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.

Basic Usage

<div v-touch-swipe="handler">...</div>
// "handler" is a Function which receives an Object as parameter

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

Use horizontal or vertical when you only want to capture horizontal or vertical swipes.

<div v-touch-swipe.horizontal="userHasSwiped">...</div>

NOTE
The directive allows vertical scroll when capturing only horizontal swipes.

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>
