ASP.NET MVC中对fullcalendar的CRUD操作



我对fullcalendar和ASP.NET MVC有问题。我将格式日期设置为"YYYY/MM/DD"，但当我尝试保存事件时，JS或C#(我不太确定)会自动将格式更改为"YYYY/DD/MM"。结果是，当我选择日期等于或大于13时，我会得到异常"将datetime2数据类型转换为datetime数据类型导致值超出范围"，并且总是得到类似"[000001-01-01]"的日期。

我尝试过以不同的方式更改View中的日期格式，但没有任何积极的结果。

我想要从这个站点实现代码：http://www.dotnetawesome.com/2017/07/curd-operation-on-fullcalendar-in-aspnet-mvc.html

在我的项目中，但它不适用于日期。但当我从网站下载这个项目并打开时，一切都很好，我不知道我的项目出了什么问题。

你有什么想法吗？

如果有任何答复，我将不胜感激。

我的控制器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVCEventCalendar.Controllers
{
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
public JsonResult GetEvents()
{
using (MyDatabaseEntities dc = new MyDatabaseEntities())
{
dc.Configuration.LazyLoadingEnabled = false;
var events = dc.Events.ToList();
return new JsonResult { Data = events, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
}
[HttpPost]
public JsonResult SaveEvent(Event e)
{
var status = false;
using (MyDatabaseEntities dc = new MyDatabaseEntities())
{
if (e.EventID > 0)
{
//Update the event
var v = dc.Events.Where(a => a.EventID == e.EventID).FirstOrDefault();
if (v != null)
{
v.Subject = e.Subject;
v.Start = e.Start;
v.End = e.End;
v.Description = e.Description;
v.IsFullDay = e.IsFullDay;
v.ThemeColor = e.ThemeColor;
}

else

dc.Events.Add(e);

if (v != null)
{
dc.Events.Remove(v);
dc.SaveChanges();
status = true;
}
}
return new JsonResult { Data = new { status = status} };
}
}
}

型号：

namespace School_Project.Models
{
using System;
using System.Collections.Generic;
public partial class Events
{
public int EventID { get; set; }
public int ClassID { get; set; }
public string Subject { get; set; }
public string Description { get; set; }
public System.DateTime Start { get; set; }
public Nullable<System.DateTime> End { get; set; }
public string ThemeColor { get; set; }
public bool IsFullDay { get; set; }
public virtual School_Class School_Class { get; set; }
}
}

在问题中，您说

"我将格式日期设置为'YYYY/MM/DD'"。

然而，从代码中可以清楚地看出，这不是真的。在示例中的每个实例中，都以DD/MM/YYYY格式输出日期，这可能是不明确的(正如您所发现的，可能会混淆日期和月份)。此外，格式字符串中的"A"(用于输出AM/PM)也没有意义，因为HH:mm已经以24小时格式输出了时间。所以我并不奇怪服务器会对你的意思感到困惑。

您应该使用一种明确的格式，服务器不可能对其进行错误解释。ISO-8601格式是公认的标准。momentJS提供了一种称为toISOString()的现成方法，用于以这种格式输出：

event.start.toISOString();

请参阅https://momentjs.com/docs/#/displaying/as-iso字符串/获取更多详细信息。

另一件需要注意的事情是，根据fullCalendar文档，你的库，包括momentJS(处理日期)，已经过时了：https://fullcalendar.io/support.您需要jQuery 2或以上，以及momentJS 2.9或以上

对不起，我写这篇文章很晚了。但我找到了解决办法！

首先，当我想保存我的表格：

function openAddEditForm() {
if (selectedEvent != null) {
$('#hdEventID').val(selectedEvent.eventID);
$('#txtSubject').val(selectedEvent.title);
$('#txtStart').val(selectedEvent.start.format('DD-MM-YYYY HH:mm'));
$('#chkIsFullDay').prop("checked", selectedEvent.allDay || false);
$('#chkIsFullDay').change();
$('#txtEnd').val(selectedEvent.end != null ? selectedEvent.end.format('DD-MM-YYYY HH:mm') : '');
$('#txtDescription').val(selectedEvent.description);
$('#ddThemeColor').val(selectedEvent.color);
}

$('#myModal').modal('hide');
$('#myModalSave').modal();
}

然后我在日期格式上遇到了一些问题，因为C#只理解像"MM-DD-YYYY HH:MM"这样的格式，但我希望显示"DD-MM-YYYY HH:MM"。

所以我只是简单地改变了日期元素的位置。

var format_start = $('#txtStart').val().replace(' ', '-').split('-');
var nowy_start = format_start[1] + '-' + format_start[0] + '-' + format_start[2] + ' ' + format_start[3];
var format_end = $('#txtEnd').val().replace(' ', '-').split('-');
var nowy_end = format_end[1] + '-' + format_end[0] + '-' + format_end[2] + ' ' + format_end[3];
var data = {
EventID: $('#hdEventID').val(),
Subject: $('#txtSubject').val().trim(),
Start: nowy_start.trim(),
End: $('#chkIsFullDay').is(':checked') ? null : nowy_end.trim(),
Description: $('#txtDescription').val(),
ThemeColor: $('#ddThemeColor').val(),
IsFullDay: $('#chkIsFullDay').is(':checked'),
ClassID: $('#ddClassID').val()
}
SaveEvent(data);

现在一切都如我所愿。

我有一个建议给你：

转到文件：Web.Config，在第18行添加这行代码：

<globalization culture="en-GB" uiCulture="en-GB"/>

这将帮助您使用组件完整日历处理时间和日期
