Globalization in React TimePicker component

03 Mar 2021 / 4 minutes to read

Globalization is the combination of internationalization and localization. You can adapt the component to various languages by means of parsing and formatting the date or number internationalization , and also add culture specific customization and translation to the text localization.

By default, TimePicker time 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 culture specific CLDR JSON data. To go with the different culture other than English, follow the steps below.

Install the CLDR-Data package by using the following command (it installs all the CLDR JSON data). To known more about CLDR-Data refer 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.ts file.
Use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.ts file.
TimePicker displayed Sunday as the first day of week based on default culture (“en-US”). If you want to display the TimePicker 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 { 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 numberingSystems from 'cldr-data/supplemental/numberingSystems.json';

loadCldr(numberingSystems, gregorian, numbers);

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"
]
  }

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': {
    'timepicker': { placeholder: 'Wählen Sie Zeit'}
}
});

Set the culture by using the locale property. In the following code example, the DateTimePicker is initialized in German culture with corresponding localized text.

The following example demonstrates the TimePicker in German culture.

Right-To-Left

The TimePicker 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 code example demonstrates the TimePicker component in Arabic culture, also explains how to set the localized text to the placeholder using L10n.load method.
