show/hide and reset only once, when doc opens

Hello all. I have a 3 page doc that I'd like to show/hide and reset certain fields only once. Once, at the time of opening the doc. I'm trying to have a fresh page every time I open the doc. Not, when navigating to the next page and then going back to the opening first page. I've searched a bit trying to find an example of javascript that will do the job without any luck. Can someone point me in the right direction to accomplishing this? Thank you for the help.
