call FormMethod.Post from javascript asp.net mvc 4

Question

I am having a problem in getting a fileupload on clicking a link on my navigation bar.

I am using mvc 4 and have a controller that loads the file in and checks it is ok, i can get this done through a input method but it doesn't look nice and want to make the UI a bit slicker so what i have is a link button called upload. what i want to do is call the FormMethod.post with the required upload details. I am very new to this so forgive me if its a simple question.

<li><a href="#" onclick="fileUpload()">upload</a></li>

this works

@using (Html.BeginForm("Upload", "Authenticated", FormMethod.Post, new { enctype = "multipart/form-data" }))
 {
    @Html.ValidationSummary(true)
      <fieldset>
         Select a file : <input type="file" name="file" />
         <input type="submit" value="Upload" />
      </fieldset>
 }

Finally got this to work I needed to add <input type="file" name="file" hidden="true" onchange='this.form.submit();'/> and this allowed it to fire the item off.

Thanks for the tips @David.
