javascript - ASP.NET 表单不提交

Question

当我点击提交时，页面被刷新，看起来一切都已完成，但没有到达我试图将其发送到的 ActionResult。

我试过正常提交和使用 JavaScript，但都不起作用。

<form method="post" autocomplete="off" asp-controller="Default" asp-action="Submit">
    <button id="SubmitButton" type="submit">Submit</button>
</form>

Controller 方法:

namespace (Removed).Controllers
{
    public class DefaultController : Controller
    {
        [HttpPost]
        public ActionResult Submit()
        {
            DBController1 DB1 = new DBController1();
            AlertManagement am = new AlertManagement();

            am.FirstName = Request.Form["FirstName"];
            am.LastName = Request.Form["LastName"];
            am.Email = Request.Form["EmailAddress"];
            am.Mobile = Request.Form["PhoneNumber"].Replace("(", "").Replace(")", "").Replace(" ", "").Replace("-", "");
            am.Affiliation = Request.Form["Affiliation"];
            am.StartDate = Convert.ToDateTime(Request.Form["StartDate"]).Date;
            am.EndDate = Convert.ToDateTime(Request.Form["EndDate"]).Date;

            DB1.AlertManagement.Add(am);
            DB1.SaveChanges();

            return RedirectToAction("Index");
        }

        public ActionResult Index()
        {
            return View();
        }
    }
}

这是路由配置:

namespace (Removed)
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Index",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
            );

            routes.MapRoute(
                name: "Submit",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Default", action = "Submit", id = UrlParameter.Optional }
            );
        }
    }
}

当我点击提交时，它总是转到 ActionResult Index()

Answer 1

这里是在黑暗中拍摄的，但是您的 Controller 看起来像这样吗？

public class DefaultController: Controller
    {
        [HttpPost] // This attribute states that this action result can only be accessed when using http POST verb.
        public IActionResult Submit()
        {
            return RedirectToAction("index", "home");
        }

    }

此外，您发布的是什么？如果您在示例中故意遗漏了这些字段，请确保在您的 POST 方法中有这个。

<form method="post" autocomplete="off" asp-controller="Default" asp-action="Submit">
<input type="text" name="nameOfElement" id="clientName" />
    <button id="SubmitButton" type="submit">Submit</button>
</form>
    public class DefaultController: Controller
            {
                [HttpPost] 
                public IActionResult Submit([FromForm] string nameOfElement)
                {
                    return RedirectToAction("index", "home");
                }

            }
