I recently upgraded from loading JQuery 1.4.4 to 1.5.0 with Google CDN. When I upgraded, my backgroundPosition animations stopped functioning.
For example, I used to have:
$(this).stop().animate({backgroundPosition: ['-1800px 0px', 'easeOutExpo']},5000);
This no longer works in version 1.5.0 loaded from Google CDN. Let it be noted that I am using JQuery UI 1.8.9, also loaded from Google CDN.
Has anyone else encountered similar problems?
This is actually a known bug, it’s breaking quite a few things with jQuery UI. My recommendation, for the interim is just refer to an older jQuery version, something like this:
