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

最简单的用法,4.5 秒后自动关闭。

expand codeexpand code
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!');
    },
  });
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

通知提醒框左侧有图标。

expand codeexpand code
import { Button, notification, Space } from 'antd';

const openNotificationWithIcon = type => {
  notification[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.',
  });
};

ReactDOM.render(
  <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>,
  mountNode,
);

图标可以被自定义。

expand codeexpand code
import { Button, notification } from 'antd';
import { SmileOutlined } from '@ant-design/icons';

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.',
    icon: <SmileOutlined style={{ color: '#108ee9' }} />,
  });
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

使用 style 和 className 来定义样式。

expand codeexpand code
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.',
    className: 'custom-class',
    style: {
      width: 600,
    },
  });
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

通过 notification.useNotification 创建支持读取 context 的 contextHolder

expand codeexpand code
import { Button, notification, Divider, Space } from 'antd';
import {
  RadiusUpleftOutlined,
  RadiusUprightOutlined,
  RadiusBottomleftOutlined,
  RadiusBottomrightOutlined,
} from '@ant-design/icons';

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

const Demo = () => {
  const [api, contextHolder] = notification.useNotification();

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

  return (
    <Context.Provider value={{ name: 'Ant Design' }}>
      {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>
  );
};

ReactDOM.render(<Demo />, mountNode);

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。

expand codeexpand code
import { Button, notification } from 'antd';

const openNotification = () => {
  const args = {
    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,
  };
  notification.open(args);
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

自定义关闭按钮的样式和文字。

expand codeexpand code
import { Button, notification } from 'antd';

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

const openNotification = () => {
  const key = `open${Date.now()}`;
  const btn = (
    <Button type="primary" size="small" onClick={() => notification.close(key)}>
      Confirm
    </Button>
  );
  notification.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,
  });
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

通知从右上角、右下角、左下角、左上角弹出。

expand codeexpand code
import { Button, notification, Divider, Space } from 'antd';
import {
  RadiusUpleftOutlined,
  RadiusUprightOutlined,
  RadiusBottomleftOutlined,
  RadiusBottomrightOutlined,
} from '@ant-design/icons';

const openNotification = placement => {
  notification.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,
  });
};

ReactDOM.render(
  <div>
    <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>
  </div>,
  mountNode,
);

可以通过唯一的 key 来更新内容。

expand codeexpand code
import { Button, notification } from 'antd';

const key = 'updatable';

const openNotification = () => {
  notification.open({
    key,
    message: 'Notification Title',
    description: 'description.',
  });
  setTimeout(() => {
    notification.open({
      key,
      message: 'New Title',
      description: 'New description.',
    });
  }, 1000);
};

ReactDOM.render(
  <Button type="primary" onClick={openNotification}>
    Open the notification box
  </Button>,
  mountNode,
);

还提供了一个全局配置方法,在调用前提前配置,全局一次生效。

  • 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,
});

bottom消息从底部弹出时,距离底部的位置,单位像素number24

FAQ#

为什么 notification 不能获取 context、redux 的内容?#

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。
