title: Error: missing : after property id
body: <p>I'm getting the following error: missing : after property id in line  </p>
  
  <pre><code>data:{$("#msgForm").serialize() + "&amp;field=msg_from"}
  </code></pre>
  
  <p>The code looks like the following: </p>
  
  <pre><code>$("#msg_from").autocomplete({
    source:
      function (req, resp){
        $.ajax({
         url: "autocompl.asp",
         data:{$("#msgForm").serialize() + "&amp;field=msg_from"}
        });
      }
  }); 
  </code></pre>
  
  <p>Any clue? </p>
