Form Data in a form

Form Data in a form

Hi guys,
At a click of a submit button,  i need to know how possible is it to get the data/contents submitted into a new file. this doesn't involve using server or anything else. just submitting the form, and getting the contents in another file. i have done so many lovely stuff with jquery but i seem to find this difficult. i''m ashame to even share my code sincerely. thanks for your help. regards.
