Router.prototype.goBack = function () {
  this.isBack = true
  this.go(-1)
}

监听路由变化

beforeRouteUpdate (to, from, next) {
  // 如果isBack为true时，证明是用户点击了回退，执行slide-right动画
   let isBack = this.$router.isBack
   if (isBack) {
      this.transitionName = 'slide-right'
   } else {
      this.transitionName = 'slide-left'
   }
   // 做完回退动画后，要设置成前进动画，否则下次打开页面动画将还是回退
   this.$router.isBack = false
     next()
}
