Re: CFDOCUMENT SRC= and Dynamic HTML
I found a GPLv3 HTML-PDF converter with JS support: http://code.google.com/p/wkhtmltopdf/ Only done a few tests so far, but it looks interesting! ~| Want to reach the ColdFusion community with something they want?

Re: CFDOCUMENT SRC= and Dynamic HTML
Because of formatting bugs with cfdocument, we've had to switch to software called WebGrabber - unlike all the other HTML-PDF generation software I've tried, WebGrabber works in an interesting way: it renders the HTML page and prints it to PDF - so you get what the browser/engine saw. (And with the engine used being WebKit, you get decent CSS support too.) I've just done a quick test with WebGrabber 2009, and it *will* execute JavaScript. (I did a simple For loop, and the resulting PDF contained the 0123456789 output). Unfortunately, it is fairly expensive and Windows-only, but you can try the evaluation version and see if it will work for you. http://www.activepdf.com/products/serverproducts/webgrabber/ ~| Want to reach the ColdFusion community with something they want?

RE: CFDOCUMENT SRC= and Dynamic HTML
Brook,
I don't think that DHTML will render correctly for cfdocument no matter what
you do.

Subject: CFDOCUMENT SRC= and Dynamic HTML
Is there any way to capture a rendered page that uses DHTML? I have a simple
test case where I use some JS to do a document.write('test') to the page and
then use CFDOCUMENT to grab the page via the src attribute. But none of the
dynamic content is ever rendered. Has any one had any success with this?
The only workaround I can think of, and its convoluted and I am not even
sure it would work:
1. Create a Unique ID server side and write a database entry for the
content to fetch
2. Call cfdocument or cfhttp to fetch the page, passing the uniqueID.
3. On the page, include an ajax call back to send back to the server
the documents innerHTML (which should be the dynamic output) along with the
uniqueID
4. The server (polls?) gets the new HTML from the database and uses it
with CFDOCUMENT to create the page.
This is a bit crazy right? There has got to be a better way. And oh yeah,
The output is generated through a lot of JS, so I can't easily reproduce it
on the server and avoid these steps. But, I wish there was some other way..

RE: CFDOCUMENT SRC= and Dynamic HTML
I think you're out of luck. If your pages require a client that parses
and executes JavaScript in able to display all the content, cfhttp and
cfdocument won't do that. I've never been able to find a way to easily
execute JavaScript and collect the rendered HTML on the server.
