detectOS() 方法返回的结果是字符串，如果操作系统是xp就返回"WinXP"，如果是wind7返回"Win7"。。。。。。。。

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") || (navigator.platform == "MacIntel");
if (isMac) return "Mac";
var isUnix = (navigator.platform == "X11") && !isWin && !isMac;
if (isUnix) return "Unix";
var isLinux = (String(navigator.platform).indexOf("Linux") > -1);

var bIsAndroid = sUserAgent.toLowerCase().match(/android/i) == "android";
if (isLinux) {
if(bIsAndroid)
return "Android";
else
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";
var isWinVista= sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;
if (isWinVista) return "WinVista";
var isWin7 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;
if (isWin7) return "Win7";
}
return "other";

}

document.writeln("您的操作系统是：" + detectOS());
