ElementUI中获取select 的label值

在某些业务场景下，我们需要获取select的lable值和value值

获取label值代码如下：

<el-form-item label="测试" 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;
  });
  let getName = ''
  getName = obj.locationName;
  console.log(getName)
}
