安装依赖
1. npm install --save html2canvas  // 作用是html转图片
2. npm install jspdf --save  // 再将图片转为pdf

 - 二、局部方法
 
一、全局方法 (无论哪个页面都可调用)
1、新建一个htmlToPdf.js文件,拷入以下代码
import html2Canvas from 'html2canvas'
import JsPDF from 'jspdf'
export default{
  install (Vue, options) {
    Vue.prototype.getPdf = function (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')
      }
      )
    }
  }
}如图:
2、main.js引入
import htmlToPdf from './htmlToPdf';//路径根据自己的js文件来引入
Vue.use(htmlToPdf);
3、事件
 给需要生成pdf的盒子设置id:pdfDom
 给按钮一个全局事件方法getPdf('个人征信报告'),参数是文件名

二、局部方法
1、组件内引入
import html2Canvas from 'html2canvas'
import JsPDF from 'jspdf'
2、事件调用
methods: {
    //导出pdf
    getPdf(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')
      })
    }
  }
