title: JQuery Post sends form data and not JSON
body: <p>Trying to send json. Here's my function:</p>
  
  <pre><code>var object = ... ;
  
  $.ajax({
        type: 'POST',
        url: '&lt;url&gt;',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        data: object
      });
  </code></pre>
  
  <p>But whenever I check Chrome, it always sends it as query params:</p>
  
  <pre><code>Request Payload:
  startDate=Wed+Dec+19+2012+19%3A00%3A00+GMT-0500+(EST)&amp;endDate=Thu+Dec+20+2012+19%3A00%3A00+GMT-0500+(EST)&amp;
  </code></pre>
  
  <p>How do I get it to send as JSON?</p>
