I am trying to use the jQuery script that I found at http://swip.codylindley.com/DOMWindowDemo.html on my website to create a lightbox / domwindow popup when a visitor clicks on a link.
Unfortunately, the script does not seem to free up memory when the user closes the dom window. If the user opens and closes the window several times, this leads to a significant slowdown of the page and the user browser crashes.
Here is the jQuery script from the site:
(function($){ //closeDOMWindow $.fn.closeDOMWindow = function(settings){ if(!settings){settings={};} var run = function(passingThis){ if(settings.anchoredClassName){ var $anchorClassName = $('.'+settings.anchoredClassName); $anchorClassName.fadeOut('fast',function(){ if($.fn.draggable){ $anchorClassName.draggable('destory').trigger("unload").remove(); }else{ $anchorClassName.trigger("unload").remove(); } }); if(settings.functionCallOnClose) { settings.functionCallAfterClose(); } }else{ var $DOMWindowOverlay = $('#DOMWindowOverlay'); var $DOMWindow = $('#DOMWindow'); $DOMWindowOverlay.fadeOut('fast',function(){ $DOMWindowOverlay.trigger('unload').unbind().remove(); }); $DOMWindow.fadeOut('fast',function(){ if($.fn.draggable){ $DOMWindow.draggable("destroy").trigger("unload").remove(); }else{ $DOMWindow.trigger("unload").remove(); } }); $(window).unbind('scroll.DOMWindow'); $(window).unbind('resize.DOMWindow'); if($.fn.openDOMWindow.isIE6){$('#DOMWindowIE6FixIframe').remove();} if(settings.functionCallOnClose){settings.functionCallAfterClose();} } }; if(settings.eventType){//if used with $(). return this.each(function(index){ $(this).bind(settings.eventType, function(){ run(this); return false; }); }); }else{//else called as $.function run(); } };

And here is the hyperlink tag from my HTML that opens the light block.
<a href="/php/ajax/edit_map_pin.htm?mAddressBox0=FALSE&mPin_ID=foo" class="AjaxDOMWindow">Change Icon</a>
Here is a screenshot from the siege detailing the memory step, each time the user opens and closes the DOM window from this link. Any help is appreciated. Thank you
