如何使用el-table+el-tree+el-select动态选择对应值
短信预约 -IT技能 免费直播动态提醒
使用el-table+el-select+el-tree来实现element中el-table表格动态选择对应值
背景描述：
项目组的老大让我们完成一个选择一个下拉框中的值，然后再动态选择该下拉框中树形结构的数值，说起来有点绕，给大家截个图，大家就一目了然了。
其实这个功能的实现主要借助与el-table、el-tree、el-select这三个组件就可以实现。
我碰到的问题：
（1）el-tree数据不显示。
（2）el-tree显示数据后无法绑定某一行。
（3）el-tree不能及时同步显示数据。
但是一开始做的时候一头雾水，因为我是做后端的，其实对前端的知识真的了解的不多，所以，在苦心钻研了一天终于参考了一篇大神的博客，成功解决的这个问题。
在这里附上原文地址：https://www.jb51.net/article/272778.htm
解决问题：
根据大神的文章，我对其中的方法进行了主要的修改，然后按照大神的逻辑，重新修改了页面，发现就成功了，在这里具体什么原因其实我也不知道，但是在这里附上源码，方便大家进行参考。
其实核心主要是三大方面：
（1）第一步，选中下拉框，获取树形数据。
<el-form>
<el-form-item label="用户地址" prop="aloWhTo">
<el-select v-model="form.aloWhTo" @change="testConsistent" placeholder="" readonly filterable style="width:95%" >
<el-option v-for="item in WarehouseOptions" :key="item.whId" :label="item.whName" :value="item.whId">
</el-option>
</el-select>
</el-form-item>
</el-form>
补充：大家在前端指导如何把数据转成树形结构吗？
其实很简单：只需要借助于handleTree（）方法即可，但是在合理提前是你查询的数据是包含这种父子关系的字段的，比如我这里的wliFd这个字段就很关键。
listWarehouseLocationInfo(this.queryParamsByLocation).then(response => {
this.WarehouseLocationInfoList = this.handleTree(response.data, 'wliId', 'wliFId')
console.log("我是最终要返回的数据")
console.log(this.WarehouseLocationInfoList)
})
（2）通过@change="testConsistent"获取树形结构数据treeList，在这里我主要是模拟的树形数据。

}
];
console.log(this.form.aloWhTo)
if(this.form.aloWhTo === 2){
this.treeList = data;
}else {
this.treeList = null;
}
},
（3）修改el-table中的el-table-column，并将el-select、el-tree进行数据绑定，这里具体的参数大家可以参照我推荐的大神的博客，在这里我就不一一介绍了。
<el-table-column label="地址" prop="address">
<template slot-scope="scope">
<el-select
:ref="'address' + scope.$index"
v-model="userlist[scope.$index]['address']"
placeholder="请选择地址类别"
clearable
>
<el-option :value="userlist[scope.$index]['address']" style="height: auto">
<el-tree
:ref="'addressTree' + scope.$index"
:data="treeList"
node-key="wliId"
:props="defaultPropsList"
@node-click="getTypeList(scope.$index)"
>
<span slot-scope="{ node }">{{ node.label }}</span>
</el-tree>
</el-option>
</el-select>
</template>
</el-table-column>
（4）编写getTypeList(scope.$index)，这个方法才是核心，大家按照这个逻辑改一下ref的名字还有数据表的名字即可使用，方便快捷，并且能够实现相应的功能。
getTypeList(index) {
// .getCurrentKey()获取到当前要选择节点的key值
// 使用此方法必须设置 node-key 属性，若没有节点被选中则返回 null
const nodeId = this.$refs['addressTree' + index].getCurrentKey()
// .getNode(nodeId) 根据 data 或者 key 拿到 Tree 组件中的 node
const node = this.$refs['addressTree' + index].getNode(nodeId)
// 根据index给当前元素的categoryName参数赋值
this.$set(this.userlist[index], 'address', node.label)
//this.$set(this.userlist[index], 'categoryNo', node.data.docTypeNo)
// 此时页面上已经可以动态选择
// 这一步是通过判断当前元素的v-model是否有值来控制el-option是否隐藏
if (this.userlist[index].address) {
// .blur()用来隐藏当前展开的下拉选择框
this.$refs['address' + index].blur()
}
},
至此到这里就全部结束了。
（5）在这里附上整个页面的所有代码，方便大家可以再本地进行测试。
