title: jquery ajax return data not working
body: <p>I have a form with two text boxes and two buttons (one submit button, one button). when I call click the button, it has to make an ajax call with data "CheckRegistration". Finally, it will call ViewRegisteredStudents() function. I am expecting the "resultVal" stirng to be returned to ajax call but it is returning the "resultVal" string and form (two textboxes, two buttons).</p>
  
  <pre><code> $(document).ready(function(){
  
               $(':button').click(function(){
                    $.ajax({
                        Url:"SkiiTripDB.php",
                        type:"POST",
                        data:{call:'CheckRegistration'},
                        dataType:"html",
                        success:function(data){
                               $('div#registeredStudents').html(data);
                        }
                    });
                });
