html to pdf javascript

1There is one really good pdf tutorial for javascript that I like.
2Here's the link: https://goalkicker.com/JavaScriptBook

1var doc = new jsPDF();          
2var elementHandler = {
3  '#ignorePDF': function (element, renderer) {
4    return true;
5  }
6};
7var source = window.document.getElementsByTagName("body")[0];
8doc.fromHTML(
9    source,
10    15,
11    15,
12    {
13      'width': 180,'elementHandlers': elementHandler
14    });
15
16doc.output("dataurlnewwindow");
