--- title: Picker 列表选择器 description: type: 0 group: null menuName: Picker icon: order: 35 --- 列表选取，在功能上和 Select 类似，但它能显示更复杂的信息。 ## 基本用法 默认和 Select 很像，但请看后面的 pickerSchema 设置。 ```schema: scope="body" { "type": "form", "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm", "controls": [ { "type": "picker", "name": "picker", "label": "picker", "options": [ { "label":"A", "value":"a" }, { "label":"B", "value":"b" }, { "label":"C", "value":"c" } ] } ] } ``` ## 配置 pickerSchema 可以配置 pickerSchema，实现弹框 crud 选择模式，更多 crud 配置可查看 crud 文档，选择之后最终的值通过 `valueField` 来设置。 ```schema: scope="body" { "type": "form", "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm", "debug": true, "controls": [ { "type": "picker", "name": "type4", "joinValues": true, "valueField": "id", "labelField": "engine", "label": "多选", "source": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample", "size": "lg", "value": "4,5", "multiple": true, "pickerSchema": { "mode": "table", "name": "thelist", "quickSaveApi": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample/bulkUpdate", "quickSaveItemApi": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample/$id", "draggable": true, "headerToolbar": { "wrapWithPanel": false, "type": "form", "className": "text-right", "target": "thelist", "mode": "inline", "controls": [ { "type": "text", "name": "keywords", "addOn": { "type": "submit", "label": "搜索", "level": "primary", "icon": "fa fa-search pull-left" } } ] }, "columns": [ { "name": "engine", "label": "Rendering engine", "sortable": true, "searchable": true, "type": "text", "toggled": true }, { "name": "browser", "label": "Browser", "sortable": true, "type": "text", "toggled": true }, { "name": "platform", "label": "Platform(s)", "sortable": true, "type": "text", "toggled": true }, { "name": "version", "label": "Engine version", "quickEdit": true, "type": "text", "toggled": true }, { "name": "grade", "label": "CSS grade", "quickEdit": { "mode": "inline", "type": "select", "options": ["A", "B", "C", "D", "X"], "saveImmediately": true }, "type": "text", "toggled": true }, { "type": "operation", "label": "操作", "width": 100, "buttons": [ { "type": "button", "icon": "fa fa-eye", "actionType": "dialog", "dialog": { "title": "查看", "body": { "type": "form", "controls": [ { "type": "static", "name": "engine", "label": "Engine" }, { "type": "divider" }, { "type": "static", "name": "browser", "label": "Browser" }, { "type": "divider" }, { "type": "static", "name": "platform", "label": "Platform(s)" }, { "type": "divider" }, { "type": "static", "name": "version", "label": "Engine version" }, { "type": "divider" }, { "type": "static", "name": "grade", "label": "CSS grade" }, { "type": "divider" }, { "type": "html", "html": "
