title: Can I post JSON without using AJAX?
body: <p>I have some data, lets say:</p>
  
  <pre><code>var dat = JSON.stringify(frm.serializeArray())
  </code></pre>
  
  <p>I want to submit this to the server using a roundtrip (aka, non ajax).</p>
  
  <p>I know this is possible, but I can't find any literature on it.  Ideas?</p>
  
  <p>(I am using jQuery, if that makes it easier)</p>
  
  <p>EDIT: while all of these answers so far answer the question, I should have included that I want an "content type" of "application/json"</p>
