159961 - Javascript menu doesn't work in Mozilla browser

Status: RESOLVED WONTFIX

(Tech Evangelism Graveyard :: English US, defect)

Description

[Marjorie Lamkin]

This menu code works in both Netscape 4.x and Internet Explorer, we use a
variation of it for our apps.  Opera almost works with it (it's not perfect),
but the Mozilla browser seems to completely ignore it.  You should be able to
bring this page up and menus should appear when you click the areas where it
suggests.

Unfortunately, there is a lot of outdated stuff lurking on the Netscape site. 
Mozilla does not provide backward compatibility for Netscape 4's non-standard 
DHTML features

http://developer.netscape.com/evangelism/docs/articles/updating-dhtml-web-
pages/ may be useful.

Marjorie: good catch!

This page on our own site is using old code dating back to 1997 or so.
Specifically, an external JS file called "menu.js"; a key function there
is showMenu(), which has this structure:


                function showMenu( etc.)
                {
                  if (document.layers)
                  {
                    // do a lot of things
                  }
                  else if (document.all)
                  {
                    // do a lot of things
                  }
                }


This function will not cause any errors in Mozilla/N6/N7, but 
it won't actually do ANYTHING, since |document.layers| is only
supported in NN4, and |document.all| is only supported in IE.

Neither of these proprietary DOM extensions are supported in
Mozilla/N6/N7. Reassigning to Tech Evangelism for disposition.
I know this issue has come up before; but I'm not sure of how
we handle this. 

Compare bug 89383, "netscape.com - Dynamic HTML menus does not work".
Also filed against a "smith_menu" page; so perhaps this bug is just
a duplicate of that one, then -
