vue通过路由实现页面刷新的方法

 beforeDestroy() {
  this.$root.Bus.$off('judge')
  this.$root.Bus.$off('refreshDetail')
  this.$root.Bus.$off('clearAll')
  this.$root.Bus.$off('upDataCart')
 },

 beforeRouteLeave(to, from, next) {
  this.$root.Bus.$off('judge')
  this.$root.Bus.$off('refreshDetail')
  this.$root.Bus.$off('clearAll')
  this.$root.Bus.$off('upDataCart')

  next()
 },

  beforeRouteEnter(to, from, next) {
   next(()=>{
     window.location.reload()
   })
  },

 this.$router.replace({ name: 'cart' })// 处理返回刷新问题
   this.$router.push({
    path: '/order/order_sure',
    query: {
     sku: sku_str,
     cart: 'cart'
    }
   })

 // 销毁组件，返回刷新
 deactivated() {
  this.$destroy()
 },
