Hi,
Douglas Crockford mentioned in a video on Yahoo! that before removing
an element it is a good idea to purge it's event handlers. I think he
was only refering to the event handlers defined inline in the HTML
element attributes. This purging is because the event handlers create
the circular memory leak in IE.
I am trying to create and observe this memory leak with with IE6 and
the example below. I can't see any memory leaking.
Is my test faulty or am I missing something else?
Thank you,
Peter
