在uniapp中onPullDownRefresh触发多次的解决方法
微信小程序同样
由于在uniapp中onPullDownRefresh触发多次的，多次下拉会导致圆圈一直再转，而不消失。
pages.json文件 enablePullDownRefresh 一定要设置为true,才可以执行刷新的操作。
{
"path": "pages/business/demo",
"style": {
"navigationBarTitleText": "测试",
"enablePullDownRefresh": true
}
}
解决方案：启动一个定时器来监控，是否触发了两次，以及是否再刷新。
isRefresh: false, //模拟网络请求
isStart: false, //监控二次触发
定时器 来控制刷新按钮的消失

最后，你可以使用一些第三方的下拉刷新的插件，或者使用scollview来自定义刷新。
