如何在angular环境中使用fullcalendar中的控件(特别是eventAllow)来限制某些事件的拖放

npm install fullcalendar @fullcalendar/angular

import { CalendarOptions, EventApi } from '@fullcalendar/angular';
import interactionPlugin from '@fullcalendar/interaction';
import dayGridPlugin from '@fullcalendar/daygrid';

@import '~@fullcalendar/common/main.css';
@import '~@fullcalendar/daygrid/main.css';

export class MyCalendarComponent {
  calendarOptions: CalendarOptions = {
    plugins: [interactionPlugin, dayGridPlugin],
    initialView: 'dayGridMonth',
    events: [
      // 设置日历事件
      { title: 'Event 1', start: '2022-01-01' },
      { title: 'Event 2', start: '2022-01-05' },
      { title: 'Event 3', start: '2022-01-10' }
    ],
    eventAllow: (dropInfo, draggedEvent) => {
      // 通过eventAllow函数来限制事件的拖放
      // 返回true表示允许拖放，返回false表示禁止拖放
      if (draggedEvent.title === 'Event 1') {
        return false; // 禁止拖放标题为"Event 1"的事件
      }
      return true; // 允许拖放其他事件
    }
  };
}

<full-calendar [options]="calendarOptions"></full-calendar>
