Question

in a single page web app, if I create jquery ui dialog on the fly like this:

 $("<div>hello</div>").dialog({ 
      buttons : { 
           "cancel" : function() { 
                $(this).dialog("close");
           } 
      } 
 });

Do I need to do any special clean up after each closing? Do I need to call dialog’s “destroy”?

Answer 1

You should call destroy if you plan to completely re-create the dialog each time it’s opened, as would happen it the code above is called more than once.

If the dialog only gets opened once, it doesn’t matter.
