2 Jun 20238 minutes to read

This section explains how to create a simple Calendar and how to configure the Calendar component.

Dependencies

The list of dependencies required to use the Calendar component in your application is given below:

|-- @syncfusion/ej2-calendars
  |-- @syncfusion/ej2-base
  |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-splitbuttons
  |-- @syncfusion/ej2-lists
  |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-buttons

Set up your development environment

To start the Calendar component, clone the Essential JS 2 quickstart application, and install the packages using the following commands.

git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

The application is preconfigured with common settings (src/styles/styles.css, src/system.config.js ) to start all Essential JS 2 components.

Refer to the Calendar component dependencies in system.config.js configuration file.

[src/system.config.js]

System.config({
    paths: {
        'npm:': './node_modules/',
        '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-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
        "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
        "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
        "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
        "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
        "@syncfusion/ej2-calendars": "syncfusion:ej2-calendars/dist/ej2-calendars.umd.min.js",
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');

Adding Style sheet to the Application

To render Calendar component, need to import Calendar and its dependent components styles as given below in style.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-calendars/styles/material.css";

If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

Add Calendar to the application

Add the HTML div tag with an ID attribute as the element to your index.html file.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 Calendar component</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

    <!--Style reference from app-->
    <link href="/styles/styles.css" rel="stylesheet" />

    <!--System js reference and configuration-->
    <script src="node_modules/systemjs/dist/system.src.js" type="text/javascript"></script>
    <script src="system.config.js" type="text/javascript"></script>
</head>

<body>
    <div style="margin: 50px;">
        <!--Element which is going to render the Calendar-->
        <div id="element"></div>
    </div>

</body>

</html>

Then, import the Calendar component to your app.ts file, and initialize it with the #element
[src/app/app.ts].

import { Calendar } from '@syncfusion/ej2-calendars';
//Initialize calendar component.
let calendarObject: Calendar = new Calendar();
//Render initialized calendar.
calendarObject.appendTo('#element');

Run the application

Now, run the application by using the command below.

npm run start

The following example shows a basic Calendar component.

index.ts
index.html
import { Calendar, ChangedEventArgs } from '@syncfusion/ej2-calendars';
// Creates a simple calendar component.
let calendarObject: Calendar = new Calendar();
calendarObject.appendTo('#element');

    <div id='container'>
        <!--element which is going to render the Calendar-->
        <div id='element'></div>
    </div>
</body>

</html>

Setting the value, min and max dates

After rendering a simple Calendar component by following the above steps, configure the Calendar to set a value within a specific range using its value, min, and max properties.

Here the Calendar allows you to select a date within the range from 9th to 15th.

index.ts
index.html
import { Calendar, ChangedEventArgs } from '@syncfusion/ej2-calendars';

let month: number = new Date().getMonth();
let fullYear: number = new Date().getFullYear();
// Creates a calendar with min max property.
let calendarObject: Calendar = new Calendar({
    // Sets the min.
    min: new Date(fullYear, month , 9),
    //Sets the max.
    max: new Date(fullYear, month, 15),
    // Sets the value.
    value: new Date(fullYear, month , 11)
});
calendarObject.appendTo('#element');
