How do you test what broswer a person is using on a web site?

[Pestilence]

I'm the webmaster for a student organization and I want to be able to test what broswer a person uses and then what version it is so that I could then make a direction page that says whether or not their version is too old to be properly viewed with my web site.

Check out the source code in the following page. It does a browser test.

This won't test version, but this simple dimple piece of JavaScript will determine if it's IE, or Netscape:

<script language="JavaScript">
if (navigator.appName == "Microsoft Internet Explorer")
{
location.href = "index2.html";
}
else
{
location.href = "index3.html";
}
</script>

In that case, would this be a browser/version script? This is taken(cut/pasted) from the site I linked to earlier.

<SCRIPT LANGUAGE="javascript">
<!--
window.name='MainFrame';

function open_content_win(win) {
browser_name = navigator.appName;
browser_version = parseFloat(navigator.appVersion);
str= win;

if (browser_name == "Microsoft Internet Explorer" && browser_version < 5.0) {
searchWin = window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=620,height=480,status=no,location=no,toolbar=no,menubar=n o');

window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=620,height=480,status=no,location=no,toolbar=no,menubar=n o');
}
else if (browser_name == "Netscape" && browser_version <= 4.01) {
searchWin = window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=620,height=540,status=no,location=no,toolbar=no,menubar=n o');

window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=520,height=540,status=no,location=no,toolbar=no,menubar=n o');

if (browser_version >= 3.0) {
searchWin.focus();
}
searchWin.refer = self;
}
else {
searchWin = window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=640,height=520,status=no,location=no,toolbar=no,menubar=n o');

window.open(str,'searchWin','resizable=no,scrollbars=yes,wid th=640,height=520,status=no,location=no,toolbar=no,menubar=n o');

searchWin.focus();
searchWin.refer = self;
}
}

//-->
</SCRIPT>

Aye, that's a bloated script that is doing stuff you don't need though. Just plug in those "navigator.appVersion" paremeters in your 'if' statements, and adjust accordingly.

Example:

<script language="JavaScript">
if (navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion >= 5.0)
{
location.href = "index2.html";
}
elseif (navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion < 5.0)
{
location.href = "index3.html";
}
else
{
location.href = "index4.html";
}
</script>

Sorry, Griz. I had used the Rip out and paste method straight from the source code on Netscape's site. It was definitely bloated, but not knowing Java myself, I did not know how to par it down.

Quite a few scripts here. Aren't Java and JavaScript different languages?

Hey whatever floats your boat James!

And yeah Slippy, JavaScript and Java are two different things entirely. JavaScript is a web scripting language, and Java is a full blown Object Oriented Programming Language.

Thanks for the help all, I'm sure I'll be able to rip all the code I need from there.

Yeah they are. Java is more of a C++ type of language, whereas javascipt is pretty much strictly used in web pages, and is client-sided (its loaded onto the clients computer as the page downloads and runs from there). For anyone who cares...
