3种,全局的、组件的、单个路由独享的
zhaoling906 commentedon Oct 20, 2019
三种导航钩子:
1.全局导航钩子:router.beforeEach(to,from,next) 作用:跳转前进行判断拦截
2.组件内的钩子
3.单独路由独享组件

共有三种守卫:
1:全局守卫:beforeEach,afterEach
2:路由独享守卫:beforeEnter
3:组件级别的守卫beforeRouteEnter,beforeRouteUpdate,beforeRouteLeave
他们执行顺序:全局》路由》组件
除了afterEach全局后置外,其他的守卫中务必要调用next(),否则无法完成导航
还有注意全局前置守卫可以用来进行拦截,(登录拦截)

还有一个缓存组件keep-alive的钩子,activated 每次切换回来的时候会触发,deactivated 每次离开的时候触发
cherry728 commentedon Jun 16, 2020
beforeEach((to, from, next) => {调用next来resolve这个钩子} ),
beforeResolve((to, from, next) => {} ),
afterEach((to, from) => {} )
beforeEnter((to, from, next) => {} ),
beforeRouteEnter((to, from, next) => {next可以传回调,回调里面可以用vm访问实例} ), 内部没有this,因为路由还没confirm
beforeRouteUpdate((to, from, next) => {}),可以拿到this
beforeRouteLeave((to, from, next) => {})

1、全局守卫: router.beforeEach
2、全局解析守卫: router.beforeResolve
3、全局后置钩子: router.afterEach
4、路由独享的守卫: beforeEnter
5、组件内的守卫: beforeRouteEnter、beforeRouteUpdate、beforeRouteLeave
