vue專案轉換成pdf檔案(簡單易懂)
1,新增兩個模組html2canvas和jspdf
(1)npm install --save html2canvas(將頁面html轉換成圖片)
(2)npm install --save jspdf(將圖片生成pdf)
2,建立一個htmlToPdf.js檔案在指定位置.我個人習慣放在('src/components/utils/htmlToPdf.js'),內容如下
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,在main.js中使用我們定義的函式檔案。
import htmlToPdf from '@/components/utils/htmlToPdf'
Vue.use(htmlToPdf)
4,在某個路由中新增
<div class="row" id="pdfDom">
這裡邊的內容就是pdf的內容
</div>
<button type="button" @click="getPdf()">匯出PDF</button>
data () {
return {
htmlTitle:"qwerdf"//這個是pdf檔案的名字
}
}
