前联通大佬江哥分享的导出网页为PDF的方法,可以根据Dom节点生成想要的pdf文件
// 导出页面为PDF格式#
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')
}
)
}
}
}

该博客介绍了如何利用html2canvas和JsPDF库将网页内容转换并导出为PDF文件。通过选择DOM节点,生成canvas图片,然后将其转化为PDF格式,实现自定义页面布局的PDF生成。此方法适用于前端开发中需要网页内容离线保存的场景。
