首先安装 html2Canvas 和 jspdf
npm i html2canvas -S
npm i jspdf -S
然后在vue页面引入
import html2Canvas from 'html2canvas'
import JsPDF from 'jspdf'
最后实现:
html2Canvas(document.querySelector('.hello'), { allowTaint: true }).then(function (canvas) { //.hello是你要导出的范围 let contentWidth = canvas.width let contentHeight = canvas.height let pageHeight = contentWidth / 592.28 * 841.89 let leftHeight = contentHeight let position = 0 let imgWidth = 595.28 let imgHeight = 592.28 / contentWidth * contentHeight let pageData = canvas.toDataURL('image/jpeg', 1.0) let PDF = new JsPDF('', 'pt', 'a4') if (leftHeight < pageHeight) { PDF.addImage(pageData, 'JPEG', 0, 0, imgWidth, imgHeight) } else { while (leftHeight > 0) { PDF.addImage(pageData, 'JPEG', 0, position, imgWidth, imgHeight) leftHeight -= pageHeight position -= 841.89 if (leftHeight > 0) { PDF.addPage() } } } PDF.save('earth.pdf') })
