title: Jspdf special element handler for all elements beginning with "#ember"
body: <p>I am using the jspdf library to generate a PDF from an html page with a lot of javascript. The javascript framework I am using is Ember, so there are a lot of id="ember234" tags inserted everywhere, with the digits on the end being generated randomly.  </p>
  
  <p>Jspdf cannot handle these elements, so I'll need to insert them in the elementHandlers hash below.  Is there a way to add any element that starts with the substring "ember" to this hash?  Many thanks for your help</p>
  
  <pre><code>  var doc = new jsPDF();
    doc.fromHTML($('.report-management-interface').html(), 15, 15, {
        'width': 170,
        'elementHandlers': {}
    });
    doc.save('sample-file.pdf');
  </code></pre>
