问题描述
运行全日历控制角度项目,该项目在作者网站上可用。
添加自定义按钮后,我需要通过点击事件从完整的日历控件(getEventSources)中检索事件:
customButtons: {
myCustomButton: {
text: 'Update',click: function() {
debugger;
alert('clicked the custom button!');
}
}
},
如何在click方法中获取日历对象。我正在使用Angular项目:FullCalendar Angular
AppComponent代码:
import { Component,ViewChild } from '@angular/core';
import { FullCalendarComponent,CalendarOptions,DateSelectArg,EventClickArg,EventApi,Calendarapi,Calendar,DateEnv,getDateMeta,CalendarContent,CalendarDataManager,CalendarRoot,triggerDateSelect,} from '@fullcalendar/angular';
import { INITIAL_EVENTS,createEventId,getRecentMonthEvents } from './event-utils';
import { AppService } from './app.service';
import { ActivatedRoute } from '@angular/router';
import { DatePipe } from '@angular/common';
import { THIS_EXPR } from '@angular/compiler/src/output/output_ast';
import { global } from '@angular/compiler/src/util';
import { environment } from 'src/environments/environment';
@Component({
selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.scss']
})
export class AppComponent {
@ViewChild('calendar') calendarComponent: FullCalendarComponent;
constructor()
{
this.calendarMonth = (new Date().getMonth() + 1);
this.calendarYear = new Date().getFullYear();
}
calendarVisible = true;
public calendarMonth: number;
public calendarYear: number;
calendarOptions: CalendarOptions = {
headerToolbar: {
left: 'prev,next today myCustomButton',center: 'title',right: 'dayGridMonth'//,timeGridWeek,timeGridDay,listWeek'
},initialView: 'dayGridMonth',weekends: true,editable: true,selectable: true,selectMirror: true,dayMaxEvents: true,eventContent: function(arg) {
var ProdCnt = arg.event.extendedProps.budgetDailyNumber;
let toggleSwitch = document.createElement('LABEL');
toggleSwitch.className = "switch";
if (arg.event.extendedProps.isWorkDay) {
toggleSwitch.innerHTML = '<input type="checkBox"><span class="slider round"></span><br>';
} else {
toggleSwitch.innerHTML = '<input type="checkBox" checked><span class="slider round"></span><br>';
}
let textBox = document.createElement('input');
textBox.setAttribute("type","text");
textBox.setAttribute("value",ProdCnt);
textBox.setAttribute("style","width: 20px;height: 20px;background-color: white;");
let arrayOfDomNodes = [ toggleSwitch,textBox ]
return { domNodes: arrayOfDomNodes }
},customButtons: {
myCustomButton: {
text: 'Update',click: function() {
alert('clicked the custom button!');
}
}
},select: this.handleDateSelect.bind(this),eventClick: this.handleEventClick.bind(this),eventsSet: this.handleEvents.bind(this),initialDate: new Date(),// vieWrender: function(view,element) {
// var b = $('#calendar').fullCalendar('getDate');
// alert(b.format('L'));
// },events: {
//getCalendarMonth
url: 'http://localhost:50324/api/productionforecast?month=' + environment.calMonth +'&year=' + environment.calYear,//url: 'http://localhost:50324/api/productionforecast?month=' +(new Date().getMonth() + 1)+'&year=' + (new Date().getFullYear()),method: 'GET',failure: function() {
alert('there was an error while fetching events!');
},color: 'yellow',// a non-ajax option
textColor: 'black' // a non-ajax option
}
/* you can update a remote database when these fire:
eventAdd:
eventChange:
eventRemove:
*/
};
currentEvents: EventApi[] = [];
handleCalendarToggle() {
this.calendarVisible = !this.calendarVisible;
}
handleWeekendsToggle() {
const { calendarOptions } = this;
calendarOptions.weekends = !calendarOptions.weekends;
}
handleDateSelect(selectInfo: DateSelectArg) {
const title = prompt('Please enter a new title for your event');
const calendarapi = selectInfo.view.calendar;
calendarapi.unselect(); // clear date selection
if (title) {
calendarapi.addEvent({
id: createEventId(),title,start: selectInfo.startStr,end: selectInfo.endStr,allDay: selectInfo.allDay
});
}
}
handleEventClick(clickInfo: EventClickArg) {
if (confirm(`Are you sure you want to delete the event '${clickInfo.event.title}'`)) {
clickInfo.event.remove();
}
}
handleEvents(events: EventApi[]) {
this.currentEvents = events;
}
getCalendarMonth()
{
debugger;
return this.calendarComponent.getApi().getDate().getMonth();
}
public loadProductionforecast(month,year)
{
// this.appService.getProductionforecast(month,year).subscribe((data: any) => {
// debugger;
}
}
问题:
-
在名为 myCustomButton 的自定义按钮的Click事件中,我们无法访问 calendarComponent 对象。
解决方法
在自定义按钮的click事件中,我们可以访问调用应用程序组件方法,如下所示:
customButtons: {
myCustomButton: {
text: 'Update',click: () => this.customFunction()
}
}
