小程序Android版本touchmove 事件侦听- 当前 Bug 的表现(可附上截图) 在安卓端绑小程序定一个view 的touchmove 事件时,纵向触摸滑动每秒只有5次事件回调 但是用网页端复现的时候表现正常 - 预期表现 - 复现路径 - 提供一个最简复现 Demo 小程序代码: - index.wxml <view class="layer" bindtouchmove="layerMove"> <text>{{touchMovesPerSecond}}</text> </view> - index.js const app = getApp() Page({ data: { touchMovesPerSecond: 0 }, touchMovesArray: [], layerMove: function(event) { this.touchMovesArray.push(new Date()) const now = new Date() this.touchMovesArray = this.touchMovesArray.filter(time => time > now - 1000) this.setData({ touchMovesPerSecond: this.touchMovesArray.length }) } }) --------------------------------------------分界线------------------------------------------ Web 端代码: <!DOCTYPE html> <html> <head> <title></title> <style type="text/css"> body, html { background-color: #4e4d4d; margin: 0px; padding: 0px; height: 100%;} #container { background-color: red; height: 100%; } </style> </head> <body> <div id="container"> <p id="count"></p> </div> <script> const touchMovesArray = [] const handleMove = function() { touchMovesArray: [], touchMovesArray.push(new Date()) const now = new Date() touchMovesArray = touchMovesArray.filter(time => time > now - 1000) document.querySelector('#count').innerHTML = touchMovesArray.length } var el = document.querySelector('#container') el.addEventListener("touchmove", handleMove, false); </script> </body> </html>
