Globalization in Angular Calendar component
27 Apr 20248 minutes to read
Globalization is the combination of internalization and localization. You can adapt the component to various languages by parsing and formatting the date or number Internationalization
and also add culture specific customization and translation to the text localization
.
By default, Calendar date format, week and month names are specific to American English culture. It utilizes the Essential JavaScript 2 Internationalization
package to parse and format the date object based on the culture by uses the official UNICODE CLDR
JSON data and also it provides the loadCldr
method to load the culture specific CLDR JSON data.
To go with the different culture other than English
, follow the below steps.
-
Install the
CLDR-Data
package by using the below command (it installs the CLDR JSON data). To know more about CLDR-Data refer theCLDR-Data
link.npm install cldr-data --save
Once the package installed, you can find the culture specific JSON data under the location /node_modules/cldr-data
.
-
Now import the installed CLDR JSON data into the
app.component.ts
file. -
Now use the
loadCldr
method to load the culture specific CLDR JSON data from the installed location toapp.component.ts
file. -
Calendar displayed
Sunday
as the first day of week based on default culture (“en-US”). If you want to display the Calendar with loaded culture’s first day of week, you need to importweekdata.json
file from thecldr-data/suppemental
as given in the code example.//import the loadCldr from ej2-base import { loadCldr} from '@syncfusion/ej2-base'; declare var require: any; loadCldr( require('cldr-data/supplemental/numberingSystems.json'), require('cldr-data/main/de/ca-gregorian.json'), require('cldr-data/main/de/numbers.json'), require('cldr-data/main/de/timeZoneNames.json'), require('cldr-data/supplemental/weekdata.json')); // To load the culture based first day of week
The
Localization
library allows you to localize default text content of the Calendar. The Calendar component has static text for today feature that can be changed to other cultures (Arabic, Deutsch, French, etc.) by defining thelocale
value and translation object.
Locale keywords | Text |
---|---|
today | Name of the button to choose Today date. |
-
Before changing to a culture other than
English
, ensure that locale text for the concerned culture is loaded throughload
method ofL10n
class.//Load the L10n, loadCldr from ej2-base import { loadCldr, L10n } from "@syncfusion/ej2-base"; //load the locale object to set the localized placeholder value L10n.load({ de: { calendar: { today:"heute" } } });
-
Set the culture by using the
locale
property. The below code example, initialize the Calendar component inGerman
culture.import { Component } from '@angular/core'; //import the loadCldr from ej2-base import { loadCldr, L10n } from '@syncfusion/ej2-base'; declare var require: any; loadCldr( require('cldr-data/supplemental/numberingSystems.json'), require('cldr-data/main/de/ca-gregorian.json'), require('cldr-data/main/de/numbers.json'), require('cldr-data/main/de/timeZoneNames.json') ); @Component({ selector: 'app-root', template: ` <!-- Sets the value, locale --> <ejs-calendar [value]='dateValue' locale='de'></ejs-calendar>` }) export class AppComponent { public dateValue: Object = new Date(); ngOnInit(): void { /*loads the localization text*/ L10n.load({ 'de': { 'calendar': { today:"heute" } } }); } constructor() { } }
The following example demonstrates the Calendar in German
culture.
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { CalendarModule } from '@syncfusion/ej2-angular-calendars'
import { Component } from '@angular/core';
import { loadCldr, L10n } from '@syncfusion/ej2-base';
// Here we have referred local json files for preview purpose
import * as numberingSystems from './numberingSystems.json';
import * as gregorian from './ca-gregorian.json';
import * as numbers from './numbers.json';
import * as timeZoneNames from './timeZoneNames.json';
loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);
@Component({
imports: [
CalendarModule //declaration of ej2-angular-calendars module into NgModule
],
standalone: true,
selector: 'app-root',
template: `
<!-- Sets the value, locale -->
<ejs-calendar [value]='dateValue' locale='de'></ejs-calendar>`
})
export class AppComponent {
public dateValue: Object = new Date();
ngOnInit(): void {
/*loads the localization text*/
L10n.load({
'de': {
'calendar': {
today:"heute"
}
}
});
}
constructor() {
}
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
Right-To-Left
The Calendar supports right-to-left functionality for languages like Arabic, Hebrew to displays the text in the right-to-left direction. Use enableRtl
property to set the RTL direction.
The following example demonstrates the Calendar in Arabic
culture with enableRtl
property.
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { CalendarModule } from '@syncfusion/ej2-angular-calendars'
import { Component } from '@angular/core';
import { loadCldr, L10n} from '@syncfusion/ej2-base';
// Here we have referred local json files for preview purpose
import * as numberingSystems from './numberingSystems.json';
import * as gregorian from './ca-gregorian.json';
import * as numbers from './numbers.json';
import * as timeZoneNames from './timeZoneNames.json';
loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);
@Component({
imports: [
CalendarModule //declaration of ej2-angular-calendars module into NgModule
],
standalone: true,
selector: 'app-root',
template: `
<!-- Sets the value, locale,enableRtl -->
<ejs-calendar [value]='dateValue' locale='ar' enableRtl='true'></ejs-calendar>
`
})
export class AppComponent {
public dateValue: Object = new Date();
ngOnInit(): void {
L10n.load({
'ar': {
'calendar': { today: "اليوم"}
}
});
}
constructor() {
}
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
