DOM Problems

This post is for those struggling to figure out why there Drop Down
Menus and other scripts are not working using th DOM.

There are slight DOM problems with ONMOUSEOVER and ONMOUSEOUT events
of parent and child elements. When the child element fires its
ONMOUSEOVER event it also fires the ONMMOUSEOUT event. When this
happens you get a canceling of script (Like using timers for
instance). Because of this you have to check to make sure you are
still in the parent element to keep its ONMOUSEOUT event from firing.

For more information on this topic view: http://www.faqts.com/knowledge_base/view.phtml/aid/1606.

To view a site that is using this script go here:

To view the non-working site with almost the same script go here:

It is worth noting that your primary navigation interface is unusable
without a mouse. It also breaks completely when scripting is
disabled. You might as well have used CSS menus.

It is unusable without a pointing device. A mouse isn't the only
pointing device available.
It also breaks completely when scripting is disabled.
People who disable scripting (after they figure out how) remind me of
Netscape 4 users.

Yeah, we know you can't disable CSS, right?

I know of the limitations of this effect. My menu is not in the
question. This was just a post to help those struggling with the same
issue I was The DOM, because I have seen several places that that was
the issue.

Right.

Some people don't have a choice and some agents don't feature
scripting at all.

I am not advocating CSS-only menus. But when CSS is disabled, the
links used to make up the menus should still work. So it would be
slightly better than the OP's current approach, where disabling JS
results in dead links.

Sorry about that. I didn't mean for that message to be for you. I
would use a css menu except that someone that doesn't know anything
about HTML, Javascript, etc. can not change the menu. In Javascript i
can make it simple for someone that doesn't know coding to change the
menu. The original menu I worked off of is http://www.alvaschools.com/.
It is also Javascript.

It seems to me that you wouldn't have to know JS to update the content
of an HTML page. As far as CSS menus go, you wouldn't have to do
anything but update the markup. Someone who is unable to update HTML
markup is probably not the best candidate to work on your pages.

When you turn off JavaScript, the entire menu disappears and is
replaced by the message: "Your browser does not support script."
That's what users of aural (or text-based) browsers will first hear
(or see) on entering your page. Furthermore, keyboard users cannot
navigate your site, even with JavaScript. Suffice to say that
whomever was responsible for the original menu did not know what they
were doing. It follows that you shouldn't have replicated their
effort. You would have been better off using the example I gave you
in the previous thread about your menus.

The thought of someone modifying Javascript code that doesn't know
anything about Javascript and/or HTML is a worrisome thought. Especially
the code in the alvaschools site. Are they supposed to be able to know
what HighSubBgColor is supposed to do? The comment says:

Background color when mouse is over on subs

Hell, that confuses *me* and I know what it is.

Just curious, but what are BeforeStart, AfterBuild, BeforeFirstOpen and
AfterCloseAll supposed to be for? They don't do anything.
In Javascript i can make it simple for someone that doesn't know
coding to change the menu.
It is equally trivial to allow them to modify a CSS driven menu.
I would dare say it is a lot easier.
The original menu I worked off of is http://www.alvaschools.com/.
It is also Javascript.
I think that before you start trying to make things "easier" on the
editors, you should understand what it is that you are trying to make
"easier".

I have said it before: people may not have the choice.
"People who disable scripting (after they figure out how)"

Now, people who "may not have the choice" won't be going and disabling
it on there own. That rules them out of my group of people.
IOW, they may not need to do anything to their user agent for it not to
support client-side scripting (fully).
Can you name a main stream browser that is script disabled by default?
That includes, but is not limited to, UAs that don't
provide the support in the first place.
If the UA doesn't provide it, then the user won't very well be disabling
it now would they? That must rule those people out of the group I was
referring to.

But, just to be fair, and try to satisfy your pedantic desires, let me
rephrase what I wrote:

"People who knowingly, and willingly, disable scripting (after they
figure out how), remind me of Netscape 4 users."

Now, all you have to do is get a simple decent grasp of what I think of
when I talk about "Netscape 4 users" and I doubt you do.

Simply put? You don't have a clue what I meant.

Fix your signature and you might gain a little credibility.
