Making download link to DOMPDF generated pdf on same page

I'm making a dynamic html page generated with values from a database. The user has the option to "hide" divs and manipulate other elements on the page. I want to send all the HTML on the page to DOMPDF and have it generate a download link for me. 

<a href="dl.php">Download</a>

Where dl.php would have something like this where the html is sent to DOMPDF and generated:

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("myCV.pdf");

However since the user is manipulating the DOM on the page and I want to get rid of stuff like links, I'm using jquery to grab the html

   $('a').wrap('<span style="display:none;"></span>');
   var fullhtml = $("#body").html();
   fullhtml = encodeURIComponent(fullhtml);

annnndd since it's a large page, I can't use GET, have to use POST to send the html. How would I get it so that I can just do a AJAX call with the html to dl.php and just 'include' the page so that it runs? If I return anything from a AJAX call, the pdf file gets converted into text which is a mess.

I'm not sure I understand your question exactly, but as far as I understand, you're taking the HTML of the page, hiding all the links, and then submitting the whole thing inside a POST request to dl.php, right? So dl.php would say something like this:

$html = urldecode($_POST['html']);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
//...

Right?

You could have the user initiate this process by clicking a link, at which point you populate a form with a hidden input with the processed HTML (links hidden, etc.) before the submission takes place, i.e.:

$('a#submit_link').click(function() {
  // wrap links, etc. here
  var html = $("body").html();
  $('#hidden_form_input').val($html);
  $('#hidden_form').submit();
});

Something like this should then present your user with the generated PDF.
