javascript实现获取浏览器版本、操作系统类型

代码很简洁，功能很实用，这里就不多废话了，直接给大家奉上代码：

function BroswerUtil() {
}
BroswerUtil = {
//检测浏览器版本
getBrowserVersion: function () {
var agent = navigator.userAgent.toLowerCase();
var arr = [];
var Browser = "";
var Bversion = "";
var verinNum = "";
//IE
if (agent.indexOf("msie") > 0) {
var regStr_ie = /msie [d.]+;/gi;

Bversion = "" + agent.match(regStr_ie)
}
//firefox
else if (agent.indexOf("firefox") > 0) {

} else {
var browser = navigator.appName;
if (browser == "Netscape") {
var version = agent.split(";");
var trim_Version = version[7].replace(/[ ]/g,
"");
var rvStr = trim_Version.match(/
[d.]/g).toString();
var rv = rvStr.replace(/[,]/g, "");
Bversion = rv;
Browser = "IE"
}
}
verinNum = (Bversion + "").replace(/[^0-9.]/ig, "");
arr.push(Browser);
arr.push(verinNum);
return arr;
},
//检测是否是XX浏览器

以上就是这款javascript封装好的检测浏览器版本和操作系统类型的代码库，希望大家能够喜欢。
