我正在使用PrimeNG Full Calendar组件制作一个Angular应用,这个组件。https:/primefaces.orgprimengshowcase#fullcalendar。
那是基于Angular FullCalendar组件,这个。https:/fullcalendar.io
在这里你可以找到我的全部代码。https:/bitbucket.orgdgs_poste_teamsoc_calendarsrcmaster。
所以我有一个这样的日历。
现阶段我想实现的是,当用户点击一个特定的事件时,所有进入这个日历的事件都将被删除(在第二阶段,我将实现只有被点击的特定事件才会被删除,但目前我尽量保持逻辑简单)。
所以这就是控制我的日历组件的类。

import { EventService } from '../event.service';
import dayGridPlugin from '@fullcalendar/daygrid';

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 = {

console.log(eventClickEvent.event.id);
//this.eventService.removeEventById(eventClickEvent.event.id);

*/
},
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);
}
}
你可以看到进入 ngOnInit() 方法,我订阅了 getEvents() 方法,以Observable的形式返回已渲染的事件列表(我这样做是因为在返回的输出中,我处理了不同事件类型的不同颜色,但这与我的问题没有严格的关系......它工作得很好)。
所以,如你所见,这个组件类包含了这个钩子方法 事件点击。(eventClickEvent) 处理点击我的日历上的一个事件。我想调用一个定义到我的服务中的删除事件方法,然后再重新渲染,但这是行不通的(我已经做了几次尝试,但还是行不通)。我也不确定这是解决问题的正确方法。
从我了解到的 ngOnInit() 方法,我有订阅我的日历事件数组,所以链这个数组的内容的变化发布,它应该再次呈现,我也试过,但它是不工作的......所以我认为,可能是我在Angular逻辑遗漏的东西。
这是我服务类的代码。
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;
})
}
}
那到底是哪里出了问题?我遗漏了什么?有什么聪明的办法可以正确处理我的问题?
所以有你几件事应该到位。
对于删除所有事件。
在events.service中
public deleteEvents() { this.events = []; this.eventData.next(this.events); }
在 fullCalendar.component.ts fullCalendar选项:-
eventClick: (eventClickEvent) => { console.log("EVENT CLICKED !!!"); this.eventService.deleteEvents(); }
首先,在你的日历中,每个事件都应该有一个唯一的ID。目前在你的addEvent方法中,你给每个事件提供了相同的ID,即5。
public currentId = 1;
public addEvent() {
const newEvent = {id: this.currentId++, title: event.event.title, start: event.event.start, end: event.event.end};
//Remaining Add Event Code.
}
这样一来,每当事件被添加到你的日历时,你就会有一个唯一的ID。
现在,当事件被点击时,你会调用一个方法,即 removeEventById()。应该写成:-
removeEventById(id): Observable<any[]> {
this.events = this.events.filter((event) => event.id!==+id);
this.eventData.next(this.events);
return this.eventData.asObservable();
}
注意:-你从事件点击对象中接收到的id是字符串,而你在数组中的id是数字。因此,我在接收到的id中加入了+,以便在数字中解析出与id相匹配的id,并删除必要的项目。
在 fullCalendar.component.ts fullCalendar选项:-
eventClick: (eventClickEvent) => {
console.log("EVENT CLICKED !!!");
this.eventService.removeEventById(eventClickEvent.event.id).subscribe(events => console.log(events));
}
primeng fullcalendar是由fullcalendar.io开发的,你可以过滤数据,然后分配给eventData。我把你的代码创建在 演示
this.eventService.removeEventById(eventClickEvent.event.id).subscribe(events => console.log(events));
在你的方法中
removeEventById(id:number): Observable<any[]> {
this.events=this.events.filter(each=>each.id!=id);
this.eventData.next([...this.events]);
return this.eventData.asObservable();
}
由于您使用的是 Observables
,您可以使用 map
经营者与 Array.prototype.filter
:
import { Injectable } from '@angular/core';
import { BehaviorSubject, Observable } from 'rxjs';
import { map } from 'rxjs/operators';
removeEventById(id:number): Observable<any[]> {
return this.getEvents()
.pipe(
map(items => items.filter(item => item.id == id))
);
}
所以你的服务可以是这样的。
@Injectable()
export class MyServices {
private events = [
{
id: 1,
title: 'Foo 1',
date: '2020-06-07'
},
{
id: 2,
title: 'Foo 2',
date: '2020-06-08'
},
{
id: 3,
title: 'Foo 3',
date: '2020-06-05'
}
];
public eventData = new BehaviorSubject(this.events);
constructor() { }
sayHello() {
console.log("Say Hello");
}
getEvents(): Observable<any[]> {
return this.eventData.asObservable();
}
addEvent(event) {
const newEvent = {id: 5, title: event.event.title,
start: event.event.start, end: event.event.end};
this.events.push(newEvent);
this.eventData.next(Object.assign({}, this.events));
}
removeEventById(id:number): Observable<any[]> {
return this.getEvents()
.pipe(
map(items => items.filter(item => item.id == id))
);
}
}
and your.component.ts
可能是这样的。
export class AppComponent implements OnInit {
options: any;
eventsModel: any;
@ViewChild('fullcalendar') fullcalendar: FullCalendarComponent;
@ViewChild('external') external: ElementRef;
constructor(private myServices: MyServices){
this.myServices.sayHello();
}
eventClick(model) {
this.myServices.removeEventById(model.id)
.subscribe(s => this.eventsModel = s);
}
