1. 在更新事件时，手动调用 refetchEvents 方法来刷新事件列表：

@Component({
  selector: 'my-calendar',
  template: `
    
  `
})
class MyCalendarComponent implements OnInit {
  @ViewChild('calendar') calendar: FullCalendarComponent;
  events: any[] = [];

  ngOnInit() {
    this.loadEvents();
  }

  loadEvents() {
    // Load events from server...
    this.events = [...];
    // Manually refresh events
    this.calendar.getApi().refetchEvents();
  }

  handleEventClick(event: any) {
    console.log(event.title);
  }
}

2. 尝试设置 events 属性为一个新的数组引用，而不是在原地修改已有数组。

@Component({
  selector: 'my-calendar',
  template: `
    
  `
})
class MyCalendarComponent implements OnInit {
  @ViewChild('calendar') calendar: FullCalendarComponent;
  events: any[] = [];

  ngOnInit() {
    this.loadEvents();
  }

  loadEvents() {
    // Load events from server...
    const newEvents = [...];
    this.events = newEvents; // Set new reference
  }

  handleEventClick(event: any) {
    console.log(event.title);
  }
}
