var dropzone = document.getElementById('dropzone');
var draggable = document.getElementById('draggable');
draggable.addEventListener('dragstart', onDragStart, false);
dropzone.ondragover = function(e){e.preventDefault(); }
dropzone.ondrop = function(e){ onDragOver(e); }
function onDragStart(event) {
event.dataTransfer.setData('text/html', null); //cannot be empty string
}
function onDragOver(event) {
var counter = document.getElementById('counter');
counter.innerHTML = parseInt(counter.innerHTML) + 1;
