Answer 1

try something like this, you don't need to iterate

        $(document).ready(function () {
            $("#submit").click(function(){
                  if($(".select").is(':checked')){
                      alert($(".select:checked").attr('id'));
                  }
            });
        });

Answer 2

Are you only checking one checkbox at a time?

alert( $(".select:checked").attr('id') );

Or, if you have multiple checkboxes checked at once:

$(".select:checked").each(function(){
   alert($(this).attr('id'));
});
