title: jQuery / AJAX - send additional data together with file upload
body: <p>I am uploading files to the server using jQuery:</p>
  
  <pre><code> $.ajax({
      url : 'http://www.example.com',
      dataType : 'json',
      cache : false,
      contentType : false,
      processData : false,
      data : formData, // formData is $('#file').prop('files')[0];
      type : 'post',
      success : function(response) {something}
     });
  </code></pre>
  
  <p>I would like to send additional parameters together with the file. Is it possible? If yes - how?</p>
  
  <p>Thanks!</p>
