jquery :

this part of code adds comment through ajax, submission via pressing enter

  $('textarea').keyup(function (event) {                 if (event.keycode == 13 && event.shiftkey) {                     var content = this.value;                     var caret = getcaret(this);                     this.value = content.substring(0,caret)+                                   "\n"+content.substring(caret,content.length);                     event.stoppropagation();                 } else if(event.keycode == 13) {                      $.ajax({                                                 type: "post",                                    url: 'index2.php',                                    data: $("#comment-form").serialize(),                                    success: function(data)                                    {                                         $("#results").html(data);                                    }                                  });                                  $("#comment").val('');                          e.preventdefault();                }               }); 

this part of code explains count updating

              $("span[id^='comlike'] a").click(function() {                 //  alert('aaa');                 var idtest;                 idtest = $(this).attr('id');                 var mystring = idtest;                 var parts = mystring.split("like");                 var thepart = parts[1];                     $.ajax({                                                 type: "post",                                    url: 'like.php',                                    data: 'likeid='+thepart, // serializes form's elements.                                    success: function(data)                                    {                                       $("#likecount"+thepart).html(data);                                      }                                  });                 });
