关于机器用的操作系统，我们可以随便点击下鼠标就能够获取，但是如何使用javascript获取本机的操作系统类型呢，下面就通过一段代码示例简单介绍一下，希望能够给需要的朋友带来或多或少的帮助。

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"; } }

第二种方法：

<script type="text/javascript">//获取客户端操作系统类型 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); 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"; var isWin2003 = sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1; if (isWin2003) return "WinVista"; var isWin2003 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1; if (isWin2003) return "Win7"; } return "None"; } function locationHref(e){ switch(e){ case 'Mac': window.location.href='http:///'; break; } }</script><script type="text/javascript">var kk=detectOS();alert(kk);</script>

以上就是js获取本机操作系统类型的方法，希望大家有所收获。
