.load() doesn't work in Chrome and Firefox

Hi friends,
my code is as follows:

<td><a href="#" id ="putsomeDynamicvalue">ingresar</a></td>  
  
    <script type ="text/javascript">
      $(document).ready(function(){
            $("# putsomeDynamicvalue ").click(function(){
                  var code =$(this).val();
$("#lista").load("http://localhost:8081/Servlet/ingresarOpcion", {codigo:code})
            })
     })
      </script>

This works fine in Explorer 8 (I returned the result of the servlet), but in Chrome and Firefox does not return anything.
Anyone have any idea about this topic?
Greetings, 
Hector
