Install: npm install ionic2-calendar --save
Import the ionic2-calendar module:
import { NgModule } from '@angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { MyApp } from './app/app.component';
import { NgCalendarModule } from 'ionic2-calendar';
@NgModule({
declarations: [
MyApp
],
imports: [
NgCalendarModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp
]
})
export class AppModule {}
If you are using PageModule, you need to import the NgCalendarModule in your page module
import { NgCalendarModule } from 'ionic2-calendar';
@NgModule({
declarations: [
MyPage
],
imports: [
IonicPageModule.forChild(MyPage),
NgCalendarModule
],
entryComponents: [
MyPage
]
})
export class MyPageModule {}
Add the directive in the html page
<calendar [eventSource]="eventSource"
[calendarMode]="calendar.mode"
[currentDate]="calendar.currentDate"
(onCurrentDateChanged)="onCurrentDateChanged($event)"
(onRangeChanged)="reloadSource(startTime, endTime)"
(onEventSelected)="onEventSelected($event)"
(onTitleChanged)="onViewTitleChanged($event)"
(onTimeSelected)="onTimeSelected($event)"
step="30">
</calendar>
ionic serve uses tsc to compile the code, while ionic build/run uses ngc to compile the code.
It requires explicit dependency on the compiled ngfactory files for each component.
I couldn’t find a way to configure the build command includes the ngfactory of the child components automatically.
So the workaround is to import them explicitly.
Add below lines in main.prod.ts
import { CalendarComponent } from 'ionic2-calendar/calendar';
import { MonthViewComponent } from 'ionic2-calendar/monthview';
import { WeekViewComponent } from 'ionic2-calendar/weekview';
import { DayViewComponent } from 'ionic2-calendar/dayview';
<calendar ... [locale]="calendar.locale"></calendar>
calendar = {
locale: 'en-GB'
};
<calendar ... [markDisabled]="markDisabled"></calendar>
markDisabled = (date: Date) => {
var current = new Date();
return date < current;
};
<calendar ... [dateFormatter]="calendar.dateFormatter"></calendar>
calendar = {
dateFormatter: {
formatMonthViewDay: function(date:Date) {
return date.getDate().toString();
},
formatMonthViewDayHeader: function(date:Date) {
return 'testMDH';
},
formatMonthViewTitle: function(date:Date) {
return 'testMT';
},
formatWeekViewDayHeader: function(date:Date) {
return 'testWDH';
},
formatWeekViewTitle: function(date:Date) {
return 'testWT';
},
formatWeekViewHourColumn: function(date:Date) {
return 'testWH';
},
formatDayViewHourColumn: function(date:Date) {
return 'testDH';
},
formatDayViewTitle: function(date:Date) {
return 'testDT';
}
}
};
dir
If set to "rtl", the calendar supports RTL language. This feature is only supported in Ionic 2.3.0 version onwards.
Default value: ""
scrollToHour
Make weekview and dayview scroll to the specific hour after entering to the new view.
Default value: 0
preserveScrollPosition
If set to true, the previous/next views in weekview and dayview will also scroll to the same position as the current active view.
Default value: false
lockSwipeToPrev
If set to true, swiping to previous view is disabled.
Default value: false
<calendar ... [lockSwipeToPrev]="lockSwipeToPrev"></calendar>
onCurrentDateChanged(event:Date) {
var today = new Date();
today.setHours(0, 0, 0, 0);
event.setHours(0, 0, 0, 0);
if (this.calendar.mode === 'month') {
if (event.getFullYear() < today.getFullYear() || (event.getFullYear() === today.getFullYear() && event.getMonth() <= today.getMonth())) {
this.lockSwipeToPrev = true;
} else {
this.lockSwipeToPrev = false;
}
}
}
lockSwipes
If set to true, swiping is disabled.
Default value: false
Note: Since swiping is disabled, you could set currentDate to move the calendar to previous/next view. Do not set lockSwipeToPrev in the constructor phase. It will cause the view not updating when changing the currentDate. You could either set it in some callback function after initialization phase or use setTimeout to trigger some delay.
<calendar ... [lockSwipeToPrev]="lockSwipeToPrev"></calendar>
ngAfterViewInit() {
var me = this;
setTimeout(function() {
me.lockSwipes = true;
},100);
}
<calendar ... startHour="9"></calendar>
<calendar ... endHour="19"></calendar>
<calendar ... spaceBetween="10"></calendar>
<calendar ... (onCurrentDateChanged)="onCurrentDateChanged($event)"></calendar>
onCurrentChanged = (ev: Date) => {
console.log('Currently viewed date: ' + ev);
};
<calendar ... (onRangeChanged)="onRangeChanged($event)"></calendar>
onRangeChanged = (ev: { startTime: Date, endTime: Date }) => {
Events.query(ev, (events) => {
this.eventSource = events;
});
};
<calendar ... (onEventSelected)="onEventSelected($event)"></calendar>
onEventSelected = (event) => {
console.log(event.title);
};
<calendar ... (onTimeSelected)="onTimeSelected($event)"></calendar>
onTimeSelected = (ev: { selectedTime: Date, events: any[] }) => {
console.log('Selected time: ' + ev.selectedTime + ', hasEvents: ' + (ev.events !== undefined && ev.events.length !== 0));
};
<calendar ... (onTitleChanged)="onViewTitleChanged($event)"></calendar>
onViewTitleChanged = (title: string) => {
this.viewTitle = title;
};
Note: For any css class appear in the customized template, you need to specify the styles by yourself. The styles defined in the calendar component won’t be applied because of the view encapsulation.
<template #template let-view="view" let-row="row" let-col="col">
{{view.dates[row*7+col].label}}
</template>
<calendar ... [monthviewDisplayEventTemplate]="template"></calendar>
<template #template let-view="view" let-row="row" let-col="col">
{{view.dates[row*7+col].label}}
</template>
<calendar ... [monthviewInactiveDisplayEventTemplate]="template"></calendar>
<template #template let-showEventDetail="showEventDetail" let-selectedDate="selectedDate" let-noEventsLabel="noEventsLabel">
...
</template>
<calendar ... [monthviewEventDetailTemplate]="template"></calendar>
<template #template let-displayEvent="displayEvent">
<div class="calendar-event-inner">{{displayEvent.event.title}}</div>
</template>
<calendar ... [weekviewAllDayEventTemplate]="template"></calendar>
<template #template let-displayEvent="displayEvent">
<div class="calendar-event-inner">{{displayEvent.event.title}}</div>
</template>
<calendar ... [weekviewNormalEventTemplate]="template"></calendar>
<template #template let-displayEvent="displayEvent">
<div class="calendar-event-inner">{{displayEvent.event.title}}</div>
</template>
<calendar ... [dayviewAllDayEventTemplate]="template"></calendar>
<template #template let-displayEvent="displayEvent">
<div class="calendar-event-inner">{{displayEvent.event.title}}</div>
</template>
<calendar ... [dayviewNormalEventTemplate]="template"></calendar>
EventSource is an array of event object which contains at least below fields:
var startTime = new Date(Date.UTC(2014, 4, 8));
var endTime = new Date(Date.UTC(2014, 4, 9));
Note The calendar only watches for the eventSource reference for performance consideration. That means only you manually reassign the eventSource value, the calendar gets notified, and this is usually fit to the scenario when the range is changed, you load a new data set from the backend. In case you want to manually insert/remove/update the element in the eventSource array, you can call instance method ‘loadEvents’ event to notify the calendar manually.
import { CalendarComponent } from "ionic2-calendar/calendar";
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
@ViewChild(CalendarComponent) myCalendar:CalendarComponent;
eventSource;
…
loadEvents: function() {
this.eventSource.push({
title: 'test',
startTime: startTime,
endTime: endTime,
allDay: false
});
this.myCalendar.loadEvents();
}
}
You could use locale option to achieve the localization.
If locale option is not specified, the calendar will use the LOCALE_ID set at the module level.
By default, the LOCALE_ID is en-US. You can override it in the module as below. If you pass undefined, the LOCALE_ID will be detected using the browser language setting. But using explicit value is recommended, as browser has different level of localization support.
Note that the event detail section in the month view doesn't support locale option, only LOCALE_ID takes effect. This is because it uses DatePipe in html directly. You could easily leverage customized event detail template to switch to other locale.
import { NgModule, LOCALE_ID } from '@angular/core';
@NgModule({
…
providers: [
{ provide: LOCALE_ID, useValue: 'zh-CN' }
]
})
For version 0.4.x which depends on Ionic 3.9.2 and Angular 5.0, locale module needs to be registered explicitly in module file as below.
import { registerLocaleData } from '@angular/common';
import localeZh from '@angular/common/locales/zh';
registerLocaleData(localeZh);
If you want to change the locale dynamically, you should use locale option instead of LOCALE_ID.
In the CPU profile, the default Intl based localization code occupies a big portion of the execution time. If you don’t need localization on certain parts, you can use the custom dateFormatter to override the date transform method. For example, the date in month view usually doesn’t require localization, you could use below code to just display the date part. If the month view day header doesn’t need to include the date, you could also use a string array containing static labels to save the date calculation.
<calendar ... [dateFormatter]="calendar.dateFormatter"></calendar>
calendar = {
dateFormatter: {
formatMonthViewDay: function(date:Date) {
return date.getDate().toString();
}
}
};
This component updates the ion-slide dynamically so that only 3 looped slides are needed.
The ion-slide in Ionic2 uses Swiper. It seems in the Swiper implementation, the next slide after the end of looped slide is a separate cached slide, instead of the first slide.
I can't find out a way to force refresh that cached slide, so you will notice that when sliding from the third month to the forth month, the preview month is not the forth month, but the first month.
Once the sliding is over, the slide will be forced to render the forth month.
Error: Cannot find module "intl"
Answer: This calendar has dependency on 'Intl'. Run npm install intl@1.2.5 to install the dependency
Error: Cannot read property 'getFullYear' of undefined
Answer: If you bind currentDate like this: [currentDate]="calendar.currentDate". You need to assign calendar.currentDate a valid Date object
How to switch the calendar to previous/next month programmatically?
Answer: You can change currentDate to the date in previous/next month.
