Why are you asking how to do something using any technique other then
JavaScript ... in a newsgroup about JavaScript?!

And check the browser for what?

I need that as mozilla has option to disable javascript. If someone
disable javascript then too the site should go on to some extent hence
I I could get the solution it will be very greatful.

Thanks

All major browsers have ability to disable Javascript, IE6/7, Mozilla
based ones, Opera etc.

There is not any realiable way to detect browser version, not in client
nor server side. Client side is usually made with JS and querying know
features or absence of them. On server side there nothing much to do.
HTTP headers (user agent string) might, or might not contain something
usable, but it's not reliable and out of scope in this NG...

Why just not to stick with very much reliable <noscript></noscript>
method and post nice message to end user to enable JS or switch to
browser that supports JS?

Almost all browsers have the option to disable JavaScript!

You can use the HTTP-Header 'HTTP_USER_AGENT'.

Here's how it's done in PHP:

<?php
echo $_SERVER['HTTP_USER_AGENT'] . "<br /><br />";
$browser = get_browser(null,true);
print_r($browser);
?>

Other Serverside technologies will have different syntax...

IE, Opera and a number of other UAs have that option, too.

Yes, it should. You should therefore learn more about HTML, and how it
intrinsically allows Web documents to be downwards compatible. For the
most simple example:

<a href="foo" onclick="return !window.open(this.href, new
Date().getTime(), 'scrollbars,resizable');">...</a>

Go to gmail with JavaScript disabled and have a look at their
"branching" page that looks at browser capabilities and decides to
which site a user should be redirected.

window.opera yes object Opera browser -- prove me wrong!

Damn!

(allthough, this too is overridable..)

Just as a point of curiousity, how?

I can think of ways to override the User-Agent, and even some ways to
interact with the page. I cannot however think of one way to get that page
to display "yes" on a non-Opera browser.

javascript:window.opera = true; alert(window.opera); isn't quite the same
thing.

It will be proved wrong the day the makers of a new agent decide they
want to spoof Opera and implement a global opera object. These sorts
of "rules" were made to be broken.

Which is why I created the tests in the first place: to show that the
existence of an object alone does not mean anything about the user agent
or the object model it supports.
