js判断当前浏览器是pc端还是移动端

根据用户的访问设备的不同来显示不同的页面样式，主要是判断移动设备还是电脑浏览器访问的。

下面给出js判断处理代码，以作参考。

 <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>
