I run a phpBB board, where I'd like to incorporate pdf.js for pdf presentation (so I can include it in a lightbox; but, I digress). Attachments in phpBB are retrieved using a id, invoking file.php.
Here's a webpage where I present three thumbnails for a pdf: http://59plymouth.net/lightbox/pdfjs2.html
If you click on the first thumbnail, it presents a pdf using pdf.js, but without invoking file.php.
If you click on the second thumbnail, it presents a pdf by invoking file.php, but using the native pdf app for presentation (i.e., w/o pdf.js).
If you click on the third thumbnail, it attempts to present the pdf with a combination of file.php and pdf.js: ...href="./pdfjs/web/viewer.html?file=./download/file.php?id=16187
But of course, the second "?" that invokes file.php is treated literally as data, and not as a query. I've surmised enough to know that I have to use AJAX to accomplish what I want to do, but I don't know how to do it. Can someone point me in the right direction?
