    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?

                  Perhaps you wanted to reply to David and not me as David is the one that

                      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.

                          It is unusable without a pointing device. A mouse isn't the only
                          pointing device available.

                          would use a css menu except that someone that doesn't know anything

                          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.
                                  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.
                                  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.

                                      about HTML, Javascript, etc. can not change the menu.
                                      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.
