element-ui 关于获取select 的label值方法

<el-form-item label="库位" prop="goodslocationid" >
                <el-col :span="15">
                  <el-select v-model="scope.row.goodslocationid" placeholder="货位地址" @change="changelocationvalue">
                   <el-option v-for="lo in locations" :label="lo.locationname" :value="lo.id" :key="lo.id"></el-option>
                  </el-select>
                </el-col>
              </el-form-item>

changelocationvalue(val){
      //locations是v-for里面的也是datas里面的值
      let obj = {};
      obj = this.locations.find((item)=>{
        return item.id === val;
      });
      this.warehousevo2.goodslocationname = obj.locationname;
    },

<el-form-item v-if="ismd" label="业务员名称">
       <el-select v-model="addbm.storemanagername" @change="selectget" filterable style="display:block;" placeholder="请选择门店业务员名称">
        <el-option
         v-for="item in userlist"
         :key="item.id"
         :label="item.name"
         :value="item.id">
        </el-option>
       </el-select>
     </el-form-item>

//下拉框选中事件
  selectget(vid){//这个vid也就是value值
   console.log(ha);
   let obj = {};
   obj = this.userlist.find((item)=>{//这里的userlist就是上面遍历的数据源
     return item.id === vid;//筛选出匹配数据
   });
   console.log(obj.name);//我这边的name就是对应label的
  }
