【技术支持】关于html中移动端innerwidth的问题

首先看问题

移动端web相关

屏幕是375*667

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8" />
        <!-- <meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=0" /> -->
        <meta name="viewport" content="width=device-width, initial-scale=2.0" />
        <title>Document</title>
        <style>
            * {
                margin: 0;
            }
            #test {
                height: 100px;
                background-color: aquamarine;
            }
        </style>
    </head>
    <body>
        <div id="test"></div>
        <script>
            let div = document.getElementById("test");
            console.log(window.innerWidth); //375
            console.log(document.documentElement.clientWidth); //375
            div.style.width = 970 + "px";
            console.log(window.innerWidth); //971
            console.log(document.documentElement.clientWidth); //375
        </script>
    </body>
</html>

此代码在桌面端正常，在移动端有些异常，移动端的window.innerWidth不是视口大小，会变化

解决办法就是<meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=0" />，添加user-scalable=0
