{    path: '/application',    title: '我的工作',    icon:'code-working',    name: 'application',    component: Main,    children: [      {        path: 'index/:id', title: '我的申请', name: 'myApplication', component: resolve => {          require(['@/views/application/index'], resolve);        }      },      {        path: 'index/:id', title: '我的待办', name: 'have not done', component: resolve => {          require(['@/views/application/index'], resolve);        }      },      {        path: 'index/:id', title: '我的已办', name: 'have been done', component: resolve => {          require(['@/views/application/index'], resolve);        }      }    ]  },

这三个路由绑定的是同一个组件，在

created(){   console.log(this.$route.params.id)}

里面这种动作只会执行一次,也就是只能拿到该组件创建时的路由id，

const User = {  template: '...',  watch: {    '$route' (to, from) {      // 对路由变化作出响应...    }  }}

或者使用 2.2 中引入的 beforeRouteUpdate 守卫：

const User = {  template: '...',  beforeRouteUpdate (to, from, next) {    // react to route changes...    // don't forget to call next()  }}
