How to find out if jquery dialog was closed on escape and execute some code

Question

I have a jquery dialog and I need to execute some_code() when I press Esc, or click the cancel button. With the cancel button its easy adding a function to the cancel button.

$( '#mydialog' ).dialog({

    closeOnEscape: true,

    close: function( event, ui ) {
        //some_code();
        $(this ).dialog( 'destroy' )
        },

    buttons: {
        "OK" : function() {
            $( this ).dialog( "close" );
        },
        "Cancel" : function() { 
            some_code();
            $( this ).dialog( "close" );                                                
        }
    }
});

But how can I execute some_code() after pressing ESC? This function must not be called clicking the OK button, so I cannot simply place it to the close event.

Answer 1

After googling around without finding an answer (and that's why I asked the question Q&A style) I started looking into close: function( event, ui ) part and found the solution using event.originalEvent

close: function( event, ui ) {
    //some_code();
    if(event.originalEvent ){
        // triggered by clicking on dialog box X or pressing ESC
        // not triggered if a dialog button was clicked
        some_code();
    }        
    $(this ).dialog( 'destroy' )
    }
