Question

我试图在客户端使用jQuery按日期范围过滤数据，但它没有正确执行，它显示了从2065年开始的数据（虚拟）（链接下面的屏幕截图）。我已经尝试了将近一个星期，但最后看起来我需要一些帮助。

这是我的C＃控制器代码供您检查：

   DateTime StartDate = DateTime.MinValue;
   DateTime EndDate = DateTime.MaxValue;
        if (dateFilter.Contains('~'))
        {
            StartDate = dateFilter.Split('~')[0] == "" ? DateTime.MinValue : Convert.ToDateTime(dateFilter.Split('~')[0]);
            EndDate = dateFilter.Split('~')[1] == "" ? DateTime.MaxValue : Convert.ToDateTime(dateFilter.Split('~')[1]);
        }

        filteredTracks = filteredTracks
             .Where(c => (StartDate == DateTime.MinValue || StartDate <= c.Date)
                                              &&
                         (EndDate == DateTime.MaxValue || c.Date <= EndDate)
        ).OrderByDescending(i => i.Date).ToList();

这里是jQuery客户端供您检查：

var todayDate = new Date();
var endDate = todayDate.getDate() + '/' + (todayDate.getMonth() + 1) + '/' + todayDate.getFullYear();
var d = new Date();
var st = d.setDate(todayDate.getDate() - 75);
var startDate = d.getDate() + '/' + (d.getMonth() + 1) + '/' + d.getFullYear();
$('#startdateadmin-venue').val(startDate);
$('#enddateadmin-venue').val(endDate);

$('#filterStyle-venue').click(function () {
    $("#AdvancedfilterForm-venue").slideToggle(300);
});

$(function () {
    $("#startdateadmin-venue").datepicker({
        dateFormat: 'dd/mm/yy',
        changeMonth: true,
        changeYear: true
    });
});

$(function () {
    $("#enddateadmin-venue").datepicker({
        dateFormat: 'dd/mm/yy',
        changeMonth: true,
        changeYear: true
    });
});

$('#searchrecord-button').click(function (e) {
    e.preventDefault();
    var startDate = $('#startdateadmin-venue').val();
    var endDate = $('#enddateadmin-venue').val();

    $('#myDataTable').dataTable().fnDestroy();

    var oTable = $('#myDataTable').dataTable('load',{
        "oLanguage": {
            "sSearch": " "
        },
        "bAutoWidth": false,
        "sAjaxSource": "AjaxHandler_datesrange",
        "bServerSide": true,
        "bProcessing": false,
        "sScrollY": "333",
        "iDisplayLength": 300,
        "bPaginate": true,
        "bRetrieve": true,
        "bDestroy": true,
        "sPaginationType": "full_numbers",
        "aoColumns": [
    { "mData": "TrackID", "sWidth": "1%" },
    {
        "mData": "Date", "bSortable": false, "sWidth": "1%",
        "fnRender": function (obj, val) {
            var dx = new Date(parseInt(val.substr(6)));
            var dd = dx.getDate();
            var mm = dx.getMonth() + 1;
            var yy = dx.getFullYear();

            if (dd <= 9) {
                dd = "0" + dd;
            }
            if (mm <= 9) {
                mm = "0" + mm;
            }
            return dd + "/" + mm + "/" + yy;
        }
    },
    { "mData": "TrackName", "sWidth": "43%" },
    { "mData": "ArtistName", "sWidth": "30%" },
    { "mData": "Times", "sWidth": "1%" }
        ]
    });      
});

编辑：控制器代码：从Excel文件获取数据：

public static List<TopPlayed> GetTracks()
        {
            if (TrackData == null)
            {
                string Path = @"C:\\5Newwithdate-6r.xls";
                OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= '" + Path + "';Extended Properties=" + (char)34 + "Excel 8.0;IMEX=1;" + (char)34 + "");
                OleDbDataAdapter da = new OleDbDataAdapter("select * from [Sheet1$]", con);
                con.Close();
                System.Data.DataTable data = new System.Data.DataTable();
                da.Fill(data);
                List<TopPlayed> daa = new List<TopPlayed>();
                TrackData = new List<TopPlayed>();
                foreach (DataRow p in data.Rows)
                {
                    TopPlayed top = new TopPlayed()
                    {
                        TrackID = Convert.ToInt32(p.Field<double>("TrackID")),
                        Date = p.Field<DateTime>("DateTimes"),
                        TrackName = p.Field<string>("TrackName"),
                        ArtistName = p.Field<string>("ArtistName"),
                        Times = Convert.ToInt32(p.Field<double>("Times"))
                    };

                    TrackData.Add(top);
                }
            }

            return TrackData;

        }

编辑：控制器代码：过滤：所有过滤功能与日期不同

public ActionResult AjaxHandler_datesrange(jQueryDataTableParamModel param)
    {
        var allTracks = DataRepository.GetTracks();
        IEnumerable<TopPlayed> filteredTracks;

        var dateFilter = Convert.ToString(Request["sSearch_1"]);
        var trackFilter = Convert.ToString(Request["sSearch_2"]);
        var artistFilter = Convert.ToString(Request["sSearch_3"]);

        // Search Filter
        if (!string.IsNullOrEmpty(param.sSearch))
        {
            var isTrackSearchable = Convert.ToBoolean(Request["bSearchable_1"]);
            filteredTracks = DataRepository.GetTracks()
                .Where(c => isTrackSearchable && c.TrackName.ToLower().Contains(param.sSearch.ToLower()));
        }
        else
        {
            filteredTracks = allTracks;
        }

        // Dates
        DateTime StartDate = DateTime.MinValue;
        DateTime EndDate = DateTime.MaxValue;
        if (dateFilter.Contains('~'))
        {
            StartDate = dateFilter.Split('~')[0] == "" ? DateTime.MinValue : Convert.ToDateTime(dateFilter.Split('~')[0]);
            EndDate = dateFilter.Split('~')[1] == "" ? DateTime.MaxValue : Convert.ToDateTime(dateFilter.Split('~')[1]);
        }

        filteredTracks = filteredTracks
             .Where(c => (StartDate == DateTime.MinValue || StartDate <= c.Date)
                                              &&
                         (EndDate == DateTime.MaxValue || c.Date <= EndDate)
        ).OrderByDescending(i => i.Date).ToList();

        // Sorting
        var sortColumnIndex = Convert.ToInt32(Request["iSortCol_0"]);
        var isNameSortable = Convert.ToBoolean(Request["bSortable_1"]);
        var isAddressSortable = Convert.ToBoolean(Request["bSortable_2"]);
        Func<TopPlayed, string> orderingFunction = (c => sortColumnIndex == 1 && isNameSortable ? c.TrackName :
                                                         sortColumnIndex == 2 && isAddressSortable ? c.ArtistName :
                                                         "");
        var sortDirection = Request["sSortDir_0"]; // asc or desc
        if (sortDirection == "asc")
            filteredTracks = filteredTracks.OrderBy(orderingFunction);
        else
            filteredTracks = filteredTracks.OrderByDescending(orderingFunction);

        // Paging
        var displayedTracks = filteredTracks.Skip(param.iDisplayStart).Take(param.iDisplayLength);

        return Json(new
        {
            sEcho = param.sEcho,
            iTotalRecords = allTracks.Count(),
            iTotalDisplayRecords = filteredTracks.Count(),
            aaData = displayedTracks
        },
                    JsonRequestBehavior.AllowGet);
    }

任何帮助都会很棒，谢谢你的时间。

让我们尝试下面的Linq。

DateTime startDate = Model.startdate;
DateTime endDate = Model.enddate;

var queryListOnly = from i in datacontext.yourtable
                     where i.yourdatefield > startDate && i.yourdatefield < endDate
                     select i;

如果您正在使用任何jquery插件，请告诉我，以便我可以提供帮助。

只需使用此

更改日期部分

filteredTracks = filteredTracks.Where(i => i.Date > startDate && i.Date < endDate).tolist();

jQuery按日期范围过滤错误的数据
