                alert(idconf);

Answer 1

You should rather use .on() for event delegation:

 $('body').on('click','.marks',function(){
          var idconf = $(this).attr('idd');
          alert(idconf);
         return false;
 });

Answer 2

Try with -

$('.marks').on('click', function(e) {
    alert($(this).attr('id'));
    return false;
})

And change -

<a id=$iid class='marks' href='?i=$iid'>Confirm</a>

If you dont want to use id then you can try data attribute also.
