Components 数据录入 Cascader 级联选择 https://gw.alipayobjects.com/zos/alicdn/UdS8y8xyZ/Cascader.svg

级联选择框。

何时使用

  • 需要从一组相关联的数据集合进行选择,例如省市区,公司层级,事物分类等。
  • 从一个较大的数据集合中进行选择时,用多级分类进行分隔,方便选择。
  • 比起 Select 组件,可以在同一个浮层中完成选择,有较好的体验。

代码演示

基本 默认值 可以自定义显示 移入展开 禁用选项 选择即改变 多选 自定义回填方式 大小 自定义已选项 搜索 动态加载选项 自定义字段名 自定义图标 扩展菜单 弹出位置 自定义状态 _InternalPanelDoNotUseOrYouWillBeFired

API

<Cascader options={options} onChange={onChange} />
参数 说明 类型 默认值 版本
allowClear 是否支持清除 boolean true
autoFocus 自动获取焦点 boolean false
bordered 是否有边框 boolean true
clearIcon 自定义的选择框清空图标 ReactNode -
changeOnSelect (单选时生效)当此项为 true 时,点选每级菜单选项值都会发生变化,具体见上面的演示 boolean false
className 自定义类名 string -
defaultValue 默认的选中项 string[] | number[] []
disabled 禁用 boolean false
displayRender 选择后展示的渲染函数 (label, selectedOptions) => ReactNode label => label.join(/) multiple: 4.18.0
popupClassName 自定义浮层类名 string - 4.23.0
dropdownRender 自定义下拉框内容 (menus: ReactNode) => ReactNode - 4.4.0
expandIcon 自定义次级菜单展开图标 ReactNode - 4.4.0
expandTrigger 次级菜单的展开方式,可选 'click' 和 'hover' string click
fieldNames 自定义 options 中 label value children 的字段 object { label: label, value: value, children: children }
getPopupContainer 菜单渲染父节点。默认渲染到 body 上,如果你遇到菜单滚动定位问题,试试修改为滚动的区域,并相对其定位。示例 function(triggerNode) () => document.body
loadData 用于动态加载选项,无法与 showSearch 一起使用 (selectedOptions) => void -
maxTagCount 最多显示多少个 tag响应式模式会对性能产生损耗 number | responsive - 4.17.0
maxTagPlaceholder 隐藏 tag 时显示的内容 ReactNode | function(omittedValues) - 4.17.0
notFoundContent 当下拉列表为空时显示的内容 string Not Found
open 控制浮层显隐 boolean - 4.17.0
options 可选项数据源 Option[] -
placeholder 输入框占位文本 string 请选择
placement 浮层预设位置 bottomLeft bottomRight topLeft topRight bottomLeft 4.17.0
showSearch 在选择框中显示搜索框 boolean | Object false
size 输入框大小 large | middle | small -
status 设置校验状态 'error' | 'warning' - 4.19.0
style 自定义样式 CSSProperties -
suffixIcon 自定义的选择框后缀图标 ReactNode -
value 指定选中项 string[] | number[] -
onChange 选择完成后的回调 (value, selectedOptions) => void -
onDropdownVisibleChange 显示/隐藏浮层的回调 (value) => void - 4.17.0
multiple 支持多选节点 boolean - 4.17.0
showCheckedStrategy 定义选中项回填的方式。Cascader.SHOW_CHILD: 只显示选中的子节点。Cascader.SHOW_PARENT: 只显示父节点(当父节点下所有子节点都选中时)。 Cascader.SHOW_PARENT | Cascader.SHOW_CHILD Cascader.SHOW_PARENT 4.20.0
removeIcon 自定义的多选框清除图标 ReactNode -
searchValue 设置搜索的值,需要与 showSearch 配合使用 string - 4.17.0
onSearch 监听搜索,返回输入的值 (search: string) => void - 4.17.0
dropdownMenuColumnStyle 下拉菜单列的样式 CSSProperties -

showSearch

showSearch 为对象时,其中的字段:

参数 说明 类型 默认值 版本
filter 接收 inputValue path 两个参数,当 path 符合筛选条件时,应返回 true反之则返回 false function(inputValue, path): boolean -
limit 搜索结果展示数量 number | false 50
matchInputWidth 搜索结果列表是否与输入框同宽(效果 boolean true
render 用于渲染 filter 后的选项 function(inputValue, path): ReactNode -
sort 用于排序 filter 后的选项 function(a, b, inputValue) -

Option

interface Option {
  value: string | number;
  label?: React.ReactNode;
  disabled?: boolean;
  children?: Option[];
  // 标记是否为叶子节点,设置了 `loadData` 时有效
  // 设为 `false` 时会强制标记为父节点,即使当前节点没有 children也会显示展开图标
  isLeaf?: boolean;
}

方法

名称 描述 版本
blur() 移除焦点
focus() 获取焦点
