路由

export default new Router({
  // mode: ‘history‘,
  routes: [
    {
      path: ‘/‘,
      name: ‘Home‘,
      component: Home,
      meta: {
        keepAlive: true
      }
    }
  ],
  // 页面切换始终在最顶部
  scrollBehavior (to, from, savedPosition) {
    console.log(savedPosition)
    if (savedPosition) {
      return savedPosition
    } else {
      return {
        x: 0,
        y: 0
      }
    }
  }
})

App.vue

  <div id="app">
    <!--<router-view/>-->
    <!--页面返回不刷新-->
    <keep-alive>
      <router-view v-if="$route.meta.keepAlive"></router-view>
    </keep-alive>
    <router-view v-if="!$route.meta.keepAlive"></router-view>
  </div>

调用的页面

  // 在页面离开时记录滚动位置
  beforeRouteLeave (to, from, next) {
    this.scrollTop = document.documentElement.scrollTop || document.body.scrollTop
    next()
  },
  // 进入该页面时，用之前保存的滚动位置赋值
  beforeRouteEnter (to, from, next) {
    next(vm => {
      document.body.scrollTop = vm.scrollTop
    })
  },

杂七杂八

  // 在页面离开时记录滚动位置
  beforeRouteLeave (to, from, next) {
    this.scrollTop = document.documentElement.scrollTop || document.body.scrollTop
    next()
  },
  // 进入该页面时，用之前保存的滚动位置赋值
  beforeRouteEnter (to, from, next) {
    console.log(document.body.scrollTop)
    if (window.performance) {
      console.info(‘window.performance works fine on this browser‘)
    }
    if (performance.navigation.type === 1) {
      console.info(‘This page is reloaded‘)
      next()
    } else {
      next(vm => {
        document.body.scrollTop = vm.scrollTop
      })
