Word wrap in generated PDF (using jsPDF)?

You can just use the optional argument maxWidth from the text function.

doc.text(15, 15, reportTitle, { maxWidth: 40 });

That will split the text once it reaches the maxWidth and start on the next line.

Okay I've solved this. I used the jsPDF function, splitTextToSize(text, maxlen, options). This function returns an array of strings. Fortunately, the jsPDF text() function, which is used to write to the document, accepts both strings and arrays of strings.

var splitTitle = doc.splitTextToSize(reportTitle, 180);
doc.text(15, 20, splitTitle);

Auto-paging and text wrap issue in JSPDF can achieve with following code

 var splitTitle = doc.splitTextToSize($('#textarea').val(), 270);
    var pageHeight = doc.internal.pageSize.height;
    doc.setFontType("normal");
    doc.setFontSize("11");
    var y = 7;
    for (var i = 0; i < splitTitle.length; i++) {                
        if (y > 280) {
            y = 10;
            doc.addPage();
        }
        doc.text(15, y, splitTitle[i]);
        y = y + 7;
    }
    doc.save('my.pdf');
