Question

我是jquery新手。我想从控制器返回一个值到视图。所以我用viewBag。我尝试逐步向您展示我的所有代码。
我不明白为什么会收到此错误。

这是我的控制器代码：

 public ActionResult Index(string accountIdFilter,string dateFilter, int page=1, Sort sortOrder =Sort.Descending)        
        {
            int take = 2;
            ViewBag.CurrentSort = sortOrder;
            ViewBag.NameSortParm = sortOrder == Sort.Descending ? Sort.Assending : Sort.Descending;
            ViewBag.AccountIdFilter = accountIdFilter;                       
            DateTime? _dateFilter;
            if (dateFilter==null)
            {
                _dateFilter = null;
            }
            else
            {
                long epoch = Convert.ToInt64(dateFilter);
                _dateFilter = GetEpoch.FromUnixTime(epoch); 
            }                       
            ViewBag.Date = dateFilter;
            BankDepositHistoryListDTO data;
            try
            {                
                 data = BankDepositHistoryServices.GetAllByPagination(sortOrder, accountIdFilter, take, _dateFilter, page);                
            }
            catch (Exception ex)
            {
                logger.Error(ex.ToString());
                data = BankDepositHistoryServices.GetAllByPagination(sortOrder, accountIdFilter, take, _dateFilter, 1);
                page = 1;
            }
            var result = data.BankDepositHistoriyItems;
            int count = data.Count;
            var resultPagedList = new StaticPagedList<BankDepositHistoryDTO>(result, page, take, count);
            return View(resultPagedList);            
        }

主要部分在这里：

ViewBag.Date = dateFilter;

现在我想在我定义视图的输入中得到它。所以我这样做了：

@using (Html.BeginForm())
{
    <p>
        Find by name: @Html.TextBox("AccountIdFilter", ViewBag.AccountIdFilter as string, new { @Id= "accountIdFilter"})
        From date: <input type="text"  class="initial-value-type-gregorian-example" id="DateTime" autocomplete="off"  />
        <input type="hidden" id="customInput" data-value="@ViewBag.Date" />
        <input type="submit" value="Search" />
        </p>
}
  @section scripts
            {                           

                <script type="text/javascript" >
                    var datefilter  = $("#customInput").data("value");                    
                    debugger
                    $(document).ready(function () {                       
                        console.log("ready!");
                        $('.initial-value-type-gregorian-example')
                            .persianDatepicker({
                                initialValueType: 'gregorian',
                                locale: 'en',
                                format:'LLLL',
                                toolbox: {
                                    submitButton: {
                                        enabled: true
                                    },
                                    calendarSwitch: {
                                        enabled: true
                                    }
                                },
                                onSelect: function (unix) {
                                    datefilter = unix;
                                    console.log('datepicker select : ' + unix);
                                }
                            })
                        if (datefilter == null) {
                            debugger
                            $("#DateTime").val(null);                            
                        }
                        else {
                            debugger 
                            $("#DateTime").val(new persianDate.unix(datefilter));                            
                        }                                                    
                    });

                    $("form").submit(function () {
                        if (datefilter == null) {
                            window.location.href = "/?accountIdFilter=" + $("#accountIdFilter").val()
                            debugger
                        }
                        else
                        {
                            window.location.href = "/?dateFilter=" + datefilter + "&accountIdFilter=" + $("#accountIdFilter").val()
                            debugger
                        }
                        console.log("we are in func")
                        debugger
                        return false;
                    });
                </script>
            }

主要部分在这里：

     var datefilter  = $("#customInput").data("value");  
 if (datefilter == null) {
                            window.location.href = "/?accountIdFilter=" + $("#accountIdFilter").val()
                            debugger
                        }
                        else
                        {
                            window.location.href = "/?dateFilter=" + datefilter + "&accountIdFilter=" + $("#accountIdFilter").val()
                            debugger
                        }

我希望得到null或值，但是我在输入中得到了这个值：[object Object]

Answer 1

将隐藏的输入更改为此：

@Html.Hidden("customInput", (object)ViewBag.Date.ToString("dd.MM.yyyy"), new { @id = "customInput" })

并像这样取它的值：

var myvar = $("#customInput").val();

我在输入中遇到Object对象的原因是什么？
