USAGE
Use this module in 3 different ways.
simple
Just import the minified es5 library into you're HTML document, and every element with a parameter set to data-longpress=time-in-ms will fire a "longpress"-event after clicking it the given amount of time.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<script src="./longpressbutton/dist/longpressbutton-min.js" defer></script>
<title>EXAMPLE</title>
</head>
<body>
<button data-longpress="2000">PRESS 2s</button>
</body>
</html>
Access the event by either set the onclick event directly in the html
<button data-longpress="2000" onclick="console.log('clicked!')">PRESS 2s</button>
or listen to the longpress-event in a javascript.
document.querySelector('button').addEventListener('longpress', (event) => { console.log('clicked!')});
module
If you want to pack the module with your own project, you have to import this module and call lpButton.init(). This function searches the whole document for elements with a data-longpress=time-in-ms attribute.
import {lpButton} from 'longpressbutton';
lpButton.init();
For a specific search scope, just pass the top element as argument to the init function.
lpButton.init(HTMLElement);
module with dynamic DOM-Elements
In case you have dynamic elements which are created by your script use this module class directly.
import {lpButton} from 'longpressbutton';
const customElement = document.createElement('button');
customElement.addEventListener('longpress', (event) => { cosole.log(event) });
lpButton.newButton(customElement, 1000); //returns the customElement
document.append(customElement);
Just make sure to link the longpressbutton.css.
CSS
Per default this module comes with a animation while pressing. You can specify your own stylings by overriding the classes.
Every longpress button element has a .lpb-button class and gets a child element with a .lpb-loader class. This element gets a .lpb-loading class while pressing and a .lpb-loaded class on timer expiration until a css keyframe animation ends.
