如何使用Angular 7生成PDF？

npm install jspdf --save
npm install html2canvas --save

import * as jsPDF from 'jspdf';
import html2canvas from 'html2canvas';

generatePDF() {
  const DATA = document.getElementById('contentToConvert'); // contentToConvert 为你想转换为PDF的HTML元素的ID
  html2canvas(DATA).then(canvas => {
    const imgData = canvas.toDataURL('image/png');
    const imgWidth = 210;
    const pageHeight = 295;
    const imgHeight = (canvas.height * imgWidth) / canvas.width;
    let heightLeft = imgHeight;

    const doc = new jsPDF('p', 'mm', 'a4');

    const position = 0;

    doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
    heightLeft -= pageHeight;

    while (heightLeft >= 0) {
      position = heightLeft - imgHeight;
      doc.addPage();
      doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
      heightLeft -= pageHeight;
    }

    doc.save('demo.pdf'); // 下载生成的PDF文件
  });
}

<div id="contentToConvert">
  <!-- 你想转换为PDF的内容 -->
</div>
<button (click)="generatePDF()">生成PDF</button>
