Getting started with JavaScript (ES5) PDF Viewer control

22 Jul 2021 / 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/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

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

Example:

Script: C:/Program Files (x86)/Syncfusion/Essential Studio/16.4.40/Essential JS 2/ej2-pdfviewer/dist/global/ej2-pdfviewer.min.js

Styles: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.40/Essential JS 2/ej2-pdfviewer/styles/material.css

Step 3: Create a folder myapp/resources and copy/paste the global scripts and styles 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/fabric.css" rel="stylesheet" type="text/css"/>

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

        <title>Essential JS 2</title>
        <!-- Essential JS 2 fabric theme -->
        <link href="resources/fabric.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 DocumentEditor's global script -->
        <script src="resources/ej2-pdfviewer.min.js" type="text/javascript"></script>
        <script src="resources/ej2.min.js" type="text/javascript"></script>
   </head>
   <body>
        <!--element which is going to render-->
            <div id='PdfViewer'>
            </div>
        <script>
            // Initialize PDF Viewer component.
            var pdfviewer = new ej.pdfviewer.PdfViewer({
                documentPath: "PDF_Succinctly.pdf",
                serviceUrl: 'http://localhost:62869/api/pdfviewer'
            });
            //PDF Viewer control rendering starts
            pdfviewer.appendTo('#PdfViewer');
        </script>
   </body>
  </html>

For PDF Viewer serviceUrl creation, follow the steps provided in the link

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

Step 1: Create an app folder myapp for the Essential JS 2 JavaScript components.

Step 2: The Essential JS 2 component’s global 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

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

Example:

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

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

Step 3: Create a HTML page (index.html) in myapp location and add the CDN link references. Now, add the Div element and initiate the Essential JS 2 PDF Viewer component in the index.html by using following code.

                ej.pdfviewer.PdfViewer.Inject(ej.pdfviewer.TextSelection, ej.pdfviewer.TextSearch, ej.pdfviewer.Navigation,ej.pdfviewer.Print);
                //PDF Viewer control rendering starts
                pdfviewer.appendTo('#PdfViewer');
            </script>
       
  <script>
var ele = document.getElementById('container');
if(ele) {
    ele.style.visibility = "visible";
 }   
        </script>
<script src="index.js" type="text/javascript"></script>
