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：
function GetOSInfo() { 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(".");

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。
