Localization in EJ2 TypeScript Schedule control

5 Sep 202424 minutes to read

The Scheduler integrates different date-time formats and cultures, which allows it to function globally, thus meeting the diverse needs of different regions.

You can adapt the Scheduler to various languages by parsing and formatting the date or number (Internationalization), adding culture specific customization and translation to the text (Localization).

Globalization

The Internationalization library provides support for formatting and parsing the number, date, and time by using the official Unicode CLDR JSON data and also provides the loadCldr method to load the culture specific CLDR JSON data.

By default, Scheduler is set to follow the English culture (‘en-US’). If you want to go with different culture other than English, follow the below steps.

  • Install the ej2-cldr-data package using the Syncfusion npm package by running the command below..

    npm install @syncfusion/ej2-cldr-data

Once the package is installed, you can find the culture specific JSON data under the location \node_modules\@syncfusion\ej2-cldr-data.

  • Now import the required cultures from the installed location to app.ts file as given in the following code example.

    1. numberingSystems.json
    2. ca-gregorian.json
    3. numbers.json
    4. timeZoneNames.json
//import the loadCldr from ej2-base
import { loadCldr} from '@syncfusion/ej2-base';
import frNumberData from '@syncfusion/ej2-cldr-data/main/fr-CH/numbers.json';
import frtimeZoneData from '@syncfusion/ej2-cldr-data/main/fr-CH/timeZoneNames.json';
import frGregorian from '@syncfusion/ej2-cldr-data/main/fr-CH/ca-gregorian.json';
import frNumberingSystem from '@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json';

loadCldr(frNumberData, frtimeZoneData, frGregorian, frNumberingSystem);
  • Set the culture to Scheduler by using the locale property.
import { Schedule, Day, Week, WorkWeek, Month} from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';
import { loadCldr} from '@syncfusion/ej2-base';
import frNumberData from '@syncfusion/ej2-cldr-data/main/fr-CH/numbers.json';
import frtimeZoneData from '@syncfusion/ej2-cldr-data/main/fr-CH/timeZoneNames.json';
import frGregorian from '@syncfusion/ej2-cldr-data/main/fr-CH/ca-gregorian.json';
import frNumberingSystem from '@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json';

Schedule.Inject(Day, Week, WorkWeek, Month);
loadCldr(frNumberData, frtimeZoneData, frGregorian, frNumberingSystem);

let scheduleObj: Schedule = new Schedule({
    height: '550px',
    locale: 'fr-CH',
    selectedDate: new Date(2018, 1, 15),
    views: ['Day', 'Week', 'WorkWeek', 'Month'],
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Localizing the static Scheduler text

Localization library allows to display all the static text, date content, and time mode of the Scheduler following the localized language. To achieve this, set the locale property of Scheduler, as well as define the translation text of static words of Scheduler through the load method.

For example, the following code example lets you to define the French translation words for all the static words used in Scheduler.

import { Schedule, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-schedule';
import { L10n, loadCldr } from '@syncfusion/ej2-base';
import { scheduleData } from './datasource.ts';
import { loadCldr} from '@syncfusion/ej2-base';
import frNumberData from '@syncfusion/ej2-cldr-data/main/fr-CH/numbers.json';
import frtimeZoneData from '@syncfusion/ej2-cldr-data/main/fr-CH/timeZoneNames.json';
import frGregorian from '@syncfusion/ej2-cldr-data/main/fr-CH/ca-gregorian.json';
import frNumberingSystem from '@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json';
import * as localeTexts from './locale.json';

Schedule.Inject(Day, Week, WorkWeek, Month);
loadCldr(frNumberData, frtimeZoneData, frGregorian, frNumberingSystem);
L10n.load(localeTexts);

let scheduleObj: Schedule = new Schedule({
  height: '550px',
  locale: 'fr-CH',
  selectedDate: new Date(2018, 1, 15),
  views: ['Day', 'Week', 'WorkWeek', 'Month'],
  eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

            "summaryMonth": "month(s)",
            "summaryYear": "year(s)"
        }
    }
});

Setting date format

Scheduler can be used with all valid date formats and by default it follows the universal date format “MM/dd/yyyy”. If the dateFormat property is not specified particularly, then it will work based on the locale that is assigned to the Scheduler. As the default locale applied on Scheduler is “en-US”, this makes it to follow the “MM/dd/yyyy” pattern.

import { Schedule, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';

Schedule.Inject(Day, Week, WorkWeek, Month);
let scheduleObj: Schedule = new Schedule({
    height: '550px',
    dateFormat: "yyyy/MM/dd",
    views: ['Day', 'Week', 'WorkWeek', 'Month'],
    selectedDate: new Date(2018, 1, 15),
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Setting the time format

Time formats is a way of representing the time value in different string formats in the Scheduler. By default, the time mode of the Scheduler can be either 12 or 24 hours format which is completely based on the locale set to the Scheduler. Since the default locale value of the Scheduler is en-US, the time mode will be set to 12 hours format automatically. You can also customize the format by using the timeFormat property. To know more about the time format standards, refer to the Date and Time Format section.

The following example demonstrates the Scheduler component in 24 hours format.

import { Schedule, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';

Schedule.Inject(Day, Week, WorkWeek, Month);
let scheduleObj: Schedule = new Schedule({
    height: '550px',
    timeFormat: 'HH:mm',
    views: ['Day', 'Week', 'WorkWeek', 'Month'],
    selectedDate: new Date(2018, 1, 15),
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Note: timeFormat property only accepts the valid time format’s.

Displaying Scheduler in RTL mode

The Scheduler layout and its behavior can be changed as per the common RTL (Right to Left) conventions by setting enableRtl to true. By doing so, the Scheduler will display its usual layout from right to left. It’s default value is false.

import { Schedule, Day, Week, WorkWeek} from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';

Schedule.Inject(Day, Week, WorkWeek);
let scheduleObj: Schedule = new Schedule({
    height: '550px',
    enableRtl: true,
    selectedDate: new Date(2018, 1, 15),
    views: ['Day', 'Week', 'WorkWeek'],
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');
