--- title: Select 选择器 description: type: 0 group: null menuName: Select 选择器 icon: order: 48 --- ## 基本用法 参考 [Options](options) ## 自定义菜单 ```schema: scope="body" { "type": "form", "body": [ { "label": "选项", "type": "select", "name": "select", "menuTpl": "
${label} 值：${value}, 当前是否选中: ${checked}
", "options": [ { "label":"A", "value":"a" }, { "label":"B", "value":"b" }, { "label":"C", "value":"c" } ] } ] } ``` ### 分组展示模式 _单选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "分组", "type": "select", "name": "a", "selectMode": "group", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` _多选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "分组", "type": "select", "name": "a", "multiple": true, "selectMode": "group", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label":

"value": "yunzhongjun" } ] } ] } ] } ``` ### 表格模式 需要额外配置 `columns` 配置，参考 Table 中的说明。 _单选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "表格形式", "type": "select", "name": "a", "selectMode": "table", "columns": [ { "name": "label", "label": "英雄" }, { "name": "position", "label": "位置" } ], "options": [ { "label": "诸葛亮", "value": "zhugeliang",

"label": "韩信", "value": "hanxin", "position": "打野" }, { "label": "云中君", "value": "yunzhongjun", "position": "打野" } ] } ] } ``` _多选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "表格形式", "type": "select", "name": "a", "selectMode": "table", "multiple": true, "columns": [ { "name": "label", "label": "英雄" }, { "name": "position", "label": "位置" } ], "options": [ { "label": "诸葛亮", "value": "zhugeliang", "position": "中单" }, { "label": "曹操", "value": "caocao", "position": "上单" }, { "label": "钟无艳", "value": "zhongwuyan", "position": "上单" }, { "label": "李白", "value": "libai", "position": "打野" }, { "label": "韩信", "value": "hanxin", "position": "打野" }, { "label": "云中君", "value": "yunzhongjun", "position": "打野" } ] } ] } ``` ### 树形模式 _单选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "树型展示", "type": "select", "name": "a", "selectMode": "tree", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` _多选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "树型展示", "type": "select", "name": "a", "multiple": true, "selectMode": "tree", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` ### 级联选择 按列来点选。 _单选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "级联选择", "type": "select", "name": "a", "selectMode": "chained", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` _多选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "级联选择", "type": "select", "name": "a", "selectMode": "chained", "multiple": true, "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` ### 支持搜索 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "带搜索", "type": "select", "name": "a", "selectMode": "chained", "searchable": true, "sortable": true, "multiple": true, "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` ### 延时加载 选型设置 defer: true，结合配置组件层的 `deferApi` 来实现。 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "延时加载", "type": "select", "name": "a", "multiple": true, "selectMode": "tree", "deferApi": "/api/mock2/form/deferOptions?label=${label}&waitSeconds=2", "options": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "defer": true }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ] } ] } ``` ### 关联选择模式 分为左右两部分，左边点选后关联出现右边。左右都可以配置展示模式。 _单选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "关联选择模式", "type": "select", "name": "b", "sortable": true, "searchable": true, "deferApi": "/api/mock2/form/deferOptions?label=${label}", "selectMode": "associated", "leftMode": "tree", "leftOptions": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ], "options": [ { "ref": "zhugeliang", "children": [ { "label": "A", "value": "a" } ] }, { "ref": "caocao", "children": [ { "label": "B", "value": "b" }, { "label": "C", "value": "c" } ] }, { "ref": "zhongwuyan", "children": [ { "label": "D", "value": "d" }, { "label": "E", "value": "e" } ] }, { "ref": "libai", "defer": true }, { "ref": "hanxin", "defer": true }, { "ref": "yunzhongjun", "defer": true } ] } ] } ``` _多选_ ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "关联选择模式", "type": "select", "name": "b", "multiple": true, "sortable": true, "searchable": true, "deferApi": "/api/mock2/form/deferOptions?label=${label}", "selectMode": "associated", "leftMode": "tree", "leftOptions": [ { "label": "法师", "children": [ { "label": "诸葛亮", "value": "zhugeliang" } ] }, { "label": "战士", "children": [ { "label": "曹操", "value": "caocao" }, { "label": "钟无艳", "value": "zhongwuyan" } ] }, { "label": "打野", "children": [ { "label": "李白", "value": "libai" }, { "label": "韩信", "value": "hanxin" }, { "label": "云中君", "value": "yunzhongjun" } ] } ], "options": [ { "ref": "zhugeliang", "children": [ { "label": "A", "value": "a" } ] }, { "ref": "caocao", "children": [ { "label": "B", "value": "b" }, { "label": "C", "value": "c" } ] }, { "ref": "zhongwuyan", "children": [ { "label": "D", "value": "d" }, { "label": "E", "value": "e" } ] }, { "ref": "libai", "defer": true }, { "ref": "hanxin", "defer": true }, { "ref": "yunzhongjun", "defer": true } ] } ] } ``` leftOptions 动态加载，默认 source 接口是返回 options 部分，而 leftOptions 是没有对应的接口可以动态返回了。为了方便，目前如果 source 接口返回的选中中，第一个 option 是以下这种格式则也会把 options[0].leftOptions 当成 leftOptions, options[0].children 当 options。同时 options[0].leftDefaultValue 可以用来配置左侧选项的默认值。 ``` { status: 0, msg: '', data: { options: [ { leftOptions: [], children: [], leftDefaultValue: '' } ] } } ``` ### 人员点选 > 请通过网络面板查看接口请求返回。 实际上就是采用的[「关联选择模式」](#关联选择模式)的 select，注意要看那一部分文档，需要知道怎么动态加载 leftOptions。左侧部分和人员都是通过 source 接口返回。需要懒加载的项通过设置 `defer` 为 true 来标记。左右两部分都支持懒加载。 都是通过 deferApi 来实现，后端根据传过来的参数决定是懒加载树，还是栏加载人员。 - 有 dep 值则是懒加载部门树 - 有 ref 值则是懒加载人员 ```schema: scope="body" { "type": "form", "api": "/api/mock2/form/saveForm", "body": [ { "label": "人员选择", "type": "select", "name": "b", "multiple": true, "sortable": true, "searchable": true, "selectMode": "associated", "leftMode": "tree", "source": "/api/mock2/form/departUser", "deferApi": "/api/mock2/form/departUser?ref=${ref}&dep=${value}" } ] } ``` ## searchApi **发送** 默认 GET，携带 term 变量，值为搜索框输入的文字，可从上下文中取数据设置进去。 **响应** 格式要求如下： ```json { "status": 0, "msg": "", "data": { "options": [ { "label": "描述", "value": "值" // , // "children": [] // 可以嵌套 }, { "label": "描述2", "value": "值2" } ], "value": "值" // 默认值，可以获取列表的同时设置默认值。 } } ``` 适用于需选择的数据/信息源较多时，用户可直观的知道自己所选择的数据/信息的场景，一般左侧框为数据/信息源，右侧为已选数据/信息，被选中信息同时存在于 2 个框内。 ## 属性表 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 | |

`Array` | | 当展示形式为 `associated` 时用来配置左边的选项集。 | | leftMode | `string` | | 当展示形式为 `associated` 时用来配置左边的选择形式，支持 `list` 或者 `tree`。默认为 `list`。 | | rightMode | `string` | | 当展示形式为 `associated` 时用来配置右边的选择形式，可选：`list`、`table`、`tree`、`chained`。 |
