## zh-CN

通过 `oneWay` 将 Transfer 转为单向样式。

## en-US

Use `oneWay` to makes Transfer to one way style.

```tsx
import { Switch, Transfer } from 'antd';
import type { TransferDirection } from 'antd/es/transfer';
import React, { useState } from 'react';

interface RecordType {
  key: string;
  title: string;
  description: string;
  disabled: boolean;
}

const mockData: RecordType[] = Array.from({ length: 20 }).map((_, i) => ({
  key: i.toString(),
  title: `content${i + 1}`,
  description: `description of content${i + 1}`,
  disabled: i % 3 < 1,
}));

const oriTargetKeys = mockData.filter(item => Number(item.key) % 3 > 1).map(item => item.key);

const App: React.FC = () => {
  const [targetKeys, setTargetKeys] = useState<string[]>(oriTargetKeys);
  const [selectedKeys, setSelectedKeys] = useState<string[]>([]);
  const [disabled, setDisabled] = useState(false);

  const handleChange = (
    newTargetKeys: string[],
    direction: TransferDirection,
    moveKeys: string[],
  ) => {
    setTargetKeys(newTargetKeys);

    console.log('targetKeys: ', newTargetKeys);
    console.log('direction: ', direction);
    console.log('moveKeys: ', moveKeys);
  };

  const handleSelectChange = (sourceSelectedKeys: string[], targetSelectedKeys: string[]) => {
    setSelectedKeys([...sourceSelectedKeys, ...targetSelectedKeys]);

    console.log('sourceSelectedKeys: ', sourceSelectedKeys);
    console.log('targetSelectedKeys: ', targetSelectedKeys);
  };

  const handleScroll = (
    direction: TransferDirection,
    e: React.SyntheticEvent<HTMLUListElement, Event>,
  ) => {
    console.log('direction:', direction);
    console.log('target:', e.target);
  };

  const handleDisable = (checked: boolean) => {
    setDisabled(checked);
  };

  return (
    <>
      <Transfer
        dataSource={mockData}
        titles={['Source', 'Target']}
        targetKeys={targetKeys}
        selectedKeys={selectedKeys}
        onChange={handleChange}
        onSelectChange={handleSelectChange}
        onScroll={handleScroll}
        render={item => item.title}
        disabled={disabled}
        oneWay
        style={{ marginBottom: 16 }}
      />
      <Switch
        unCheckedChildren="disabled"
        checkedChildren="disabled"
        checked={disabled}
        onChange={handleDisable}
      />
    </>
  );
};

export default App;
```
