- 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
})
}
})

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>
