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：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>
