JavaScript does not work in Firefox

[minnesotti]

Hi there,

I subscribed to a photographic pictures-hosting website which is heavy
on JavaScript. My preferred latest browser Mozilla Firefox does not
work with it -- no pictures are displayed and no buttons react to
clicking. The website's helpdesk says it should work with Firefox, and
could not offer any more advices. The JavaScript Console shows that
there are numerous errors occuring. It looks like the web browser does
not recognise JavaScript code. When viewing the website with Internet
Explorer, JavaScript code works al'right and the website works. I am
using ZoneAlarm Pro as a firewall... I heard it might clip the
JavaScript code. When I turned ZAPro off, the website still was not
viewable. I viewed the website through anonymizer which re-wrote
JavaScript code... and surprise-surprise... I could view the
picture-hosting website. I would hypothesize that the anonymizer
re-writes the JavaScript code to the old code understandable by Firefox
(however, the website helpdesk claims that their website works with
latest Firefox, and I could not find any other computer with Firefox to
check if the problem is only with my computer). Or, there might still
be something running on my computer which clips the JavaScript code
like ZAPro which probably still runs even after turning it off. Help me
please, with the suggestion of possible causes. Thanks.

It may help if you give the URL, so that people can check what

The picture-hosting website is http://www.zenfolio.com/ . When I go
there, no button work and no images are displayed. Oh, I did not
mention in the previous posting that I checked the "JavaScript Enable"
box in the Options menu. The JavaScript Console gives the error
messages: "Error: event is not defined", "Error: dom.attachEvent is not
a function" and "Error: this.domEvent has no properties". Thanks.

When I go there, everything is working, and the JavaScript console
gives no errors, warnings or anything.

Hi minnesota, I've just looked at the URL you are talking about and
everything works fine for me. I too have ZA as a firewall (although I
use the Internet Suite rather than Pro) so I don't think that's your
problem.

Have you enabled Java and Javascript in Firefox? You can find the
setting in tools/options/content.

Hi Els and SteveG,

I have enabled Java and JavaScript (and everything else) in Firefox. At
some stage, I have installed Java Runtime Environment (JRE) 1.3 on my
computer to run a particular program, and that particular website
cannot run with JavaScript from JRE1.3. However, when I am checking my
web browser with the http://www.cyscape.com/showbrow.aspx?bhcp=1 , it
says that my browser is using Sun's Java vesion 1.4.2 which is
acceptable for the picture-hosting website. I tried to uninstall Sun's
JRE 1.3 (and left untouched JRE 1.4.2), but it gives no effect.

I went to the "Control Panel" on my MS Windows XP SP1, and saw there
"Java Plug-in" both from MS ("Virtual Machine") and from Sun. I clicked
on Sun's (?) "Java Plug-in" and saw that the box for only "Internet
Explorer" box is checked to make it using the Java Plug-in. I checked
the box next to "Mozilla" to nake it using the Java Plug-in, but the
window popped up saying that the computer was "Unable to change browser
settings". I made a search on the Internet to learn how to manage this
problem. This indeed was a common problem, but no cure was offered.

This was when I wrote to this Usenet group.

No problems here - Firefox/1.5.0.4 with ZoneAlarm

"attachEvent" is an IE specific method, so it's unsurprising that it
doesn't work in Firefox. However, on a properly coded page, that code
should never be executed by Firefox anyway, so I'd say it's a case
of bad programming.

Are your Firefox by any chance identifying itself as IE? In that case,
it just shows why browser detection is bad.

Either the site is IE specific (and their support is clueless or
lying) or it's just badly coded and thinks you are using IE for some
reason.

Learn the difference between Java and JavaScript.

I suspect your browser is set to pretend to be IE, and the site's
browser detection code is too stupid to know the real browser you're
using.

Whoah! Wait a minute "attachEvent" is a MS only proprietary command, for
Firefox and other compliant browsers it should be "addEventListener".

Couple things could be at play here. Maybe they are browser sniffing in
the wrong way, should be by object detection:

// attach events after page loads
if( window.addEventListener ) {
window.addEventListener('load',initJS,false); //legacy
} else if( document.addEventListener ) {
document.addEventListener('load',initJS,false); //proper
} else if( window.attachEvent ) {
window.attachEvent("onload", initJS); //IE only
}

But maybe they are doing it from the user agent string (bad way). Are
you using any extension that changes your Firefox's user agent string?

Must be, looked at JavaScript on the site and the browser detection *is*
via User Agent string and not by object detection. You must have some
extension that is changing your Firefox's User Agent string, 'IE View'
or something?

I used to write little programs in JavaScript many years ago, so I know
the difference. I checked the web browser via the website which I
mentioned above, and it says that I have Firefox. It seems al'right at
this end.

Hmm... after a week of twisting, I just twisted something in ZA Pro,
and the picture-hosting website loaded into my Firefox browser. The
JavaScript Console does not complain anymore that there are errors.
However... still, there are some problems. If I go to the pictures made
by the photographers, the pictures cannot download into the browser.
Perhaps, I should give it up.

Having just perused this thread, that might be a good idea. You may be
better finding a picture hosting site that doesn't rely on shoddy javascript
coding to present the basic content to the client. I'm sure there are plenty
out there.
