Vue.js入门(10)路由、路由嵌套、钩子函数
序言
嵌套路由
子路由
路由重定向
路由占位符
路由钩子函数有三种:
1:全局钩子: beforeEach、 afterEach
2:单个路由里面的钩子: beforeEnter、 beforeLeave
3:组件路由:beforeRouteEnter、 beforeRouteUpdate、 beforeRouteLeave
路由参数
{ path: '/user/:id', component: User, props: true },
{ path: '/user/:id', component: User, props: { uname: 'lisi', age: 20 } },
{
path: '/user/:id',
component: User,
props: route => ({ uname: 'zs', age: 20, id: route.params.id })
},
props: ['id', 'uname', 'age'],
路由导航守卫
全局守卫
路由独享守卫
this.$store.commit('UPDATE_TABBAR_STATUS', 'help-center');
this.$router.push({ name: 'setPassWord', query: { hotelStaffType: 'hotel' } });
获取路由参数
1.通过query配置的:this.$route.query
this.action = this.$route.query.action if (this.action === 'add') { this.title = '新建角色' } else if (this.action === 'edit') { this.title = '修改角色' }
2.通过params配置的:this.$route.params
回退到上一步
this.$router.back(-1)
