Vue监听一个数组id是否与另一个数组id相同的方法

DevilLittle 人气:0

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:

Vue 监听数组id

两边id不同时:

通过点击使得两边id相同时:
