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。

 1 <script type="text/javascript">
 2         function browserRedirect() {
 3             var sUserAgent = navigator.userAgent.toLowerCase();
 4             var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
 5             var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
 6             var bIsMidp = sUserAgent.match(/midp/i) == "midp";
 7             var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
 8             var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
 9             var bIsAndroid = sUserAgent.match(/android/i) == "android";
10             var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
11             var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
12             document.writeln("您的浏览设备为：");
13             if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
14                 document.writeln("phone");
15             } else {
16                 document.writeln("pc");
17             }
18         }
19 
20         browserRedirect();
21     </script>
