vue.js 路由独享守卫,组件守卫

main.js路由独享守卫:

    path: '/menu', name: "menulink", component: Menu, beforeEnter: (to, from, next) => {
      alert("非登录状态不能进入此页面！");
      next('/login');
    }

main.js后置钩子:

//后置钩子
// router.afterEach((to, from) => {
//   alert('after each ')
// })

      },
      beforeRouteEnter:((to, from, next) =>{
        // alert("hello "+this.name);
        // next();
        next((vm => {
          alert("hello "+vm.name);
        }))
      }),
      beforeRouteLeave:((to, from, next) => {
        if(confirm("确定离开？")==true){
