TypeError: pdf.fromHTML is not a function while converting html to pdf using jspdf

I am trying to convert jsp code to PDF file using jsPDF. But it is giving me the
TypeError: pdf.fromHTML is not a function.
I have downloaded the jspdf zip from https://github.com/MrRio/jsPDF.
My code is :

<head>

<title>Exporting table data to pdf Example</title>


<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.js"></script>
<script src="jsPDF/jspdf.js"></script>
<script src="jsPDF/main.js"></script>



<script type="text/javascript">
$(document).ready(function() {

$("#exportpdf").click(function() {
var pdf = new jsPDF('p', 'pt', 'ledger');
// source can be HTML-formatted string, or a reference
// to an actual DOM element from which the text will be scraped.
source = $('#yourTableIdName')[0];

// we support special element handlers. Register them with jQuery-style
// ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
// There is no support for any other type of selectors
// (class, of compound) at this time.
specialElementHandlers = {
// element with id of "bypass" - jQuery style selector
'#bypassme' : function(element, renderer) {
// true = "handled elsewhere, bypass text extraction"
return true
}
};
margins = {
top : 80,
bottom : 60,
left : 60,
width : 522
};
// all coords and widths are in jsPDF instance's declared units
// 'inches' in this case
pdf.fromHTML(source, // HTML string or DOM elem ref.
margins.left, // x coord
margins.top, { // y coord
'width' : margins.width, // max width of content on PDF
'elementHandlers' : specialElementHandlers
},

function(dispose) {
// dispose: object with X, Y of the last line add to the PDF
// this allow the insertion of new lines after html
pdf.save('fileNameOfGeneretedPdf.pdf');
}, margins);
});

});
</script>

Answer

You're loading in the wrong file.

With Javascript libraries, there are the raw source files, and then there's the compiled files ready for distribution. So whenever you're looking at a library like this, and you want to find the file to include, it's common to check in the dist/ directory. So all you need to include is either jspdf.debug.js or jspdf.min.js

The examples included in the repository are a good way to know how to include and use the library. Check out the basic example here:
