计算绝对位置嵌套子对象的高度

function calculateNestedHeight(parentId, childId) {
  const parent = document.getElementById(parentId);
  const child = document.getElementById(childId);

  function getHeight(element) {
    const { clientHeight, scrollHeight } = element;
    return Math.max(clientHeight, scrollHeight);
  }

  function calculateTotalHeight(element) {
    let totalHeight = getHeight(element);

    const children = element.children;
    for (let i = 0; i < children.length; i++) {
      totalHeight += calculateTotalHeight(children[i]);
    }

    return totalHeight;
  }

  const nestedHeight = calculateTotalHeight(child);
  console.log("Nested height:", nestedHeight);
}

// 示例用法
calculateNestedHeight("parentElementId", "childElementId");
