Wechat applet WebView prohibits page scrolling without affecting the implementation of overflow scrolling in the business

html,body{
    position: fixed;
    top:0;
    left:0;
    height: 100vh;
    overflow: scroll;
}

Super simple implementation , But I adjusted it many times, but it didn't work , After studying for a long time, I found that the problem is page caching , So in head Tag loading css The file is written in the following way

<link type="text/css" rel="stylesheet" href="css/page.css?t=<?=filemtime("css/style.css")?>">

The above approach may be achievable , But in some cases, the sliding within the business also fails . Today, I have studied another set of methods, namely .

            .bg {
    
                position: fixed;
                top: 0;
                left: 0;
                width: 100vw;
                height: 100vh;
                overflow: auto;
                background-color: #fff;
            }

    <script type="text/javascript">
        setInterval(function () {
    
            $(".bg").focus();
            console.log(1);
        }, 500);
    </script>

Explain it. , What I understand should not be completely correct Namely css Style can achieve the desired effect , But sometimes the page needs to slide dom Loss of focus , Cause failure to slide , You can use js The timer gives this dom Element get focus .
