angular - 如何从此 PrimeNG FullCalendar 动态删除事件（单击事件）？

问题描述

我正在使用 PrimeNG Full Calendar 组件开发一个 Angular 应用程序，这个：https ://primefaces.org/primeng/showcase/#/fullcalendar

这是基于 Angular FullCalendar 组件，这个：https ://fullcalendar.io/

在这里你可以找到我的整个代码：https ://bitbucket.org/dgs_poste_team/soc_calendar/src/master/

所以我有一个这样的日历：

我在这个阶段试图实现的是，当用户点击一个特定的事件时，这个日历中的所有事件都将被删除（在第二阶段，我将实现只删除特定的点击事件，但在时刻我保持逻辑尽可能简单）。

所以这是控制我的日历组件的类：

import { Component, OnInit, ViewChild, ElementRef } from '@angular/core';
import { EventService } from '../event.service';
import dayGridPlugin from '@fullcalendar/daygrid';
import timeGridPlugin from '@fullcalendar/timegrid';
import listPlugin from '@fullcalendar/list';
import interactionPlugin, { Draggable } from '@fullcalendar/interaction';
import { FullCalendar } from 'primeng';

@Component({
  selector: 'app-fullcalendar',
  templateUrl: './fullcalendar.component.html',
  styleUrls: ['./fullcalendar.component.css']
})
export class FullcalendarComponent implements OnInit {

  events: any[];
  options: any;
  header: any;

  //people: any[];

  @ViewChild('fullcalendar') fullcalendar: FullCalendar;

  calendar:any;


  constructor(private eventService: EventService) {}

  ngOnInit() {
    //this.eventService.getEvents().then(events => { this.events = events;});

    this.eventService.getEvents().subscribe(events => { this.events = events.map((event) => {
      var date = new Date(event.start);
      var hour = date.getHours();
      //event['backgroundColor'] = hour === 7? 'red': (hour === 7 ? 'green' : 'black');

      //let events = this.calendar.getEvents();
      //events[

      console.log("EVENTS: " + this.events);

      if(hour === 7) {
        event['backgroundColor'] = 'red';
      }
      else if(hour === 15) {
        event['backgroundColor'] = 'green';
      }
      else if(hour === 23) {
        event['backgroundColor'] = 'black';
      }


      return event;
    })});

    this.options = {
        plugins:[ dayGridPlugin, timeGridPlugin, interactionPlugin, listPlugin ],
        defaultDate: '2017-02-01',
        header: {
            left: 'prev,next',
            center: 'title',
            right: 'dayGridMonth,timeGridWeek,timeGridDay'
        },
        editable: true,
        nextDayThreshold: '09:00:00',
        allDayDefault: false,

        dateClick: (dateClickEvent) =>  {         // <-- add the callback here as one of the properties of `options`
          console.log("DATE CLICKED !!!");
        },

        eventClick: (eventClickEvent) => {
          console.log("EVENT CLICKED !!!");
          console.log(eventClickEvent.event.id);
          //this.eventService.removeEventById(eventClickEvent.event.id);
          this.eventService.removeEventById(eventClickEvent.event.id).subscribe(events => console.log(events));


            /*
            events => { this.events = events.map((event) => {
            var date = new Date(event.start);
            var hour = date.getHours();

            console.log("EVENTS: " + this.events);

            if(hour === 7) {
              event['backgroundColor'] = 'red';
            }
            else if(hour === 15) {
              event['backgroundColor'] = 'green';
            }
            else if(hour === 23) {
              event['backgroundColor'] = 'black';
            }

            return event;
          })});
          */
        },

        eventDragStop: (eventDragStopEvent) => {
          console.log("EVENT DRAG STOP !!!");
        },

        eventReceive: (eventReceiveEvent) => {
          console.log(eventReceiveEvent);
          //eventReceiveEvent.event.setAllDay(false, {maintainDuration: true});



          //eventReceiveEvent['backgroundColor'] = 'red';
          this.eventService.addEvent(eventReceiveEvent);
        }
    };

  }

  ngAfterViewInit() {

    this.calendar = this.fullcalendar.getCalendar();
    console.log("CALENDAR: " + this.calendar);

  }

}

正如您在ngOnInit()方法中看到的那样，我正在订阅服务的getEvents()方法，该服务将呈现的事件列表返回为 Observable（我这样做是因为在返回的输出中我正在为不同的事件处理不同的颜色类型，但这与我的问题并不严格相关......它工作正常）。

所以，正如你所看到的，这个组件类包含这个钩子方法eventClick: (eventClickEvent)处理点击我的日历的事件。我正在考虑调用在我的服务中定义的删除事件方法并再次呈现它，但它不起作用（我已经做了几次尝试，但它不起作用）。我也不确定这是解决问题的正确方法。

根据我对ngOnInit()方法的理解，我订阅了我的日历事件数组，因此链接这个数组的内容，这个更改被发布并且它应该再次呈现，我也尝试了这个，但它不起作用......所以我认为我可能在 Angular 逻辑中遗漏了一些东西。

这是我的服务类的代码：

import { Injectable } from '@angular/core';
import { HttpClientModule, HttpClient } from '@angular/common/http'
import { BehaviorSubject, Observable } from 'rxjs';

@Injectable()
export class EventService {

  private events = [];

  /*
  private events = [
    {id: 1, title: 'All Day Event', start: '2017-02-01'},
    {id: 2, title: 'Long Event', start: '2017-02-07', end: '2017-02-10'},
    {id: 3, title: 'Repeating Event', start: '2017-02-09T16:00:00'},
    {id: 3, title: 'test', start: '2017-02-20T07:00:00'},
  ];
  */

  private people = [
    {id: 1, name: "PERSONA 1"},
    {id: 2, name: "PERSONA 2"},
    {id: 3, name: "PERSONA 3"},
    {id: 4, name: "PERSONA 4"},
    {id: 5, name: "PERSONA 5"},
  ]

  public eventData = new BehaviorSubject(this.events);

  constructor(private http: HttpClient) {}

  getEvents(): Observable<any[]> {
    return this.eventData.asObservable();
  }


  addEvent(event) {
    //console.log(event.event.start);
    //console.log(event);
    const newEvent = {id: 5, title: event.event.title, start: event.event.start, end: event.event.end};
    this.events.push(newEvent);
    this.eventData.next([...this.events]);
    //console.log(this.events);
  }

  removeEventById(id:number): Observable<any[]>  {
    console.log("EVENTDATA: " + this.eventData.getValue());

    return this.eventData.asObservable();
  }


  /*
  removeEventById = (id:number) => {
    this.events = [];
    //return this.events.filter(each=>each.id!=id);

  }
  */

  getPeople(): Promise<any[]> {
    return Promise.all(this.people)
        .then(res => {
          console.log(res);
          return res;
        })
  }

}

那么有什么问题呢？我错过了什么？什么是正确处理我的问题的聪明解决方案？
