求帮助！jsp如何判断终端是什么设备登录的？？

[chaoloveyou]

由于项目要求，先分为pc版登录和移动设备登录两个页面，请问有什么处理方法和代码能解决自动识别是那个终端过来的，然后分别给不同的终端不同的页面？

function detectOS(){  
    var sUserAgent = navigator.userAgent; 
    var isWin = (navigator.platform == "Win32") || (navigator.platform == "Windows");                                                                        
    var isMac = (navigator.platform == "Mac68K") || (navigator.platform == "MacPPC") || (navigator.platform == "Macintosh"); 
    if(isMac) return "Mac"; 
    var isUnix = (navigator.platform == "X11") && !isWin && !isMac; 
    if(isUnix) return "Unix"; 
    var isLinux = (String(navigator.platform).indexOf("Linux") > -1); 
    if(isLinux) return "Linux"; 
    if(isWin) 
    {  
        var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1; 
        if(isWin2K) return "Win2000"; 
        var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 || sUserAgent.indexOf("Windows XP") > -1; 
        if(isWinXP) return "WinXP"; 
        var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1; 
        if(isWin2003) return "Win2003"; 
    }  
    return "None"; 
}
