swiped-events
A 1k 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
Usage
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.
swiped
document.addEventListener('swiped', function(e) {
console.log(e.target);
console.log(e.detail);
console.log(e.detail.dir);
});
swiped-left
document.addEventListener('swiped-left', function(e) {
console.log(e.target);
console.log(e.detail);
});
swiped-right
document.addEventListener('swiped-right', function(e) {
console.log(e.target);
console.log(e.detail);
});
swiped-up
document.addEventListener('swiped-up', function(e) {
console.log(e.target);
console.log(e.detail);
});
swiped-down
document.addEventListener('swiped-down', function(e) {
console.log(e.target);
console.log(e.detail);
});
event data
The following event data is included with every event and accessible via e.detail
{
dir: 'up',
touchType: 'direct',
xStart: 196,
fingers: 1,
xEnd: 230,
yStart: 196,
yEnd: 4
}
Configure
You can optionally configure how swiped-events works using the following HTML attributes:
Attribute | Description | Type | Default |
---|
data-swipe-threshold | Number of pixels or percent of viewport-axis a user must move before swipe fires | integer | 20 |
data-swipe-unit | Unit of the threshold (can be either "px", "vh" or "vw") | string | "px" |
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-unit="px"
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="50" data-swipe-unit="vw" data-swipe-timeout="250">
<div>Swipe me</div>
<div>or me</div>
</body>
