You can take a look at https://github.com/parallax/jsPDF .你可以看看https://github.com/parallax/jsPDF 。
It's js library allow you to build pdf using Javascript.它的 js 库允许您使用 Javascript 构建 pdf。

Otherwise have some solutions to convert html page to pdf ( https://www.html2pdf.co.uk/ ), but I don't think it's what you are looking for.否则有一些将 html 页面转换为 pdf 的解决方案（ https://www.html2pdf.co.uk/ ），但我认为这不是你要找的。

Exemple of code using JSPDF :使用 JSPDF 的代码示例：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>


var doc = new jsPDF();
doc.text(20, 20, 'Hello world!');
doc.text(20, 30, 'This is client-side Javascript, pumping out a PDF.');

doc.save('Test.pdf');

Hope it will helps you ;)希望它会帮助你;）
