查了下網(wǎng)上的資料签夭,主要都是先將頁面轉(zhuǎn)為圖片,然后再通過圖片生成PDF的
1演侯、要先安裝兩個(gè)模塊
npm install --save html2canvas
npm install jspdf --save
2、定義一個(gè)工具類背亥,用于將頁面轉(zhuǎn)為圖片再轉(zhuǎn)為PDF
// 導(dǎo)出頁面為PDF格式
import html2Canvas from 'html2canvas'
import JsPDF from 'jspdf'
export function html2Pdf() {
var title = this.htmlTitle
html2Canvas(document.querySelector('#pdfDom'), {
allowTaint: true
}).then(function(canvas) {
const contentWidth = canvas.width
const contentHeight = canvas.height
const pageHeight = contentWidth / 592.28 * 841.89
let leftHeight = contentHeight
let position = 0
const imgWidth = 595.28
const imgHeight = 592.28 / contentWidth * contentHeight
const pageData = canvas.toDataURL('image/jpeg', 1.0)
const 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')
}
)
}
