|

## zh-CN
|
|
|
|
通过 `notification.useNotification` 创建支持读取 context 的 `contextHolder`。
|
|
|
|
## en-US
|
|
|
|
Use `notification.useNotification` to get `contextHolder` with context accessible issue.
|
|
|
|
```jsx
|
|
import { Button, notification, Divider } 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}
|
|
<Button type="primary" onClick={() => openNotification('topLeft')}>
|
|
<RadiusUpleftOutlined />
|
|
topLeft
|
|
</Button>
|
|
<Button type="primary" onClick={() => openNotification('topRight')}>
|
|
<RadiusUprightOutlined />
|
|
topRight
|
|
</Button>
|
|
<Divider />
|
|
<Button type="primary" onClick={() => openNotification('bottomLeft')}>
|
|
<RadiusBottomleftOutlined />
|
|
bottomLeft
|
|
</Button>
|
|
<Button type="primary" onClick={() => openNotification('bottomRight')}>
|
|
<RadiusBottomrightOutlined />
|
|
bottomRight
|
|
</Button>
|
|
</Context.Provider>
|

);
|

};

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