Globalization

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 use the loadCldr method to load the culture specific CLDR JSON data.

In ASP.NET MVC refer the culture files directly from \node_modules\cldr-data location. But in ASP.NET Core, the static file contents are should present under wwwroot folder. For this, manually copy the CLDR-Data from the node_modules folder and place inside the wwwroot folder and refer from the \wwwroot\cldr-data location as like the below code examples

Example for ASP.NET Core

function loadCultureFiles(name) {
        var files = ['currencies.json', 'numbers.json' ];
        if (name === 'zh') {
            files.push('currencyData.json');
        }
        var loader = ej.base.loadCldr;
        var loadCulture = function () {
            var val, ajax;
            if (name === 'zh' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../cldr-data/main/'  + name + '/' + files[prop], 'GET', false);
            }
            ajax.onSuccess = function (value) {
                val = value;
            };
            ajax.send();
            loader(JSON.parse(val));

        };
        for (var prop = 0; prop < files.length; prop++) {
            loadCulture();
        }
    }
loadCultureFiles('de');

Example for ASP.NET MVC

function loadCultureFiles(name) {
        var files = ['currencies.json', 'numbers.json'];
        if (name === 'zh') {
            files.push('currencyData.json');
        }
        var loader = ej.base.loadCldr;
        var loadCulture = function () {
            var val, ajax;
            if (name === 'zh' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/main/'+ name + '/' + files[prop], 'GET', false);
            }
            ajax.onSuccess = function (value) {
                val = value;
            };
            ajax.send();
            loader (JSON.parse(val));
        };
        for (var prop = 0; prop < files.length; prop++) {
            loadCulture();
        }
    }
loadCultureFiles('de');

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
  • Before changing to a culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n class.
ej.base.L10n.load({
        'en': {
            'numerictextbox': { incrementTitle: 'Increment value', decrementTitle: 'Decrement value' }
        },
        'de': {
            'numerictextbox': { incrementTitle: 'Wert erhöhen', decrementTitle: 'Dekrementwert' }
        },
        'zh': {
            'numerictextbox': { incrementTitle: '增值', decrementTitle: '遞減值' }
        }
    });

The following example demonstrates the NumericTextBox in German culture.

NumericTextBox Sample

Right to Left

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.
