Re: [jQuery] Re: How to check whether an element is bound to an event or not?
In jQuery 1.3.x, .live() only works for a subset of event types.
jQuery 1.4 extends support to all event types:
Possible event values: click, dblclick, mousedown, mouseup,
mousemove, mouseover, mouseout, keydown, keypress, keyup
Currently not supported: blur, focus, mouseenter, mouseleave,
change, submit
http://docs.jquery.com/Events/live#typefn
Kudos for rolling your own solution for 1.3.x with the onfocusin event.

Re: [jQuery] Re: How to check whether an element is bound to an event or not?
on certain versions of IE i had issues where the .live() function just didn't work. no click events at all were firing only on IE. not sure if this has been fixed. On Sun, Jan 3, 2010 at 9:23 AM, Md. Ali Ahsan Rana wrote: > Hi, > Thanks for your reply. It helped me a lot. > > Regards >
