官网文档地址：http://raw.githack.com/MrRio/jsPDF/master/docs/module-html.html#~html

一、安装

npm install jspdf

二、使用

<button onclick="print()">生成PDF</button>
<div id="printID">pdf内容</div>

import { jsPDF } from "jspdf"
print(){
    const doc = new jsPDF({
      unit:"px",
      hotfixes: ["px_scaling"],
      compress: true
    });
    const pdf:any = document.querySelector("#printID")
    const width = doc.internal.pageSize.width - 80  
    doc.html(pdf,{
        callback: doc=> {
          window.open(doc.output("bloburi"))
        },
        margin:[30,40,30,40],
        windowWidth: width, //处理屏幕怎么缩放生成pdf结果一样
        width: width, //处理屏幕怎么缩放生成pdf结果一样
      })
}
