我能够得到jsPDF打印动态创建的表从一个div。

$(document).ready(function() {

        $("#pdfDiv").click(function() {

    var pdf = new jsPDF('p','pt','letter');
    var specialElementHandlers = {
    '#rentalListCan': function (element, renderer) {
        return true;
        }
    };

    pdf.addHTML($('#rentalListCan').first(), function() {
        pdf.save("caravan.pdf");
    });
    });
});

工作伟大的Chrome和Firefox…格式在IE中都被放大了。

我还列出了以下内容:

<script src="js/jspdf.js"></script>
    <script src="js/jspdf.plugin.from_html.js"></script>
    <script src="js/jspdf.plugin.addhtml.js"></script>
    <script src="//mrrio.github.io/jsPDF/dist/jspdf.debug.js"></script>
    <script src="http://html2canvas.hertzen.com/build/html2canvas.js"></script>
    <script type="text/javascript" src="./libs/FileSaver.js/FileSaver.js"></script>
    <script type="text/javascript" src="./libs/Blob.js/Blob.js"></script>
    <script type="text/javascript" src="./libs/deflate.js"></script>
    <script type="text/javascript" src="./libs/adler32cs.js/adler32cs.js"></script>

    <script type="text/javascript" src="js/jspdf.plugin.addimage.js"></script>
    <script type="text/javascript" src="js/jspdf.plugin.sillysvgrenderer.js"></script>
    <script type="text/javascript" src="js/jspdf.plugin.split_text_to_size.js"></script>
    <script type="text/javascript" src="js/jspdf.plugin.standard_fonts_metrics.js"></script>

下面的方法对我的案例很有效。

隐藏页面的其他部分，如下例所示

@media print{
    body{
        -webkit-print-color-adjust: exact; // if you want to enable graphics
        color-adjust: exact !important; // if you want to enable graphics
        print-color-adjust: exact !important; // if you want to enable graphics
       
        * {
            visibility: hidden;
            margin:0;
            padding:0
        }
        .print_area, .print_area *{
            visibility: visible;
        }
        .print_area{
            margin: 0;
            align: center;
        }
        .pageBreak { 
           page-break-before : always; // If you want to skip next page
           page-break-inside: avoid;  // If you want to skip next page
         }
      }
    @page {
        size: A4; margin:0mm; // set page layout
        background-color: #fff;
    }
}

使用javascript的print函数来打印执行。

<button onclick="window.print()">Print</button>

如果你需要下载一个特定页面的PDF文件，只需添加这样的按钮

<h4 onclick="window.print();"> Print </h4>

使用window.print()打印整个页面，而不仅仅是一个div

我使用JSPDF和html2canvas进行CSS渲染，我导出特定div的内容，因为这是我的代码

$(document).ready(function () {
    let btn=$('#c-oreder-preview');
    btn.text('download');
    btn.on('click',()=> {

        $('#c-invoice').modal('show');
        setTimeout(function () {
            html2canvas(document.querySelector("#c-print")).then(canvas => {
                //$("#previewBeforeDownload").html(canvas);
                var imgData = canvas.toDataURL("image/jpeg",1);
                var pdf = new jsPDF("p", "mm", "a4");
                var pageWidth = pdf.internal.pageSize.getWidth();
                var pageHeight = pdf.internal.pageSize.getHeight();
                var imageWidth = canvas.width;
                var imageHeight = canvas.height;

                var ratio = imageWidth/imageHeight >= pageWidth/pageHeight ? pageWidth/imageWidth : pageHeight/imageHeight;
                //pdf = new jsPDF(this.state.orientation, undefined, format);
                pdf.addImage(imgData, 'JPEG', 0, 0, imageWidth * ratio, imageHeight * ratio);
                pdf.save("invoice.pdf");
                //$("#previewBeforeDownload").hide();
                $('#c-invoice').modal('hide');
            });
        },500);

        });
});

不满意html2canvas的渲染和缺乏现代CSS3/JS和打印特定的CSS支持pdfMake的过时版本的WebKit…

这是一个理论上的解决方案，它是无头的，可以忠实地渲染页面，支持分页符，页边距，不同的页面大小，并且可以自动化。你甚至可以把WebGl渲染成PDF。

Chrome有一个devtools协议…它有printtoPDF函数 摘录:https://gitlab.com/-/snippets/new 官方20k-SLOC规范:https://github.com/ChromeDevTools/devtools-protocol/blob/master/json/browser_protocol.json 你可以使用节点和https://github.com/GoogleChrome/chrome-launcher运行chrome无头…等待它渲染。 利润

在chrome_devtools协议上执行printToPDF命令:

printToPDF({
  printBackground: false,
  pageWidth: 8.5,
  pageHeight: 11,
  transferMode: "ReturnAsStream" // or ReturnAsBase64
})

使用pdfMake.js和这个Gist。

(我在这里找到了Gist和html-to-pdfmake包的链接，但我现在没有使用这个包。)

在npm安装pdfmake后，将Gist保存在htmlToPdf.js中，我这样使用它:

const pdfMakeX = require('pdfmake/build/pdfmake.js');
const pdfFontsX = require('pdfmake-unicode/dist/pdfmake-unicode.js');
pdfMakeX.vfs = pdfFontsX.pdfMake.vfs;
import * as pdfMake from 'pdfmake/build/pdfmake';
import htmlToPdf from './htmlToPdf.js';

var docDef = htmlToPdf(`<b>Sample</b>`);
pdfMake.createPdf({content:docDef}).download('sample.pdf');

备注:

My use case is to create the relevant html from a markdown document (with markdown-it) and subsequently generating the pdf, and uploading its binary content (which I can get with pdfMake's getBuffer() function), all from the browser. The generated pdf turns out to be nicer for this kind of html than with other solutions I have tried. I am dissatisfied with the results I got from jsPDF.fromHTML() suggested in the accepted answer, as that solution gets easily confused by special characters in my HTML that apparently are interpreted as a sort of markup and totally mess up the resulting PDF. Using canvas based solutions (like the deprecated jsPDF.from_html() function, not to be confused with the one from the accepted answer) is not an option for me since I want the text in the generated PDF to be pasteable, whereas canvas based solutions generate bitmap based PDFs. Direct markdown to pdf converters like md-to-pdf are server side only and would not work for me. Using the printing functionality of the browser would not work for me as I do not want to display the generated PDF but upload its binary content.
