get values are in the url and therefore accessible to javascript.
try this on for size:

post values are in the http headers making them inaccessible to javascript.

are you trying to keep users from reloading a page that results in a form
post?
i personally don't think there's any way to reliably detect whether a page
has been reloaded or not.
perhaps if you explain what you're actually trying to accomplish you'll get
a more helpful answer.
thanks,
