Detect when any dialog opens jQuery

Question

I have several dialogs that open like this

 $("#dialog").load(URL);
 $("#dialog").dialog(
           attributes,
           here,
           close: function(e,u) {
                    cleanup
           }

The issue is that I have hundreds of these dialogs. I do not want to manually have to create an open: attribute for each one. Is there any way I can monitor the entire document for a dialog open such as

 $(document).on("open","#dialog",function() {
     Do something
 })

Answer 1

From jQuery API:

$( ".selector" ).on( "dialogopen", function( event, ui ) {} );

So you could do what you said probably:

$("body").on("dialogopen",function(e,u){
    alert('dialog open!');
});
