Mozilla has moved to the DOM, which I think is kind of like a new JavaScript version. It's not backwards compatable with the old version so the document.layers vs document.all test doesn't work any more.

I've tried and tried to write my own or get a script from somewhere else, but I can't seem to be able to come up with anything. Being a programmer, I'd really like to understand the JavaScript on my site. Does anybody know where I can learn about the DOM and the lates cross-browser JavaScript?

Mozilla's DOM docs have been a little helpful, but there aren't any examples.

Thanks.

For a bit of fun: Here's a menu without javascript:

Otherwise, the DOM from a java-script point-of-view is described (as ECMA-script bindings) on

http://www.w3.org/TR/2000/WD-DOM-Lev...e-binding.html

If you're still having trouble, post some code that you think should work, but doesn't, and we'll probably be able to help you. Also, mozilla includes a Javascript debugger and DOM viewer, which is pretty nice to have when you're learning the structure.

One final tip: To seach for Javascript working in in 2000+, search for "getElementById".

Have fun!

Hmmm... Ok, I've got some code that doesn't work. Help me debug this:

alert("hi");

Yes, "alert" doesn't even work. I know it should because it's on the Mozilla site (http://www.mozilla.org/docs/dom/domr...8.html#1028465).
I know I've got JavaSript turned on. What's the matter? Why is this so hard?

Well, it works for me... so something other than the alert is wrong. Try copy&paste the following document into an html-file and then load it in a browser. I've tried both Konqueror and Mozilla, and it works in my end...

Ok, I don't really understand this, but I can get my code to work when I take language="JavaSript" out of the <script> tag. Are we still using JavaScript, or has the name changed?

I'm not sure why your language attribute doesn't work, but anyhow, that attribute is deprecated. Use type instead; or use a META tag as described here:

http://www.w3.org/TR/html4/interact/scripts.html

To quote:

PS: I assume your 'language="JavaSript"' included one more 'c'

Hmmmm... Hopefully "sript" was a typo in my post only. I'll try to remember that "language" is depreciated.

Anyway, I've got something going (sort of) now. Unfortunately, the screen goes blank when it should display a menu. I had this problem once with a pop-up window, which was returning "true" and getting rid of everything else. I don't think these functions are returning anything. I tried void(), but that didn't work.

and the external script file is at

The onmouseover and onmouseout parts call the functions.

Thanks.

I can't reach the above URLs, and anyway, I don't won't to debug an entire application. Can't you try to cut away bits, print to some debug window or whatever until you've have isolated no more than 50 problematic lines? You may even solve the problem yourself this way )

"open" must be a reserved function name. After I fixed that and a few other things, it works.
