Javascript command to hide Querystring?

Hi,

I’d like to know if there’s a way to hide the querystring when using Javascript code to submit my Form!? Right now, I’m using the “location = querystring” command to send my query, but the entire Querystring is displayed in the browser’s address. Since I’m using Javascript to build my querystring, I can’t send a POST method which hides the querystring.

Are there any other Javascript methods I could use instead of the “location=” that will hide the querystring?

Thanks!
Any ideas!?
