小程序列表分页查询数据，应用scroll-view总是出现多触发bindscrolltolower的情况，有遇到过的或者解决过的么。请教。。。
测试页面代码：
mocklist.js代码：

这个问题我这边也出现了，下拉和上拉，upper和lower都会出现多次调用。ip6，wx版本6.7.2，真机调试下
你好，请提供一下出现问题的机型和微信版本，以及能复现问题的简单代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）。
安卓小米MIX2也可以轻松复现。
onPageScroll这个事件会触发多次，加了请求锁都不行，所以改用scroll-view，但是scroll-view中用canvas又会抖动。二者起码解决其一吧。
会不会是数据还没加载完成就又发生了误操作，建议加个wx.showloading()，直到加载完成才消失
