click:fast - a fast click event alternative that triggers the handler much faster on touch devices (and also prevents click events on swipe/scroll).
$.event.special['click:fast'] = {
propagate: true,
add: function(handleObj) {
var getCoords = function(e) {
if ( e.touches && e.touches.length ) {
var touch = e.touches[0];
return {
x: touch.pageX,
y: touch.pageY

Stateful DOM wrapper
// example:
// var stateHandler = State(node, function(state) { this.className = state.active ? 'active' : '' })
// stateHandler.set({ active: true })
var states = {}
function State(elem, render) {
if ( states.hasOwnProperty(elem) )
return states[elem]
if ( !(this instanceof State) ) {
var instance = new State(elem, render)
