Very Slow IE Multiple Selector performance on big html page

Reported by: anonymous Owned by: anonymous

Component: unfiled Version: 1.5.1
Keywords: Cc:
Blocked by: Blocking:

This occurs on a rather big html page: 150kBytes and more than 700 "input, select, td and textarea" objects.

Using IE6 or IE8, the unresponsive-script popup appears.

The bug existed in jQuery 1.4.4 too.

Example code slow statement:


Same effect but now fast:

This was introduced in 1.4.3 when use of sourceIndex was dropped.

For this case your "IE-only" solution works for all browsers, so just use that. Also, consider using event delegation via .delegate() rather than using .tooltip() for all 700 elements.

Thanks! I copied the 1.4.2 sourceIndex sorting code to our local jquery 1.5.2 version.
