Globalization in Vue DateRangePicker component

02 Aug 2021 / 5 minutes to read

Globalization is the combination of internationalization 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, DateRangePicker date format, week, and month names are specific to the 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. It allows to load culture specific CLDR JSON data by using loadCldr method.

To use a different culture other than English, follow the below steps:

Install the CLDR-Data package by using the below command (Installs the CLDR JSON data). To know more about CLDR-Data refer to the CLDR-Data link.

npm install cldr-data --save

Once the package is installed, you can find the culture specific JSON data under the location \node_modules\cldr-data.

Import the installed CLDR JSON data into the app.vue file.
Use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.vue file.
DateRangePicker displayed Sunday as the first day of week based on default culture (“en-US”). If you want to display the DateRangePicker with loaded culture’s first day of week, you need to import weekdata.json file from the cldr-data/suppemental as given in the code example.

//Load the loadCldr from ej2-base
import { loadCldr } from '@syncfusion/ej2-base';

import * as numberingSystems from 'cldr-data/supplemental/numberingSystems.json';
import * as gregorian from 'cldr-data/main/de/ca-gregorian.json';
import * as numbers from 'cldr-data/main/de/numbers.json';
import * as timeZoneNames from 'cldr-data/main/de/timeZoneNames.json';
import * as weekData from 'cldr-data/supplemental/weekdata.json';// To load the culture based first day of week

loadCldr(numberingSystems, gregorian, numbers, timeZoneNames, weekData);

The Localization library allows you to localize default text content of the DateRangePicker. The DateRangePicker component has static text for today feature that can be changed to other cultures (Arabic, Deutsch, French, etc.) by defining the locale value and translation object.

Locale keywords	Text
placeholder	Hint to describe expected value in input element.
startLabel	Label to represent the start date.
endLabel	Label to represent the end date.
applyText	Text present in the apply button.
cancelText	Text present in the cancel button.
selectedDays	Text to represent selected days.
days	Text represents days.
customRange	Text present in the custom range button in presets container.

Before changing to a culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n 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': {
    'daterangepicker': { placeholder: 'Wählen Sie ein Datum aus' }
}
});

Set the culture by using the locale property.

The following example demonstrates the DateRangePicker in German culture.

Right-To-Left

The DateRangePicker supports RTL (right-to-left) functionality for languages like Arabic and Hebrew to displays the text in the right-to-left direction. Use enableRtl property to set the RTL direction. The following code example initialize the DateRangePicker component in Hebrew culture and also explains how to set the localized text to the placeholder using load method of L10n class.

Customize the date format

Representation of start and end date strings can be customized to required format by using format property. By default, the format is based on the culture. To know more about the date format standards, refer to the Internationalization Date Format section. In the following sample, the date strings are formatted to yyyy-MM-dd and in between the string “to” is set as a separator.
