html to pdf下载在angular jspdf

Question

我已经为angular安装了jspdf。我有一些html内容要显示在模态，我需要下载在pdf。每当我下载时，我得到的是空的pdf文件下载。

downloadPdf(): void {
const data = document.getElementById('pdfData');
html2canvas(data).then(canvas => {
  const imgWidth = 150;
  const pageHeight = 200;
  const imgHeight = canvas.height * imgWidth / canvas.width;
  const heightLeft = imgHeight;
  const contentDataURL = canvas.toDataURL('image/png');
  const pdf = new jsPDF('p', 'pt', 'a4');
  const position = 0;
  pdf.addImage(contentDataURL, 'PNG', 0, position, imgWidth, imgHeight);
  pdf.save('invoice.pdf');
});

使用jspdf.html()方法代替http://raw.githack.com/MrRio/jsPDF/master/docs/module-html.html。
