jQuery UI Dialog - halt close event

Is there a way to stop a close event for a jQuery UI Dialog?

I have a dialog modal with a form. When the user closes the dialog, I'd like to prompt "Continue without saving changes?" [Yes] [No]. The [Yes] button continues and closes the dialog as expected. The [No] button will stop the close event and keep the dialog open.

Is this possible?

Justin answer works fine to show the modal. If you want to cancel the closing, your function should return false, like that:

$( ".selector" ).dialog({
   beforeClose: function(event, ui) 
    { return check_if_unsaved_changes(..); }
});

check_if_unsaved_changes should return true if the dialog should close and false if it should not close.

Yes, you can use the beforeClose option. From the docs:

This event is triggered when a dialog attempts to close. If the beforeClose event handler (callback function) returns false, the close will be prevented.

Code examples

Supply a callback function to handle the beforeClose event as an init option.

$( ".selector" ).dialog({
   beforeClose: function(event, ui) { ... }
});
