Question

我目前正在尝试通过HTML表单插入模型对象，但是在调试时，它是第二个表作为空对象，即使我指定了输入字段，其名称属性与它们在模型中被调出的方式相匹配。

这是我桌子的edmx图：

我的模特：

 public class TReportHeaderModel
    {

        public int ID { get; set; }
        public int ClientID { get; set; }
        public string  THeaderTitle { get; set; }
        public int RowNumber { get; set; }

        public IList<TReporURLModel> TotalReports { get; set; }


    }


 public class TReporURLModel
    {
        public int ID { get; set; }
        public string  name { get; set; }
        public string url { get; set; }
        public int RowNumber { get; set; }
        public string hash { get; set; }
        //public int THeaderID { get; set; }
    }

这是我的HTML表单作为模式。请忽略JavaScript，因为它是一种演示我在这里尝试实现的表单功能的方法。

但是，我提交表格的ajax如下：

 initCreateGroupForm: function ()
    {
        $('#create-report-group-form').ajaxForm({

            dataType: 'json',
            beforeSerializate: function ($form, options) {

                Reporting.Forms = $form;
            },
            success: function (response) {

                if (response.Success == true) {
                    JQueryUX.Msg.BootStrapShow({
                        msg: response.Message,
                        className: 'alert alert-success',
                        title: 'Report Has Been Created.'
                    });

                    $("#create-report-group-modal").modal('hide');


                }
                else {
                    alert(response.Message);
                }



            },
            onError: function (xhr, status, error)
            {
                alert(error);

            }

        });

$(document).ready(function() {
  $("#add_row").on("click", function() {
    // Dynamic Rows Code

    // Get max row id and set new id
    var newid = 0;
    $.each($("#tab_logic tr"), function() {
      if (parseInt($(this).data("id")) > newid) {
        newid = parseInt($(this).data("id"));
      }
    });
    newid++;

    var tr = $("<tr></tr>", {
      id: "addr" + newid,
      "data-id": newid
    });

    // loop through each td and create new elements with name of newid
    $.each($("#tab_logic tbody tr:nth(0) td"), function() {
      var cur_td = $(this);

      var children = cur_td.children();

      // add new td and element if it has a nane
      if ($(this).data("name") != undefined) {
        var td = $("<td></td>", {
          "data-name": $(cur_td).data("name")
        });

        var c = $(cur_td).find($(children[0]).prop('tagName')).clone().val("");
        c.attr("name", $(cur_td).data("name") + newid);
        c.appendTo($(td));
        td.appendTo($(tr));
      } else {
        var td = $("<td></td>", {
          'text': $('#tab_logic tr').length
        }).appendTo($(tr));
      }
    });

    // add delete button and td
    /*
    $("<td></td>").append(
        $("<button class='btn btn-danger glyphicon glyphicon-remove row-remove'></button>")
            .click(function() {
                $(this).closest("tr").remove();
            })
    ).appendTo($(tr));
    */

    // add the new row
    $(tr).appendTo($('#tab_logic'));

    $(tr).find("td button.row-remove").on("click", function() {
      $(this).closest("tr").remove();
    });
  }); <!--Ends Here-->








  $("#add_row").trigger("click");
});

是否有特定的方法来调用属于第二个表的输入，以便输入可以传递到TReport表而没有任何问题。

因为无论我做什么，它都会以无效方式返回服务。当我调试它时，我将得到第一个表的输入，但没有任何东西会传递给第二个查询，即TReport表。我的服务代码如下：

 public void CreateReport(TReportHeaderModel model)
        {

            using (var connection = new TReportEntitiesConnection())

            {
                connection.THeader.Add(new THeader()
                {
                    ID = model.ID,
                    THeaderTitle = model.THeaderTitle,
                    RowNumber = model.RowNumber


                });

                foreach (var urls in model.TotalReports)
                {

                    connection.TReport.Add(new TReport()
                    {
                        TReportName=urls.name,
                        URL=urls.url


                    });


                }

                connection.SaveChanges();


            }

谢谢！

我清理了一些HTML并重写了一些JavaScript。此代码未经测试，请告诉我它是如何工作的。

$(document).ready(function() {
