先下载所需依赖
npm install --save html2canvas npm install jspdf --save
关键代码如下:
getPdf () { var title = this.title; html2Canvas(document.querySelector('#pdfDom'), { allowTaint: true }).then(function (canvas) { 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(title + '.pdf') } ) },
#pdfDom 为所需下载的起使位置
