title: Text disappears on refresh
body: <p>When I run the following code, the req.responseText appears quickly in the div #ajax_msg. When the page refreshes (caused by the location.reload), the div #ajax_msg becomes empty.</p>
  
  <p>JAVASCRIPT CODE:</p>
  
  <pre><code>function jsUpdateCart(){
     var parameter_string = '';
  
     allNodes = document.getElementsByClassName("process");
  
     for (i = 0; i &lt; allNodes.length; i++) {
         var tempid = allNodes[i].id;
         var temp = new Array;
         temp = tempid.split("_");
         var real_id = temp[2];
         var real_value = allNodes[i].value;
         parameter_string += real_id +':'+real_value+',';
     }
  
     var params = 'ids=' + parameter_string;
     var ajax = new Ajax.Updater(
             'ajax_msg', '/welcome/ajax_cart',
              {method:'post', parameters:params, onComplete:showMessage}
      );     
  }
  
  
  
  function showMessage(req){
       $('ajax_msg').innerHTML = req.responseText;
       location.reload(true);
  }
  </code></pre>
  
  <p>Do you have any idea how to fix this problem?</p>
  
  <p>Thanks in advance!</p>
