如何访问被放入可排序的draggable元素的id

<ul id="sortableList">
  <li draggable="true" id="item1">Item 1</li>
  <li draggable="true" id="item2">Item 2</li>
  <li draggable="true" id="item3">Item 3</li>
</ul>

const sortableList = document.getElementById("sortableList");

sortableList.addEventListener("dragstart", (event) => {
  const target = event.target;
  event.dataTransfer.setData("text/plain", target.id);
});

sortableList.addEventListener("dragover", (event) => {
  event.preventDefault();
});

sortableList.addEventListener("drop", (event) => {
  event.preventDefault();
  const target = event.target;
  const id = event.dataTransfer.getData("text/plain");
  const draggedItem = document.getElementById(id);

  if (target !== draggedItem) {
    target.parentNode.insertBefore(draggedItem, target);
  }
});
