判断当前访问网站的设备是否是PC

01//平台、设备和操作系统
02        var system ={
03        win : false,
04        mac : false,
05        xll : false
06        };
07        //检测平台
08        var p = navigator.platform;
09        system.win = p.indexOf("Win") == 0;
10        system.mac = p.indexOf("Mac") == 0;
11        system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
12        //跳转语句
13        if(system.win||system.mac||system.xll){
14            alert("PC访问");
15        }else{
16            alert("非PC访问");
17        }

JS判断访问设备(userAgent)加载不同页面。代码如下：

01function browserRedirect() {
02    var sUserAgent = navigator.userAgent.toLowerCase();
03    var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
04    var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
05    var bIsMidp = sUserAgent.match(/midp/i) == "midp";
06    var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
07    var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
08    var bIsAndroid = sUserAgent.match(/android/i) == "android";
09    var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
10    var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
11    if (! (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM)) {
12        window.location.href = B页面;
13    }
14}
15browserRedirect();

JS判断客户端操作系统类型(platform)来定义不同的字体表现。代码如下：

01// 更详细的探测当前客户端使用的操作系统
02function detectOS() {
03 var sUserAgent = navigator.userAgent;
04 var isWin = (navigator.platform == "Win32") || (navigator.platform == "Windows");
05 var isMac = (navigator.platform == "Mac68K") || (navigator.platform == "MacPPC") || (navigator.platform == "Macintosh") || (navigator.platform == "MacIntel");          if (isMac) 
06 return "Mac";
07var isUnix = (navigator.platform == "X11") && !isWin && !isMac;
08if (isUnix) return "Unix";
09var isLinux = (String(navigator.platform).indexOf("Linux") > -1);
10if (isLinux) return "Linux";
11if (isWin) {
12var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1;
13if (isWin2K) return "Win2000";
14var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 || sUserAgent.indexOf("Windows XP") > -1;
15if (isWinXP) return "WinXP";
16var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1;
17if (isWin2003) return "Win2003";
18var isWin2003 = sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;
19if (isWin2003) return "WinVista"; 
20var isWin2003 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;
21if (isWin2003) return "Win7";
22} 
23return "other"; 
24}
