<template>
     <div> 
	     <el-select v-model="value1" multiple placeholder="请选择" @remove-tag="aa"@change="getvalue">
	          <el-option v-for="item in options" :key="item.id"  :label="item.label" :value="item.id">{{item.label}}</el-option>
	    </el-select>
     </div>
</template>

<script>
export default{
     data(){
          return {
         options: [],
         value1: [],
         PersonType:""
          }
     },
     methods:{
         getvalue(){
             console.log(this.value1)
         },
         headSelect(){
             console.log(this.PersonType)
         }
     },
     created(){
    setTimeout(()=>{  //模拟数据
			         var arr =[{
