使用jsPDF和html2canvas與es6

Question

我試圖用es6和jsPDF和html2canvas。

我正在導入html2canvas和jsPDF，但在addHTML 上發生錯誤時，我註釋掉生成pdf的addHTML。

任何線索是什麼問題？

謝謝。

import html2canvas from 'html2canvas'; 
 
import jsPDF from 'jspdf'; 
 

 
doc.setFontSize(40); 
 
doc.text(35, 25, "Paranyan loves jsPDF"); 
 

 
doc.addHTML(document.footer,function() { 
 
    pdf.save('web.pdf'); 
 
});

<footer> 
 
\t <p id="to-pdf">HTML content...</p> 
 
</footer>

從https://github.com/MrRio/jsPDF/issues/1225：

jsPDF要求html2canvas是窗口：

window.html2canvas = html2canvas
