javascript:判断浏览器类型和客户端操作系统 （2009-06-02更新）

 //检测客户端环境function ClientMentInfo(){var me = this;var appVer = navigator.userAgent;this.GetBrowserName = function (){if(appVer.indexOf("MSIE")>0) return "IE"; else if(appVer.indexOf("Firefox")>0) return "Firefox"; else if(appVer.indexOf("Chrome")>0) return "Chrome"; else if(appVer.indexOf("Safari")>0) return "Safari"; else if(appVer.indexOf("Camino")>0) return "Camino"; else if(appVer.indexOf("Konqueror")>0) return "Konqueror";else return "其它";}this.GetOSInfo = function (){var _pf = navigator.platform;if(_pf == "Win32" || _pf == "Windows"){if(appVer.indexOf("Windows NT 6.0") > -1 || appVer.indexOf("Windows Vista") > -1){return 'Windows Vista';}else if(appVer.indexOf("Windows NT 6.1") > -1 || appVer.indexOf("Windows 7") > -1){return 'Windows 7';}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")];}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";}}this.OS = me.GetOSInfo();//操作系统类型this.IeVer = null;this.Bs_lang = (navigator.appName == 'Netscape'?navigator.language:navigator.browserLanguage);//浏览器语言版本this.Bs_Name = me.GetBrowserName();//浏览器名称//浏览器版本if(this.Bs_Name=='IE'){var _msie = appVer.match(/MSIE /d./i).toString();this.Bs_Version = this.IeVer = _msie.replace(/MSIE (/d)./i,"$1");}else{this.Bs_Version = appVer;}this.Ie6 = this.IeVer==6 ? true: false;this.Ie7 = this.IeVer==7 ? true: false;this.Ie8 = this.IeVer==8 ? true: false;}//客户端信息var CMInfo = new ClientMentInfo();

 

利用javascript来判断客户端操作系统和客户端浏览器类型的方法（2009-04-24更新，把它门改进为一个类）
增加了对windows vista和windows 7的判断 （2009-06-02更新）
