i use this code, and work for me:
$(document).ready(function(){
    $('form#myform').submit(function(){
          $("#hiddenIframe").remove();    
          $('').appendTo('body').attr({'id': 'hiddenIframe'});
          var Frame = $('#hiddenIframe');
          var newSrc = 'about:blank?nocache=' + Math.random(); //force new URL
          Frame.attr('src', newSrc); 
          var iframe = $('#hiddenIframe').load(function(){
              var response = iframe.contents().find('body').html();
              var txt = $.parseJSON(response);
              $('#message').append(txt.message);
              if(txt.error == false){
                   $.ajax({
                       type: 'POST',
                       url: '?myurl',
                       dataType: 'json',
                       data: {
                           //some data
                       },
                       success: function(data){
                           //some action
                       } 
                   });                                         
              }           
         });                                             
    });
});
</code></pre>

<p>This generate a new iframe on each submit, my PHP part</p>

<pre><code>$this->message['error'] = true;
$this->message['message'] = "Problem!";

echo/print json_encode($this->message);
</code></pre>

<p>Try this</p>
