I want when my webpage is loading it will be auto fullscreen without clicking on the body.You can take a look at my website that I want to make a change: TV. When you click it anywhere, it will be fullscreen. But I want to make it automatically fullscreen without click anything. I was wondering if I could use auto click to change onClick on the body? Because using onload nothing happened. Can you help me?
I only use <body onclick="toggleFullScreen()"> in my html document.
And this is the javascript of toggleFullScreen:
function errorHandler() {
   alert('mozfullscreenerror');
}
document.documentElement.addEventListener('mozfullscreenerror', errorHandler, false);
// toggle full screen
function toggleFullScreen() {
  if (!document.fullscreenElement &&    // alternative standard method
      !document.mozFullScreenElement && !document.webkitFullscreenElement) {  // current working methods
    if (document.documentElement.requestFullscreen) {
      document.documentElement.requestFullscreen();
    } else if (document.documentElement.mozRequestFullScreen) {
      document.documentElement.mozRequestFullScreen();
    } else if (document.documentElement.webkitRequestFullscreen) {
      document.documentElement.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);
    }
  } else {
    if (document.cancelFullScreen) {
      document.cancelFullScreen();
    } else if (document.mozCancelFullScreen) {
      document.mozCancelFullScreen();
    } else if (document.webkitCancelFullScreen) {
      document.webkitCancelFullScreen();
    }
  }
}
