Memory leaks in IE(6/7/8) when loading frame, which is in a frameset and includes latest jQuery (v.1.5.1 and above) with solution

[romero83@…]

Ok. So most probably I found the problem for this memory leak issue. Let's see the latest Jquery 1.6.1 source code. The problematic code line is 1172, which looks like this:

input = div.getElementsByTagName( "input" )[ 0 ];

I don't know why, but if you add this statement into a variable, then IE do some kind of memory issue. After I commented out that line, no more memory leak appeared in IE7.

I did a workaround in version 1.5.1 and it worked.

See ​http://bugs.jquery.com/ticket/8863 for more details.

I hope this helps to fix this problem.

It would be great if that fixes the issue. CC addy.

Thanks romero83 for the input but it doesn't solve the problem for me :-(
Also jQuery 1.4.4 is not working fine for me I also get a memory leak of about 1Mb per load.
Any other ideas or a solution coming up from jQueries side?

Null created elements in support to avoid leaks in IE. Tested IE6-8. Leaks are contained to the byte. Fixes #9294.

Thanks for your proposed solution but unfortunately it's not solving the problem in IE6 (still about 1Mb of leak)

@Booab. According to my tests, there are no leaks in the support module in IE6. Are you sure you are testing against the git version of jQuery? If so, please provide a test case so that we can confirm.
