Swipe Event - jQuery Mobile

swipe eventversion added: 1.0

Description: Triggered when a horizontal drag of 30px or more (and less than 30px vertically) occurs within 1 second duration.

jQuery( window ).on( "swipe", function( event ) { ... } )

Triggered when a horizontal drag of 30px or more (and less than 30px vertically) occurs within 1 second duration but these can be configured:

$.event.special.swipe.scrollSupressionThreshold (default: 10px) – More than this horizontal displacement, and we will suppress scrolling.
$.event.special.swipe.durationThreshold (default: 1000ms) – More time than this, and it isn't a swipe.
$.event.special.swipe.horizontalDistanceThreshold (default: 30px) – Swipe horizontal displacement must be more than this.
$.event.special.swipe.verticalDistanceThreshold (default: 30px) – Swipe vertical displacement must be less than this.

The swipe event can also be extend to add your own logic or functionality. The following methods can be extended:

$.event.special.swipe.start Default:

function( event ) {
  var data = event.originalEvent.touches ?
      event.originalEvent.touches[ 0 ] : event;
  return {
      time: ( new Date() ).getTime(),
      coords: [ data.pageX, data.pageY ],
      origin: $( event.target )
    };
}

This method recieves a touchstart event and returns an object of data about the starting location.

$.event.special.swipe.stop Default:

function( event ) {
  var data = event.originalEvent.touches ?
      event.originalEvent.touches[ 0 ] : event;
  return {
      time: ( new Date() ).getTime(),
      coords: [ data.pageX, data.pageY ]
    };
}

This method recieves a touchend event and returns an object of data about the ending location.

$.event.special.swipe.handleSwipe Default:

function( start, stop ) {
  if ( stop.time - start.time < $.event.special.swipe.durationThreshold &&
    Math.abs( start.coords[ 0 ] - stop.coords[ 0 ] ) > $.event.special.swipe.horizontalDistanceThreshold &&
    Math.abs( start.coords[ 1 ] - stop.coords[ 1 ] ) < $.event.special.swipe.verticalDistanceThreshold ) {
 
    start.origin.trigger( "swipe" )
      .trigger( start.coords[0] > stop.coords[ 0 ] ? "swipeleft" : "swiperight" );
  }
}

This method recieves the start and stop objects and handles the logic for and triggering for the swipe events.
