我是 Asp.net MVC 的新手，并且在使用以下代码时遇到问题。

  @model SportsStore.Domain.Entities.ShippingDetails

@{
    ViewBag.Title = "SportsStore: Checkout";
}

<h2>Check out now</h2>
Please enter your details and we'll send your goods right away!
@using (Html.BeginForm("Checkout", "Cart"))
{
    @Html.ValidationSummary()

    <h3>Ship to</h3>
    <div>Name: @Html.EditorFor(x => x.Name)</div>

    <h3>Address</h3>
    <div>Line 1: @Html.EditorFor(x => x.Line1)</div>
    <div>Line 2: @Html.EditorFor(x => x.Line2)</div>
    <div>Line 3: @Html.EditorFor(x => x.Line3)</div>
    <div>City: @Html.EditorFor(x => x.City)</div>
    <div>State: @Html.EditorFor(x => x.State)</div>
    <div>Zip: @Html.EditorFor(x => x.Zip)</div>
    <div>Country: @Html.EditorFor(x => x.Country)</div>

    <h3>Options</h3>
    <label>
    @Html.EditorFor(x => x.GiftWrap)
    Gift wrap these items
    </label>


        <p align="center">
            <input class="actionButtons" type="submit" value="Complete order"/>           
        </p>


}

我希望 submit 类型的输入从我的控制器调用 Post version Checkout 操作，如下所示

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using SportsStore.Domain.Abstract;
using SportsStore.Domain.Entities;
using SportsStore.WebUI.Models;

namespace SportsStore.WebUI.Controllers
{
    public class CartController : Controller
    {
        private IProductsRepository repository;
        private IOrderProcessor orderProcessor;

        public CartController(IProductsRepository repo, IOrderProcessor proc)
        {
            repository = repo;
            orderProcessor = proc;
        }

        [HttpPost]
        public ViewResult Checkout(ShippingDetails shippingDetails, Cart cart)
        {
            var test = Request.Form["Line1"];
            if (cart.Lines.Count() == 0)
            {
                ModelState.AddModelError("", "Sorry, your cart is empty!");
            }
            if (ModelState.IsValid)
            {
                orderProcessor.ProcessOrder(cart, shippingDetails);
                cart.Clear();
                return View("Completed");
            }
            else
            {
                return View(shippingDetails);
            }
        }

        public RedirectToRouteResult AddToCart(Cart cart, int productId, string returnUrl)
        {
            Product product = repository.Products.FirstOrDefault(p => p.ProductID == productId);

            if (product != null)
            {
                cart.AddItem(product, 1);
            }

            return RedirectToAction("Index", new { returnUrl });
        }

        public RedirectToRouteResult RemoveFromCart(Cart cart, int productId, string returnUrl)
        {
            Product product = repository.Products.FirstOrDefault(p => p.ProductID == productId);

            if (product != null)
            {
                cart.RemoveLine(product);
            }

            return RedirectToAction("Index", new { returnUrl });
        }

        public ViewResult Index(Cart cart, string returnUrl)
        {
            return View(new CartIndexViewModel { Cart = cart, ReturnUrl = returnUrl });
        }


        public ViewResult Summary(Cart cart)
        {
            return View(cart);
        }

        [HttpGet]
        public ViewResult Checkout()
        {
            return View(new ShippingDetails());
        }

        private Cart GetCart()
        {
            Cart cart = (Cart)Session["Cart"];
            if (cart == null)
            {
                cart = new Cart();
                Session["Cart"] = cart;
            }
            return cart;
        }

    }
}

但是，每当我按下这个输入按钮时，什么都没有发生。

有人可以告诉我有什么问题吗？我认为提交类型的输入按钮会调用该操作的发布版本，但显然这不起作用。

编辑：

我尝试禁用浏览器中的所有 javascript，但这并不能解决问题。

这是我的路由信息​​：

public static void RegisterRoutes(RouteCollection routes)


 {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(null,"", // Only matches the empty URL (i.e. /)
            new
            {
            controller = "Product",
            action = "List",
            category = (string)null,
            page = 1
            }
            );

        routes.MapRoute(null, "Page{page}", new { Controller = "Product", action = "List" });

        routes.MapRoute(null,"{category}", // Matches /Football or /AnythingWithNoSlash
            new { controller = "Product", action = "List", page = 1 });

        routes.MapRoute(null,
        "{category}/Page{page}", // Matches /Football/Page567
        new { controller = "Product", action = "List" }, // Defaults
        new { page = @"\d+" } // Constraints: page must be numerical
        );

        routes.MapRoute(null, "{controller}/{action}");
    }

这是我在 Global.asax 中的 ApplicationStart 方法

protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
        ModelBinders.Binders.Add(typeof(Cart), new CartModelBinder());
    }

我真的不知道还能做什么。如果有人有任何想法，请告诉我。

我希望提交类型的输入从我的控制器调用 Post version Checkout 操作

你为什么期待这样的事情？您似乎没有在您的表格上注明：

@using (Html.BeginForm("Checkout", "Cart"))
{
    ...
}

如果在渲染表单时没有明确指定要调用的操作和控制器名称，那么与渲染此视图的操作相同的操作将使用 HttpPost 调用。因此，例如，如果此视图是从Index操作呈现的，那么如果您使用Html.BeginForm，ASP.NET MVC 将在同一控制器上查找带有 HttpPost 的 Index 操作。

例如：

public ActionResult Index()
{
    ... render the form
}

[HttpPost]
public ActionResult Index(ShippingDetails shippingDetails, Cart cart)
{
    ... process the form submission
}

这就是约定。如果您不想遵循约定，则需要使用 Html.BeginForm 的重载，它允许您指定要调用的操作和控制器。

您必须明确指定要发布表单。默认情况下，它执行 GET。

@using(Html.BeginForm("Checkout", "Cart", FormMethod.Post))
{
    ...
}
