<scroll-view scroll-y=“true”  bindscrolltoupper=“loadingFirst” bindscrolltolower=“loadingMore” bindscroll=“scroll” scroll-top="{{scrollTop}}">

刚启动是好的，一旦我滑动屏幕，就会交替触发如下三个事件。陷入死循环，我是152900版本。

Invoke event loadingFirst in page: pages/index/index

WAService.js:6 Invoke event scroll in page: pages/index/index

WAService.js:6 Invoke event loadingMore in page: pages/index/index
