## zh-CN
最基本的用法,展示了 `dataSource`、`targetKeys`、每行的渲染函数 `render` 以及回调函数 `onChange` `onSelectChange` `onScroll` 的用法。
## en-US
The most basic usage of `Transfer` involves providing the source data and target keys arrays, plus the rendering and some callback functions.
````jsx
import { Transfer, Switch } from 'antd';
const mockData = [];
for (let i = 0; i < 20; i++) {
mockData.push({
key: i.toString(),
title: `content${i + 1}`,
description: `description of content${i + 1}`,
disabled: i % 3 < 1,
});
}
const oriTargetKeys = mockData
.filter(item => +item.key % 3 > 1)
.map(item => item.key);
class App extends React.Component {
state = {
targetKeys: oriTargetKeys,
selectedKeys: [],
disabled: false,
}
handleChange = (nextTargetKeys, direction, moveKeys) => {
this.setState({ targetKeys: nextTargetKeys });
console.log('targetKeys: ', nextTargetKeys);
console.log('direction: ', direction);
console.log('moveKeys: ', moveKeys);
}
handleSelectChange = (sourceSelectedKeys, targetSelectedKeys) => {
this.setState({ selectedKeys: [...sourceSelectedKeys, ...targetSelectedKeys] });
console.log('sourceSelectedKeys: ', sourceSelectedKeys);
console.log('targetSelectedKeys: ', targetSelectedKeys);
}
handleScroll = (direction, e) => {
console.log('direction:', direction);
console.log('target:', e.target);
}
handleDisable = (disabled) => {
this.setState({ disabled });
};
render() {
const { targetKeys, selectedKeys, disabled } = this.state;
return (
<div>
<Transfer
dataSource={mockData}
titles={['Source', 'Target']}
targetKeys={targetKeys}
selectedKeys={selectedKeys}
onChange={this.handleChange}
onSelectChange={this.handleSelectChange}
onScroll={this.handleScroll}
render={item => item.title}
disabled={disabled}
/>
<Switch unCheckedChildren="disabled" checkedChildren="disabled" checked={disabled} onChange={this.handleDisable} />
</div>
);
}
}
ReactDOM.render(<App />, mountNode);
