Question

我正在尝试使用Visual Studio 2019在Asp.net Core Razor Pages中创建FullCalendar应用程序，但它不显示任何数据。我想单击一个日期，然后在弹出的对话框中输入一个事件。

index.cshtml：

<div style="display:none">
...
<input type="file" id="id_image">
...
</div>

<p class="btn btn-outline-success"
onclick = "document.querySelector('#id_image').click()"
onchange = "this.innerHTML = document.querySelector('#id_image')[0].files[0].name"> 
<i class="someicon"> Image
</p>

Index.cshtml.cs：

  <!DOCTYPE html>

            var calendar = new FullCalendar.Calendar(calendarEl, {

                title = v.Title,
                description = v.Description,
                startdate = v.StartDate.ToString("YYYY-MM-DD"),
                enddate = v.EndDate.ToString("YYYY-MM-DD"),
                themecolor = v.ThemeColor
            }).ToList();
            return new JsonResult(events);
        }
        
    }
}

为什么不显示事件数据？

Answer 1

我对我的应用进行了一些更新。首先，我发现我安装了FullCalendar.io软件的两个不同版本-wwwroot目录中的fullcalendar v.5.3.0和fullcalendar v.4.3.0。因此，我删除了所有这些全日历版本，并从Full Calendar - Getting Started安装了当前版本5.3.2作为Download zip软件包。我手动安装在wwwroot / lib目录下的fullcalendar文件夹中。

我在主项目解决方案的“页面”部分（即Pages / Calendars / index.cshtml）下的“日历”文件夹中创建了一个Razor页面-在主项目区域中创建了index.cshtml，并添加了以下代码（使用脚本标签方法，如此链接中所述-Initialize with Script Tags）：-

@page
@model MyApp.Pages.Calendars.IndexModel
@{
    Layout = null;
}

<!DOCTYPE html>

<html lang='en'>

<head>
    <meta charset='utf-8'/>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <link href='~/lib/fullcalendar/lib/main.css' rel='stylesheet' />    
    <script src='~/lib/fullcalendar/lib/main.js'></script> 

    <script>

         document.addEventListener('DOMContentLoaded', function () {
             var calendarEl = document.getElementById('calendar');
             var calendar = new FullCalendar.Calendar(calendarEl, {
                 initialVeiw: 'dayGridMonth',
                 headerToolbar: {
                     left: 'prev, next today',
                     center: 'title',
                     right: 'dayGridMonth,timeGridWeek,timeGridDay'                    
                 },
             });
             calendar.render();
         });

     </script> 

    </head>
  <body>
    <div id='calendar'></div>
  </body>
</html>
