如何解决FullCalendar不显示数据asp.net核心剃须刀页面
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>

为什么不显示事件数据？
控制台窗口显示以下错误消息（请参阅随附的两个屏幕截图）：-
解决方法
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>
Visual Studio中的输出解决方案如下所示：-
