long-press-event
A 1k script that adds a long-press event to the DOM using CustomEvent and pure JavaScript. Works in IE9+, Chrome, Firefox, Safari as well as popular mobile browsers including Cordova (Phone Gap) applications.
Defaults to 1.5 seconds but can be overridden by adding a data-long-press-delay attribute to an element.

Usage
Add the long-press-event.min.js file to your page and then listen for the event.
To listen for a long-press on any HTML element:
// the event bubbles, so you can listen at the root level
document.addEventListener('long-press', function(e) {
console.log(e.target);
});To listen for a long-press on a specific HTML element:
// grab the element
var el = document.getElementById('idOfElement');
// listen for the long-press event
el.addEventListener('long-press', function(e) {
// stop the event from bubbling up
e.preventDefault()
console.log(e.target);
});To set a custom delay and listen for a long-press:
<html>
<head>
<script src="long-press-event.js"></script>
<script>
document.addEventListener('long-press', function(e) {
console.log(e.target);
});
</script>
</head>
<body>
<div data-long-press-delay="500">Press and hold me for .5s</div>
</body>
</html>To set a default application wide data-long-press-delay, set attribute on a parent/topmost element:
<html data-long-press-delay="1500">
<head>...</head>
<body>...</body>
