Forms advice for JQM beginner please?

REPOSTING in the right forum:
Hi,

I have built a simple form with a few data fields but I now want to:
  1. intercept the Submit button to run some JavaScript to write the values to LocalStorage variables instead of posting to a server.
  2. Clear the fields and ready the form for another data entry.
Can you advise the right techniques for doing this with JQueryMobile?

Thanks
