Copy form contents to a file

[Fletcher Blanch]

How can I use JS to copy the contents of a form to a folder/file on the client computer?
The computer is offline so no web server is involved. Thanks.

You can't. There is no file i/o in javascript.

Thanks, Gil. Is there a client-side solution to this problem? I want to be able to access form contents that have been supplied by users who have viewed the page on an offline browser.
Is there a way to save/collect these user inputs on the client computer?
