This page demonstrates how to detect the web browser and operating system a visitor is using on your website. The detector has been updated to detect the new Google Chrome web browser.


How Does It Work?
When you are developing very elaborate webpages with Javascript, you have undoubtedly run into problems when developing for a web browser that operates on multiple computer operating systems. This detection script actually detects the web browser being used and the operating system and assigning a number to the combination detected. In your javascript, all you need to do is to reference "net_browser" which will contain the number. Here's the actual code that you can copy-n-paste: 

<script language="javascript" type="text/javascript">
<!--
/* OS / Browser Detect.  Written by Joe McCormack.  www.virtualsecrets.com */
var net_browser = 0;
function wbrowsertype() {
/*
__ net_browser flag values based on OS/Browser __
	0 = Undetermined OS / Browser
	17 = Undetermined OS / Browser
MAC OS:
	2 = Unknown Browser
	3 = Internet Explorer
	4 = Safari
	5 = Firefox
	6 = Netscape
	7 = Opera
	8 = Camino
	9 = Firebird
	26 = Google Chrome
WINDOWS OS:
	10 = Unknown Browser
	11 = Internet Explorer
	12 = Firefox
	13 = Netscape
	14 = Opera
	15 = Camino
	16 = Firebird
	25 = Google Chrome
UNKNOWN OS:
	17 = Unknown Browser
	18 = Safari
	19 = Internet Explorer
	20 = Firefox
	21 = Netscape
	22 = Opera
	23 = Camino
	24 = Firebird
	27 = Google Chrome
