Why [removed] = launchFullscreen(document.documentElement); not work?

Question

I use launchFullscreen() function for get page full screen. It\'s work perfect with button onClick.But It doesn\'t work with window.onload

Answer 1

I work around the "must be user action" by binding it to a click event on the HTML element.

$('html').click( function() {
  if(!document.fullscreenElement){
    $('html')[0].requestFullscreen();
  }
});

You just need to remember to touch something once it is loaded. Even if you forgot, the first click will put the page to full screen.

p.s.: Yes, you can easily do this without using jQuery by using proper getElement... functions.
