A quick and dirty method is to just use onclick and confirm():

<a href="std_delete.php?student_id=12345" onclick="return confirm('Do you really want to delete this student?');">Delete</a>

A better but more involved method would be to use a modal dialog such as jQuery UI's dialog to prompt the user, then send a POST via ajax to delete the item if confirmed.

<a href="std_delete.php?student_id=12345" class="delete-link">Delete</a>
<script type="text/javascript">
$('.delete-link').click(function(e){
  $('<div>').text('Do you really want to delete this student?').dialog({
    modal: true
    , buttons: {
      "Yes": function(){
        $.post(e.target.href);
      }
    }
  }
});
</script>

The above is just a rough outline of the code, not a functional example. Check the documentation for jQuery and jQuery UI and you can finish it up.
