Which makes the linked file inaccessible to browsers without script
support, that don't understand what to do with a PDF file, or that
over-zealously block popups.
Use a link for links, that's what they're for. Tell users that the
file is a PDF, they can then decide for themselves what to do with it
or rely on their browser's settings to decide for them.
If the OP *really* wants to use a popup, then use:
<a href="doc.pdf" onclick="return openPopup(this.href);">...</a>
Where openPopup() returns true or false depeding on the success of the
function. How to write a openPopup() is explained reasonably well
