mobile_safari_input_touch_events.js

// Mobile Safari doesn't fire touchstart or touchend events for
// input[type=text], input[type=password], input[type=search],
// and textarea elements.

(function() {
  if (!("createTouch" in document)) return;
  var selector = "input[type=text], input[type=password], input[type=search], textarea";

  function fire(element, type, identifier) {
    var touch = document.createTouch(window, element, identifier, 0, 0, 0, 0);

    var touches = document.createTouchList(touch);
    var targetTouches = document.createTouchList(touch);
    var changedTouches = document.createTouchList(touch);

    var event = document.createEvent("TouchEvent");
    event.initTouchEvent(type, true, true, window, null, 0, 0, 0, 0, false, false, false, false,
      touches, targetTouches, changedTouches, 1, 0);
    element.dispatchEvent(event);
  }

  document.on("mouseup", selector, function(event, element) {
    var identifier = new Date().getTime();
    fire.defer(element, "touchstart", identifier);
    fire.defer(element, "touchend", identifier);
  });
})();

Yeah, it's missing exactly what I need to complete my proof of concept. Thanks for replying though. Got any more tips on where to look for more info?
