    <p>I'm working with IE7 and some jQuery dialogs and I'm running into about a 6meg leak per dialog opened. I'm assuming it's to do with closures, but so far everything I've done to remove them haven't helped. At this point I think I've taken care of all the closures except on for a callback function I pass in, but it's still leaking 6 megs even after the dialog is closed and removed. The relevant source code is:</p> <pre><code>function DialogDestroyAndRemove(event) { $(event.target).dialog("destroy").remove(); } function CallbackAndCloseDialog(event) { if (event.data.callback != undefined) { event.data.callback(event.data.callbackResponse); } $("#" + event.data.dialogId).unbind('dialogbeforeclose').dialog('close'); } // alert dialog modal with ok button function AlertDialog(dialogTitle, dialogText, callbackFunction) { // dynamically generate and add a div so we can create the pop-up $('body').append("&lt;div id=\"alertDialog\" style=\"display:none;\" title=\"" + dialogTitle + "\"&gt;" + dialogText + "&lt;/div&gt;"); // define/configure the modal pop-up $("#alertDialog").dialog({ draggable: false, resizable: false, modal: true, autoOpen: true, open: function() { $("#alertDialog").parents('.ui-dialog-buttonpane button:eq(0)') .focus() //focus so the button is highlighted by default .bind('click', { callback: callbackFunction, callbackResponse: 'OK', dialogId: 'alertDialog' }, CallbackAndCloseDialog); }, overlay: { backgroundColor: '#000', opacity: 0.5 }, buttons: { 'OK': function() { } } }).bind('dialogbeforeclose', function(event, ui) { // Close (X) button was clicked; NOT the OK button if (callbackFunction != undefined) { callbackFunction('cancel'); } callbackFunction = null; }).bind('dialogclose', DialogDestroyAndRemove); } </code></pre> <p>One thing I did above that I'm not sure if it's needed was instead of defining the callback for the OK button when it's defined (and therefore having a closure since it's referencing the callback) to define it using a .bind once the dialog is open. I was hoping that being able to pass the callback as part of the data to the click event might help remove the closure.</p> <p>Any ideas what else I can change to get rid of this leak?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
