Is it possible to save HTML page as PDF using JavaScript or jquery?
In Detail:
I generated one HTML Page which contains a table . It has one button 'save as PDF'. If user clicks that button then that HTML page has to convert as PDF file.
Is it possible using JavaScript or jquery?
This might be a late answer but this is the best around: https://github.com/eKoopmans/html2pdf
Pure javascript implementation. Allows you to specify just a single element by ID and convert it.
Yes, Use jspdf To create a pdf file.
You can then turn it into a data URI and inject a download link into the DOM
You will however need to write the HTML to pdf conversion yourself.
Just use printer friendly versions of your page and let the user choose how he wants to print the page.
Edit: Apparently it has minimal support
So the answer is write your own PDF writer or get a existing PDF writer to do it for you (on the server).
Ya its very easy to do with javascript. Hope this code is useful to you.
You'll need the JSpdf library.
<div id="content">
<h3>Hello, this is a H3 tag</h3>
<p>a pararaph</p>
</div>
<div id="editor"></div>
<button id="cmd">Generate PDF</button>
<script>
var doc = new jsPDF();
var specialElementHandlers = {
'#editor': function (element, renderer) {
return true;
}
};
$('#cmd').click(function () {
doc.fromHTML($('#content').html(), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
// This code is collected but useful, click below to jsfiddle link.
</script>
I used jsPDF and dom-to-image library to export HTML to PDF.
I post here as reference to whom concern.
$('#downloadPDF').click(function () {
domtoimage.toPng(document.getElementById('content2'))
.then(function (blob) {
var pdf = new jsPDF('l', 'pt', [$('#content2').width(), $('#content2').height()]);
pdf.addImage(blob, 'PNG', 0, 0, $('#content2').width(), $('#content2').height());
pdf.save("test.pdf");
});
});
You can use Phantomjs. Download here and use the following example to test the html->pdf conversion feature https://github.com/ariya/phantomjs/blob/master/examples/rasterize.js
Example code:
phantomjs.exe examples/rasterize.js http://www.w3.org/Style/CSS/Test/CSS3/Selectors/current/xhtml/index.html sample.pdf
Here is how I would do it, its an idea not bulletproof design, you need to modify it
It is much easier and reliable to convert html to pdf server side. We are using Google Puppeteer. It is well maintained with wrappers for any server side language of your choosing. Puppeteer uses headless Chrome to generate screenshots and/or PDF files. It will save you a LOT of headache especially if you need to generate complex PDF files with tables, images, graphs, multiple pages and so
There is another very obvious way to convert HTML to PDf using JavaScript: use an online API for that. This will work fine if you don't need to do the conversion when the user is offline.
PdfMage is one option that has a nice API and offers free accounts. I'm sure you can find many alternatives (for example, here)
For PdfMage API you'd have something like this:
$.ajax({
url: "https://pdfmage.org/pdf-api/v1/process",
type: "POST",
crossDomain: true,
data: { Html:"<html><body>Hi there!</body></html>" },
dataType: "json",
headers: {
"X-Api-Key": "your-key-here" // not very secure, but a valid option for non-public domains/intranet
},
success: function (response) {
window.location = response.Data.DownloadUrl;
},
error: function (xhr, status) {
alert("error");
}
});
I know this is an old question, but depending on the readers use case an easy way is to call window.print() and tell the user to choose the save as PDF option. In CSS you can use media queries to hide or show content specifically for printing so you can control what is shown on the PDF. For example I use these .no-print and .only-print for this purpose.
.only-print {
display: none
}
@media print {
.no-print {
display: none
}
.only-print {
display: block
}
}
In my use case I hide all the navigation and buttons stuff, I also hide some collapsed blocks and instead show all the uncollapsed blocks.
Yes. For example you can use the solution by https://grabz.it.
It's got a Javascript API which can be used in different ways to grab and manipulate the screenshot. In order to use it in your app you will need to first get an app key and secret and download the free Javascript SDK.
So, let's see a simple example for using it:
//first include the grabzit.min.js library in the web page
<script src="grabzit.min.js"></script>
//include the code below to add the screenshot to the body tag
<script>
//use secret key to sign in. replace the url.
GrabzIt("Sign in to view your Application Key").ConvertURL("http://www.google.com").Create();
</script>
Then simply wait a short while and the image will automatically appear at the bottom of the page, without you needing to reload the page.
That's the simplest one. For more examples with image manipulation, attaching screenshots to elements and etc check the documentation.
$('#cmd2').click(function() {
var options = {
//'width': 800,
};
var pdf = new jsPDF('p', 'pt', 'a4');
pdf.addHTML($("#content2"), -1, 220, options, function() {
pdf.save('admit_card.pdf');
});

Had similar issue, could not use jspdf since my legacy code contained multiple tables with several colspan inside. In Jspdf thead > th's must match tbody > tr > td
I ended up using html2pdf package which worked for me
on your file add the library
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2pdf.js/0.8.1/html2pdf.bundle.min.js" integrity="sha512-vDKWohFHe2vkVWXHp3tKvIxxXg0pJxeid5eo+UjdjME3DBFBn2F8yWOE0XmiFcFbXxrEOR1JriWEno5Ckpn15A==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
Get the content you want to save as pdf
var pdf_content = document.getElementById("pdf_body");
Add option or configuration to your file
var options = {
margin: 1,
filename: 'isolates.pdf',
image: { type: 'jpeg', quality: 0.98 },
html2canvas: { scale: 2 },
jsPDF: { unit: 'in', format: 'letter', orientation: 'portrait' }
};
Save the file
html2pdf(pdf_content, options);
In short: no. The first problem is access to the filesystem, which in most browsers is set to no by default due to security reasons. Modern browsers sometimes support minimalistic storage in the form of a database, or you can ask the user to enable file access.
If you have access to the filesystem then saving as HTML is not that hard (see the file object in the JS documentation) - but PDF is not so easy. PDF is a quite advanced file-format that really is ill suited for Javascript. It requires you to write information in datatypes not directly supported by Javascript, such as words and quads. You also need to pre-define a dictionary lookup system that must be saved to the file. Im sure someone could make it work, but the effort and time involved would be better spent learning C++ or Delphi.
HTML export however should be possible if the user gives you non restricted access
