解决Vue中使用keepAlive不缓存问题

1.查看app.vue文件，这个是重点，不能忘记加（我就是忘记加了keep-alive）

<template> <div> <keep-alive><router-view v-if='$route.meta.keepAlive'></router-view> </keep-alive> <router-view v-if='!$route.meta.keepAlive'></router-view> </div></template>

2.查看router.js

{ path:’/loanmessage’, component:loanmessage, name:’loanmessage’, meta: { keepAlive: true, //代表需要缓存 isBack: false, },

3.在需要缓存的页面加入如下代码

beforeRouteEnter(to, from, next) { if (from.name == ’creditInformation’ || from.name == ’cityList’) { to.meta.isBack = true; } next();},activated() { this.getData() this.$route.meta.isBack = false this.isFirstEnter = false },

附上钩子函数执行顺序：

beforeRouteEnter --> created --> mounted --> destroyed

beforeRouteEnter --> created --> mounted --> activated --> deactivated再次进入缓存的页面，只会触发beforeRouteEnter -->activated --> deactivated 。created和mounted不会再执行。
