24 Jun 2022 / 3 minutes to read

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

The Essential JS 2 JavaScript components can be initialized by using either of the following ways.

  • 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: Create an app folder myapp for Essential JS 2 JavaScript components.

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

Syntax:

Script: **(installed location)**/Syncfusion/Essential Studio/JavaScript - EJ2/{RELEASE_VERSION}/Web(Essential JS 2)/JavaScript/{PACKAGE_NAME}/dist/{PACKAGE_NAME}.min.js

Styles: **(installed location)**/Syncfusion/Essential Studio/JavaScript - EJ2/{RELEASE_VERSION}/Web(Essential JS 2)/JavaScript/{PACKAGE_NAME}/styles/material.css

Example:

Script: C:/Program Files (x86)/Syncfusion/Essential Studio/JavaScript - EJ2/19.3.53/Web(Essential JS 2)/JavaScript/ej2/dist/ej2.min.js

Styles: C:/Program Files (x86)/Syncfusion/Essential Studio/JavaScript - EJ2/19.3.53/Web(Essential JS 2)/JavaScript/ej2-js-es5/styles/material.css

You can also clone the Essential JS 2 quickstart project and install necessary packages by using the following commands.

Step 3: Create a folder myapp/resources and copy/paste the scripts and styles of ej2 package 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.

        <!-- Essential JS 2 material theme -->
        <link href="resources/ej2-js-es5/styles/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 PDF Viewer's script -->
        <script src="resources/ej2.min.js" type="text/javascript"></script>
   </head>

           </div>
      </div>
      <script>
           //Initialize PDF Viewer component
           var pdfviewer = new ej.pdfviewer.PdfViewer({
                documentPath: "PDF_Succinctly.pdf",
                serviceUrl: 'https://ej2services.syncfusion.com/production/web-services/api/pdfviewer'
           });
           //PDF Viewer control rendering starts
           pdfviewer.appendTo('#PdfViewer');
