Animate function and flash move in Firefox

Reported by: Nyro Owned by: Nyro
Priority: low Milestone:
Component: effects Version: 1.5.2
Keywords: flash overflow Cc:
Blocked by: Blocking:

While animating an element by setting new width or height which contains a flash movie, this flash movie is reloaded.

This occurs only in Firefox.

I tested it with IE8, Safari4, Chrome 2 and Opera 9 all on Vista.

After a quick investigation, it looks like it's coming from these lines:

if ( opt.overflow != null ) = "hidden";

I simply removed them to test and the problem doesn't occur anymore.

Possibly duplicate of #4628 :) Yeah, it break and restarts flash every time, on firefox, when animating. It's the same all since 1.2.x or even before that.

Please fix it already.

I love jquery, but this bug has been a tough one to swallow.

For now, I will minimize an altered version with changes stated in Nyro's post.

It would be great to see this fixed. :)

I just tested the fix on my latest project, and it works perfectly in via OS X 10.5.8 in these mac browsers:

Firefox 3.5.3 (was not working before)

Safari 4.0.3

Opera 10.00 build 6652

Vista OS:

Firefox 3.5.3

Firefox 3.0.11

IE 7.0.60002.18005

IE 8.0.6001.18813

Does anybody of the jQuery team looked at this bug?

Will it be solved in the next release?

I have done several more tests and, from what I can tell, it looks like IE8 is the browser that needs the overflow set...

Not sure why I did not notice it before, but when I removed the overflow from the jQuery source, the animation in IE8 was not working smoothly (if at all)...

My fix:

I reverted back to an un-altered version of jQuery and then added this to my CSS:

#billboard { overflow: auto !important; }

Now FF is happy and IE8 is too!!!

You could even use IE conditional comment to feed IE8 an overflow of hidden.

Anyway, I tested in the latest versions of these browsers:

OS X: Safari, Opera, Firefox

Vista: Safari, IE7, IE8, Firefox

XP: IE6 (via VPC emulator)

Not sure if this fix will help others, but I like this solution much better than modifying the jQuery source. :)

That's a good workaround, thanks. It saves me having to maintain a hacked copy of jquery.

But this is still a bug. In addition to the flash problem, it also creates blinky scrollbars if auto has already been specified.

You can't just remove those lines, since they help keep content clipped for generic animations. But you can easily test for whether the element has overflow already specified:

if ( opt.overflow != null && !/hidden|auto/.test($(this).css('overflow'))) = "hidden";

There's probably a more efficient way to get that css...

Same problem ! same fix ?

I've just add an overflow css rule applying to to the animated tag.

#youranimatedtag {

overflow: hidden;


It works !

How I fix it on my project:


$(document).ready(function() {
	$.noData = {};

Cascading Style Sheets:

#the-flash-tag {
	display: inline-block;
	overflow: hidden;

(In #8903) This has to do with the marginRight hook.

It sounds like we can't fix this inside jQuery in a reasonable way. The first step would be that we need a test case. Can someone provide one?

If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid. Thanks!

Flash will overlay any HTML content by default, but this can be prevented by setting the 'wmode' param and embed attributes to 'transparent'.

<param name="wmode" value="transparent" />

Fix my problem.
