Script to submit form to network location, with individual filename.

Hi all,

I'm entirely new to the concept of using Javascript to submit forms, but I'm led to believe this is the path I must take.

I have a form with a simple submit button. On hitting that submit button, I'd like it to save to a specific network folder, ie \\server\share\save, and name the file with the contents of the 'Name' field, and a unique identifier (preferably, the current date and time).

Writing it out like that seems absurdly simple, but I can't figure it out for the life of me..

Any help?
