Element Plus el-select el-tree-select 获取选中的label值

select 下拉框通过 @change 选择改变，轮巡方式根据id取name的值 

<el-form-item label="企业类型" prop="entTypeId">
      <el-select v-model="form.entTypeId" placeholder="请选择企业类型" style="width: 220px" @change="entTypeChange">
            <el-option
                v-for="dict in exam_ent_type"
                :key="dict.value"
                :label="dict.label"
                :value="dict.value"
            ></el-option>
      </el-select>
</el-form-item>

//select下拉框取lable值
const entTypeChange = (val:any) => {
   //获取select的方法
   const itemObj= exam_ent_type.value.find((item:any)=>{
    return item.value === val;
  });
  console.log(itemObj);
  console.log(itemObj.label)
  form.value.areaName=itemObj.label;
};

通过@node-click选中节点方式获取选中的值

 <el-form-item label="所属地区" prop="areaId">
            <el-tree-select
                v-model="form.areaId"
                :data="areaOptions"
                :props="{ value: 'id', label: 'label', children: 'children' }"
                value-key="id"
                placeholder="请选择所属地区"
                check-strictly
                default-expand-all
                style="width: 220px"
                @node-click="handleAreaNodeClick"
              />
</el-form-item>

//area所属区域选中，取区域名称
const handleAreaNodeClick = (data: any) => {
  form.value.areaName=data.label;
  console.log(data.label)
}
