Getting started with JavaScript (ES5) ListBox control

27 Jul 2021 / 4 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/15.4.30/Essential JS 2/ej2-dropdowns/dist/global/ej2-dropdowns.min.js

Styles: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-dropdowns/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/material.css" rel="stylesheet" type="text/css"/>

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

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

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

        <!-- Essential JS 2 ListBox's global script -->
        <script src="resources/ej2-dropdowns.min.js" type="text/javascript"></script>
   </head>
  <body>
       <!-- Add the HTML <input> element  -->
         <input id='listbox' />
        <script>
        // initialize ListBox component
        var listObj = new ej.dropdowns.ListBox();
        // Render initialized ListBox.
        listObj.appendTo('#listbox');
        </script>
   </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Essential JS 2 ListBox 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-dropdowns/dist/global/ej2-dropdowns.min.js

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

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

         <input id='listbox' />
        <script>
        // initialize ListBox component
        var listObj = new ej.dropdowns.ListBox();
        // Render initialized ListBox.
        listObj.appendTo('#listbox');
        </script>
   </body>
  </html>

Step 4: Now, run the index.html in web browser, it will render the Essential JS 2 ListBox component.

Binding data source

After initialization, populate the ListBox with data using the dataSource property. Here, an array of object values is passed to the ListBox component.
