前言

案例一

vue-cli + vue2导出pdf
案例地址
安装依赖

# 将页面html转换成图片
npm install --save html2canvas 
# 将图片生成pdf
npm install jspdf --save

新建htmlToPdf.js

import html2Canvas from html2canvas
import JsPDF from jspdf
export default
  install (Vue) 
    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)
      
      )

项目入口main.js中导入并挂载

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

Vue.config.productionTip = false

new Vue(
  render: h => h(App)
).$mount(#app)

在根组件App.vue中测试使用

案例二

vue-cli + vue3导出pdf
案例地址
安装依赖

# 将页面html转换成图片
npm install --save html2canvas 
# 将图片生成pdf
npm install jspdf --save

新建htmlToPdf.js

import html2Canvas from html2canvas
import JsPDF from jspdf
export default 
  install(Vue, options) 
    Vue.config.globalProperties.getPdf = function () 
      var title = this.htmlTitle
      console.log(options)
      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)
      )
    
  ,

项目入口main.js中导入并挂载

import  createApp  from vue
import App from ./App.vue
import htmlToPdf from @/components/utils/htmlToPdf

const app = createApp(App)
app.use(htmlToPdf)
app.mount("#app")
