<template>
        <component :is="currentView"></component>    
        <!-- 动态组件缓存 -->
        <keep-alive>
            <component :is="currentView">
            </component>
        </keep-alive>
</template>
<script>
    data(){
        return{  
            //通过动态变化currentView来实现动态模块的功能
            currentView: 'v-home1',
        }
    },
    activated() {
        console.log('activate called')
        setTimeout(() => {
            console.log('activate done');
        }, 100);
