title: jQuery filter() compatibility with Internet Explorer 6-7-8
body: <p>I have an ajax call in my page, i use for this particular task the jQuery library. In the response of the ajax call i'd like to parse the response message.</p>
  
  <p>The problem is that this code gives me an error message at IE 6-7-8 (<strong>the weirdness is that IE 9 works perfectly and Firefox works perfectly</strong>):</p>

  <p>Any idea is highly appreciated. Looks like this this line is generating error:</p>
  
  <pre><code>response_str = $(server_response).filter("#response").val();
  </code></pre>
  
  <p>I copy my code related part:</p>
  
  <pre><code>$.ajax({
    type:'POST',
    url:'ajax.php',
  processData: 'false',
  data:{
      data1: 'val1'
      ajax:'true'
          },
  dataType: "html",
  contentType: ''application/x-www-form-urlencoded''
      })
    .done( function(server_response) {
         //the following line generate error
         response_str = $(server_response).filter("#response").val();
            }
       })
  }');
  </code></pre>
