试图在php循环中隐藏jquery中的特定div

Question

I have this form being outputted from a PHP while loop :

echo '<div id="postCont" class="postCont'.$pid.'" style="block;">
    <div id="clLink">
      <a id="clLink" href="'.$plink.'" target="_blank"" title="'.$ptitle.'">'.$ptitle.'</a>
    </div>
    <div id="clDate">Posted on '.$pdate.'</div>
    <div id="clDesc">'.$pdesc.'</div>

    <form method="post" class="ibadForm">
        <input type="hidden" name="id" value="'.$pid.'">
        <input type="hidden" name="hiddenBad" value="yes">
        <input type="image" src="../img/bad.png" name="subBad" value="Bad" class="bad">
    </form>
</div>';

I am trying to remove the individual .postCont when the ibadForm is clicked with jquery.

$(".ibadForm").submit(function(e) {
     var url = "add_form.php"; 
     var id = <?php echo $pid?>;
     $.ajax({
          type: "POST",
          url: url,
          data: $(this).serialize(),
          success: function(data)
         {
             $('.postCont' + id).hide();
         }
     });
     e.preventDefault();
 });

It submits the form to add_form.php fine but doesn't hide the postCont. If I remove the id from the class then it hides all post Cont's. Can anyone tell me where I am going wrong?

You could use closest() to get the parent div then hide it using hide() method like :

$(".ibadForm").submit(function(e) {
  var url = "add_form.php"; 
  var id = <?php echo $pid?>;
  var _this = $(this);

  $.ajax({
    type: "POST",
    url: url,
    data: $(this).serialize(),
    success: function(data)
    {
      _this.closest('.postCont').hide();
    }
  });
  e.preventDefault();
});

NOTE : You should store the $(this) object that refer to the clicked form in some variable (_this in my example) then use it inside the success callback since $(this) inside callback doesn't refer no more to the form, e.g :

_this.closest('.postCont').hide();

Hope this helps.
