Question

我正在尝试从记录列表中删除一条记录。之前工作正常。现在，当我在ajax函数中按Delete时，它将引发异常“已添加具有相同键的项。”

我已经尝试过从有关此主题的已回答问题中选择一些方法，但是我无法解决我的问题。我无法找出我的代码中重复的名称或其他重复的实体/变量的位置。

HTML


 <td>
    <div class="hidden-phone visible-desktop btn-group">
        <a href="@Url.Content("~/backend/Car/UpdateUsedCar/")@CryptoProvider.Encrypt(Car.Id)" class="btn btn-mini btn-info" title="Edit Car"><i class="icon-edit"></i></a>

        </div>
    </div>
</td>

jQuery函数以确认删除

function deleteConfirmation(link) {
    debugger;
    var index = $(link).parent().parent().parent().index();

    $('.deleteThisRecord').removeClass('deleteThisRecord'); // Unselect All
    $(link).addClass('deleteThisRecord');

    var message = GetMessageBox(confirmHeading, deleteMessage, true);
    $('#dataConfirmModal').remove();
    $('body').append(message);
    //if (!$('#dataConfirmModal').length) {
    //    $('body').append(message);
    //}
    $('#dataConfirmModal').find('.modal-body').text($(link).attr('data-confirm'));
    $('#dataConfirmOK').attr('onclick', 'javascript:ajaxDeletion(' + index + ');');
    $('#dataConfirmModal').modal({ show: true });
    return false;
}

function ajaxDeletion(pos) {
    debugger;
    //var url = $('tbody').children('tr').eq(pos).find('.icon-trash').parent().attr('href');
    //var ico = $('tbody').children('tr').eq(pos).find('.icon-trash');
    //var tr = $('tbody').children('tr').eq(pos);
    //var row = $(ico).closest('tr');
    var url = $('.deleteThisRecord').attr('href');
    var row = $('.deleteThisRecord').parents('tr').eq(0);
    var nRow = row[0];
    $.ajax({
        url: url,
        type: "POST",
        dataType: "json",
        success: function (data, status) {
            debugger;
            if (data.status == 'success') {
                //oTable.fnDeleteRow(pos);
                //var table1 = $('tbody').parent();
                //alert(tabl1);
                //table1.deleteRow(pos);
                //while (table && table.tagName != 'TABLE')
                //    table = table.parentNode;
                //if (!table)
                //    return;
                //table.deleteRow(row.rowIndex);
                oTable.fnDeleteRow(nRow);
                $('#dataConfirmLabel').html(successHeading);
                $('.modal-body').html(data.message);
                VerifyTable();

            } else {
                debugger;
                $('#dataConfirmLabel').html(failedHeading);
                $('.modal-body').html(data.message);
            }

            debugger;
            $('#btnDialogCancel').hide();
            $('#dataConfirmOK').attr('onclick', '');
            $('#dataConfirmOK').attr('onclick', "$('.close').click();");

        },
        error: function (data, status) {
            debugger;
            //console.log(data);
            //alert(" Can't do because: " + error);
        }
    });
    return false;
}

控制器中的功能

 public ActionResult DeleteUsed(KapCarViewModel model)
        {
delete record
}

用于从前端解密加密值的功能

public bool ContainsPrefix(string prefix) {
            try {
                if (_routeData.Values[prefix] == null || !prefix.ToLower().Equals("id") || _id > 0 || Convert.ToString(_routeData.Values["controller"]) == "Home" ) {
                    return false;
                }
                _routeData.Values[prefix] = CryptoProvider.Decrypt(_routeData.Values[prefix].ToString());
                _id = Convert.ToInt32(_routeData.Values[prefix]);
                return true;
            }
            catch (Exception)
            {
                throw new Exception("Invalid request found.");
            }
            return false;
        }

查看模型以获取/设置值

public class KapCarViewModel : BaseViewModel
    {
        public int Id { get; set; }
        public string EncryptedId { get; set; }
    }

我需要在用户确认对话框中的“确定”后删除记录。但是“已经添加了具有相同键的项目。”此错误不允许我这样做。我没有从头开始编写此代码，但以前运行良好。突然，它停止工作了。请指导我解决这个问题。注意：当此代码从前端解密记录ID值时。解密函数然后访问引发错误的视图模型

具有相同键的项已添加-AJAX-jQuery
