1、下載外掛

npm install html2canvas jspdf

2、utils目錄下新建 htmlToPdf.js

// 匯出頁面為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')
      })
    }
  }
}

3、main.js中引入並定義 htmlToPdf方法

// html匯出為pdf
import htmlToPdf from '@utils/htmlToPdf'
Vue.use(htmlToPdf)

4、在 xxx.vue中定義按鈕

<el-button type="primary" size="small" @click="getPdf('#pdfDom')">點選下載</el-button>

5、data中定義匯出檔名

  data() {
    return {
      htmlTitle: '待審查任務'
    }
　}

6、給需要匯出的div加上id='#pdfDom' 屬性

效果：
