$('draggable').ontouchmove = function(e){
if(e.touches.length == 1){ // Only deal with one finger
var touch = e.touches[0]; // Get the information for finger #1
var node = touch.target; // Find the node the drag started from
node.style.position = "absolute";
node.style.left = touch.pageX -node.offsetWidth /2+ "px";
node.style.top = touch.pageX -node.offsetHeight/2+ "px";
