Vue实现页面跳转上一页面不刷新
step1：配置路由缓存
export default new Router({routes: [{path: '/hello',name: 'hello',meta: {keepAlive: true // 需要缓存}}],})
step2:配置App.vue文件中的的<router-view/>
<keep-alive><router-view v-if="$route.meta.keepAlive"></router-view></keep-alive><router-view v-if="!$route.meta.keepAlive"></router-view>
step3：使用this.$router.back()返回
按钮的返回事件 this.$router.go(-1)换成this.$router.back()
