这个例子效果很好。

<button onclick="genPDF()">Generate PDF</button>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script>
    function genPDF() {
        var doc = new jsPDF();
        doc.text(20, 20, 'Hello world!');
        doc.text(20, 30, 'This is client-side Javascript, pumping out a PDF.');
        doc.addPage();
        doc.text(20, 20, 'Do you like that?');
    
        doc.save('Test.pdf');
    }
</script>

你可以使用autoPrint()并将输出设置为'dataurlnewwindow'，如下所示:

function printPDF() {
    var printDoc = new jsPDF();
    printDoc.fromHTML($('#pdf').get(0), 10, 10, {'width': 180});
    printDoc.autoPrint();
    printDoc.output("dataurlnewwindow"); // this opens a new popup,  after this the PDF opens the print window view but there are browser inconsistencies with how this is handled
}

如前所述，您应该使用jsPDF和html2canvas。我还在jsPDF问题中发现了一个函数，它自动将您的pdf分割成多个页面(来源)

function makePDF() {

    var quotes = document.getElementById('container-fluid');

    html2canvas(quotes, {
        onrendered: function(canvas) {

        //! MAKE YOUR PDF
        var pdf = new jsPDF('p', 'pt', 'letter');

        for (var i = 0; i <= quotes.clientHeight/980; i++) {
            //! This is all just html2canvas stuff
            var srcImg  = canvas;
            var sX      = 0;
            var sY      = 980*i; // start 980 pixels down for every new page
            var sWidth  = 900;
            var sHeight = 980;
            var dX      = 0;
            var dY      = 0;
            var dWidth  = 900;
            var dHeight = 980;

            window.onePageCanvas = document.createElement("canvas");
            onePageCanvas.setAttribute('width', 900);
            onePageCanvas.setAttribute('height', 980);
            var ctx = onePageCanvas.getContext('2d');
            // details on this usage of this function: 
            // https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images#Slicing
            ctx.drawImage(srcImg,sX,sY,sWidth,sHeight,dX,dY,dWidth,dHeight);

            // document.body.appendChild(canvas);
            var canvasDataURL = onePageCanvas.toDataURL("image/png", 1.0);

            var width         = onePageCanvas.width;
            var height        = onePageCanvas.clientHeight;

            //! If we're on anything other than the first page,
            // add another page
            if (i > 0) {
                pdf.addPage(612, 791); //8.5" x 11" in pts (in*72)
            }
            //! now we declare that we're working on that page
            pdf.setPage(i+1);
            //! now we add content to that page!
            pdf.addImage(canvasDataURL, 'PNG', 20, 40, (width*.62), (height*.62));

        }
        //! after the for loop is finished running, we save the pdf.
        pdf.save('test.pdf');
    }
  });
}

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>

如果您想导出一个表，可以查看Shield UI Grid小部件提供的导出示例。

它是通过像这样扩展配置来实现的:

...
exportOptions: {
    proxy: "/filesaver/save",
    pdf: {
        fileName: "shieldui-export",
        author: "John Smith",
        dataSource: {
            data: gridData
        },
        readDataSource: true,
        header: {
            cells: [
                { field: "id", title: "ID", width: 50 },
                { field: "name", title: "Person Name", width: 100 },
                { field: "company", title: "Company Name", width: 100 },
                { field: "email", title: "Email Address" }
            ]
        }
    }
}
...

一种方法是使用window.print()函数。哪个不需要任何库

Pros

1.不需要外部库。

2.我们也可以只打印选定的身体部位。

3.没有css冲突和js问题。

4.html/js核心功能

简单地添加下面的代码

CSS

@media print {
        body * {
            visibility: hidden; // part to hide at the time of print
            -webkit-print-color-adjust: exact !important; // not necessary use         
               if colors not visible
        }

        #printBtn {
            visibility: hidden !important; // To hide 
        }

        #page-wrapper * {
            visibility: visible; // Print only required part
            text-align: left;
            -webkit-print-color-adjust: exact !important;
        }
    }

JS代码-调用btn点击下函数

$scope.printWindow = function () {
  window.print()
}

注意:在每个css对象中使用!important

的例子,

.legend  {
  background: #9DD2E2 !important;
}
