Vue導出頁面為PDF格式的實現思路

npm install --save html2canvas 

npm install jspdf --save

// 導出頁面為PDF格式
import html2Canvas from 'html2canvas'
import JsPDF from 'jspdf'
export default{
 install (Vue, options) {
 Vue.prototype.getPdf = function () {
 var title = this.htmlTitle
 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')
 }
 )
 }
 }
}

import htmlToPdf from '@/components/utils/htmlToPdf'
Vue.use(htmlToPdf)

<div class="row" id="pdfDom" style="padding-top: 55px;background-color:#fff;">
 //給自己需要導出的ui部分.定義id為"pdfDom".此部分將就是pdf顯示的部分
</div>
<button type="button" class="btn btn-primary"v-on:click="getPdf()">導出PDF</button>

export default {
 data () {
 return {
 htmlTitle: '頁面導出PDF文件名'
 }
 }
 }
