How to properly use jsPDF library

I want to convert some of my divs into PDF and I've tried jsPDF library but with no success. It seems I can't understand what I need to import to make the library work. I've been through the examples and I still can't figure it out. I've tried the following:

<script type="text/javascript" src="js/jspdf.min.js"></script>

After jQuery and:

$("#html2pdf").on('click', function(){
	var doc = new jsPDF();
	doc.fromHTML($('body').get(0), 15, 15, {
		'width': 170
	});
	console.log(doc);
});

for testing purposes but I receive:

"Cannot read property '#smdadminbar' of undefined"

where #smdadminbar is the first div from the body.

you can use pdf from html as follows,

Step 1: Add the following script to the header

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

or download locally

Step 2: Add HTML script to execute jsPDF code

Customize this to pass the identifier or just change #content to be the identifier you need.

 <script>
	function demoFromHTML() {
		var pdf = new jsPDF('p', 'pt', 'letter');
		// source can be HTML-formatted string, or a reference
		// to an actual DOM element from which the text will be scraped.
		source = $('#content')[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: 40,
			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('Test.pdf');
		    }, margins
        );
	}
</script>

Step 3: Add your body content

<a href="javascript:demoFromHTML()" class="button">Run Code</a>
<div id="content">
    <h1>  
        We support special element handlers. Register them with jQuery-style.
    </h1>
</div>

Refer to the original tutorial

See a working fiddle

You only need this link jspdf.min.js

It has everything in it.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

This is finally what did it for me (and triggers a disposition):

function onClick() {
  var pdf = new jsPDF('p', 'pt', 'letter');
  pdf.canvas.height = 72 * 11;
  pdf.canvas.width = 72 * 8.5;

  pdf.fromHTML(document.body);

  pdf.save('test.pdf');
};

var element = document.getElementById("clickbind");
element.addEventListener("click", onClick);

<h1>Dsdas</h1>

<a id="clickbind" href="#">Click</a>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.3/jspdf.min.js"></script>

> And for those of the KnockoutJS inclination, a little binding:

ko.bindingHandlers.generatePDF = {
    init: function(element) {

        function onClick() {
            var pdf = new jsPDF('p', 'pt', 'letter');
            pdf.canvas.height = 72 * 11;
            pdf.canvas.width = 72 * 8.5;
            
            pdf.fromHTML(document.body);

            pdf.save('test.pdf');                    
        };

        element.addEventListener("click", onClick);
    }
};

According to the latest version (1.5.3) there is no fromHTML() method anymore. Instead you should utilize jsPDF HTML plugin, see: https://rawgit.com/MrRio/jsPDF/master/docs/module-html.html#~html

You also need to add html2canvas library in order for it to work properly: https://github.com/niklasvh/html2canvas

JS (from API docs):

var doc = new jsPDF();   

doc.html(document.body, {
   callback: function (doc) {
     doc.save();
   }
});

You can provide HTML string instead of reference to the DOM element as well.

Shouldn't you also be using the jspdf.plugin.from_html.js library? Besides the main library (jspdf.js), you must use other libraries for "special operations" (like jspdf.plugin.addimage.js for using images). Check https://github.com/MrRio/jsPDF.

first, you have to create a handler.

var specialElementHandlers = {
	'#editor': function(element, renderer){
		return true;
	}
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
	'width': 170, 
	'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

how about in vuejs how is it applicable?

function onClick() {
  var pdf = new jsPDF('p', 'pt', 'letter');
  pdf.canvas.height = 72 * 11;
  pdf.canvas.width = 72 * 8.5;

  pdf.fromHTML(document.body);

  pdf.save('test.pdf');
};

var element = document.getElementById("clickbind");
element.addEventListener("click", onClick);

<h1>Dsdas</h1>

<a id="clickbind" href="#">Click</a>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.3/jspdf.min.js"></script>
