--- title: InputTree 树形选择框 description: type: 0 group: null menuName: InpputTree 树形选择框 icon: order: 59 --- ## 基本使用 配置的`options`中,可以通过`children`字段进行嵌套展示,实现树形选择器 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "options": [ { "label": "Folder A", "value": 1, "children": [ { "label": "file A", "value": 2 }, { "label": "Folder B", "value": 3, "children": [ { "label": "file b1", "value": 3.1 }, { "label": "file b2", "value": 3.2 } ] } ] }, { "label": "file C", "value": 4 }, { "label": "file D", "value": 5 } ] } ] } ``` ## 选择器样式 配置`"type": "tree-select"`可以实现选择器样式 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "tree-select", "name": "tree", "label": "Tree", "options": [ { "label": "Folder A", "value": 1, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "file C", "value": 4 }, { "label": "file D", "value": 5 } ] } ] } ``` ## 是否显示展开线 > 1.1.6 版本 通过 `showOutline` 来控制是否显示展开线。 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "showOutline": true, "options": [ { "label": "Folder A", "value": 1, "children": [ { "label": "file A", "value": 2 }, { "label": "Folder B", "value": 3, "children": [ { "label": "file b1", "value": 3.1 }, { "label": "file b2", "value": 3.2 } ] } ] }, { "label": "file C", "value": 4 }, { "label": "file D", "value": 5 } ] } ] } ``` ## 选中父节点是否自动选中子节点 默认选中父节点会自动选中子节点,可以设置`"cascade": true`,不自动选中子节点 ```schema: scope="body" { "type": "form", "debug": true, "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree1", "label": "默认自动选中子节点", "multiple": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] }, { "type": "divider" }, { "type": "input-tree", "name": "tree2", "label": "不自动选中子节点", "multiple": true, "cascade": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] } ] } ``` ## 选中父节点,值是否包含子节点 默认选中父节点,是不会带上子节点的值,想要自动带上子节点的值,那么配置`"withChildren": true` ```schema: scope="body" { "type": "form", "debug": true, "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree1", "label": "默认不自动带上子节点的值", "multiple": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] }, { "type": "divider" }, { "type": "input-tree", "name": "tree2", "label": "自动带上子节点的值", "multiple": true, "withChildren": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] } ] } ``` 也可以设置`onlyChildren`,实现只包含子节点的值 ```schema: scope="body" { "type": "form", "debug": true, "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree1", "label": "默认不自动带上子节点的值", "multiple": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] }, { "type": "divider" }, { "type": "input-tree", "name": "tree2", "label": "只包含子节点的值", "multiple": true, "onlyChildren": true, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] } ] } ``` ## 默认展开 默认是展开所有子节点的,如果不想默认展开,则配置`"initiallyOpen": false` ```schema: scope="body" { "type": "form", "debug": true, "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree1", "label": "默认不自动带上子节点的值", "initiallyOpen": false, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2" }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] } ] } ``` 如果层级较多,也可以配置`unfoldedLevel`指定展开的层级数。 下例中设置`"unfoldedLevel": 1`,默认展开第 1 层 ```schema: scope="body" { "type": "form", "debug": true, "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree1", "label": "默认不自动带上子节点的值", "initiallyOpen": false, "unfoldedLevel": 1, "options": [ { "label": "A", "value": "a" }, { "label": "B", "value": "b", "children": [ { "label": "B-1", "value": "b-1" }, { "label": "B-2", "value": "b-2", "children": [ { "label": "B-2-1", "value": "b-2-1" }, { "label": "B-2-2", "value": "b-2-2" }, { "label": "B-2-3", "value": "b-2-3" } ] }, { "label": "B-3", "value": "b-3" } ] }, { "label": "C", "value": "c" } ] } ] } ``` ## 可编辑 配置 `creatable`、`removable` 和 `editable` 可以实现树可编辑。 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "creatable": true, "removable": true, "editable": true, "options": [ { "label": "Folder A", "value": 1, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "file C", "value": 4 }, { "label": "file D", "value": 5 } ] } ] } ``` ## 控制哪些项可编辑 配置 `creatable`、`removable` 和 `editable` 可以实现树可编辑,同时如果需要关闭部分节点的编辑权限,可以在节点上配置`creatable`、`removable` 和 `editable`。 `rootCreatable` 可以用来关闭顶层是否可以创建。如果想要控制顶层可编辑,请配置 `hideRoot`,用节点来控制。 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "creatable": true, "removable": true, "editable": true, "rootCreatable": false, "options": [ { "label": "Folder A", "value": 1, "creatable": false, "removable": false, "editable": false, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "file C", "value": 4, "removable": false }, { "label": "file D", "value": 5, "editable": false } ] } ] } ``` ## 控制添加/编辑的表单 配置 `addControls` 可以控制添加时需要填写哪些信息,同样还有 `editControls` 来配置编辑节点的表单 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "creatable": true, "addControls": [ { "label": "节点名称", "type": "input-text", "required": true, "name": "label" }, { "label": "节点值", "type": "input-text", "required": true, "name": "value" } ], "options": [ { "label": "Folder A", "value": 1, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "file C", "value": 4 }, { "label": "file D", "value": 5 } ] } ] } ``` ## 懒加载 > since 1.1.6 需要懒加载的选项请配置 `defer` 为 true,然后配置 `deferApi` 即可完成懒加载。如果不配置 `deferApi` 会使用 `source` 接口。 `deferApi` 中可以用到当前选项中的任何字段,比如以下这个例子是把 label 传给了 defer 接口 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "deferApi": "/api/mock2/form/deferOptions?label=${label}&waitSeconds=2", "options": [ { "label": "Folder A", "value": 1, "collapsed": true, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "这下面是懒加载的", "value": 4, "defer": true }, { "label": "file D", "value": 5 } ] } ] } ``` ## 节点路径模式 > since 1.2.4 配置`enableNodePath: true`后, 可以将`value`格式转换成节点路径模式,`pathSeparator`设置路径分隔符,建议将该属性的值和拼接符`delimeter`区分开。节点路径模式下,`value`中所有节点的父节点都会自动加载数据并回显。不同配置属性的节点路径模式`value`如下: ``` a / \ b d / c ---------------------------------------------- multiple joinValues extractValue value ---------------------------------------------- false true - 'a/b/c' false false false {label: 'A/B/C', value: 'a/b/c'} true true - 'a/b/c,a/d' true false true ['a/b/c', 'a/d'] true false true [{label: 'A/B/C', value: 'a/b/c'},{label: 'A/D', value: 'a/d'}] ``` ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "type": "input-tree", "name": "tree", "label": "Tree", "deferApi": "/api/mock2/form/deferOptions?label=${label}&waitSeconds=2", "value": "1/2,4/lazy-1/lazy-1-3,4/lazy-1/lazy-1-5", "enableNodePath": true, "pathSeparator": '/', "multiple": true, "options": [ { "label": "Folder A", "value": 1, "collapsed": true, "children": [ { "label": "file A", "value": 2 }, { "label": "file B", "value": 3 } ] }, { "label": "这下面是懒加载的", "value": 4, "defer": true }, { "label": "file D", "value": 5 } ] } ] } ``` ## 属性表 当做选择器表单项使用时,除了支持 [普通表单项属性表](./formitem#%E5%B1%9E%E6%80%A7%E8%A1%A8) 中的配置以外,还支持下面一些配置 | 属性名 | 类型 | 默认值 | 说明 | | ---------------------- | -------------------------------------------- | ---------------- | ------------------------------------------------------------------------------------------------------------------- | | options | `Array`或`Array` | | [选项组](./options#%E9%9D%99%E6%80%81%E9%80%89%E9%A1%B9%E7%BB%84-options) | | source | `string`或 [API](../../../../docs/types/api) | | [动态选项组](./options#%E5%8A%A8%E6%80%81%E9%80%89%E9%A1%B9%E7%BB%84-source) | | autoComplete | [API](../../../../docs/types/api) | | [自动提示补全](./options#%E8%87%AA%E5%8A%A8%E8%A1%A5%E5%85%A8-autocomplete) | | multiple | `boolean` | `false` | 是否多选 | | delimeter | `string` | `false` | [拼接符](./options#%E6%8B%BC%E6%8E%A5%E7%AC%A6-delimiter) | | labelField | `string` | `"label"` | [选项标签字段](./options#%E9%80%89%E9%A1%B9%E6%A0%87%E7%AD%BE%E5%AD%97%E6%AE%B5-labelfield) | | valueField | `string` | `"value"` | [选项值字段](./options#%E9%80%89%E9%A1%B9%E5%80%BC%E5%AD%97%E6%AE%B5-valuefield) | | iconField | `string` | `"icon"` | 图标值字段 | | joinValues | `boolean` | `true` | [拼接值](./options#%E6%8B%BC%E6%8E%A5%E5%80%BC-joinvalues) | | extractValue | `boolean` | `false` | [提取值](./options#%E6%8F%90%E5%8F%96%E5%A4%9A%E9%80%89%E5%80%BC-extractvalue) | | creatable | `boolean` | `false` | [新增选项](./options#%E5%89%8D%E7%AB%AF%E6%96%B0%E5%A2%9E-creatable) | | addControls | Array<[表单项](./formitem)> | | [自定义新增表单项](./options#%E8%87%AA%E5%AE%9A%E4%B9%89%E6%96%B0%E5%A2%9E%E8%A1%A8%E5%8D%95%E9%A1%B9-addcontrols) | | addApi | [API](../../../docs/types/api) | | [配置新增选项接口](./options#%E9%85%8D%E7%BD%AE%E6%96%B0%E5%A2%9E%E6%8E%A5%E5%8F%A3-addapi) | | editable | `boolean` | `false` | [编辑选项](./options#%E5%89%8D%E7%AB%AF%E7%BC%96%E8%BE%91-editable) | | editControls | Array<[表单项](./formitem)> | | [自定义编辑表单项](./options#%E8%87%AA%E5%AE%9A%E4%B9%89%E7%BC%96%E8%BE%91%E8%A1%A8%E5%8D%95%E9%A1%B9-editcontrols) | | editApi | [API](../../../docs/types/api) | | [配置编辑选项接口](./options#%E9%85%8D%E7%BD%AE%E7%BC%96%E8%BE%91%E6%8E%A5%E5%8F%A3-editapi) | | removable | `boolean` | `false` | [删除选项](./options#%E5%88%A0%E9%99%A4%E9%80%89%E9%A1%B9) | | deleteApi | [API](../../../docs/types/api) | | [配置删除选项接口](./options#%E9%85%8D%E7%BD%AE%E5%88%A0%E9%99%A4%E6%8E%A5%E5%8F%A3-deleteapi) | | searchable | `boolean` | `false` | 是否可检索,仅在 type 为 `tree-select` 的时候生效 | | hideRoot | `boolean` | `true` | 如果想要显示个顶级节点,请设置为 `false` | | rootLabel | `boolean` | `"顶级"` | 当 `hideRoot` 不为 `false` 时有用,用来设置顶级节点的文字。 | | showIcon | `boolean` | `true` | 是否显示图标 | | showRadio | `boolean` | `false` | 是否显示单选按钮,`multiple` 为 `false` 是有效。 | | initiallyOpen | `boolean` | `true` | 设置是否默认展开所有层级。 | | unfoldedLevel | `number` | `0` | 设置默认展开的级数,只有`initiallyOpen`不是`true`时生效。 | | cascade | `boolean` | `false` | 当选中父节点时不自动选择子节点。 | | withChildren | `boolean` | `false` | 选中父节点时,值里面将包含子节点的值,否则只会保留父节点的值。 | | onlyChildren | `boolean` | `false` | 多选时,选中父节点时,是否只将其子节点加入到值中。 | | rootCreatable | `boolean` | `false` | 是否可以创建顶级节点 | | rootCreateTip | `string` | `"添加一级节点"` | 创建顶级节点的悬浮提示 | | minLength | `number` | | 最少选中的节点数 | | maxLength | `number` | | 最多选中的节点数 | | treeContainerClassName | `string` | | tree 最外层容器类名 | | enableNodePath | `boolean` | `false` | 是否开启节点路径模式 | | pathSeparator | `string` | `/` | 节点路径的分隔符,`enableNodePath`为`true`时生效 |
