ASP.NET MVC AJAX发布到控制器操作不起作用

Question

在我的ASP.NET MVC 4视图中,以下内容不是调用控制器操作.Click事件会触发,因为我可以看到警报消息.但是当我在调试模式下对控制器动作设置断点时,应用程序无法达到这一点,当我在警报消息上单击"确定"时没有任何反应.我正在使用LINQ to SQL.类似的保存和插入控制器操作的调用工作正常:

$('#DeletePOC').click(function () {
                if (confirm("This action will delete this POC record permanently. Click OK if you want to delete this record; otherwise, click 'Cancel'")) {
                    disableButton(['#CancelPOC', '#POC']);
                    $.ajax({
                        url: '@Url.Action("POCDelete")', type: "POST", dataType: "json",
                        data: {
                            SitePOCID: $('#POCId').val()
                        },
                        success: function (data) {
                            $('#POCStatus').html('<div class="success">POC Removed Successfully.</div>');
                        },
                        error: function () {
                            $('#POCStatus').html('<div class="field-validation-error">Some Error Occured in Removing POC.</div>');
                        }
                    });
                }
            });

控制器:我在调试期间测试过,app没有达到这个操作方法:

[HttpPost]
public ActionResult POCDelete(int id)
{
   db.POC_dsp(id);
   return Json("");
}

您应该提供与函数参数相同的数据.在您的情况下,您的数据名称应为id(而不是SitePocId)

$('#DeletePOC').click(function () {
            if (confirm("This action will delete this POC record permanently. Click OK if you want to delete this record; otherwise, click 'Cancel'")) {
                disableButton(['#CancelPOC', '#POC']);
                $.ajax({
                    url: '@Url.Action("POCDelete")', type: "POST", dataType: "json",
                    data: {
                        id: $('#POCId').val()
                    },
                    success: function (data) {
                        $('#POCStatus').html('<div class="success">POC Removed Successfully.</div>');
                    },
                    error: function () {
                        $('#POCStatus').html('<div class="field-validation-error">Some Error Occured in Removing POC.</div>');
                    }
                });
            }
        });
