Hmm. As I see it, the JavaScript is irrelevant here. What you probably want is
to have a CGI script output a HTML page with a form included. And the form
fields should be already filled with default values or values that were stored
earlier, like user preferences. Am I right?

I have attached a quick and dirty CGI script that should show the basics of how
this can be done.

For an example, you can look at the source code of the CGI module, there is a
test function in there that uses most of the modules functionality and is also
useful for debugging.

# Mapping of name of form fields to values
form_fields = { 'Name' : 'Gerhard', 'favlanguage' : 'Python' }

# URL of the CGI-Script, probably to be adjusted
cgi_url = '/cgi-bin/ff.py'

print 'Content-type: text/html\n'

print '<html><body><p>'
printRetrievedData()
printForm( form_fields, cgi_url )
print '</p></body></html>'
