Globalization

Globalization is the combination of adapting the component to various languages by means of parsing and formatting the date or number Internationalization, and also by adding cultural specific customizations and translating the text localization.

By default, DateRangePicker date format, week, and month 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.

Set the culture by using the locale property.

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). To know more 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 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 = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            ajax = new ej.base.Ajax(location.origin + location.pathname + '/../wwwroot/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(prop);
        }
    }

Example for ASP.NET MVC

    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            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(prop);
        }
    }

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.

    var L10n = ej.base.L10n;
    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'
        }
    }
});

The following example demonstrates the DateRangePicker in German culture.

tagHelper

<ejs-daterangepicker id="daterangepicker"></ejs-daterangepicker>
		
<script>
    document.addEventListener('DOMContentLoaded', function () {
        daterangepicker = document.getElementById('daterangepicker').ej2_instances[0];
        var L10n = ej.base.L10n;
        L10n.load({
            'de': {
                'daterangepicker': { placeholder:'Einen Bereich auswählen',
                 today: 'heute' }
            }
        });
        loadCultureFiles('de');
        daterangepicker.locale = 'de';
   });

    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        if (name === 'ar') {
            files.push('numberingSystems.json');
        }
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
             if (name === 'ar' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../wwwroot/scripts/cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../wwwroot/scripts/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(prop);
        }
    }

</script>

Right-To-Left

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

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

The following example demonstrates DateRangePicker in Arabic culture with right-to-left direction.

tagHelper

<ejs-daterangepicker id="daterangepicker" enableRtl=true></ejs-daterangepicker>

<script>
    document.addEventListener('DOMContentLoaded', function () {
        daterangepicker = document.getElementById('daterangepicker').ej2_instances[0];
        var L10n = ej.base.L10n;
        L10n.load({
            'ar': {
              'daterangepicker': { placeholder: 'حدد نطاقا',
                                today: 'اليوم' }
            }
        });
        loadCultureFiles("ar");
        daterangepicker.locale = 'ar';
    });

    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        if (name === 'ar') {
            files.push('numberingSystems.json');
        }
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
             if (name === 'ar' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../wwwroot/scripts/cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../wwwroot/scripts/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(prop);
        }
    }

</script>
