无法读取未定义的属性(读取 'formatDate')

Cannot read properties of undefined (reading 'formatDate')

我的代码有什么问题?

Cannot read properties of undefined (reading 'formatDate')

 editable:true,
    eventResize:function(event)
    {
    console.log(event.start);
    
     var start = $.fullCalendar.formatDate(event.start, "YYYY-MM-DD HH:mm:ss");
     var end = $.fullCalendar.formatDate(event.end, "YYYY-MM-DD HH:mm:ss");
     var title = event.title;
     var id = event.id;
     $.ajax({
      url:"../Components/calendar/update.php",
      type:"POST",
      data:{title:title, start:start, end:end, id:id},
      success:function(){
       calendar.fullCalendar('refetchEvents');
       alert('Event Update');
      }
     })
    }

Console.log 个 event.start

这是旧版本

$.fullCalendar.formatDate(event.start, "Y-MM-DD HH:mm:ss");

解决方案:

moment(event.start, 'DD.MM.YYYY').format('YYYY-MM-DD HH:mm:ss')

当您 select 完整日历上的开始和结束日期也使用以下代码时:

select: function(start, end) {
                  
     var start_date = moment(start).format('YYYY-MM-DD HH:mm:ss'));
     var end_date = moment(end).format('YYYY-MM-DD HH:mm:ss'));
