Question

所需的流程：

用户填写表单
保存表单并提供结果视图
在结果视图中提供一些超链接，提供弹出窗口以创建操作计划
弹出窗口的保存按钮应调用相应的控制器动作
根据弹出式创建成功更新结果视图

问题：保存表单时调用了两个HttpPost操作。

目前的代码：初始表格

 @using (Html.BeginForm())
    {
        @Html.AntiForgeryToken();
...
   var groupItem = settings.Items.AddGroupItem(grpSet =>
   {
       grpSet.ShowCaption = DefaultBoolean.False;
       grpSet.GroupBoxDecoration = GroupBoxDecoration.None;
       grpSet.SettingsItemCaptions.Location = LayoutItemCaptionLocation.Left;
       grpSet.SettingsItemHelpTexts.Position = HelpTextPosition.Auto;
       grpSet.ColCount = 2;
   });

   groupItem.Items.Add(item =>
   {
       item.NestedExtensionType = FormLayoutNestedExtensionItemType.Button;
       item.ShowCaption = DefaultBoolean.False;
       item.ColSpan = 1;
       item.HorizontalAlign = FormLayoutHorizontalAlign.Center;

       var btnSettings = (ButtonSettings)item.NestedExtensionSettings;
       btnSettings.Name = "btnCreate";
       btnSettings.Text = "Finish and save";
       btnSettings.UseSubmitBehavior = true;
       btnSettings.RouteValues = new { Controller = "General", Action = "A_General", completed = true };

   });
}

弹出窗口的结果视图：

 <div> Display result
@Html.DevExpress().HyperLink(hl =>
                        {
                            hl.Name = "createAP" ;
                            hl.NavigateUrl = "javascript:void(0)";
                            hl.Properties.ClientSideEvents.Click = "function (s, e) { pcCreateAP.PerformCallback(); pcCreateAP.Show(); }";
                            hl.Properties.ImageUrl = "~/Images/AddFile_16x16.png";
                            hl.Attributes.Add("title", "Create AP");
                        }).GetHtml()
 </div>

@Html.DevExpress().PopupControl(settings =>
{
    settings.Name = "pcCreateAP";
    settings.Width = 700;
    settings.AllowResize = true;
    settings.AllowDragging = true;
    settings.CloseAction = CloseAction.CloseButton;
    settings.CloseOnEscape = true;
    settings.PopupAnimationType = AnimationType.Fade;
    settings.HeaderText = "Create Health Action Plan";
    settings.Modal = true;
    settings.PopupHorizontalAlign = PopupHorizontalAlign.WindowCenter;
    settings.PopupVerticalAlign = PopupVerticalAlign.TopSides;
    settings.SetContent(() =>
    {
        Html.Action("CreateAP", "AP", null);
    });
}).GetHtml()

弹出窗口的cshtml也包含

Html.DevExpress().Button(btnSet =>
    {
        btnSet.Name = "btnCreateAp";
        btnSet.ControlStyle.CssClass = "button";
        btnSet.Width = Unit.Percentage(100);
        btnSet.RouteValues = new { Controller = "AP", Action = "CreateAP" };
        btnSet.Text = "Create";
        btnSet.UseSubmitBehavior = true;
    }).GetHtml();

这两个动作都得到了[HttpPost，ValidateAntiForgeryToken]装饰。我不知道它是DevExpress问题还是一些基本的HTML ......

Answer 1

您应该尝试在代码的第一行显式指定Controller和Action Method。

@using (Html.BeginForm())替换为

@using (Html.BeginForm("YourAction", "YourController", FormMethod.Post))
{

}

Answer 2

解决方案是使用与控制器中的get函数不同的名称。在我的情况下，我刚刚将它重命名为CreateAPSave，现在保存初始表单时不会调用它。

提交按钮调用所有HttpPost
