The example in this article explains the detailed code of js to determine whether the current page is opened on a mobile device or on a PC. I share it with you for your reference. The specific content is as follows

 var browser = {
              versions: function () {
                var u = navigator.userAgent, app = navigator.appVersion;
                return {     //移动终端浏览器版本信息
                  trident: u.indexOf('Trident') > -1, //IE内核
                  presto: u.indexOf('Presto') > -1, //opera内核
                  webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
                  gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
                  mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
                  ios: !!u.match(/\(i[^;]+;( U;)&#63; CPU.+Mac OS X/), //ios终端
                  android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或uc浏览器
                  iPhone: u.indexOf('iPhone') > -1, //是否为iPhone或者QQHD浏览器
                  iPad: u.indexOf('iPad') > -1, //是否iPad
                  webApp: u.indexOf('Safari') == -1 //是否web应该程序，没有头部与底部
                };
              }(),
              language: (navigator.browserLanguage || navigator.language).toLowerCase()
            }            
            if (browser.versions.mobile) {//判断是否是移动设备打开。browser代码在下面
                var ua = navigator.userAgent.toLowerCase();//获取判断用的对象
                if (ua.match(/MicroMessenger/i) == "micromessenger") {
                    //在微信中打开
                   setInterval(WeixinJSBridge.call('closeWindow'),2000);
                }
                if (ua.match(/WeiBo/i) == "weibo") {
                    //在新浪微博客户端打开
                }
                if (ua.match(/QQ/i) == "qq") {
                    //在QQ空间打开
                }
                if (browser.versions.ios) {
                    //是否在IOS浏览器打开
                } 
                if(browser.versions.android){
                    //是否在安卓浏览器打开
                }
            } else {
                //否则就是PC浏览器打开
                window.close();
            }

Code 2: js determines whether the user’s browsing device is a mobile device or a PC

In a recent website page, it is necessary to display different page styles according to the user's access device. The main purpose is to determine whether the user is accessed by a mobile device or a computer browser.

The js judgment processing code is given below for reference.

<script type="text/javascript">
    function browserRedirect() {
      var sUserAgent = navigator.userAgent.toLowerCase();
      var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
      var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
      var bIsMidp = sUserAgent.match(/midp/i) == "midp";
      var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
      var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
      var bIsAndroid = sUserAgent.match(/android/i) == "android";
      var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
      var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
      document.writeln("您的浏览设备为：");
      if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
        document.writeln("phone");
      } else {
        document.writeln("pc");
      }
    }

    browserRedirect();
  </script>

I have tested using browsers on computers, Android devices, iPhones, and iPads. This code is feasible and the judgments on all devices are correct.

The above is the entire content of this article, I hope it will be helpful to everyone’s study.
