A 0.7k script that adds swiped-left, swiped-right, swiped-up and swiped-down events to the DOM using CustomEvent and pure JS. Based on the StackOverflow thread Detect a finger swipe through JavaScript on the iPhone and Android
Add swiped-events.min.js to your page and start listening for swipe events. Events bubble, so you can addEventListener at document level, or on individual elements.
document.addEventListener('swiped', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail.dir); // swipe direction
});document.addEventListener('swiped-left', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // event data { dir: 'left', xStart: 196, xEnd: 230, yStart: 196, yEnd: 4 }
});document.addEventListener('swiped-right', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // event data { dir: 'right', xStart: 196, xEnd: 230, yStart: 196, yEnd: 4 }
});document.addEventListener('swiped-up', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // event data { dir: 'up', xStart: 196, xEnd: 230, yStart: 196, yEnd: 4 }
});document.addEventListener('swiped-down', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // event data { dir: 'down', xStart: 196, xEnd: 230, yStart: 196, yEnd: 4 }
});You can optionally configure how swiped-events works using the following HTML attributes:
| Attribute | Description | Type | Default |
|---|---|---|---|
data-swipe-threshold |
Number of pixels a user must move before swipe fires | integer | 20 |
data-swipe-timeout |
Number of milliseconds from touchstart to touchend |
integer | 500 |
data-swipe-ignore |
If true, swipe events on this element are ignored | boolean | false |
If you do not provide any attributes, it assumes the following:
<div data-swipe-threshold="20"
data-swipe-timeout="500"
data-swipe-ignore="false">
Swiper, get swiping!
</div>To set defaults application wide, set config attributes on a parent/topmost element:
<body data-swipe-threshold="100" data-swipe-timeout="250">
<div>Swipe me</div>
<div>or me</div>
</body>- Fork it!
