拖动HTML元素时更改光标

Question

I know there has been numerous similiar questions on stackoverflow, I've read several of them, but none provided there answers worked in my case. I want to change cursor while dragging HTML element. I tried this:

var startX = null;
var startY = null;
var element = document.getElementById('bla');

element.addEventListener('dragstart', onDragStart, true);
element.addEventListener('dragend', onDragEnd, true);
element.addEventListener('drag', onDrag, true);

function onDragStart(e){

  startX = e.screenX;
  startY = e.screenY;
  e.target.style.cursor = "move";
}

function onDrag(e){

    e.target.style.cursor = "move";
}

function onDragEnd(e){

    var style = document.defaultView.getComputedStyle(element);

  var newLeft = parseInt(style.left) + e.screenX - startX;
  var newTop = parseInt(style.top) + e.screenY - startY;

  e.target.style.left = newLeft + 'px';
  e.target.style.top = newTop + 'px';

  e.target.style.cursor = "default";
}

But it doesn't work. I have no idea why on earth e.target.style.cursor = "move" doesn't work. I tried changing it to document.body.style.cursor = "move" , but it doesn't work either. Any help with solving this problem with explanation why my code doesn't work will be greatly appreciated.

Ps. I'm looking for pure JS solution, no JQuery. Ps2. I couldn't get answers from to work in my case. And I don't want to use custom cursor images, just standard css ones.

Try to preventDefault on the other drag events. Also, you might want to consider adding a drop target that would handle dragover events.

document.addEventListener('dragover', (e) => e.preventDefault(), true)
