title: How to pass serialized form data to datatables?
body: <p>I use datatables with server-side handler. Major code:</p>
  
  <pre><code>$("#dt-flats-build").dataTable({
     processing: true,
     serverSide: true,
     ajax: {
                  url: "/api.json",
                  data: $('form#filter').serialize()
     },
     });
  </code></pre>
  
  <p>and I have a form with filter. I pass form data to the api.json as addential params.</p>
  
  <p>So, I can pass only fields one by one, but not all fields from form. 
  Do you have any ideas?  </p>
