这篇文章主要为大家详细介绍了基于Vue框架vux组件库实现上拉刷新功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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()
   })
