jQuery Forum

I wonder if I can see somewhere what events are binded to a DOM
element (in FireBug maybe). Maybe it's obvious, but I just don't know
yet if it's even possible.

Are there any good resources about effective RIA (using jQuery UI) DOM
programming? Lot's of elements, dispatching various events, routing
them to each other, updating through Ajax etc. Generally I'd like to
draw some kind of limits. For example how many DOM there could be, how
many events attached, until user experience gets slow, can I detect
that such limit is close from inside browser, etc. Books, docs,
articles? Does anyone know of any good resource on this topic?

Dialog window looks very bad when it's dragged in FF. Movement is not
smooth at all. It feels like all the contents tend to jump out of it's
boundaries. Not a good experience indeed. I would like to leave only a
thin frame on move event. Is it possible?

I want to store a reference to a particular object using jQuery.data
on another object, can it potentially lead to memory leaks?
And another question. Those objects at some point are dynamically
removed and if that happens will the connection and associated data
automatically be released, or we got to do it manually?

I'm trying to get my mind around getter/setter functionality. I
probably do not understand their purpose properly.
What is the exact difference between setting a property as:
this.someProperty = someValue; and setting it as: this._setData
('someProperty', someValue); What's the point in other words?

I'm building some of my own widgets, but I'm not yet confident with
all those references and closures. Thus, using and passing them here
and there. Is there a convenient tool or something to tell whether I'm
leaking memory?

I'm trying to create a custom progressbar, which among others is of
5px height. It is ok with all other browsers, except IE6 (I know it
dies out, etc, but according to current stats it's still more then
Safari+Chrome+Opera altogether). It looks and feels like something is
keeping it from shrinking to 5px, it does become thinner a bit, but
then it stays constant (approximately at 30px of height)... ?
Any help appreciated.

I know Internet Explorer sucks. It causes a lot of unobvious obstacles
that one should always take by some trickery and dark magic. But now a
HUGE problem comes from our favorite and faithful companion - Firefox.
And the problem is that jerky animation during the movement of the
Dialog box. What's that? Doesn't it suck as much as a whole IE6? Why?

Dropping IE6 I thought whoa - at last or something like that and now
here is IE7.
I'm not sure what the problem is, so I'll just describe it. We got a
dialog box with some uploading stuff happening in it - progressbars,
list of files being uploaded etc. Once file is uploaded, corresponding
item becomes expandable (it show some file properties, actions that
might be applied to it and so on). Now the problem - once we expand
two or three entries, content becomes bigger then the dialog and
logically forces scrollbars to appear. In all major browsers like FF,
Opera, Safari, everything acts and scrolls smoothly. It's only IE that
causes the problems. Content doesn't scroll at all. Scrollbars moves,
but content doesn't and then suddenly it does, but appears on top of
the titlebar. Very wierd. One specific that may be causing this is
that we use animate to expand items smoothly. Although I do not know
why it should affect anything at all anywhere :(
Any idea? Has anyone encountered anything like this? Any solutions?

I've got several map tags with custom areas defined and corresponding
images with usemap attributes. The problem is that those images are
covered with transparent div. I manually intercept events on that div
and route them to the images underneath it. But maps do not seem to
react to routed events anymore. Is it correctable somehow? Or maybe
I'm doing something wrong? The structure cannot be altered,
transparent div must be on top and images and their corresponding maps
must get the click event somehow :(
Any suggestions?

"New in jQuery 1.3:
All triggered events now bubble up the DOM tree. For example if you
trigger an event on a paragraph then it will trigger on that element
first, then on the parent element, and its parent, and so on up to the
document. The event object will have a .target property equal to the
original triggered element. You can prevent the bubbling by calling
stopPropagation() or by returning false from your callback."
http://docs.jquery.com/Events/trigger#eventdata
In other words triggered event should bubble up to it's parent
container, should it? If yes, then I want to catch it on parents level
and trigger it on another child of choice, and so on. But it doesn't
seem to bubble... :(
Any help appreciated.
