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:

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("."); 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 var isOpera = sUserAgent.indexOf("Opera")>-1; var isMinOpera4 = isMinOpera5 = isMinOpera6 = isMinOpera7 = isMinOpera7_5 = false;

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。
