## DataPicker 级联选择
> **组件名：uni-data-picker**
> 代码块： `uDataPicker`
> 关联组件：`uni-data-pickerview`、`uni-load-more`。
`<uni-data-picker>` 是一个选择类[datacom组件](https://uniapp.dcloud.net.cn/component/datacom)。
支持单列、和多列级联选择。列数没有限制，如果屏幕显示不全，顶部tab区域会左右滚动。
候选数据支持一次性加载完毕，也支持懒加载，比如示例图中，选择了“北京”后，动态加载北京的区县数据。
`<uni-data-picker>` 组件尤其适用于地址选择、分类选择等选择类。
`<uni-data-picker>` 支持本地数据、云端静态数据(json)，uniCloud云数据库数据。
`<uni-data-picker>` 可以通过JQL直连uniCloud云数据库，配套[DB Schema](https://uniapp.dcloud.net.cn/uniCloud/schema)，可在schema2code中自动生成前端页面，还支持服务器端校验。
在uniCloud数据表中新建表“uni-id-address”和“opendb-city-china”，这2个表的schema自带foreignKey关联。在“uni-id-address”表的表结构页面使用schema2code生成前端页面，会自动生成地址管理的维护页面，自动从“opendb-city-china”表包含的中国所有省市区信息里选择地址。
> **注意事项**
> 为了避免错误使用，给大家带来不好的开发体验，请在使用组件前仔细阅读下面的注意事项，可以帮你避免一些错误。
> - 组件需要依赖 `sass` 插件 ，请自行手动安装
> - 如使用过程中有任何问题，或者您对uni-ui有一些好的建议，欢迎加入 uni-ui 交流群：871950839
> - `<uni-data-picker>` 内部包含了弹出层组件 `<uni-data-pickerview>` 外层的布局可能会影响弹出层，[详情](https://developer.mozilla.org/zh-CN/docs/Web/CSS/Common_CSS_Questions)
### 平台差异说明
暂不支持在nvue页面中使用
### 安装方式
本组件符合[easycom](https://uniapp.dcloud.io/collocation/pages?id=easycom)规范，`HBuilderX 2.5.5`起，只需将本组件导入项目，在页面`template`中即可直接使用，无需在页面中`import`和注册`componets`。
如需通过`npm`方式使用`uni-ui`组件，另见文档：[https://ext.dcloud.net.cn/plugin?id=55](https://ext.dcloud.net.cn/plugin?id=55)
## API
### DataPicker Props
|属性名 | 类型 | 可选值 | 默认值 | 说明|
|:-: | :-: |:-: | :-: | :-: |
|v-model |String/ Number | - | - |绑定数据|
|localdata |Array | | |数据，[详情](https://gitee.com/dcloud/datacom)|
|preload |Boolean | true/false | false |预加载数据|
|step-searh |Boolean | true/false | true |分步查询时，点击节点请求数据|
|step-search-url |String | | |分步查询时，动态加载云端数据url格式，`https://xxx.com/{parentValue}`(当前版本暂不支持，下版支持)|
|self-field |String | | |分步查询时当前字段名称|
|parent-field |String | | |分步查询时父字段名称|
|collection |String | | |表名。支持输入多个表名，用 `,` 分割|
|field |String | | |查询字段，多个字段用 `,` 分割|
|where |String | | |查询条件，内容较多，另见jql文档：[详情](https://uniapp.dcloud.net.cn/uniCloud/uni-clientDB?id=jsquery)|
|orderby |String | | |排序字段及正序倒叙设置|
|popup-title |String | | |弹出层标题|
> ****
> `collection/where/orderby` 和 `<unicloud-db>` 的用法一致，[详情](https://uniapp.dcloud.net.cn/uniCloud/unicloud-db)
### DataPicker Events
|事件称名 | 类型 | 说明 |
|:-: | :-: | :-: |
|@change |EventHandle | 选择完成时触发 {detail: {value}} |
|@nodeclick |EventHandle | 节点被点击时触发 |
|@stepsearch |EventHandle | 动态加载节点数据前触发(当前版本暂不支持，下版支持) |
|@popupopened |EventHandle | 弹出层弹出时触发 |
|@popupclosed |EventHandle | 弹出层关闭时触发 |
### 基本用法
#### 云端数据
> **注意事项**
> - 云端数据需要关联服务空间
> - 下面示例中使用的表 `opendb-city-china`(中国城市省市区数据，含港澳台), 在[uniCloud控制台](https://unicloud.dcloud.net.cn/)使用opendb创建，[详情](https://gitee.com/dcloud/opendb)
```html
<template>
<view>
<uni-data-picker placeholder="请选择地址" popup-title="请选择城市" collection="opendb-city-china" field="code as value, name as text" orderby="value asc" :step-searh="true" self-field="code" parent-field="parent_code"
@change="onchange" @nodeclick="onnodeclick">
</uni-data-picker>
</view>
</template>
```
```js
<script>
export default {
data() {
return {
}
},
methods: {
onchange(e) {
const value = e.detail.value
},
onnodeclick(node) {}
}
}
</script>
```
#### 本地数据
```html
<template>
<view>
<uni-data-picker :localdata="items" popup-title="请选择班级" @change="onchange" @nodeclick="onnodeclick"></uni-data-picker>
</view>
</template>
```
```js
<script>
export default {
data() {
return {
items: [{
text: "一年级",
value: "1-0",
children: [
{
text: "1.1班",
value: "1-1"
},
{
text: "1.2班",
value: "1-2"
}
]
},
{
text: "二年级",
value: "2-0"
},
{
text: "三年级",
value: "3-0"
}]
}
},
methods: {
onchange(e) {
const value = e.detail.value
},
onnodeclick(node) {
}
}
}
</script>
```
#### 自定义solt
```html
<uni-data-picker v-slot:default="{data, error, options}" popup-title="请选择所在地区">
<view v-if="error" class="error">
<text>{{error}}</text>
</view>
<view v-else-if="data.length" class="selected">
<view v-for="(item,index) in data" :key="index" class="selected-item">
<text>{{item.text}}</text>
</view>
</view>
<view v-else>
<text>请选择</text>
</view>
</uni-data-picker>
```
> **注意事项**
> `localdata` 和 `collection` 同时配置时，`localdata` 优先
#### 完整示例
```html
<template>
<view class="container">
<uni-data-picker @change="onchange" @nodeclick="onnodeclick" @stepsearch="onstepsearch" @popupopened="onpopupopened"
@popupclosed="onpopupclosed">
</uni-data-picker>
</view>
</template>
```
```js
<script>
export default {

const value = e.detail.value
},
