In my application I need to download pdf by parsing HTML on client side itself. For generating pdf on client side I am using jsPdf. Following is my code.

PdfGenerator.java

public static native String createPDF() /*-{
        $wnd.createPDF(); 
}-*/;

entrypoint.html

 function createPDF(){
         try {
          var doc = new jsPDF();
           doc.text(20, 20, 'This PDF has a title, subject, author, keywords and a crea');
           doc.output('datauri');
           var out = doc.output();
           var url = 'data:application/pdf;base64,' + Base64.encode(out);
           document.location.href = url;
        } catch (e) {
            return e.message;
        }
        return "";
};

I have added all the js in my project and defined script as well. But whenever I call this method then it is giving output "sprintf is not defined.". Please let me know if I am missing out something.

I guess you forget to add the scripts for sprintf.js and base64 js. As jsPdf.js internally uses both of these js.

entrypoint.html

<script type="text/javascript" src="base64.js"></script>
<script type="text/javascript" src="sprintf.js"></script>
<script type="text/javascript" src="jspdf.js"></script>

In the latest builds of jsPDF, you don't need base64 or sprintf, just jspdf.min.js found in the 'dist' folder, includes all the plugins (except downloadify/swfobject).

Just updating an old ticket if someone runs across it when trying to figure out jsPDF due to it's not so good documentation.

You don't need to plicate your code by using window.location. JsPDF has method .save() to handle it.

function createPDF(){
         try {
           var doc = new jsPDF();
           doc.text(20, 20, 'This PDF has a title, subject, author, keywords and a crea');
           doc.save('file_name.pdf');
        } catch (e) {
            return e.message;
        }
        return "";
};

Depending on what browser you are supporting (all browser versions, and IE 10+), you don't even need to include Base64.encode(). Just call btoa() instead.
