I'm trying to make a pure Drag'n Drop with Javascript:
Two errors if I can not solve:
1 - When dragging List 2 it always places the element under the mouse and not above.
2 - When I try to get the element through Class I can not.
Obs: By Id it can drag normally.
Try this:
No drag init puts you like this:
function drag_init(elem) {
selected = elem;
y_elem = y_pos - selected.closest('ul').offsetTop;
}
And document.getElementClassName you replace with:
document.querySelectorAll('.draggable').forEach(function(el) {
el.onmousedown = function () {
drag_init(this);
return false;
};
});
