Localization in Vue Schedule component

28 Mar 202324 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 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 is 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.vue file. To import JSON data, you 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 shown in the following code 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-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
        "@syncfusion/ej2-schedule": "syncfusion:ej2-schedule/dist/ej2-schedule.umd.min.js",
        "@syncfusion/ej2-calendars": "syncfusion:ej2-calendars/dist/ej2-calendars.umd.min.js",
        "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
        "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
        "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
        "@syncfusion/ej2-navigations": "syncfusion:ej2-navigations/dist/ej2-navigations.umd.min.js",
        "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
        "@syncfusion/ej2-dropdowns": "syncfusion:ej2-dropdowns/dist/ej2-dropdowns.umd.min.js",
        "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.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 cultures from the installed location to app.vue file as given in the following code example.

    //import the loadCldr from ej2-base
     import { loadCldr} from '@syncfusion/ej2-base';
  
    loadCldr(
       require('cldr-data/supplemental/numberingSystems.json'),
       require('cldr-data/main/fr-CH/ca-gregorian.json'),
       require('cldr-data/main/fr-CH/numbers.json'),
       require('cldr-data/main/fr-CH/timeZoneNames.json')
     );

• Set the culture to Scheduler by using the locale property.

app.vue

<template>
    <div id='app'>
     <div id='container'>
      <ejs-schedule :locale = 'locale' height='550px' :selectedDate='selectedDate' :eventSettings='eventSettings'>
           <e-views>
              <e-view option='Day'></e-view>
              <e-view option='Week'></e-view>
              <e-view option='WorkWeek'></e-view>
              <e-view option='Month'></e-view>
            </e-views>
         </ejs-schedule>
        </div>
      </div>
</template>
<script>
    import Vue from 'vue';
    import { scheduleData } from './datasource.js';
    import { loadCldr } from '@syncfusion/ej2-base';
    import { SchedulePlugin, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-vue-schedule';
    import * as numberingSystems from './numberingSystems.json';
    import * as gregorian from './ca-gregorian.json';
    import * as numbers from './numbers.json';
    import * as timeZoneNames from './timeZoneNames.json';

    Vue.use(SchedulePlugin);
    loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);
    export default {
        data () {
            return {
               height: '550px',
               locale: 'fr-CH',
               selectedDate: new Date(2018, 0, 15),
               eventSettings: { dataSource: scheduleData }
            }
        },
        provide: {
            schedule: [Day, Week, WorkWeek, Month]
        }
    }

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.

app.vue

<template>
    <div id='app'>
     <div id='container'>
      <ejs-schedule height='550px' :selectedDate='selectedDate' :eventSettings='eventSettings'>
           <e-views>
              <e-view option='Day'></e-view>
              <e-view option='Week'></e-view>
              <e-view option='WorkWeek'></e-view>
              <e-view option='Month'></e-view>
            </e-views>
         </ejs-schedule>
        </div>
      </div>
</template>
<script>
    import Vue from 'vue';
    import { scheduleData } from './datasource.js';
    import { L10n, loadCldr, setCulture } from '@syncfusion/ej2-base';
    import { SchedulePlugin, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-vue-schedule';
    import * as localeText from './locale.json';
    import * as numberingSystems from './numberingSystems.json';
    import * as gregorian from './ca-gregorian.json';
    import * as numbers from './numbers.json';
    import * as timeZoneNames from './timeZoneNames.json';

    Vue.use(SchedulePlugin);
    L10n.load(localeText);
    loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);
    setCulture('fr-CH');

    export default {
        data () {
            return {
               height: '550px',
               selectedDate: new Date(2018, 0, 15),
               eventSettings: { dataSource: scheduleData }
            }
        },
        provide: {
            schedule: [Day, Week, WorkWeek, Month]
        }
    }
</script>
<style>

            "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.

app.vue

<template>
    <div id='app'>
     <div id='container'>
      <ejs-schedule :dateFormat = 'dateFormat' height='550px' :selectedDate='selectedDate' :eventSettings='eventSettings'>
           <e-views>
              <e-view option='Day'></e-view>
              <e-view option='Week'></e-view>
              <e-view option='WorkWeek'></e-view>
              <e-view option='Month'></e-view>
            </e-views>
         </ejs-schedule>
        </div>
      </div>
</template>
<script>
    import Vue from 'vue';
    import { scheduleData } from './datasource.js';
    import { SchedulePlugin, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-vue-schedule';

    Vue.use(SchedulePlugin);

    export default {
        data () {
            return {
               height: '550px',
               dateFormat: 'yyyy/MM/dd',
               selectedDate: new Date(2018, 0, 15),
               eventSettings: { dataSource: scheduleData }
            }
        },
        provide: {
            schedule: [Day, Week, WorkWeek, Month]
        }
    }

  @import "../../node_modules/@syncfusion/ej2-vue-schedule/styles/material.css";
</style>

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.

app.vue

<template>
    <div id='app'>
     <div id='container'>
      <ejs-schedule :timeFormat='timeFormat' height='550px' :selectedDate='selectedDate' :eventSettings='eventSettings'>
           <e-views>
              <e-view option='Day'></e-view>
              <e-view option='Week'></e-view>
              <e-view option='WorkWeek'></e-view>
              <e-view option='Month'></e-view>
            </e-views>
         </ejs-schedule>
        </div>
      </div>
</template>
<script>
    import Vue from 'vue';
    import { scheduleData } from './datasource.js';
    import { SchedulePlugin, Day, Week, WorkWeek, Month } from '@syncfusion/ej2-vue-schedule';

    Vue.use(SchedulePlugin);

    export default {
        data () {
            return {
               height: '550px',
               timeFormat: 'HH:mm',
               selectedDate: new Date(2018, 0, 15),
               eventSettings: { dataSource: scheduleData }
            }
        },
        provide: {
            schedule: [Day, Week, WorkWeek, Month]
        }
    }
</script>
<style>
  @import "../../node_modules/@syncfusion/ej2-base/styles/material.css";

  @import "../../node_modules/@syncfusion/ej2-vue-schedule/styles/material.css";
</style>

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.

app.vue

<template>
    <div id='app'>
     <div id='container'>
      <ejs-schedule width='100%' height='550px' :selectedDate='selectedDate' :eventSettings='eventSettings' :enableRtl='enableRtl'>
           <e-views>
              <e-view option='Day'></e-view>
              <e-view option='Week'></e-view>
              <e-view option='WorkWeek'></e-view>
            </e-views>
         </ejs-schedule>
        </div>
      </div>
</template>
<script>
    import Vue from 'vue';
    import { scheduleData } from './datasource.js';
    import { SchedulePlugin, Day, Week, WorkWeek } from '@syncfusion/ej2-vue-schedule';

    Vue.use(SchedulePlugin);

    export default {
        data () {
            return {
               enableRtl: true,
               selectedDate: new Date(2018, 0, 15),
               eventSettings: { dataSource: scheduleData }
            }
        },
        provide: {
            schedule: [Day, Week, WorkWeek]
        }
    }
