Globalization

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, DateRangePicker date format and meridian names are specific to the American 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 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 all the CLDR JSON data). To known 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 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.

  • Now use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.ts 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.

import { loadCldr } from "@syncfusion/ej2-base";

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 numberingSystems from 'cldr-data/supplemental/numberingSystems.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);

if you are facing the error /node_modules/cldr-data/main/de/*.json (1,1): unused expression, expected an assignment or function call when you are adding the json files to render the culture sample, then add the below configuration in your tslint.json file

"linterOptions": {
    "exclude": [
      "*.json",
      "**/*.json"
    ]
  }

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 from ej2-base
import { L10n } from "@syncfusion/ej2-base";

//load the locale object to set the localized placeholder value
L10n.load({
    'de': {
        'daterangepicker': {
          placeholder: 'Wählen Sie einen Bereich aus',
          startLabel: 'Wählen Sie Startdatum',
          endLabel: 'Wählen Sie Enddatum',
          applyText: 'Sich bewerben',
          cancelText: 'Stornieren',
          selectedDays: 'Ausgewählte Tage',
          days: 'Tage',
          customRange: 'benutzerdefinierten Bereich'
        }
    }
});
  • Set the culture by using the locale property.

The following example demonstrates the DateRangePicker in German culture.

Right-To-Left

The DateRangePicker supports right-to-left functionality for languages like Arabic, Hebrew, etc. To display the text in the right-to-left direction, use enableRtl property.

The following code example demonstrates the DateRangePicker component in Hebrew culture and also explains how to set the localized text to the placeholder using load method of L10n class.

Date Format

Date format is a way of representing the start date, end date strings in different string format in the textbox.

By default, the DateRangePicker’s start and end date string format is based on the culture. You can also set the own custom format by using the format property.

Once the date format property has been defined it will be common to all the cultures.

To know more about the date format standards, refer to the Internationalization Date Format section.

The following example demonstrates the DateRangePicker with the custom format (yyyy-MM-dd). Also, here the separator of the date values is changed to string “to”.
