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
rush:js;">
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();
