Globalization in JavaScript NumericTextBox control

28 Mar 2023 / 4 minutes to read

Localization

Localization library allows users to localize the default text contents of the NumericTextBox to different cultures using the locale property. In NumericTextBox, spin buttons title for the tooltip will be localized based on the culture.

Locale key	en-US (default)
incrementTitle	Increment value
decrementTitle	Decrement value

Loading translations

To load translation object in your application use load function of L10n class.

The below example demonstrates the NumericTextBox in German culture with the spin buttons tooltip.

import { NumericTextBox } from '@syncfusion/ej2-inputs';
import { L10n } from '@syncfusion/ej2-base';

// Load `German` culture to override spin buttons tooltip text
L10n.load({
    'de': {
        'numerictextbox': {
            incrementTitle: 'Wert erhöhen', decrementTitle: 'Dekrementwert'
        }
    },

});

let numeric: NumericTextBox = new NumericTextBox({
    // sets `German` culture using the culture value 'de'
    locale: 'de',
    // sets value to the NumericTextBox
    value: 10
});

// renders initialized NumericTextBox
numeric.appendTo('#numeric');

Internationalization

Internationalization library provides support for formatting and parsing the number by using the official Unicode CLDR JSON data and also provides the loadCldr method to load the culture specific CLDR JSON data. The NumericTextBox comes with built-in internationalization support to adapt based on culture. For more information about internationalization, refer to this link.

By default, 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). For more information about CLDR-Data, refer to this 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 the systemjs-plugin-json loader.

System.config({
paths: {
    'syncfusion:': 'npm:@syncfusion/'
},
map: {
    app: 'app',

    //Syncfusion packages mapping
    "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
    "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.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 import the required culture from the installed location to app.ts file as like the below code snippets.

declare var require: any;

loadCldr(
    require('cldr-data/main/de/numbers.json'),
    require('cldr-data/main/de/currencies.json'),
    require('cldr-data/supplemental/numberingSystems.json'),
    require('cldr-data/supplemental/currencyData.json')
);

Set the culture by using the locale property.

The below example demonstrates the NumericTextBox in German culture with the EUR currency format.

import * as currencyData from './currencyData.json';
import * as numbers from './numbers.json';
import * as currencies from './currencies.json';

loadCldr(numberingSystems, currencyData, numbers, currencies);

L10n.load({
'de': {
  'numerictextbox': { incrementTitle: 'Wert erhöhen', decrementTitle: 'Dekrementwert'}
}
});

let currency: NumericTextBox = new NumericTextBox({
// sets `German` culture using the culture value 'de'
locale: 'de',
// sets the 'EUR' currency format
currency: 'EUR',
format: 'c2',
value: 100,
 });

currency.appendTo('#numeric');

Right to Left(RTL)

RTL provides an option to switch the text direction and layout of the NumericTextBox component from right to left. It improves the user experiences and accessibility for users who use right-to-left languages (Arabic, Farsi, Urdu, etc.). To enable RTL NumericTextBox, set the enableRtl to true.
