## 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 |
| ---------------- | --------------------------------- | ------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| options | `Array<object>`或`Array<string>` | | [选项组](./options#%E9%9D%99%E6%80%81%E9%80%89%E9%A1%B9%E7%BB%84-options) |
| source | `string`或 [API](../../types/api) | | [动态选项组](./options#%E5%8A%A8%E6%80%81%E9%80%89%E9%A1%B9%E7%BB%84-source) |
| delimeter | `string` | `false` | [拼接符](./options#%E6%8B%BC%E6%8E%A5%E7%AC%A6-delimiter) |
| 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) |
| searchable | `boolean` | `false` | 当设置为 `true` 时表示可以通过输入部分内容检索出选项。 |
| searchApi | [API](../../types/api) | | 如果想通过接口检索,可以设置个 api。 |
| statistics | `boolean` | `true` | 是否显示统计数据 |
| selectTitle | `string` | `"请选择"` | 左侧的标题文字 |
| resultTitle | `string` | `"当前选择"` | 右侧结果的标题文字 |
| sortable | `boolean` | `false` | 结果可以进行拖拽排序 |
| selectMode | `string` | `list` | 可选:`list`、`table`、`tree`、`chained`、`associated`。分别为:列表形式、表格形式、树形选择形式、级联选择形式,关联选择形式(与级联选择的区别在于,级联是无限极,而关联只有一级,关联左边可以是个 tree。 |
| searchResultMode | `string` | | 如果不设置将采用 `selectMode` 的值,可以单独配置,参考 `selectMode`,决定搜索结果的展示形式。 |
| columns | `Array<Object>` | | 当展示形式为 `table` 可以用来配置展示哪些列,跟 table 中的 columns 配置相似,只是只有展示功能。 |
| leftOptions | `Array<Object>` | | 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`。 |
