I am using jquery in my web page. I see a lot of memory leak happening and after a while the whole browser grinds to a halt. I used the sieve tool and noticed that there is a contsant increase in the no. of DOM elements, everytime by a no. of 4.

Am I doing something wrong in the way I have associated events? Or is it because I am using setTimeout to redraw my app every X seconds?

Event association:

$('.bir_Names').click(showNames); The selector $('.bir_Names') evelautes to a set of some 300 elements each of which call the function on click.

setTimeout Every X mins I remove every single HTML element in the app and rebind fresh data and associate the events. I use jquery remove() to delete elements. have tried innerHTML = '' and empty() also.

I see a jump of nearly 30-40 MB for every redraw and Sieve indicates that none of the deleted nodes are actually removed.

Anyhelp would be greatly ap开发者_StackOverflow社区preciated. This thing is driving me nuts.

Thanks.


You don't mention which browser, but some googling seems to indicate that this is a known problem with IE. Here's one potential workaround:

http://forum.jquery.com/topic/possible-memory-leak-in-remove-and-empty

Note that that's referring to a 1.2.x release of jQuery. Before you do anything, make sure you are running the latest 1.6.x release to first see if the defect has already been fixed within jQuery.

[EDIT] ack...you DO state your browsers...'all'...so maybe disregard that first link.
