## zh-CN
在 Ant Design 规范中,操作按钮建议放在抽屉的右上角,可以使用 `extra` 属性来实现。
## en-US
Extra actions should be placed at corner of drawer in Ant Design, you can using `extra` prop for that.
```tsx
import React, { useState } from 'react';
import { Drawer, Button, Space, Radio } from 'antd';
import { DrawerProps } from 'antd/es/drawer';
import { RadioChangeEvent } from 'antd/es/radio';
const App: React.FC = () => {
const [visible, setVisible] = useState(false);
const [placement, setPlacement] = useState<DrawerProps['placement']>('right');
const showDrawer = () => {
setVisible(true);
};
const onChange = (e: RadioChangeEvent) => {
setPlacement(e.target.value);
};
const onClose = () => {
setVisible(false);
};
return (
<>
<Space>
<Radio.Group value={placement} onChange={onChange}>
<Radio value="top">top</Radio>
<Radio value="right">right</Radio>
<Radio value="bottom">bottom</Radio>
<Radio value="left">left</Radio>
</Radio.Group>
<Button type="primary" onClick={showDrawer}>
Open
</Button>
</Space>
<Drawer
title="Drawer with extra actions"
placement={placement}
width={500}
onClose={onClose}
visible={visible}
extra={
<Space>
<Button onClick={onClose}>Cancel</Button>
<Button type="primary" onClick={onClose}>
OK
</Button>
</Space>
}
>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
</Drawer>
</>
);
};
ReactDOM.render(<App />, mountNode);
```
