var specialElementHandlers = {
 '#editor': function (element, renderer) {
  return true;
 }
};
$('#cmd').click(function () {
 doc.fromHTML($('#content').html(), 15, 15, {
  'elementHandlers': specialElementHandlers
 });
 doc.save('sample-file.pdf');
});

<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/jspdf/0.9.0rc1/jspdf.min.js"></script>
<div id="content">
