PHP获得唯一ID

Question

With help from this forum I wrote the code:

<?php
 if ($_POST['action'] == "delete_admin") {
       echo json_encode(array("result"=>true));
       exit;
 }

 while($row = mysql_fetch_array($query9)) {
  $res = array(array("adm"=>$row['id']));

  foreach($res as $a) {
   echo'<div id="adAdmListItem">&bull;&nbsp;&nbsp;&nbsp;'.$row['admin'].'
    <span id="adRemoveAdm">
     <span delete-admin="'.$a['adm'].'">[x]</span>
    </span>
   </div>
  }
 }
?>

And jquery:

$('[delete-admin]').on('click',function() {
    var remove = $(this).parents('div#adAdmListItem');
    var admin_id = $(this).val();

    $.post('index.php',{action: 'delete_admin', admin_id: admin_id},function(data) {
        remove.hide();

    },'json');
});

This functions work properly. When I click on the [x] the item of list (admin) will be hidden. But I need get an id of admin (where I clicked [x]). Received id I have to send to php by ajax or XMLHttpRequest. The problem is I can't get the admin id. (I tried set the unique id - required in while loop, but I can't get it by jquery). It's easy with php but in this case the page will be reload, I wanna miss that.

如果我正确理解了代码和问题，则可以尝试以下操作：

var admin_id = $(this).attr('delete-admin');
