Fullscreen mode via JavaScript

Hello there,

How can I set pano tour via link to fullscreen mode. I am not JS or any programmer (just html,css) so it makes me a bit confused also I have look at posts on forum and found nothing, actually.

So any advice from you guys would be great ;)

I dunno how to tweak this code to make it happen.
Useful link but I dunno https://krpano.com/docu/actions/#js

Let say: fullscreen.js

function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto');
}

Is this usefull some how?

Thanks lads in advance,

Martin
