问题描述

ASP.NET MVC2观点：

ASP.NET MVC2 view:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcMusicStore.ViewModels.PaymentViewModel>" %>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    ...
    <form action="<%= Html.Action("PaymentByBankTransfer", "Checkout") %>" >
    <input type="submit" value="Payment by bank transfer" />
    </form>

CheckoutController：

CheckoutController:

    public ActionResult PaymentByBankTransfer()
    {
        var order = Session["Order"] as Order;
        ExecCommand(@"update dok set confirmed=true where order={0}", order.OrderId);
        return CheckoutCompleteOK();

        var cart = ShoppingCart.GetCart(HttpContext);
        cart.EmptyCart();
        // http://stackoverflow.com/questions/1538523/how-to-get-an-asp-net-mvc-ajax-response-to-redirect-to-new-page-instead-of-inser?lq=1
        return JavaScript("window.location = '/Checkout/CompleteOK'");
    }

    // common method called from other controller methods also
    public ActionResult CheckoutCompleteOK()
    {
        var cart = ShoppingCart.GetCart(HttpContext);
        cart.EmptyCart();
        // prevent duplicate submit if user presses F5
        return RedirectToAction("Complete");
    }

   public ActionResult Complete()
    {
        var order = Session["Order"] as Order;
        SendConfirmation(order);
        return View("PaymentComplete", order);
     }

<一个href="http://stackoverflow.com/questions/1538523/how-to-get-an-asp-net-mvc-ajax-response-to-redirect-to-new-page-instead-of-inser?lq=1">How得到一个ASP.NET MVC Ajax响应重定向而不是插入视图到UpdateTargetId？

时，试图修复它，但是这会导致其他错误：浏览器尝试打开网址了window.location ='/结帐/ CompleteOK

is tried to fix it, but this causes other error: browser tries to open url window.location = '/Checkout/CompleteOK'

如何解决这一例外？一切看起来都OK，还有在其他的答案中所述任何部分景色。 我试过ALS O操作使用方法='后'的形式，但问题仍然存在属性。

How to fix this exception? Everything looks OK, there is no partial views as described in other answers. I tried als o to use method='post' attribute in form but problem persists.

推荐答案

而不是调用的公众的ActionResult CheckoutCompleteOK（）的帖子，删除操作，并创建一个HTTP POST操作为公众的ActionResult PaymentByBankTransfer（）。

Instead of Calling public ActionResult CheckoutCompleteOK() on post, remove that action and Create a HTTP Post Action for public ActionResult PaymentByBankTransfer().

然后返回 RedirectToAction（完整）; 在PaymentByBankTransfer POST方法

Then return RedirectToAction("Complete"); in PaymentByBankTransfer post method.

我认为这将解决您的问题。

I think this would solve your problem.
