This issue is still present in latest jQuery version with on my iPad 2.

found a working (the bug shows up) jsfiddle at stackoverflow:

http://jsfiddle.net/ambiguous/zWC3R/

(interestingly the bug also shows up when trying to change the jquery version within jsfiddle - so jsfiddle alone would also be a good example)

after rebooting the ipad it worked again for some time without any problem - but after a little while the bug was present again.

Has somebody found a bugfix for this problem?

Changed May 02, 2012 07:56PM UTC by anonymous comment:8

I also had this issue verbatim. I rebooted my iPad and the issue went away which indicates to me the bug maybe with Safari.

Seems to me that the problem is not being caused by jQuery - if it were, the issue would be consistently reproducible. Please stop posting "me too" unless you have verifiable evidence.

I have managed to reproduce it consistently as follows:

1. Open a page with an $.ajax() call and a link to a PDF

2. Click link to download PDF

3. Open PDF in iBooks, effectively puts Safari in background

4. Put Safari in foreground, will show the PDF

5. Press back button to go back to the page with $.ajax() call.

Restarting Safari solves the issue until I do the above again. Maybe this helps.
