Question

In my razor view, I’m using a Html.BeginForm. In it I have two elements where when I set clic, should submit the form but I need to add an additional string parameter.

@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");
        }
    }

So, in my jquery function I utilize $("#element").submit() and the parameter parameter always is null (and that’s normal). How can I add additional data for parameter using JQUERY?

NOTE: I’m not using AJAX.

On your form sumbit try like this:

        $("form").submit(function(){
           $.ajax({     
                type: 'POST',  
                url: "/Quiz/Index",
                dataType: "json",
                data: $("form").serialize() + '&parameter=param1' ,   
                success: function () { 
                    alert("Successful"); 
                }
                error: function(){
                    alert('error');
                }

            }); 
        });

Hope it helps.

Edit

Try like this in your jQuery function:

$('form').append('&param=a');
