Getting started in EJ2 TypeScript Floating action button control

3 Nov 20239 minutes to read

This section explains how to create a simple Floating action button, and configure its available functionalities in TypeScript, using Essential JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Dependencies

The list of dependencies required to use the Floating Action Button control in your application is given as follows:

|-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-base

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion CSS styles

To render Floating Action Button control, need to import Button and its dependent components styles as given below in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";

Adding Floating Action Button to the Application

Add the HTML Button tag with ID attribute as the fab to your index.html file.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
</head>

<body>
    <div>
        <!--Element to render the Floating Action Button control-->
        <button id="fab"></button>
    </div>

</body>

</html>

Then, import the Floating Action Button control in your app.ts file, and initialize it with the #fab.

[src/app/app.ts]

import { Fab } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize the Floating Action Button control.
let fab: Fab = new Fab({ content: 'Add' });

// Render initialized Floating Action Button.
fab.appendTo('#fab');

Run the application

Run the application in the browser using the following command:

npm start

The following example shows a basic Floating Action Button control.

import { Fab } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize the Floating Action Button control.
let fab: Fab = new Fab({ content: 'Add', target: '#targetElement' });

// Render initialized Floating Action Button.
fab.appendTo('#fab');

Click event

The floating action button control triggers the onclick event when you click on the floating action button. You can use this event to perform the required action.

import { Fab } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize the Floating Action Button control.
let fab: Fab = new Fab({
    iconCss: 'e-icons e-edit',
    content:'Edit' });

// Render initialized Floating Action Button.
fab.appendTo('#fab');

//onclick event handler
fab.element.onclick = (): void => {
    alert("Edit is clicked!");
};
