2 Jun 202311 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.

Control Initialization

The Essential JS 2 JavaScript controls 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 quickstart for getting started.

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

Syntax:

Dependency Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\dist\global\{DEPENDENCY_PACKAGE_NAME}.min.js

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

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

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

Example:

Dependency Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\dist\global\ej2-base.min.js

Control Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-splitbuttons\dist\global\ej2-splitbuttons.min.js

Dependency Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\styles\material.css

Control Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-splitbuttons\styles\material.css

The below located script and style file contains all Syncfusion JavaScript (ES5) UI control resources in a single file.

Scripts: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\dist\ej2.min.js

Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\material.css

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls. This web tool is useful to combine the required control scripts and styles in a single file.

Step 3: Create a folder ~/quickstart/resources and copy/paste the global scripts and styles from the above installed location to ~/quickstart/resources/package corresponding package location.

Step 4: Create a HTML page (index.html) in ~/quickstart/index.html 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>
            <!-- Essential JS 2 DropDownButton's dependency style -->
            <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>

            <!-- Essential JS 2 DropDownButton's control style -->
            <link href="resources/splitbuttons/material.css" rel="stylesheet" type="text/css"/>

            <!-- Essential JS 2 DropDownButton's dependency global script -->
            <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
            <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
            <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>

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

Step 5: Now, add the DropDownButton element and initiate the Syncfusion JavaScript DropDownButton control in the index.html by using following code

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2</title>
            <!-- Essential JS 2 DropDownButton's dependency style -->
            <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>
            <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>

            <!-- Essential JS 2 DropDownButton's control style -->
            <link href="resources/splitbuttons/material.css" rel="stylesheet" type="text/css"/>

            <!-- Essential JS 2 DropDownButton's dependency global script -->
            <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
            <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
            <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>

            <!-- Essential JS 2 DropDownButton's control global script -->
            <script src="resources/splitbuttons/ej2-splitbuttons.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!--element which is going to render-->
            <button id='element'>Edit</button>
            <script>
                //Initialize action items.
                var items = [
                {
                  text: 'Cut'
                },
                {
                  text: 'Copy'
                },
                {
                  text: 'Paste'
                }];

                // initialize DropDownButton control
                var drpDownBtn = new ej.splitbuttons.DropDownButton({items: items});

                // Render initialized DropDownButton.
                drpDownBtn.appendTo('#element');
            </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript DropDownButton control.

Step 1: Create an app folder quickstart for the Essential JS 2 JavaScript controls.

Step 2: The Essential JS 2 control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

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

Dependency Styles: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

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

Example:

Script: https://cdn.syncfusion.com/ej2/ej2-splitbuttons/dist/global/ej2-splitbuttons.min.js

Styles: https://cdn.syncfusion.com/ej2/ej2-splitbuttons/styles/material.css

Step 3: Create a HTML page (index.html) in ~/quickstart/index.html location and add the CDN link references. Now, add the
DropDownButton element and initiate the Syncfusion JavaScript DropDownButton control in the index.html by using following code.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
   <head>
                
        <title>Essential JS 2</title>
        <!-- Essential JS 2 DropDownButton's dependency style -->
        <link href="https://cdn.syncfusion.com/ej2/25.1.35/ej2-base/styles/material.css" rel="stylesheet" type="text/css"/>
        <link href="https://cdn.syncfusion.com/ej2/25.1.35/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css"/>
        <link href="https://cdn.syncfusion.com/ej2/25.1.35/ej2-popups/styles/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 DropDownButton's control style -->
        <link href="https://cdn.syncfusion.com/ej2/25.1.35/ej2-splitbuttons/styles/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 DropDownButton's dependency global script -->
       <script src="https://cdn.syncfusion.com/ej2/25.1.35/ej2-base/dist/global/ej2-base.min.js" type="text/javascript"></script>
       <script src="https://cdn.syncfusion.com/ej2/25.1.35/ej2-buttons/dist/global/ej2-buttons.min.js" type="text/javascript"></script>
       <script src="https://cdn.syncfusion.com/ej2/25.1.35/ej2-popups/dist/global/ej2-popups.min.js" type="text/javascript"></script>

       <!-- Essential JS 2 DropDownButton's control global script -->
        <script src="https://cdn.syncfusion.com/ej2/25.1.35/ej2-splitbuttons/dist/global/ej2-splitbuttons.min.js" type="text/javascript"></script>
   <script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>
   <body>
        <!--element which is going to render-->
        <button id='element'>Edit</button>
        <script>
            ej.base.enableRipple(true);

            //Initialize action items.
            var items = [
            {
              text: 'Cut'
            },
            {
              text: 'Copy'
            },
            {
              text: 'Paste'
            }];

            // initialize DropDownButton control
            var drpDownBtn = new ej.splitbuttons.DropDownButton({items: items});

            // Render initialized DropDownButton.
            drpDownBtn.appendTo('#element');
        </script>
   </body>
  </html>

Step 4: Now, run the index.html in web browser, it will render the Syncfusion JavaScript DropDownButton control.
