Transfer穿梭框

双栏穿梭选择框。

何时使用#

  • 需要在多个可选项中进行多选时。

  • 比起 Select 和 TreeSelect，穿梭框占据更大的空间，可以展示可选项的更多信息。

穿梭选择框用直观的方式在两栏中移动元素，完成选择行为。

选择一个或以上的选项后，点击对应的方向键，可以把选中的选项移动到另一栏。其中，左边一栏为 source，右边一栏为 target，API 的设计也反映了这两个概念。

基本用法

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。

import { Transfer, Switch } from 'antd';

const mockData = [];

Render Props#

Transfer 支持接收 children 自定义渲染列表，并返回以下参数：

参数说明类型版本
direction渲染列表的方向left | right
disabled是否禁用列表boolean
filteredItems过滤后的数据TransferItem[]
onItemSelect勾选条目(key: string, selected: boolean)
onItemSelectAll勾选一组条目(keys: string[], selected: boolean)
selectedKeys选中的条目string[]

参考示例#

<Transfer {...props}>{listProps => <YourComponent {...listProps} />}</Transfer>

注意#

按照 React 的规范，所有的组件数组必须绑定 key。在 Transfer 中，dataSource里的数据值需要指定 key 值。对于 dataSource 默认将每列数据的 key 属性作为唯一的标识。

如果你的数据没有这个属性，务必使用 rowKey 来指定数据列的主键。

// 比如你的数据主键是 uid
return <Transfer rowKey={record => record.uid} />;

FAQ#

怎样让 Transfer 穿梭框列表支持异步数据加载#

为了保持页码同步，在勾选时可以不移除选项而以禁用代替：https://codesandbox.io/s/93xeb
