Memory leak with framesets in modal dialog

[dberthia]

In IE6/7, jQuery 1.3.2 introduces a browser memory leak when opening a modal dialog window that contains a frameset. The leak is made worse if there are nested framesets in the popup window, and pages within the frameset include jQuery. See attached files to reproduce the problem.

Unzip and launch index.htm in IE6. Use Task Manager to monitor as you open/close the popup window.

Anxiously awaiting the outcome of this.

I'm heartened to see some activity on this. We had to remove jQuery from our modal dialogs because of this, which obviously seriously restricts us from a development standpoint.

[dberthia]

I'm now disheartened so see 1.4 roll out and still no activity on this.

Try this fix to 1.4.2

add to line 67: FSP change DOMContentUnLoaded,

add to line 756: FSP change DOMContentUnLoaded = function() { Original

for ( var id in jQuery.cache ) {

if ( jQuery.cache[ id ].handle ) { Try/Catch is to handle iframes being unloaded, see #4280

try {

jQuery.event.remove( jQuery.cache[ id ].handle.elem );

} catch(e) {}

}

}

FSP extension window.detachEvent( "onload", jQuery.ready ); window.detachEvent( "onunload", DOMContentUnLoaded ); window.jQuery = window.$ = jQuery = null;

}; FSP change end

change line 2627: if ( window.attachEvent && !window.addEventListener ) {

FSP change

window.attachEvent("onunload", DOMContentUnLoaded );

}

Seems to still exist in 1.4.x - marking as valid.

I believe that this has been resolved. Please re-open if that is no longer the case.

I'm checked the attached test case on ie7 and 6 with jQuery 1.6.1 and the leak is still occurs.
