Unable to convert HTML to PDF using jsPDF

I'm able to download a PDF using jsPDF but the downloaded PDF is plain text excluding the styles applied in the website.
I am unable to get the styles or formatting in the website to the downloadable PDF.
Here's the jsPDF code I use:
<button type="button" onclick="convert()" class="pda-button"><i class="save-icon sprite"></i> Save</button>
<div id="content">
//content goes
</div>
<div id="elementH"></div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://demos.codexworld.com/includes/js/bootstrap.js"></script>
<script src="http://demos.codexworld.com/3rd-party/jsPDF/dist/jspdf.min.js"></script>
<script>
function convert() {
var doc = new jsPDF();
var elementHTML = $('#content').html();
var specialElementHandlers = {
'#elementH': function (element, renderer) {
return true;
}
};
doc.fromHTML(elementHTML, 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
// Save the PDF
doc.save('sample-document.pdf');
}
</script>
Here's the link to website I integrated the above code and want to convert to PDF:
Website's link
As I click on save button on the top left of the site to download PDF, the PDF is generated and downloaded but as an plain text PDF with no styles.
And Please do not Down-Vote the post without explaining the reason for doing so..

You need to give a callback function to the method doc.fromHTML
doc.fromHTML(elementHTML, 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
}, function cb() {} );
cb() will tell you that the pdf is ready.

Create PDF file from PHP

I am trying to create an PDF file from a PHP page with jsPDF but it is not working and I dont know whats wrong.
Can someone help me?
First I have a Iframe. The page I want to convert is displayed in the Iframe:
Iframe:
<?php
<iframe id="frame" name="frame" width="100%" height="1160px" frameborder="0" src="./page.php?id=' . $_GET['id'] . '"></iframe>
<button id="cmd">Button</button>
?>
When I hit Button the following script should convert the page to PDF
Script
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>
<script type="text/javascript">
var doc = new jsPDF();
var specialElementHandlers = {
'#editor': function(element, renderer){
return true;
}
};
$('#cmd').click(function () {
doc.fromHTML($('frame').get(0), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
</script>
But when I hit Button. Nothing is happening. Does someone know whats wrong?

You must be get html of iframe, so use contents() function and then get documentElement of iframe:
<iframe id="frame" name="frame" width="100%" height="1160px" frameborder="0" src="http://localhost/"></iframe>
<button id="cmd">Button</button>
<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>
<script type="text/javascript">
var doc = new jsPDF();
var specialElementHandlers = {
'#editor': function(element, renderer){
return true;
}
};
$('#cmd').click(function () {
doc.fromHTML($('#frame').contents().find('html').html(), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
</script>
Note: If your iframe source page or part of it protected with x-frame-options header, you cannot access to html of it.

<button onclick="cmd()">Button</button>
Change this to
<button id="cmd">Button</button>
You are calling the click event in JS on the id. Or change the onclick event to a function with the name cmd.

Apparently, jsPDF has limitations and/or bugs. It has problems with complex tables (especially with colspans). It throws javascript errors which stops the renderer which is why you're getting blank pdfs.

A fork has been posted here: https://github.com/jutunen/jsPDF-table_2 but I'm not sure if it addresses other limitations of jsPDF.

How to add header in pdf generated from HTML

I am working on codeigniter. I want to add save to pdf functionality to one of the div. I am using html2canvas to print it. My problem is I want to add a logo & some other information at the header of the pdf, which is not visible on the webpage. I dont know how to do this. Below is my code.
<script type='text/javascript' src="<?php echo site_url('assets/js/html2canvas.js'); ?>"></script>
<script type='text/javascript' src="<?php echo site_url('assets/js/jspdf.debug.js'); ?>"></script>

Pls help.

Before calling to addHTML, you can add images or text to your jsPDF object:
var pdf = new jsPDF('p','pt','a4');
var imgData = 'data:image/jpeg;base64,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';

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
Run Code
<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>

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.

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);
}
};

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>

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.

capture div into image using html2canvas

I'm trying to capture a div into an image using html2canvas
I have read some similar question here like
How to upload a screenshot using html2canvas?
create screenshot of web page using html2canvas (unable to initialize properly)
I have tried the code
canvasRecord = $('#div').html2canvas();
dataURL = canvasRecord.toDataURL("image/png");
and the canvasRecord will be undefined after .html2canvas() called
and also this
$('#div').html2canvas({
onrendered: function (canvas) {
var img = canvas.toDataURL()
window.open(img);
}
});
browser gives some (48 to be exact) similar errors like:
GET http://html2canvas.appspot.com/?url=https%3A%2F%2Fmts1.googleapis.com%2Fvt%…%26z%3D12%26s%3DGalileo%26style%3Dapi%257Csmartmaps&callback=html2canvas_1 404 (Not Found)
BTW, I'm using v0.34 and I have added the reference file html2canvas.min.js and jquery.plugin.html2canvas.js
How can I convert the div into canvas in order to capture the image.
EDIT on 26/Mar/2013
I found Joel's example works.
But unfortunately when Google map embedded in my app, there will be errors.
<html>

<script language="javascript">

var img = canvas.toDataURL("image/png")
window.open(img);
}
});
});
});
</script>
</head>
<body>
<div id="testdiv">
</div>
<div id="map_canvas"></div>
<input type="button" value="Save" id="load"/>
</body>
</html>

I ran into the same type of error you described, but mine was due to the dom not being completely ready to go. I tested with both jQuery pulling the div and also getElementById just to make sure there wasn't something strange with the jQuery selector. Below is an example that works in Chrome:
<html>
<head>
<style type="text/css">
div {
height: 50px;
width: 50px;
background-color: #2C7CC3;
}
</style>
<script type="text/javascript" src="html2canvas.js"></script>
<script type="text/javascript" src="jquery-1.9.1.js"></script>
<script language="javascript">
$(document).ready(function() {
//var testdiv = document.getElementById("testdiv");
html2canvas($("#testdiv"), {
onrendered: function(canvas) {
// canvas is the final rendered <canvas> element
var myImage = canvas.toDataURL("image/png");
window.open(myImage);
}
});
});
</script>
</head>
<body>
<div id="testdiv">
</div>
</body>
</html>

If you just want to have screenshot of a div, you can do it like this
html2canvas($('#div'), {
onrendered: function(canvas) {
var img = canvas.toDataURL()
window.open(img);
}
});

you can try this code to capture a div When the div is very wide or offset relative to the screen
var div = $("#div")[0];
var rect = div.getBoundingClientRect();
var canvas = document.createElement("canvas");
canvas.width = rect.width;
canvas.height = rect.height;
var ctx = canvas.getContext("2d");
ctx.translate(-rect.left,-rect.top);
html2canvas(div, {
canvas:canvas,
height:rect.height,
width:rect.width,
onrendered: function(canvas) {
var image = canvas.toDataURL("image/png");
var pHtml = "<img src="+image+" />";
$("#parent").append(pHtml);
}
});

This question is quite old, but if anyone looking for a clear solution to implement then here it is. This is using Pure JS with html2canvas and FileSaver
I have tested and it works fine.
Capture everything inside a div.
Step 1
Include the scripts in your footer. jQuery is not needed, These two are fine. If you already have these two in your file, watch out for the correct version. I know it's a little thing, but it is important.
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/2.0.0/FileSaver.min.js"></script>
Step 2
Basic div. The style attribute is optional. I am using it here to make it look presentable.
<div id="savethegirl" style="background-color:coral;color:white;padding:10px;width:200px;">
I am a Pretty girl 👩
</div>
<button onclick="myfunc()">Save the girl</button>
It should look like this
Step 3
Include this script
function myfunc(){
// if you are using a different 'id' in the div, make sure you replace it here.
var element = document.getElementById("savethegirl");
html2canvas(element).then(function(canvas) {
canvas.toBlob(function(blob) {
window.saveAs(blob, "Heres the Girl.png");
});
});
};
Step 4
Click the button and it should save the file.

This is from Carlos Delgado's article (https://ourcodeworld.com/articles/read/415/how-to-create-a-screenshot-of-your-website-with-javascript-using-html2canvas). I simplified it
If this answer is useful.
Hit that up arrow 🠉 It will help others to find it.

I don't know if the answer will be late, but I have used this form.
JS:
function getPDF() {
html2canvas(document.getElementById("toPDF"),{
onrendered:function(canvas){
var img=canvas.toDataURL("image/png");
var doc = new jsPDF('l', 'cm');
doc.addImage(img,'PNG',2,2);
doc.save('reporte.pdf');
}
});
}
HTML:
<div id="toPDF">
#your content...
</div>
<button id="getPDF" type="button" class="btn btn-info" onclick="getPDF()">
Download PDF
</button>

You can get the screenshot of a division and save it easily just using the below snippet. Here I'm used the entire body, you can choose the specific image/div elements just by putting the id/class names.
html2canvas(document.getElementsByClassName("image-div")[0], {
useCORS: true,
}).then(function (canvas) {
var imageURL = canvas.toDataURL("image/png");
let a = document.createElement("a");
a.href = imageURL;
a.download = imageURL;
a.click();
});

It can be easily done using html2canvas, try out the following,
try adding the div inside a html modal and call the model id using a jquery function. In the function you can specify the size (height, width) of the image to be displayed. Using modal is an easy way to capture a html div into an image in a button onclick.
for example have a look at the code sample,
`
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<div class="modal-body">
<p>Some text in the modal.</p>
`
paste the div, which you want to be displayed, inside the model. Hope it will help.

window.open didn't work for me... just a blank page rendered... but I was able to make the png appear on the page by replacing the src attribute of a pre-existing img element created as the target.
$("#btn_screenshot").click(function(){
element_to_png("container", "testhtmltocanvasimg");
});
function element_to_png(srcElementID, targetIMGid){
console.log("element_to_png called for element id " + srcElementID);
html2canvas($("#"+srcElementID)[0]).then( function (canvas) {
var myImage = canvas.toDataURL("image/png");
$("#"+targetIMGid).attr("src", myImage);
console.log("html2canvas completed. png rendered to " + targetIMGid);
});
}
<div id="testhtmltocanvasdiv" class="mt-3">
<img src="" id="testhtmltocanvasimg">
</div>
I can then right-click on the rendered png and "save as". May be just as easy to use the "snipping tool" to capture the element, but html2canvas is an certainly an interesting bit of code!

You should try this (test, works at least in Firefox):
html2canvas(document.body,{
onrendered:function(canvas){
document.body.appendChild(canvas);
}
});
Im running these lines of code to get the full browser screen (only the visible screen, not the hole site):
var w=window, d=document, e=d.documentElement, g=d.getElementsByTagName('body')[0];
var y=w.innerHeight||e.clientHeight||g.clientHeight;
html2canvas(document.body,{
height:y,
onrendered:function(canvas){
var img = canvas.toDataURL();
}
});
