如果你不绝对需要向导页上AJAX，可以通过一个成功的表单POST之后返回不同的视图来做到这一点。

If you don't absolutely need AJAX on the wizard page, it is possible to do this by returning different views after a successful form POST.

在控制器：

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult DoSomethingLong(int somethingId, int step)
{
  MyModelType myModel = MyModelFactory.Fetch(somethingId);

  switch(step)
  {
    case 1:
      return View("Step1", myModel);
      break;
    case 2:
      return View("Step2", myModel);
      break;
  }
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DoSomethingLong(int somethingId, int step)
{
   MyModelType myModel = MyModelFactory.Fetch(somethingId);

   if (TryUpdateModel(myModel))
   {
       //Successful update.  Send to next step.
       return RedirectToAction("DoSomethingLong", new {somethingId = somethingId, step = step + 1}
   }
   else
   {
       //Update failed, redisplay current View with validation errors.
       return View(myModel);
   }
}
