}
function allowDrag(ev) {
if (true) {
ev.dataTransfer.dropEffect = 'copy';
ev.preventDefault();
}
}
function handleDrop(ev) {
ev.preventDefault();
hideDropZone();
alert('This is Drop!');
}
window.addEventListener('dragenter', function(ev) {
displayDropZone();
});
myDrop.addEventListener('dragenter', allowDrag);
myDrop.addEventListener('dragover', allowDrag);
