本文實例介紹了JS代碼實現瀏覽器檢測，分享給大家供大家參考，具體內容如下
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 = /(msie/s|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(); 調用方法：(首先得引入js文件，大家應該都懂的)
獲取瀏覽器名:BrowserMatch.browser;
獲取瀏覽器版本:BrowserMatch.version;
獲取所處操作系統:BrowserMatch.OS;
以上就是本文的全部內容，希望對大家的學習有所幫助。
