View Full Version : Ext.dom.Element.fadeIn()/fadeOut() not working in IE8 in compatibility mode. Bug?

24 Jul 2012, 10:12 AM
Hello, I've been experimenting with fadeIn() fadeOut() effects, but they haven't been working in IE. Works fine in Chrome and Firefox.

As a last gasp I tried opening the IE Developer tools and changed the rendering options to IE7 and VIOLA it worked.

Our web applications are targeted for IE8 (internal apps) and we've often used <meta http-equiv="X-UA-Compatible" content="IE=8"> to ensure that IE starts off in the correct rendering mode. fadeIn()/fadeOut() still don't work with that tag removed, however they DO work with <meta http-equiv="X-UA-Compatible" content="IE=7"> (set to IE7 mode).

Is this a bug?

You should be able to test this yourself by opening IE8 and going to:

1) Tools -> Developer Tools
2) change the "Document Mode" between IE8 Standards and IE7 Standards to see the difference.

In my case leaving the Browser Mode to IE8 Compat View was fine.
