title: Can I do this? $("msgcntDiv").data("newMessageCnt.php");
body: <p>I have a variable in a span tag:</p>
  
  <pre><code> echo "&lt;span class='headings_sub' id='msgcntDiv'&gt;You have ".$numOfMessages." &lt;/span&gt;";
  </code></pre>
  
  <p>My script:</p>
  
  <pre><code> &lt;script&gt;
      $(document).ready(function() {
           var reload = function(){  
         $("msgcntDiv").load("newMessageCnt.php");
      }
      window.setInterval(function() {
          $("#msgcntDiv").load(reload);
      }, 10000);
       });   
  &lt;/script&gt;   
  </code></pre>
  
  <p>"newMessageCnt.php" has one line:</p>
  
  <pre><code>&lt;?php
  include('header_application.php');
  $pageValue = "dashboard";
  $obj_clean-&gt;check_user();
  echo $numOfMessages = $obj_clean-&gt;getUnopenedMessagesCount($_SESSION['user_id']);    
  ?&gt;
  </code></pre>
