5944 - [BLOCK]ender- Mouse Events don't work with *GFX* OPTGROUP or OPTION elements

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[David Hyatt]

The onchange handler for SELECT elements fires at the wrong time.  It is being
fired when the mouse is clicked in the SELECT element, which seems to just be
wrong.

It should be fired when the element loses focus AND has changed since last
gaining the focus.  This is specified in the DOM Level 2 working draft and also
in the JavaScript 1.2 Reference on developer.netscape.com.

You can't attach simple click handlers to SELECT elements.  The click handler on
the SELECT element never fires.  Moreover, a click on a child OPTION element
never bubbles up, either to an OPTGROUP or to the SELECT.  I am assuming that
all mouse events are broken.

Take a look at the HTML4 spec on w3.org to see the set of events that
SELECT, OPTGROUP, and OPTION should be prepared to respond to.

This is a high priority bug, since between the inability to register click
handlers, and the disfunctional onchange handler, we have no way of using combo
boxes as reliable widgets.

Reassigning to Pollmann. Please solicit help from Pixley if needed.

Changed severity to "blocker". It certainly is for the Editor, and probably is
for other groups as well

I'll be trying to get most of this in M6.

The OnChange behaviour is reported as bug 3322.

OnClick works fine for me on SELECT listboxes.
http://blueviper/forms/onclick.html

OnClick for SELECT comboboxes works in the text entry field but not the
drop-down list.  This should be also fixed for M6.
http://blueviper/forms/onclick2.html

Mouse events on options and optgroups are not handled at all right now and I
haven't done work to assess them yet - so they may not make it into M6.

[Eric Pollmann]

I've made note of the fact that mouse events on the drop down list of a combo
box don't get bubbled up (or in fact ever enter the event system) in bug 3322.

The only remaining issue for this bug not covered by 3322 is that events don't
get routed to options or optgroups, but instead start out at the select.

This remaining problem should go away when GFX widgets become the default.

Postponing this one until "much later"

[Peter Trudelle]

Need this early in M10!

Comment 11

[Eric Pollmann]

I'm splitting this bug, one for GFX widgets (which should be fixed ASAP) and one
for native widgets (which is low priority and may not get fixed right away if
ever).  Since this is the bug with the most history, I'll leave this as the GFX
bug.  Reassigning Kevin McCluskey.  I'll hold on to the Native bug 11797 just as
a bookmark.

Moving to M10

gfx selects enabled as default as of Aug 19, 1999 4:00PM.

Comment 14

http://blueviper/forms/onclick.html seems to have a javascript error ('dump not
defined') and it does nothing in 4.7 or 5.0.
http://blueviper/forms/onclick2.html tells me that onclick is working.
I suppose that means that this is fixed for gfx widgets. Marking verified.

Putting on [PDT]+ radar.
