Here is the JavaScript code that can make a webpage go fullscreen upon clicking a link:
<a href="javascript:void(0)" onclick="javascript:toggleFullScreen()"></a>
// mozfullscreenerror event handler
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();
}
}
}
// keydown event handler
document.addEventListener('keydown', function(e) {
if (e.keyCode == 13 || e.keyCode == 70) { // F or Enter key
toggleFullScreen();
}
}, false);Is there a way to show scroll overflow only when in fullscreen mode and hide it when the user exits fullscreen either by clicking the same link again or by another method?
