window.onload = function() {
				var lastTouchEnd = 0;
				document.addEventListener('touchstart'.function(event) {
					if (event.touches.length > 1) { event.preventDefault(); }});document.addEventListener('touchend'.function(event) {
					var now = (new Date()).getTime();
					if (now - lastTouchEnd <= 300) {
						event.preventDefault();
					}
					lastTouchEnd = now;
				}, false);
				document.addEventListener('gesturestart'.function(event) {
