Vue项目中keepAlive的使用说明(超级实用版)

path:'/index',
name:''index',
component:()=>import('../../index/index'),
meta:{keepAlive:true}

let router=new Router({
    mode:"hash",//1、hash哈希：有#号。2、history历史：没有#号
    base:process.env.BASE_URL, //自动获取根目录路径
    scrollBehavior:(to,from,position)=>{
        if(position){
            return position
        }else{
            return {x:0,y:0}
        }
    },

<keep-alive>
    <router-view v-if="$router.meta.keepAlive"></router-view>
</keep-alive>
    <router-view v-if="!$router.meta.keepAlive"></router-view>

<!-- 逗号分隔字符串 -->
<keep-alive include="a,b">
  <component :is="view"></component>
</keep-alive>
 
<!-- 正则表达式 (使用 `v-bind`) -->
<keep-alive :include="/a|b/">
  <component :is="view"></component>
</keep-alive>
 
<!-- 数组 (使用 `v-bind`) -->
<keep-alive :include="['a', 'b']">
  <component :is="view"></component>
</keep-alive>

<keep-alive :max="10">
  <component :is="view"></component>
</keep-alive>
