Quasar
Swipe Touch/Mouse Action
Quasar offers full-featured Vue directives that can totally replace libraries like Hammerjs: v-touch-pan, v-touch-swipe and v-touch-hold.
These directives also work with mouse events, not only touch events, so you are able to build cool functionality for your App on desktops too.
We will be describing v-touch-swipe on the lines below.
Installation
Edit /quasar.conf.js:framework: {
directives: ['TouchSwipe']
}
Basic Usage
<div v-touch-swipe="handler">...</div> |
Handler Parameter
The handler function/method is called by the directive when a swipe touch action took place on the DOM element and it receives the following parameter:{
evt, // JS Native Event
direction, // "left", "right", "up" or "down"
duration, // Number in ms
distance // {x, y} Distance in pixels covered by swipe on horizontal and vertical
}
// example:
handler (obj) {
console.log(obj.direction) // "right"
console.log(obj.duration) // 78
console.log(obj.distance.x) // 273
}
Modifiers
| Property | Description |
|---|---|
horizontal |
Capture only horizontal swipe. |
vertical |
Capture only vertical swipe. |
up, right, down, left |
Capture swipe on the respective direction. |
noMouse |
Avoid capturing mouse events too. |
Use horizontal or vertical when you only want to capture horizontal or vertical swipes, or specify which directions are of interest:<div v-touch-swipe.horizontal="userHasSwiped">
Capturing only horizontal swipes.
</div>
<div v-touch-swipe.up.right="userHasSwiped">
Capturing only swipes to "up" or "right".
</div>
Avoid Capturing Mouse Events
When you don’t want to capture mouse actions too, use the noMouse modifier:<!--
directive won't be triggered by mouse actions;
it's exclusively triggered by touch actions now:
-->
<div v-touch-swipe.noMouse="userHasSwiped">...</div>
