vue中将网页打印成pdf实例代码

整理文档，搜刮出一个vue中将网页打印成pdf的代码，稍微整理精简一下做下分享。

<template>
<div class="pdf-wrap" id="pdfWrap">
 <button v-on:click="getPdf">点击下载PDF</button>
 <div class="pdf-dom" id="pdfDom"></div>
</div>
</template>
<style lang="scss" scoped>

</style>
<script type="text/ecmascript-6">
 import html2Canvas from '@/components/html2canvas.js'
 import JsPDF from '@/components/jsPdf.debug.js'

 export default {
 methods: {
 getPdf: function () {
 let _this = this
 let pdfDom = document.querySelector('#pdfDom')
 html2Canvas(pdfDom, {
 onrendered: 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(_this.pdfData.title + '.pdf')
 }
 })
 html2Canvas()
 },
 }
 }
</script>

需要引入

html2canvas.js'

和

jsPdf.debug.js

这两个插件库可轻松百度到。如果eslint验证报错，可在eslintignore中设置不对这两个文件进行验证。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
