<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>

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(); }}

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