点击菜单项后会触发事件，用户可以通过相应的菜单项 key 进行不同的操作。

## en-US

An event will be triggered when you click menu items, in which you can make different operations according to item's key.

```tsx
import { DownOutlined } from '@ant-design/icons';
import type { MenuProps } from 'antd';
import { Dropdown, message, Space } from 'antd';
import React from 'react';

const onClick: MenuProps['onClick'] = ({ key }) => {
  message.info(`Click on item ${key}`);
};

const items: MenuProps['items'] = [
  {
    label: '1st menu item',
    key: '1',
  },
  {
    label: '2nd menu item',
    key: '2',
  },
  {
    label: '3rd menu item',
    key: '3',
  },
];

const App: React.FC = () => (
  <Dropdown menu={{ items, onClick }}>
    <a onClick={e => e.preventDefault()}>
      <Space>
        Hover me, Click menu item
        <DownOutlined />
      </Space>
    </a>
  </Dropdown>
);

export default App;
```
