Question

我查看了哪个名称是感谢，我想在点击提交后显示此视图，但遇到错误如下：无法找到网页这是我的代码：

 public class HomeController : Controller
    {
        public ViewResult Index()
        {
            int hour = DateTime.Now.Hour;
            ViewBag.greeting = hour < 12 ? "Good Morning" : "Good Afternoon";
            return View ("MyView");
        }
        [HttpGet]
        public ViewResult RsvpForm()
        {
            return View("RsvpForm");

        }
        [HttpPost]

        public ViewResult RsvpForm(GuestRespons GuestRespons)
        {
            Repository.AddResponse(GuestRespons);
            return View("Thanks", GuestRespons);

        }

    }

这是我的观点：

@{Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>
        Thanks
    </title>
</head>
<body>
    <p>
        <h1>
            thank you,@Model.Name!
        </h1>

        @if (Model.WillAttend== true)
        {
            @:it's great that you are comming.we will see you soon.
        }
        else
    {
        @:Sorry to hear that, but Thanks for letting us to know.     
    }
    </p>
    <p >
        click <a asp-action="ListResponses">here</a> to see who is coming.
    </p> 
</body>
</html>

这个是我的按钮，应该显示感谢视图：

@model FuturGoals_partyinvites_.Models.GuestRespons


@{
    Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>RsvpForm</title>
</head>
<body>
    <form asp-action="RcvpForm" method="post">

        <p>
            <label asp-for="Name">Your Name:</label>
            <input asp-for="Name" />
        </p>
        <p>
            <label asp-for="Email">Your Email:</label>
            <input asp-for="Email" />
        </p>
        <p>
            <label asp-for="phone">Your Phone:</label>
            <input asp-for="phone" />
        </p>
        <p>
            <label>Will you come?</label>
            <select asp="WillAttend">
                <option value="">Choose an option</option>
                <option value="true">Yes</option>
                <option value="false">No</option>
            </select>
        </p>
        <button type="submit">Submit RSVP</button>
    </form>
</body>
</html>

好吧，我不知道如何在mvc中获得异常，我认为问题应该在这一行：

<button type="submit">Submit RSVP</button>

提前致谢。

Answer 1

您的表单操作属性值应该是您应用中的有效网址。如果您使用的是表单标记帮助程序，则需要确保将要提交的有效HttpPost操作方法名称作为asp-action属性值传递。

在您的情况下，您的http发布操作方法名称为RsvpForm，但在您的表单中，您有RcvpForm这不是有效的操作方法。因此，修复表单标记帮助程序以使用正确的操作方法，现在它应该可以正常工作。

<form asp-action="RsvpForm" method="post">
   <!-- Your existing form elements goes here-->
</form>

做类似的事情：

    <p>
        <label asp-for="Name">Your Name:</label>
        <input asp-for="Name" />
    </p>
    <p>
        <label asp-for="Email">Your Email:</label>
        <input asp-for="Email" />
    </p>
    <p>
        <label asp-for="phone">Your Phone:</label>
        <input asp-for="phone" />
    </p>
    <p>
        <label>Will you come?</label>
        <select asp="WillAttend">
            <option value="">Choose an option</option>
            <option value="true">Yes</option>
            <option value="false">No</option>
        </select>
    </p>
    <button type="Button" id="submitme" data-url="@Url.Action("RsvpForm","Home")">Submit RSVP</button>

Ajax形式如：

    $("#submitme").on("click", function () {

      var url = $(this).data('url');

       $.ajax({
                            type: 'post',//this can be change to get or post
                            url: url,
                            success: function (response) {
                                if (response != null && response.success) {
                                   Alert("Success");

                                    window.location.href = "/Home/ActionNameHere"; //You can redirect any action name here....
                                } else {
                                    // DoSomethingElse()

                                      Alert("something wrong");

                                }
                            }
                        });

    });

提交我的信息后无法找到该网页
