【问题描述】：

我的视图提交按钮没有响应。无法调用 [Httppost] 方法请检查下面的代码。当我点击提交时，视图或控制器没有响应。我的 httpGet 和 Httppost 方法同名。

* View



    @model MT566_PSS.Models.EventController

    @{
    ViewBag.Title = "Assign Controller";
    Layout = "~/Views/Shared/_Layout.cshtml";
    }


    @using (Html.BeginForm("EventAssign", "ShowMessage", new { extMsgId = Model.ExternalMessageId, userId = Session["commitId"], currentController = Model.COMMIT_ID }, FormMethod.Post, new { id  = "formPosted1" }))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <div class="BNYMInputBox" id="BlotterSelection">
        <div class="InputBoxHeader">
            <h3>Assign Controller</h3>
        </div>
        <div><span id="postResult"></span></div>
        <div id="inputFields">
            @Html.DropDownListFor(m => m.ID, Model.UserList, "Select", new { @id = "SelectedValue" })


            <input type="submit" value="Submit" id="Submit" />
            @Html.ActionLink("Back to List", "GetExtMsg")
        </div>
    </div>
}




* Controller

  [HttpPost]
        public ActionResult EventAssign(int extMsgId = 0, string userId = "", string currentController = "")
        {
   T_REVIEW_EVENT_ID revent = _dbContext.T_REVIEW_EVENT_ID.FirstOrDefault(x => x.EXT_MSG_ID == extMsgId);
            if (revent != null)
            {
                revent.CTRL_COMMIT_ID = userId;
            }
            _dbContext.SaveChanges();

            var log = new T_LOG
            {
                EXT_MSG_ID = extMsgId,
                COMMIT_ID = userId,
                AFFECTED_DATE = DateTime.Now,
                COMMENTS = currentController + " Changed to:" + userId,
                CHANGED_COLUMN = "Table: " + "T_Review_Event_Id, " + "Column: " + "CTRL_INDICATOR",
                OLD_VALUE = currentController,
                NEW_VALUE = "Controller: " + userId,
                APPLIED_LEVEL = ""
            };
            _dbContext.T_LOG.Add(log);
            _dbContext.SaveChanges();
            ViewData["result"] = "Updated..!!";
            return View("Result");
        }

【问题讨论】：

你是控制器ShowMessageController吗？
确认您的控制器名称并确保您使用的是正确的BeginForm()重载
嗨朋友们，我检查了所有可能的事情，如控制器名称验证、更改视图名称以及模型名称，并尝试创建新视图。但是提交按钮仍然不起作用或没有将控制权转移到 [Httppost] 方法

【解决方案1】：

确保为动作和控制器传递正确的值。根据您的代码，“EventAssign”是您的操作，“ShowMessage”是您的控制器。而不是像这样传递值

    @using (Html.BeginForm("EventAssign", "ShowMessage", new { extMsgId = Model.ExternalMessageId, userId = Session["commitId"], currentController = Model.COMMIT_ID }, FormMethod.Post, new { id  = "formPosted1" }))
    {
      ...........
      ............
    }

您可以使用这样的隐藏字段传递值

    @using (Html.BeginForm("EventAssign", "ShowMessage", FormMethod.Post, new { id  = "formPosted1" }))
    {
        <input type="hidden" name="extMsgId" id="extMsgId" value="@Model.ExternalMessageId"></input>
        <input type="hidden" name="userId" id="userId" value="@Session["commitId"]"></input>
        <input type="hidden" name="currentController" id="currentController" value="@Model.COMMIT_ID"></input>
      ...........
      ............
    }
