前端PDF导出，使用html2Canvas和jsPDF插件

import html2Canvas from "html2canvas";
import jsPDF from "jspdf";
export function downloadPDF(dom, filename) {const scale = 2;window.pageYOffset = 0;// 滚动到顶部，避免打印不全document.documentElement.scrollTop = 0;document.body.scrollTop = 0;html2Canvas(dom, {allowTaint: true, scale, }).then((canvas) => {console.log("canvas", canvas);const contentWidth = canvas.width / scale;const contentHeight = canvas.height / scale;const pdf = new jsPDF("", "pt", [contentWidth, contentHeight]);const pageData = canvas.toDataURL("image/jpeg", 1.0);pdf.addImage(pageData, "JPEG", 0, 0, contentWidth, contentHeight);pdf.save(`${filename}.pdf`);});
}
