Ok, so my script tries to request from php results from mysql and load them into a div. The results are based on nid value which is has to send this value is extracted from id="record-#" the record- is removed and the # is left to be used by ajax as id for the nid.

here is the ajax data function

    $(document).ready(function() {

   $(".note").live('click',function() {
      $("#note_utm_con").show();
      $("#note_utm_nt").html("<img src='http://www.ajaxload.info/images/exemples/4.gif' />");

      $.ajax({
         type: "GET",
         url: "_class/view.php",
         data: "ajax=1&nid=" + parent.attr('id'),
         success: function(html){
            $("#note_utm").html(html);
            $("#note_utm_nt").html("");
         },
         error: function (XMLHttpRequest, textStatus, errorThrown) {$("#note_utm_nt").html(errorThrown);}
      });
   });

   $("#note_utm_con_cls").click(function() {
     $("#note_utm_con").hide();
    });
});

and here is the rest of the page

       <div id="note_utm_con" style="display: none;">
<button id="note_utm_con_cls" style="width: 20px;float: right; padding: 2px;clear: both;">X</button>
<div id="note_utm"></div>
<div id="note_utm_nt"></div>
</div>

<?php

}

so when a LI with a class="note" is clicked it triggers AJAX call. The call then uses the ID in the href to extract the $nid from the id="record-

In my case it seems as AJAX is sending the request since view.php returns the fields where the data should be but it does not seem to pass much needed nid so PHP is uable to select proper nid from MySQL to use.

Can some one tell me whats wrong with it and how it can be fixed to get the id?enter code here


Your quotation marks are wrong. Try this:

data: "ajax=1&nid=" + parent.attr('id').replace('record-',''),

Edit: Unless you haven't posted the full code still, you don't actually set parent anywhere. This means that you will use the window.parent object, which surprisingly enough doesn't have an id. You should use this.parentNode.id instead:

data: "ajax=1&nid=" + this.parentNode.id,


From what you've written it looks as if you're passing the parent.attr("id") replace call as a string rather than extracting the variable:

data: "ajax=1&nid=" + parent.attr('id').replace('record-',''),
