Ajax jquery returns blank page
<p>I have this JavaScript code:</p>

<pre><code>$(document).ready(function(){ 
           $('#sel').change(function(){

        $.ajax({
                      type: "POST", 
                      url: "modules.php?name=TransProject_Management&amp;file=index",
                      data: "&amp;op=index_stat&amp;stat="+$(this).val(),
                      cache: false,
                      success: function(data) {
                         //alert(data);
                         $("#ajax_results").html(data);
                     }
                  }); 

});
});
</code></pre>

<p>On status change i need to refresh a div without page reload. But it returns blank page. If i try alert the result on success, i get the response, also i checked with inspect element, its ok. The problem is that it returns blank page.</p>

<p>The file i'm working on, is the same( modules.php?name=TransProject_Management&amp;file=index ) i called in ajax.</p>

<p>the html:</p>

<pre><code>&lt;body&gt;
//...
&lt;div id="ajax_results"&gt;
//.....
//somewhere here is the select option &lt;select id="sel"&gt;......&lt;/select&gt;
//.....
&lt;/div&gt;
&lt;/body&gt;
</code></pre>

<p>Any help, would be very appreciated.</p>
