Finger

Swipe/flick physics for touch devices. Usage:

var finger = Finger(element, options)

The element must be a container that contains another slidecontainer. Example markup:

<div class="container">
  <div class="slides">
    <div class="slide"></div>
    <div class="slide"></div>
  </div>
</div>

All CSS must be added manually. Finger implemenets the ainojs-events interface. Example:

// callback for each change:
finger.on('change', function(e) {
  console.log(e.value) // index value from 0-[length]
  console.log(e.position) // position value
  this.inner.style.left = e.position + 'px'
})

// callback for animation complete:
finger.on('complete', function(e) {
  console.log(e.index) // index value from 0-[length]
})

As per 1.2, Finger does not add any requestframe, so you can control it yourself for performance optimizations. The run method calculates the animation and returns a boolean. if the boolean is true, then you can call the run method again in your animation loop. Example:

(function loop() {
  finger.run() && window.requestAnimationFrame(loop)
})

Options:

• start (0) - starting point
• duration (600) - animation duration in ms
• dbltap (true) - set to false for faster tap event if doubletap is not used
• mouse (true) - enable mouse interactions
• items (null) - manually set number of items to swipe
• vertical (false) - enables vertical swipe instead of horizontal

Events:

• change - triggers if a change has been detected frame. Event object: value and position
• page - triggers if a page change will happen, before the animation is complete. Event object: index
• complete - triggers when animation is complete. Event object: index
• tap - triggers when a tap is detected. Event object: target
• dbltap - triggers when a doubbletap is detected. Event object: target
