Vue监听一个数组id是否与另一个数组id相同

数据list，结构为[{id:1,…},{id:2,…}]，数据shoplist，结构为[{id:1,…},{id:2,…}]，判断当shoplist.id等于list.id时显示list的数据。

.vue文件：

<template>  <div class="hello">    <div class="shoplist">      <button @click="clickButtonShopList">click me</button>      <span>shoplist-id:</span><input type="text" v-model="shoplist[shopCount].id">    </div>    <div class="list">      <button @click="clickButtonList">click me</button>      <span>list-id:</span><input type="text" v-model="list[listCount].id">    </div>    <input class="data" v-model="data">    <h2>{{list}}</h2>    <h2>{{shoplist}}</h2>  </div></template>

.js文件：

export default {  data () {    return {      msg: 'Welcome to Your Vue.js App',      shopCount:0,      listCount:0,      data:'',      list:[{id:1,name:'hello'},{id:2,name:'hello'},{id:3,name:'hello'},{id:4,name:'hello'},{id:5,name:'hello'}],      shoplist:[{id:1,name:'hello'},{id:2,name:'hello'},{id:3,name:'hello'},{id:4,name:'hello'},{id:5,name:'hello'}]    };  },  methods:{  clickButtonShopList:function () {      this.shopCount++;      this.shopCount=this.shopCount%this.shoplist.length;      this.getData();    },    clickButtonList:function () {      this.listCount++;      this.listCount=this.listCount%this.list.length;      this.getData();    },    getData:function () {      this.data='';      if(this.shoplist[this.shopCount].id===this.list[this.listCount].id){//        this.data=this.list;        this.data=this.list.map((element)=>{          return element.id+element.name;        }).join(',')      }else {        this.data='';      }    }  },  mounted: function(){    this.getData();  }}

.less文件：

.list{    margin-top: 20px;  }  .data{    width: 500px;    height:200px;    border: 1px solid #666666;    margin-top: 20px;  }

效果：
刚开始时：

两边id不同时：

通过点击使得两边id相同时：
