How do I get JS to refresh page everytime a person arrives at a page?

I have this script:
<script>
function RefreshWindow() {
window.history.go(0)
}
</script>

The problem is that it doesn't always give me the latest version of my webpage. What am I doing wrong? Would deleting the window.history.go(0) part fix this or make it worse?
Thanks!:D Newbie here.

This page describes exactly what you need to do.

Thanks! The button code does work.

The other script refreshes the page through out the time the player is there and will not work with a memory game. There was no way to change it to only refresh one time only that I could find. It also refused to load the memory game.
