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); // element that was swiped
console.log(e.detail); // see event data below
console.log(e.detail.dir); // swipe direction
});swiped-left
document.addEventListener('swiped-left', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // see event data below
});swiped-right
document.addEventListener('swiped-right', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // see event data below
});swiped-up
document.addEventListener('swiped-up', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // see event data below
});swiped-down
document.addEventListener('swiped-down', function(e) {
console.log(e.target); // element that was swiped
console.log(e.detail); // see event data below
});event data
The following event data is included with every event and accessible via e.detail
{
dir: 'up', // swipe direction (up,down,left,right)
touchType: 'direct', // touch type (stylus,direct) - stylus=apple pencil and direct=finger
xStart: 196, // x coords of swipe start
fingers: 1, // number of fingers used
xEnd: 230, // x coords of swipe end
yStart: 196, // y coords of swipe start
yEnd: 4 // y coords of swipe end
}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>
