Question

在我刚刚继承的该应用程序中单击某个Ajax ActionLink会生成一个POST请求和一个GET请求（POST，然后紧接着是GET）。第一个请求命中服务器上的HttpPost方法，但是第二个请求（GET）在浏览器中引发“ 404（未找到）”错误。如何停止不需要的GET请求？它来自哪里？

如果我将方法从POST更改为GET，则相反的情况是POST引发错误而不是GET。

我在应用程序中搜索了与配置为GET的HttpPost方法类似的请求，但没有。

我搜索了自定义JavaScript，该JavaScript将一个额外的click事件附加到所有链接，但是没有任何实例。可能还会有其他事件在这种情况下产生相同的结果吗？

在DocumentManagementController.cs中：

[HttpPost]
public ActionResult OpenPopup(string ntgLoadId) { ... }

在_GridLoadsAddendum.cshtml中：

@Html.DevExpress().GridView(
settings =>

    settings.Name = "DetailedGrid_" + Model.LoadId;

    settings.Settings.ShowColumnHeaders = false;
    settings.KeyFieldName = "NtgLoadId";

    settings.Columns.Add(column =>
    {
        column.FieldName = "Status";
        column.Caption = "Status";
        column.Width = Unit.Pixel(83);
        column.SetDataItemTemplateContent(c =>
        {
            ViewContext.Writer.Write(
                Ajax.ActionLink(
                    DataBinder.Eval(c.DataItem, "Status").ToString(),
                    "OpenPopup",
                    "DocumentManagement",
                    new
                    {

                    },
                    new AjaxOptions
                    {
                        HttpMethod = "POST",

                        data_Keyboard = "false"
                    }).ToHtmlString());
        });

        Action = "GridLoadsAddendum",
        Id = Model.LoadId
    };
    settings.DataBound = (sender, e) =>
    {
        MVCxGridView gv = sender as MVCxGridView;
        gv.Visible = gv.VisibleRowCount > 0;
    };
}).BindToLINQ(
    string.Empty,
    string.Empty,
    new EventHandler<DevExpress.Data.Linq.LinqServerModeDataSourceSelectEventArgs>(
    (s, e) =>
    {
        e.QueryableSource = Model.CarrierPaymentResultData;
        e.KeyExpression = "ntgLoadId";
    })).GetHtml();

单击Ajax.ActionLink会生成GET和POST
