Question

是否可以按“3 X 4”形式生成pdf？

我已尝试过如下代码，但未生成PDF，我从here下载了JSPDF.min

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="js/jspdf.min.js"></script>
<script>       
    var doc = new jsPDF();
    var specialElementHandlers = {
        '#editor': function (element, renderer) {
            return true;
        }
    };
    $('#cmd').click(function () {
        doc.fromHTML($('#content').html(), 15, 15, {
            'width': 170,
            'elementHandlers': specialElementHandlers
        });
        doc.save('sample-file.pdf');
    });

</script>

html代码

<div id="content">
<h3>Hello, this is a H3 tag</h3>    
<p>a pararaph</p>
</div>
<div id="editor"></div>
<button id="cmd">generate PDF</button>

这是我的页面中的代码，我无法创建PDF 以及如何生成PDF如何以 3X4格式显示？< / p>

OI已从http://jsfiddle.net/5ud8jkvf/11511/获得此代码的引用，此处PDF正确生成，我缺少什么？

我曾使用iTextSharp并使用过它。以下是我的以下代码

using iTextSharp.text;
using iTextSharp.text.pdf;
string shippingaddress = "My name is khan <br/>";
shippingaddress += "And I am not a terrorist<br/>";
        using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())
        {            
            //Below code defines the PDF generate Size
            Rectangle newRect = new Rectangle(0, 0, 240, Convert.ToSingle(138.6));
            Document document = new Document(newRect,10f,10f,10f,10f);
            Document.Compress = true;
            PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
            document.Open();
            Font boldFont = new Font(Font.FontFamily.HELVETICA, 12,Font.BOLD);
            Paragraph para = new Paragraph("Header", boldFont);
            document.Add(para);
            string text = shippingaddress.Replace("<br/>", "\n");
            Paragraph paragraph = new Paragraph();
            paragraph.SpacingBefore = 2;
            paragraph.SpacingAfter = 2;
            paragraph.Leading = 12;
            paragraph.Alignment = Element.ALIGN_LEFT;
            paragraph.Font = FontFactory.GetFont(FontFactory.HELVETICA, 12f,BaseColor.BLACK);
            paragraph.Add(text);
            document.Add(paragraph);
            document.Close();
            byte[] bytes = memoryStream.ToArray();
            memoryStream.Close();
            Response.Clear();
            Response.ContentType = "application/pdf";
            string pdfName = "Movie Name";
            Response.AddHeader("Content-Disposition", "inline; filename=" + pdfName + ".pdf");    
            Response.ContentType = "application/pdf";
            Response.Buffer = true;   
            Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
            Response.BinaryWrite(bytes);
            Response.End();
            Response.Close();    
        }

通过此代码，我能够使用3X4格式创建PDF。 Mat这个答案将是完整的帮助
