JavaScript Get Browser Version _ Basics

Work needs to go through JS to get the name of the browser currently in use and version number, on the internet a lot of data have a key word is Navigator.appname, but this method gets the name of the browser is only two, ie or netscap, it can be used to determine whether the use of IE, but I want to get specific browser product name such as Firefox,chrome.

Copy Code code as follows:

function Broswerutil () {
}
Broswerutil.prototype = {
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;
Browser = "IE";
Bversion = "" + Agent.match (Regstr_ie)
}
Firefox
else if (Agent.indexof ("Firefox") > 0) {
var regstr_ff =/firefox\/[\d.] +/gi;
Browser = "Firefox";
Bversion = "" + Agent.match (REGSTR_FF);
}
Chrome
else if (Agent.indexof ("Chrome") > 0) {
var regstr_chrome =/chrome\/[\d.] +/gi;
Browser = "Chrome";
Bversion = "" + Agent.match (regstr_chrome);
}
Safari
else if (Agent.indexof ("Safari") > 0 && agent.indexof ("Chrome") < 0) {
var Regstr_saf =/version\/[\d.] +/gi;
Browser = "Safari";
Bversion = "" + Agent.match (REGSTR_SAF);
}
Opera
else if (Agent.indexof ("opera") >= 0) {
var Regstr_opera =/version\/[\d.] +/gi;
Browser = "Opera";
Bversion = "" + Agent.match (Regstr_opera);
} 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;
},
WB: (function () {
var useragent = Navigator.userAgent.toLowerCase ();
Alert (useragent)
return {
IsIE6:/msie 6.0/.test (useragent),//IE6
