I'm working on a project to collect web application usage statistics. What
are the recommended ways of detecting whether a browser is JavaScript
enabled and/or capable? Obviously I can write a script to invoke something
on the server, and if it works, then it works. Is there a better way? I'm
looking for the least intrusive way of doing it, from a web application
point of view. i.e. I'd like to be able to drop this into an existing
application without altering anything already there. It would be nice if
there were just a "JavaScript-Enabled" HTTP header.

The gross statistic javascript enabled is almost completely pointless
thing to collect, as it tells you nothing about how capable the script
engine is, NN2 had script support, do you really want to know if it's
script enabled? Does your application work with it?

That's why I'm collecting browser statistics, too, in addition to many other
things. The JavaScript portion is the only part related to this newsgroup.
Do you know how to do it or not?
A small piece of js on the client to create an image and set its
source to a url of your choice? (Match up logged info with your other
browser stats)
If this is for an application involving login then alternatively you
could have some js on the login page populate a hidden form element
(and then hope the user doesn't enable/disable while using the
application.... )
Neither distinguish between js-incapable and js-disabled though....

The recommended approach is to arrange to not have to care. That avoids
the consequences of the aspects of HTTP that make any form of statistics
gathering flawed to the point of being useless, the impossibility of
implementing any mechanism for determining that client-side scripting is
available without an omniscient knowledge of all scriptable web
browsers, and the fact that such information is next to useless anyway.

The NOSCRIPT element was a nice idea that was rendered useless by
suffering short-sighted implementation and specification. They may have
had some value while there was just one scriptable client. They
certainly no longer have any value in Internet browser scripting because
they can do nothing towards covering the third inevitability of script
outcome. And once that third possibility has been covered by design the
NOSCRIPT tag has become superfluous as the consequences of a client's
inability to execute scripts has already been addressed.

No, I know exactly what it's all about, and http://www.w3.org/TR/html401/interac...#edef-NOSCRIPT is a much
more direct link. It is, however, totally irrelevant to my question. I don't
want to *do* something based on JS availability. I just want to *know* about
it so that I can track it.

I always arrange to not have to care. I'm simply curious and would like to
have some numbers to show. I would guess that about 95% of the users that I
code for are using IE 6. Of the rest, most probably use NN 7. That's
something I'm going to find out, and I'd also just like to know how many of
them have turned off JS. I'm guessing that percentage will be very low--in
the neighborhood of 2%. I am also curious as to what about HTTP makes you
think that statistics gathering is pointless. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

After expressing my interest in expanding my new knowledge of HTML and CSS
into the wild realm of JavaScript, I was advised that it is wiser to avoid
it, since not all browsers are use it or are enabled to read it. After
searching for other opinions on the web, I found that some estimate that the
frequency of browsers that can read JS currently is better than 90% -- that
is certainly workable for me!
Do you good people have any thoughts...
