Answer 1

From my experience of dompdf(very famous pdf library),those library don't support JS interpreting(because the php don't have the power to interpret the javascript),here are two workaound I think you can try.

1.Server side rendering html,move your dom manipulation to php in order to create the dom element.(Recommended)

2.Use php and phantomJS.The php call phantomJS to capture the screen of html and saved the screenshot to pdf.

Answer 2

PhantomJS works nicely, take a look at this package: https://github.com/jonnnnyw/php-phantomjs

Full documentation here: http://jonnnnyw.github.io/php-phantomjs/

Example:

<?php

use JonnyW\PhantomJs\Client;

$client = Client::getInstance();

$request  = $client->getMessageFactory()->createCaptureRequest('http://google.com');
$response = $client->getMessageFactory()->createResponse();

$file = '/path/to/save/your/screen/capture/file.jpg';

$request->setCaptureFile($file);

$client->send($request, $response);
