Getting Started with JavaScript(ES5)

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Component Initialization

Create an app folder myapp in local machine to initialize Essential JS 2 JavaScript components.

Using either of the following way to refer the required script and styles.

  • Using local script and style references in a HTML page.
  • Using CDN link for script and style reference.

Using local script and style references in a HTML page

Step 1: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Step 2: To render Calendar component, need to add Calendar and its dependent packages from below installed location.

Dependencies

  • ej2-base

  • ej2-buttons

  • ej2-calendars

Syntax:

package: **(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME

Example:

Package: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-base

packages: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-buttons

Package: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-calendars

Step 3: Create a folder myapp/resources and copy/paste the above mentioned packages from the above installed location to myapp/resources location.

Step 4: Create a HTML page (index.html) in myapp location and add the Essentials JS 2 script and style references.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2</title>
            <!-- Calendar and its dependent theme -->
            <link href="resources/ej2-base/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/ej2-calendars/styles/material.css" rel="stylesheet" type="text/css"/>
            <!-- Essential JS 2 Calendar's global script -->
            <script src="resources/ej2-calendars/dist/global/ej2-calendars.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

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

Step 5: Now, add the div element and initiate the Essential JS 2 Calendar component in the index.html by using following code

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
            <title>Essential JS 2 Calendar Component</title>
            <!-- Calendar and its dependent theme -->
            <link href="resources/ej2-base/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/ej2-calendars/styles/material.css" rel="stylesheet" type="text/css"/>
            <!-- Essential JS 2 Calendar's global script -->
            <script src="resources/ej2-calendars/dist/global/ej2-calendars.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> element  -->
             <div id="element"/>
            <script>
                // initialize Calendar component
                var calendar = new ej.calendars.Calendar();

                // Render initialized calendar.
                calendar.appendTo('#element')
            </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Essential JS 2 Calendar component.

Step 1: The Essential JS 2 components scripts and styles are already hosted in the below CDN link formats.

Syntax:

Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Style: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.js

Styles: http://cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css

Step 2: Have to add CDN global script and style for calender and its dependent packages in myapp/index.html like below.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
            <title>Essential JS 2 Calendar Component</title>
            <!-- Calendar and its dependent theme -->
            <link href="http://cdn.syncfusion.com/ej2/ej2-base/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="http://cdn.syncfusion.com/ej2/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css"/>
            <link href="http://cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css" rel="stylesheet" type="text/css"/>
            <!-- Essential JS 2 Calendar's global script -->
            <script src="http://cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> element  -->
             <div id="element"/>
            <script>
                // initialize Calendar component
                var calendar = new ej.calendars.Calendar();

                // Render initialized button.
                calendar.appendTo('#element')
            </script>
       </body>
  </html>

When referencing CDN links in application, always ensure the network connection will be in enabled state.

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 in the month of May 2017.
