With JQuery, you can try something like that, assuming ajaxlink is a class used for both your tags:

$('.ajaxlink').click(function() {
  var position = $(this).offset();
  position.left = position.left + $(this).width() - $('#data_sprite').width();
  position.top = position.top + $(this).height();
  $('#data_sprite').css(position)
});
