Control Initialization

The JavaScript (ES5) Rating control 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-inputs\dist\global\ej2-inputs.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-inputs\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.

        <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
   </head>
   <body>
   </body>
  </html>

Step 5: Now, add the Rating element and initiate the JavaScript (ES5) Rating control in the index.html by using following code

        <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>

        <!-- JavaScript (ES5) Rating's control style -->
        <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

        <!-- JavaScript (ES5) Rating's dependency global script -->
        <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
        <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>

        <!-- JavaScript (ES5) Rating's control global script -->
        <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
   </head>
   <body>
        <!-- Add the HTML <input> element  -->
        <div class='wrap'>
           <input id="rating"/>
        </div>
        <script>
            // initialize Rating control
            var Rating = new ej.inputs.Rating({}, "#rating");
        </script>
   </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript (ES5) Rating control.

Step 1: Create an app folder quickstart for getting started.

Step 2: The JavaScript (ES5) control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: https://cdn.syncfusion.com/ej2/21.1.35/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Control Script: https://cdn.syncfusion.com/ej2/21.1.35/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Dependency Styles: https://cdn.syncfusion.com/ej2/21.1.35/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

Control Styles: https://cdn.syncfusion.com/ej2/21.1.35/{PACKAGE_NAME}/styles/material.css

Example:

Script: https://cdn.syncfusion.com/ej2/21.1.35/ej2-inputs/dist/global/ej2-inputs.min.js

Styles: https://cdn.syncfusion.com/ej2/21.1.35/ej2-inputs/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 Rating element and initiate the JavaScript (ES5) Rating control in the index.html by using following code.

        </div>
        <script>
            ej.base.enableRipple(true);

            // initialize Rating control
            var rating = new ej.inputs.Rating({});

            // Render initialized Rating.
            rating.appendTo('#rating');
