浏览器检测JS代码(兼容目前各大主流浏览器)
本文实例介绍了JS代码实现浏览器检测，分享给大家供大家参考，具体内容如下
varBrowserMatch={
init:function(){
this.browser=this.getBrowser().browser||"AnUnknownBrowser";
this.version=this.getBrowser().version||"AnUnknownVersion";
this.OS=this.getOS()||"AnUnknownOS";
},
getOS:function(){
if(navigator.platform.indexOf("Win")!=-1)return"Windows";
if(navigator.platform.indexOf("Mac")!=-1)return"Mac";
if(navigator.platform.indexOf("Linux")!=-1)return"Linux";
if(navigator.userAgent.indexOf("iPhone")!=-1)return"iPhone/iPod";
},
getBrowser:function(){
varrMsie=/(msie\s|trident\/7)([\w\.]+)/;
varrTrident=/(trident)\/([\w.]+)/;
varrFirefox=/(firefox)\/([\w.]+)/;
varrOpera=/(opera).+version\/([\w.]+)/;
varrNewOpera=/(opr)\/(.+)/;
varrChrome=/(chrome)\/([\w.]+)/;
varrSafari=/version\/([\w.]+).*(safari)/;
varua=navigator.userAgent.toLowerCase();
varmatchBS,matchBS2;
matchBS=rMsie.exec(ua);
if(matchBS!=null){
matchBS2=rTrident.exec(ua);
if(matchBS2!=null){
switch(matchBS2[2]){
case"4.0":return{browser:"IE",version:"8"};break;
case"5.0":return{browser:"IE",version:"9"};break;
case"6.0":return{browser:"IE",version:"10"};break;
case"7.0":return{browser:"IE",version:"11"};break;
default:return{browser:"IE",version:"Undefined"};
}
}else{
return{browser:"IE",version:matchBS[2]||"0"};
}
}
matchBS=rFirefox.exec(ua);
if((matchBS!=null)&&(!(window.attachEvent))&&(!(window.chrome))&&(!(window.opera))){
return{browser:matchBS[1]||"",version:matchBS[2]||"0"};
}
matchBS=rOpera.exec(ua);
if((matchBS!=null)&&(!(window.attachEvent))){
return{browser:matchBS[1]||"",version:matchBS[2]||"0"};
}
matchBS=rChrome.exec(ua);
if((matchBS!=null)&&(!!(window.chrome))&&(!(window.attachEvent))){
matchBS2=rNewOpera.exec(ua);
if(matchBS2==null){
return{browser:matchBS[1]||"",version:matchBS[2]||"0"};
}else{
return{browser:"Opera",version:matchBS2[2]||"0"};
}
}
matchBS=rSafari.exec(ua);
if((matchBS!=null)&&(!(window.attachEvent))&&(!(window.chrome))&&(!(window.opera))){
return{browser:matchBS[2]||"",version:matchBS[1]||"0"};
}
}
};
BrowserMatch.init();
调用方法：(首先得引入js文件，大家应该都懂的)
获取浏览器名:BrowserMatch.browser;
获取浏览器版本:BrowserMatch.version;
获取所处操作系统:BrowserMatch.OS;
