title: how to uppercase all the String elements of backbone serialized form
body: <p>When i submit a form i send a serialized object to the server.
  But before sending it i need to uppercase all its input elements.</p>
  
  <p>this is a piece of my code:</p>
  
  <pre><code>submitForm: function(e) {
      e.preventDefault();
      var data = Backbone.Syphon.serialize(this);
      console.log(data);// here i need to uppercase all data elements
      this.trigger("form:submit", data);
  },
  </code></pre>
  
  <p>I need to do this before sending it to thserver and not in the backend.
  Any solution to suggest?</p>
