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
