10 Feb 202611 minutes to read
This section explains the steps required to create a simple Essential® JS 2 Button and demonstrate the basic usage of the Button control in a JavaScript application.
Dependencies
The list of dependencies required to use the Button component in your application is given below:
|-- @syncfusion/ej2-buttons
|-- @syncfusion/ej2-baseSetup for local environment
Refer to the following steps to set up your local environment.
Step 1: Create a root folder named my-app for your application.
Step 2: Create a my-app/resources folder to store local scripts and styles files.
Step 3: Open Visual Studio Code and create my-app/index.js and my-app/index.html files to initialize the Essential® JS 2 Button control.
Adding Syncfusion® resources
The Essential® JS 2 Button control can be initialized by using either of the following ways.
- Using local script and style.
- Using CDN link for script and style.
Using local script and style references in a HTML page
Step 1: Create an app folder quickstart for getting started.
Step 2: Obtain 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.jsControl Script:
**(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\dist\global\{PACKAGE_NAME}.min.jsDependency Styles:
**(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\styles\material.cssControl 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.jsControl Script:
C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-buttons\dist\global\ej2-buttons.min.jsDependency Styles:
C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\styles\material.cssControl Styles:
C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-buttons\styles\material.css
The following 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.jsStyles:
**(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\material.css
Use the Custom Resource Generator (CRG) online web tool to generate custom scripts and styles for specific controls. This tool is useful for combining 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 and add the Essential® JS 2 script and style references.

</html>Step 5: Add the Button element and initialize the Syncfusion® JavaScript (ES5) Button control in ~/quickstart/index.html using the following code:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2</title>
<!-- Essential JS 2 Base's material theme (Dependency Styles) -->
<link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
<!-- Essential JS 2 Button's material theme (Control Styles) -->

<!-- Essential JS 2 Base's global script (Dependency Script) -->
<script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
<!-- Essential JS 2 Button's global script (Control Script) -->
<script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
</head>
<body>
<!-- Add the HTML <button> element -->
<button id="element">Button</button>
<script>
// initialize button control
var button = new ej.buttons.Button();
// Render initialized button.
button.appendTo('#element')
</script>
</body>
</html>Step 6: Run the index.html in a web browser to render the Syncfusion® JavaScript Button control.
Using CDN link for script and style reference
Step 1: Create an app folder quickstart for getting started.
Step 2: The Essential® JS 2 controls’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.jsControl Script:
https://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.jsDependency Styles:
https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.cssControl Styles:
https://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css
Example:
Script:
https://cdn.syncfusion.com/ej2/ej2-buttons/dist/global/ej2-buttons.min.jsStyles:
https://cdn.syncfusion.com/ej2/ej2-buttons/styles/material.css
Step 3: Create an HTML page (index.html) at ~/quickstart/index.html and add the CDN link references. Add the Button element and initialize the Syncfusion® JavaScript (ES5) Button control in index.html using the following code:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2</title>
<!-- Essential JS 2 Base's material theme (Dependency Styles) -->
<link href="https://cdn.syncfusion.com/ej2/ej2-base/styles/material.css" rel="stylesheet" type="text/css"/>
<!-- Essential JS 2 Button's material theme (Control Styles) -->
<link href="https://cdn.syncfusion.com/ej2/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css"/>
<!-- Essential JS 2 Base's global script (Dependency Script) -->
<script src="https://cdn.syncfusion.com/ej2/ej2-base/dist/global/ej2-base.min.js" type="text/javascript"></script>
<!-- Essential JS 2 Button's global script (Control Script) -->
<script src="https://cdn.syncfusion.com/ej2/ej2-buttons/dist/global/ej2-buttons.min.js" type="text/javascript"></script>
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>
<body>
<!-- Add the HTML <button> element -->
<button id="element">Button</button>
<script>
ej.base.enableRipple(true);
// initialize button control
var button = new ej.buttons.Button({ content: 'Button' });
// Render initialized button.
button.appendTo('#element')
</script>
</body>
</html>Step 4: Run the index.html in a web browser to render the Syncfusion® JavaScript Button control.
Change Button type
To change the default Button to flat Button, set the cssClass property to e-flat.
