现在还不可能

替代方式：将其替换为透明图像。

我的解决方法是设置一个“空”span作为拖动图像。看起来这个元素不可能真的为空，所以需要 。

let dragElement = null;

const dragStart = (event) => {
  // remove the element if it exists
  if (dragElement) {
    document.body.removeChild(dragElement);
  }

  // create an empty element
  dragElement = document.createElement("span");
  dragElement.innerHTML = " ";
  dragElement.style.position = "absolute";
  dragElement.style.left = "-1000%";

  // add the element to the dom
  document.body.appendChild(dragElement);

  //set it as the drag image
  event.dataTransfer.setDragImage(dragElement, 0, 0);
};

const dragEnd = (event) => {
  // when we have finished dragging, 
  // remove the element from the dom
  document.body.removeChild(dragElement);
  dragElement = null;
};

element.addEventListener('dragstart', (e) => {
   e.dataTransfer?.setDragImage(new Image(), 0, 0);
});
