
    });
  };

  const contextValue = useMemo(() => ({ name: 'Ant Design' }), []);

  return (
    <Context.Provider value={contextValue}>
      {contextHolder}
      <Space>
        <Button type="primary" onClick={() => openNotification('topLeft')}>
          <RadiusUpleftOutlined />
          topLeft
        </Button>
        <Button type="primary" onClick={() => openNotification('topRight')}>
          <RadiusUprightOutlined />
          topRight
        </Button>
      </Space>
      <Divider />
      <Space>
        <Button type="primary" onClick={() => openNotification('bottomLeft')}>
          <RadiusBottomleftOutlined />
          bottomLeft
        </Button>
        <Button type="primary" onClick={() => openNotification('bottomRight')}>
          <RadiusBottomrightOutlined />
          bottomRight
        </Button>
      </Space>
    </Context.Provider>
  );
};

export default App;

自动关闭的延时

自定义通知框自动关闭的延时，默认 4.5s，取消自动关闭只要将该值设为 0 即可。

TypeScript
JavaScript
import React from 'react';
import { Button, notification } from 'antd';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = () => {
    api.open({
      message: 'Notification Title',
      description:
        'I will never close automatically. This is a purposely very very long description that has many many characters and words.',
      duration: 0,
    });
  };

  return (
    <>
      {contextHolder}
      <Button type="primary" onClick={openNotification}>
        Open the notification box
      </Button>
    </>
  );
};

export default App;

自定义按钮

自定义关闭按钮的样式和文字。

TypeScript
JavaScript
import React from 'react';
import { Button, notification, Space } from 'antd';

const close = () => {
  console.log(
    'Notification was closed. Either the close button was clicked or duration time elapsed.',
  );
};

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = () => {
    const key = `open${Date.now()}`;
    const btn = (
      <Space>
        <Button type="link" size="small" onClick={() => api.destroy()}>
          Destroy All
        </Button>
        <Button type="primary" size="small" onClick={() => api.destroy(key)}>
          Confirm
        </Button>
      </Space>
    );
    api.open({
      message: 'Notification Title',
      description:
        'A function will be be called after the notification is closed (automatically after the "duration" time of manually).',
      btn,
      key,
      onClose: close,
    });
  };

  return (
    <>
      {contextHolder}
      <Button type="primary" onClick={openNotification}>
        Open the notification box
      </Button>
    </>
  );
};

export default App;

位置

使用 placement 可以配置通知从右上角、右下角、左下角、左上角弹出。

TypeScript
JavaScript
import React from 'react';
import {
  BorderBottomOutlined,
  BorderTopOutlined,
  RadiusBottomleftOutlined,
  RadiusBottomrightOutlined,
  RadiusUpleftOutlined,
  RadiusUprightOutlined,
} from '@ant-design/icons';
import { Button, Divider, notification, Space } from 'antd';
import type { NotificationPlacement } from 'antd/es/notification/interface';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = (placement: NotificationPlacement) => {
    api.info({
      message: `Notification ${placement}`,
      description:
        'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
      placement,
    });
  };

  return (
    <>
      {contextHolder}
      <Space>
        <Button type="primary" onClick={() => openNotification('top')} icon={<BorderTopOutlined />}>
          top
        </Button>
        <Button
          type="primary"
          onClick={() => openNotification('bottom')}
          icon={<BorderBottomOutlined />}
        >
          bottom
        </Button>
      </Space>
      <Divider />
      <Space>
        <Button
          type="primary"
          onClick={() => openNotification('topLeft')}
          icon={<RadiusUpleftOutlined />}
        >
          topLeft
        </Button>
        <Button
          type="primary"
          onClick={() => openNotification('topRight')}
          icon={<RadiusUprightOutlined />}
        >
          topRight
        </Button>
      </Space>
      <Divider />
      <Space>
        <Button
          type="primary"
          onClick={() => openNotification('bottomLeft')}
          icon={<RadiusBottomleftOutlined />}
        >
          bottomLeft
        </Button>
        <Button
          type="primary"
          onClick={() => openNotification('bottomRight')}
          icon={<RadiusBottomrightOutlined />}
        >
          bottomRight
        </Button>
      </Space>
    </>
  );
};

export default App;

更新消息内容

可以通过唯一的 key 来更新内容。

TypeScript
JavaScript
import React from 'react';
import { Button, notification } from 'antd';

const key = 'updatable';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();
  const openNotification = () => {
    api.open({
      key,
      message: 'Notification Title',
      description: 'description.',
    });

    setTimeout(() => {
      api.open({
        key,
        message: 'New Title',
        description: 'New description.',
      });
    }, 1000);
  };

  return (
    <>
      {contextHolder}
      <Button type="primary" onClick={openNotification}>
        Open the notification box
      </Button>
    </>
  );
};

export default App;

基本

最简单的用法，4.5 秒后自动关闭。

TypeScript
JavaScript
import React from 'react';
import { Button, notification } from 'antd';

const openNotification = () => {
  notification.open({
    message: 'Notification Title',
    description:
      'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
    onClick: () => {
      console.log('Notification Clicked!');
    },
  });
};
const App: React.FC = () => (
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>
);

export default App;

带有图标的通知提醒框

通知提醒框左侧有图标。

TypeScript
JavaScript
import React from 'react';
import { Button, notification, Space } from 'antd';

type NotificationType = 'success' | 'info' | 'warning' | 'error';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotificationWithIcon = (type: NotificationType) => {
    api[type]({
      message: 'Notification Title',
      description:
        'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
    });
  };

  return (
    <>
      {contextHolder}
      <Space>
        <Button onClick={() => openNotificationWithIcon('success')}>Success</Button>
        <Button onClick={() => openNotificationWithIcon('info')}>Info</Button>
        <Button onClick={() => openNotificationWithIcon('warning')}>Warning</Button>
        <Button onClick={() => openNotificationWithIcon('error')}>Error</Button>
      </Space>
    </>
  );
};

export default App;

自定义图标

图标可以被自定义。

TypeScript
JavaScript
import React from 'react';
import { SmileOutlined } from '@ant-design/icons';
import { Button, notification } from 'antd';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = () => {
    api.open({
      message: 'Notification Title',
      description:
        'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
      icon: <SmileOutlined style={{ color: '#108ee9' }} />,
    });
  };

  return (
    <>
      {contextHolder}
      <Button type="primary" onClick={openNotification}>
        Open the notification box
      </Button>
    </>
  );
};

export default App;

自定义样式

使用 style 和 className 来定义样式。

TypeScript
JavaScript
import React from 'react';
import { Button, notification } from 'antd';

const App: React.FC = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = () => {
    api.open({
      message: 'Notification Title',
      description:
        'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
      className: 'custom-class',
      style: {
        width: 600,
      },
    });
  };

  return (
    <>
      {contextHolder}
      <Button type="primary" onClick={openNotification}>
        Open the notification box
      </Button>
    </>
  );
};
export default App;

notification.config(options)

当你使用 ConfigProvider 进行全局化配置时，系统会默认自动开启 RTL 模式。(4.3.0+)
当你想单独使用，可通过如下设置开启 RTL 模式。

notification.config({
  placement: 'bottomRight',
  bottom: 50,
  duration: 3,
  rtl: true,
});

FAQ

为什么 notification 不能获取 context、redux 的内容和 ConfigProvider 的 `locale/prefixCls/theme` 等配置？

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：

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。

可通过 App 包裹组件简化 useNotification 等方法需要手动植入 contextHolder 的问题。

静态方法如何设置 prefixCls ？

你可以通过 ConfigProvider.config 进行设置。
