title: jQuery: serialize() form and other parameters
body: <p>Is it possible to send <em>form</em> elements (serialized with <a href="https://api.jquery.com/serialize/" rel="noreferrer"><code>.serialize()</code></a> method) and other parameters with a single AJAX request?</p>
  
  <p>Example:</p>
  
  <pre><code>$.ajax({
      type : 'POST',
      url : 'url',
      data : {
          $('#form').serialize(),
          par1 : 1,
          par2 : '2',
          par3: 232
      }
  }
  </code></pre>
  
  <p>If not what's the best way to submit a form together with other parameters?</p>
  
  <p>Thanks</p>
