使用vux实现上拉刷新功能遇到的坑

最近公司在研发app,选择了基于Vue框架的vux组件库，现总结在实现上拉刷新功能遇到的坑：

1.问题：只刷新一次，解决方法：需要自己手动重置状态

this.scrollerStatus.pullupStatus = ‘default'，

2.问题：不能滚动，解决方法：因为启用keep-alive缓存，需要设置

activated () {
this.$refs.scroller.reset()
}

如果还没效果，请在获取后台数据后，执行如下代码

this.$nxtTick(() => {
   this.$refs.scroller.reset()
  })

贴出整个页面的代码。
