Memory leaks in IE(6/7/8) when refreshing a frame, which is in a frameset and includes latest jQuery (v.1.5.2)
|Reported by:||Simeon Panayotov||Owned by:|
If jQuery is included in a frame in a frameset and the given frame is refreshed repeatedly, the browser (IE6/7/8) leaks memory. The leak is approximately 1MB per click. The bigger the page, the bigger the leak. I have tested this also with IEJSLeaksDetector, which shows that the window object is a possible leak (which would explain the size of the leak, provided the fact that there is only jQuery on the page.
I suspect this issue is the same as http://bugs.jquery.com/ticket/6421 and since the latter is closed I am opening a new ticket.
Below is the code of a three different pages: one with frameset with two frames, one with a link, hosted in the first frame, and a third one, hosted in the second frame. When the link is clicked the content of the second frame, containing jQuery, is refreshed.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> <html> <head> <frameset cols="50%,50%*" border="0" frameborder="1" framespacing="1"> <frame src="link.html" scrolling="no" frameborder="0" noresize="yes" /> <frame name="jqueryhost" src="" scrolling="no" frameborder="0" noresize="yes" /> </frameset> </head> <body> </body> </html>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title></title> </head> <body> <a href="jqueryhost.html" target="jqueryhost">load jQuery in a frame"</a> </body> </html>
I hope this helps you reproduce the issue.
