有没有办法用它的内容克隆HTML5 canvas元素？

function cloneCanvas(oldCanvas) {
  // 创建一个新的canvas元素
  const newCanvas = document.createElement('canvas');

  // 设置新canvas元素的宽度和高度与原canvas元素相同
  newCanvas.width = oldCanvas.width;
  newCanvas.height = oldCanvas.height;

  // 获取原canvas元素的2D渲染上下文
  const context = oldCanvas.getContext('2d');

  // 将原canvas元素的内容绘制到新canvas元素上
  newCanvas.getContext('2d').drawImage(oldCanvas, 0, 0);

  // 返回新的canvas元素
  return newCanvas;
}

const oldCanvas = document.getElementById('myCanvas');
const newCanvas = cloneCanvas(oldCanvas);
document.body.appendChild(newCanvas);
