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

var BrowserMatch = {

init: function () {

this.browser = this.getBrowser().browser || "An Unknown Browser";

this.version = this.getBrowser().version || "An Unknown Version";

this.OS = this.getOS() || "An Unknown OS";

},

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 () {

var rMsie = /(msies|trident/7)([w.]+)/;

var rTrident = /(trident)/([w.]+)/;

var rFirefox = /(firefox)/([w.]+)/;

var rOpera = /(opera).+version/([w.]+)/;

var rNewOpera = /(opr)/(.+)/;

var rChrome = /(chrome)/([w.]+)/;

var rSafari = /version/([w.]+).*(safari)/;

var ua = navigator.userAgent.toLowerCase();

var matchBS,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;
