javascript获取本机操作系统类型的方法

 废话不多说了，下面通过一段代码示例介绍一下，希望能够给需要的朋友带来或多或少的帮助。
示例代码：

{

var _pf=navigator.platform;

var appVer=navigator.userAgent;

if(_pf=="Win32" || _pf == "Windows")

{

if(appVer.indexOf("WOW64")>-1)

{

_bit = "64位";

}

else

{

_bit = "32位";

}

if(appVer.indexOf("Windows NT 6.0") > -1 || appVer.indexOf("Windows Vista") > -1)

{

if(_bit=='64位' || appVer.indexOf("Windows Vista") > -1)

{

return 'Windows_vista '+_bit;

}

else

{

return "Unknow1";

}

}

else if(appVer.indexOf("Windows NT 6.1") > -1 || appVer.indexOf("Windows 7") > -1)

{

if(_bit=='32位' || appVer.indexOf("Windows 7") > -1)

{

return 'Windows_7 '+_bit;

}

else

{

return "Unknow";

}

}

else

{

try

{

var _winName = Array('2000','XP','2003');

var _ntNum = appVer.match(/Windows NT 5.d/i).toString();

return 'Windows_' + _winName[_ntNum.replace(/Windows NT 5.(d)/i,"$1")]+" "+_bit;

}

catch(e)

{

return 'Windows';

}

}

}

else if(_pf == "Mac68K" || _pf == "MacPPC" || _pf == "Macintosh")

{

return "Mac";

}

else if(_pf == "X11")

{

return "Unix";

}

else if(String(_pf).indexOf("Linux") > -1)

{

return "Linux";

}

else

{

return "Unknow";

}

}

以上代码很简单的实现了javascript获取本机操作系统类型的方法，一下在通过一段示例代码介绍javascript获取操作系统版本信息
javascript获取操作系统版本信息
示例代码：

var sUserAgent = navigator.userAgent;

var fAppVersion = parseFloat(navigator.appVersion);

//比较浏览器版本大小

function compareVersions(sVersion1,sVersion2){

var aVersion1 = sVersion1.split(".");

var aVersion2 = sVersion2.split(".");

if(aVersion1.length>aVersion2.length){

for(var i=0;i<aVersion1.length;i++)

aVersion2.push("0");

}else if(aVersion1.length<aVersion2.length){

for(var i=0;i<aVersion2.length;i++)

aVersion1.push("0");

}

for(var i=0;i<aVersion1.length;i++){

if(aVersion1[i]<aVersion2[i])

return -1;

else if(aVersion1[i]>aVersion2[i])

return 1;

}

return 0;

}

//检测是否Opera浏览器

fOperaVersion = parseFloat(RegExp["$1"]);

}

无论是获取本机还是非本机的操作系统版本信息，代码都很简单，希望对大家获多或少的有点帮助。
