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
