How to determine whether it was the class or id selector clicked in joint event handler?

sephiith

In the below event handler I need to determine whether it was ID or Class that was clicked and assign a variable based on that.

What would be the easiest way of determining that in an IF statement?

jQuery CODE:

   $(document).on('click', '.inter [class], .inter [id]', function () {
   prevClass = className;
   IF CLASS >>>>>>>   className = this.className.substring(1);
   IF ID >>>>>>>>>>   className = this.id.substring(1);


    var back = '<div id="_'+ prevClass +'"></div>';

    link[prevClass] = original;
    original = link[className];
    link[className] += back;


       $('.inter').fadeTo(250, 0.25, function () {
           $('.inter').html(link[className]); 

           $('.inter').css({'background-image': 'url("' + className + '.png")'});
           $('.inter').fadeTo(250, 1.00);

       });
   });
 });
