Based on my Google and stackoverflow search I'm guessing no, but it can't hurt to ask.

The goal is: store some blank forms on my server. Then present these to the user, who edits the form in the browser with Javascript and submits the form back to the server.

The client wants to reuse parts of an old system (the forms) in which users would download an editable PDF, edit it, and email it back to a secretary. Our users aren't very computer savvy and many don't realize they need to email the forms back, assuming instead the forms somehow get submitted when they save their local changes (or something).

I haven't seen the forms yet, so I cannot assess the viability of an alternative.
