Globalization in EJ2 TypeScript Datepicker control
3 Feb 202412 minutes to read
Globalization is the combination of adapting the component to various languages by means of parsing and formatting the date or number Internationalization
and also by adding cultural specific customizations and translating the text localization
By default, DatePicker date format, week and month names are specific to English culture. It utilizes the Essential JavaScript 2 Internationalization
package to parse and format the date object based on the culture by using the official UNICODE CLDR
JSON data and it allows to load the culture specific CLDR JSON data by using loadCldr
method
The DatePicker component supports only the Gregorian type of calendar. All the Essential JS 2 component are specific to English culture (‘en-US’). If you want 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 the
CLDR-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.ts
file. To import JSON data we need to install the JSON plugin loader. Here we have used the SystemJS JSON plugin loader.
npm install systemjs-plugin-json --save-dev
- Once installed, configure the
system.config.js
configuration settings as like below to map thesystemjs-plugin-json
loader.
System.config({
paths: {
'npm:': './node_modules/',
'syncfusion:': 'npm:@syncfusion/'
},
map: {
app: 'app',
//Syncfusion packages mapping
"@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
"@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
"@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
"@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
"@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
"@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
"@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
"@syncfusion/ej2-calendars": "syncfusion:ej2-calendars/dist/ej2-calendars.umd.min.js",
"cldr-data": 'npm:cldr-data',
"plugin-json": "npm:systemjs-plugin-json/json.js"
},
meta: {
'*.json': { loader: 'plugin-json' }
},
packages: {
'app': { main: 'app', defaultExtension: 'js' },
'cldr-data': { main: 'index.js', defaultExtension: 'js' }
}
});
System.import('app');
-
Now use the
loadCldr
method to load the culture specific CLDR JSON data from the installed location toapp.ts
file. -
DatePicker displayed
Sunday
as the first day of week based on default culture (“en-US”). If you want to display the DatePicker with loaded culture’s first day of week, you need to importweekdata.json
file from thecldr-data/suppemental
as given in the code example.
//Load the loadCldr from ej2-base
import { loadCldr } from '@syncfusion/ej2-base';
declare var require: any;
loadCldr(
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 DatePicker. The DatePicker 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. |
placeholder | Hint to describe expected value in input element. |
- Before changing the culture other than
English
, ensure that locale text for the concerned culture is loaded throughload
method of
L10n class.
//Load the L10n from ej2-base
import { L10n } from '@syncfusion/ej2-base';
//load the locale object to set the localized placeholder value
L10n.load({
'de': {
'datepicker': { placeholder: 'Wählen Sie ein Datum aus',
today:'heute' }
}
});
- Set the culture by using the
locale
property. The below code example, initialize the DatePicker component inGerman
culture with corresponding localized text.
//Load the L10n from ej2-base
import { L10n } from '@syncfusion/ej2-base';
import { DatePicker } from '@syncfusion/ej2-calendars';
//load the locale object to set the localized placeholder value
L10n.load({
'de': {
'datepicker': { placeholder: 'Wählen Sie ein Datum aus',
today:'heute' }
}
});
let datepickerObject: DatePicker = new DatePicker({
//sets the locale.
locale: 'de'
});
datepickerObject.appendTo('#element');
The following example demonstrates the DatePicker in German
culture.
import { DatePicker } from '@syncfusion/ej2-calendars';
//Load the L10n, loadCldr from ej2-base
import { loadCldr, L10n } from '@syncfusion/ej2-base';
//load the CLDR data files.
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);
L10n.load({
'de': {
'datepicker': {
placeholder: 'Wählen Sie ein Datum aus',
today:'heute'
}
}
});
// creates the simple DatePicker component
let datepickerObject: DatePicker = new DatePicker({
// sets the locale property.
locale: 'de',
value: new Date()
});
datepickerObject.appendTo('#element');

Right-To-Left
The DatePicker 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.
import { DatePicker } from '@syncfusion/ej2-calendars';
//Load the L10n from ej2-base
import { L10n, loadCldr } from '@syncfusion/ej2-base';
declare var require: any;
loadCldr(
require('cldr-data/supplemental/numberingSystems.json'),
require('cldr-data/main/he/ca-gregorian.json'),
require('cldr-data/main/he/numbers.json')
require('cldr-data/main/he/timeZoneNames.json')
);
//load the locale object to set the localized placeholder value
L10n.load({
'he': {
'datepicker': { placeholder: 'הזן תאריך',
today:'היום' }
}
});
// creates the datepicker with Hebrew culture.
let datepickerobject: DatePicker = new DatePicker({
//sets the locale
locale: 'he',
value: new Date(),
//sets the enableRtl
enableRtl: true
});
datepickerobject.appendTo('#element');
The below code example demonstrates the DatePicker component in Hebrew
culture and also explains how to set the localized text to
the placeholder using load
method of L10n class.
import { loadCldr, L10n } from '@syncfusion/ej2-base';
import { DatePicker } from '@syncfusion/ej2-calendars';
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);
L10n.load({
'he': {
'datepicker': {
placeholder: 'הזן תאריך',
today:'היום'
}
}
});
// creates the simple DatePicker component
let datepickerObject: DatePicker = new DatePicker({
//sets the locale
locale: 'he',
//sets the enableRtl
enableRtl: true,
//sets the value
value: new Date()
});
datepickerObject.appendTo('#element');
