通过vue刷新左侧菜单栏操作

const router = new VueRouter({
 routes: [
 {
   path: '/commodity-list',
   name: 'commodity-list',
   component: commodityStorage,
   children: []
  }
]

 //每次让路由生成不同的值，用于重新加载组件，达到刷新数据的效果
  computed: {
   key() {
     return this.$route.name !== undefined? this.$route.name +new Date(): this.$route +new Date()
   }
  },
