Question

我想将当前网页导出为pdf，我使用JSPDF

进行如下操作

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.4/jspdf.min.js"> </script>
        <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.js"></script>

        <script type="text/javascript">

            function getPDF()
            {

                html2canvas(document.body,{

                    onrendered: function(canvas)
                    {
                    var img = canvas.toDataURL("image/png");
                    var doc = new jsPDF();
                    var width = doc.internal.pageSize.width;    
                    var height = doc.internal.pageSize.height;


                    doc.setFont("helvetica");
                    doc.setFontType("bold");
                    doc.setFontSize(9);


                    alert(width)
                    alert(height)
                  //  pdf.addImage(img, 'JPEG', 0, 0,width,height);
                doc.addImage(img, 'JPEG', 0, 0,width,height);
                    doc.save("test.pdf");
                    }
                }

                );
            }

Answer 1

更改getPDF以获得更好的PDF格式。见addHTML source code

function getPDF() {
    var doc = new jsPDF();
    doc.addHTML(document.body, function() {
        doc.save('test.pdf')
    })
}

在javascript中将当前页面导出为pdf
