title: How to add additional data in my JQUERY submit?
body: <p>In my razor view, I'm using a <code>Html.BeginForm</code>. In it I have two elements where when I set clic, should submit the form but I need to add an additional string parameter.</p>
  
  <pre><code>@using (Html.BeginForm("Index", "Quiz", FormMethod.Post, new { id = "form" }))
  {
      ...
  }
  
      [HttpPost]
      public ActionResult Index(string parameter, QuizCompletedViewModel q)  //FormCollection f)
      {            
          ...
          if (button.Equals("d"))
          {
              ...
              return RedirectToAction("ShowResults", new { testId = Quiz.QuizId, answeredTest = answeredId });
          }
          else
          {
              ...
              return RedirectToAction("Index", "Dashboard");
          }
      }
  </code></pre>
  
  <p>So, in my jquery function I utilize <code>$("#element").submit()</code> and the parameter <code>parameter</code> always is null (and that's normal). How can I add additional data for <code>parameter</code> using JQUERY?</p>
  
  <p>NOTE: I'm not using AJAX.</p>
