Components 树选择 数据录入 TreeSelect

树型选择控件。

何时使用

类似 Select 的选择控件,可选择的数据结构是一个树形结构时,可以使用 TreeSelect例如公司层级、学科系统、分类目录等等。

API

Tree props

参数 说明 类型 默认值
allowClear 显示清除按钮 boolean false
autoClearSearchValue 当多选模式下值被选择,自动清空搜索框 boolean true
defaultValue 指定默认选中的条目 string/string[] -
disabled 是否禁用 boolean false
dropdownClassName 下拉菜单的 className 属性 string -
dropdownMatchSelectWidth 下拉菜单和选择器同宽。默认将设置 min-width boolean true
dropdownStyle 下拉菜单的样式 object -
filterTreeNode 是否根据输入项进行筛选,默认用 treeNodeFilterProp 的值作为要筛选的 TreeNode 的属性值 boolean|Function(inputValue: string, treeNode: TreeNode) (函数需要返回bool值) Function
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
labelInValue 是否把每个选项的 label 包装到 value 中,会把 value 类型从 string 变为 {value: string, label: ReactNode, halfChecked(treeCheckStrictly 时有效): string[] } 的格式 boolean false
loadData 异步加载数据 function(node) -
maxTagCount 最多显示多少个 tag number -
maxTagPlaceholder 隐藏 tag 时显示的内容 ReactNode/function(omittedValues) -
multiple 支持多选(当设置 treeCheckable 时自动变为true boolean false
placeholder 选择框默认文字 string -
searchPlaceholder 搜索框默认文字 string -
searchValue 搜索框的值,可以通过 onSearch 获取用户输入 string -
treeIcon 是否展示 TreeNode title 前的图标,没有默认样式,如设置为 true需要自行定义图标相关样式 boolean false
showCheckedStrategy 定义选中项回填的方式。TreeSelect.SHOW_ALL: 显示所有选中节点(包括父节点). TreeSelect.SHOW_PARENT: 只显示父节点(当父节点下所有子节点都选中时). 默认只显示子节点. enum{TreeSelect.SHOW_ALL, TreeSelect.SHOW_PARENT, TreeSelect.SHOW_CHILD } TreeSelect.SHOW_CHILD
showSearch 是否支持搜索框 boolean 单选:false | 多选:true
size 选择框大小,可选 large small string 'default'
suffixIcon 自定义的选择框后缀图标 ReactNode -
treeCheckable 显示 checkbox boolean false
treeCheckStrictly checkable 状态下节点选择完全受控(父子节点选中状态不再关联),会使得 labelInValue 强制为 true boolean false
treeData treeNodes 数据,如果设置则不需要手动构造 TreeNode 节点value 在整个树范围内唯一) array<{value, title, children, [disabled, disableCheckbox, selectable]}> []
treeDataSimpleMode 使用简单格式的 treeData具体设置参考可设置的类型 (此时 treeData 应变为这样的数据结构: [{id:1, pId:0, value:'1', title:"test1",...},...], pId 是父节点的 id) false|object<{ id: string, pId: string, rootPId: string }> false
treeDefaultExpandAll 默认展开所有树节点 boolean false
treeDefaultExpandedKeys 默认展开的树节点 string[] -
treeExpandedKeys 设置展开的树节点 string[] -
treeNodeFilterProp 输入项过滤对应的 treeNode 属性 string 'value'
treeNodeLabelProp 作为显示的 prop 设置 string 'title'
value 指定当前选中的条目 string/string[] -
onChange 选中树节点时调用此函数 function(value, label, extra) -
onSearch 文本框值变化时回调 function(value: string) -
onSelect 被选中时调用 function(value, node, extra) -
onTreeExpand 展示节点时调用 function(expandedKeys) -

Tree 方法

名称 描述
blur() 移除焦点
focus() 获取焦点

TreeNode props

建议使用 treeData 来代替 TreeNode免去手工构造麻烦

参数 说明 类型 默认值
selectable 是否可选 boolean true
disableCheckbox 禁掉 checkbox boolean false
disabled 是否禁用 boolean false
isLeaf 是否是叶子节点 boolean false
key 此项必须设置(其值在整个树范围内唯一) string -
title 树节点显示的内容 string|ReactNode '---'
value 默认根据此属性值进行筛选(其值在整个树范围内唯一) string -

FAQ

onChange 时如何获得父节点信息?

从性能角度考虑,我们默认不透出父节点信息。你可以这样获得:https://codesandbox.io/s/wk080nn81k
