list頁(yè)面上computed監(jiān)聽(tīng)的pageList 沒(méi)有數(shù)據(jù)，add添加頁(yè)面可以正常添加到store里
<template>
? <div>
??? 新聞列表
?<ul>
????? <li v-for="(item,index) in pageList"
????????? :key="index">
??????? {{item.title}}-{{item.content}}
????? </li>
??? </ul>
? </div>
</template>
<script>
? import store from '@/store'
? export default{
??? name:'List',
??? store,
??? computed:{
????? pageList(){
??????? return store.state.lists
????? }
??? }
? }
</script>

找到問(wèn)題原因了，list頁(yè)面里computed:{
????? pageList(){
??????? //每次 監(jiān)聽(tīng)stroe里list 的狀態(tài) 變化
????? return store.state.newList
//其中newList是store.js文件里state里定義的數(shù)據(jù)
????? }
??? }
