我可以使用javascript将iframe导出为pdf吗？

function exportIframeAsPdf() {
  const iframe = document.getElementById('your-iframe-id');
  const pdfName = 'exported-pdf';

  iframe.contentWindow.print();

  // Create a canvas element
  const canvas = document.createElement('canvas');
  const iframeWindow = iframe.contentWindow;
  const iframeDocument = iframe.contentDocument || iframeWindow.document;

  const iframeBody = iframeDocument.body;

  // Set canvas size to be the same as iframe
  canvas.width = iframeBody.offsetWidth;
  canvas.height = iframeBody.offsetHeight;

  // Get canvas context
  const canvasContext = canvas.getContext('2d');

  // Wait for iframe content to load
  iframeWindow.onload = () => {
    setTimeout(() => {
      // Draw iframe content to the canvas
      canvasContext.drawImage(
        iframeWindow,
        0,
        0,
        iframeBody.offsetWidth,
        iframeBody.offsetHeight,
        0,
        0,
        iframeBody.offsetWidth,
        iframeBody.offsetHeight
      );

      // Convert canvas to data URL
      const dataUrl = canvas.toDataURL('image/jpeg');

      // Create a PDF document
      const pdfDoc = new jsPDF();

      // Add image to the PDF document
      pdfDoc.addImage(dataUrl, 'JPEG', 0, 0, iframeBody.offsetWidth, iframeBody.offsetHeight);

      // Save the PDF document
      pdfDoc.save(`${pdfName}.pdf`);
    }, 1000);
  };
}

// Call the function to export iframe as PDF
exportIframeAsPdf();
