Simple wrapper for cross-browser usage of the JavaScript Fullscreen API, which lets you bring the page or any element into fullscreen. Smoothens out the browser implementation differences, so you don't have to.
Only 0.7 kB gzipped.

$ npm install --save screenfull
Also available on cdnjs.
if (screenfull.enabled) {
screenfull.request();
}document.fullscreenEnabled = document.fullscreenEnabled || document.mozFullScreenEnabled || document.documentElement.webkitRequestFullScreen;
function requestFullscreen(element) {
if (element.requestFullscreen) {
element.requestFullscreen();
} else if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
}
}
if (document.fullscreenEnabled) {
requestFullscreen(document.documentElement);
}
// Actually it's more if you want it to work in Safari, but let's not go there...Safari doesn't support use of the keyboard in fullscreen.
document.getElementById('button').addEventListener('click', function () {
if (screenfull.enabled) {
screenfull.request();
} else {
// Ignore or do something else
}
});var elem = document.getElementById('target');
document.getElementById('button').addEventListener('click', function () {
if (screenfull.enabled) {
screenfull.request(elem);
}
});var target = $('#target')[0]; // Get DOM element from jQuery collection
$('#button').click(function () {
if (screenfull.enabled) {
screenfull.request(target);
}
});$('img').click(function () {
if (screenfull.enabled) {
// We can use `this` since we want the clicked element
screenfull.toggle(this);
}
});if (screenfull.enabled) {
document.addEventListener(screenfull.raw.fullscreenchange, function () {
console.log('Am I fullscreen? ' + (screenfull.isFullscreen ? 'Yes' : 'No'));
});
}if (screenfull.enabled) {
document.addEventListener(screenfull.raw.fullscreenerror, function (event) {
console.error('Failed to enable fullscreen', event);
});

You can use the Angular.js binding to do something like:
<div ngsf-fullscreen>
<p>This is a fullscreen element</p>
<button ngsf-toggle-fullscreen>Toggle fullscreen</button>
</div>Make an element fullscreen.
Accepts a DOM element. Default is <html>. If called with another element than the currently active, it will switch to that if it's a decendant.
If your page is inside an <iframe> you will need to add a allowfullscreen attribute (+ webkitallowfullscreen and mozallowfullscreen).
Keep in mind that the browser will only enter fullscreen when initiated by user events like click, touch, key.
Brings you out of fullscreen.
Requests fullscreen if not active, otherwise exits.
Returns a boolean whether fullscreen is active.
Returns the element currently in fullscreen, otherwise null.
Returns a boolean whether you are allowed to enter fullscreen. If your page is inside an <iframe> you will need to add a allowfullscreen attribute (+ webkitallowfullscreen and mozallowfullscreen).
Exposes the raw properties (prefixed if needed) used internally: requestFullscreen, exitFullscreen, fullscreenElement, fullscreenEnabled, fullscreenchange, fullscreenerror
$(document).on(screenfull.raw.fullscreenchange, function () {
console.log('Fullscreen change');
});That's not supported by browsers for security reasons. There is, however, a dirty workaround. Create a seamless iframe that fills the screen and navigate to the page in that instead.
$('#new-page-btn').click(function () {
var iframe = document.createElement('iframe')
iframe.setAttribute('id', 'external-iframe');
iframe.setAttribute('src', 'http://new-page-website.com');
iframe.setAttribute('frameborder', 'no');
iframe.style.position = 'absolute';
iframe.style.top = '0';
iframe.style.right = '0';
iframe.style.bottom = '0';
iframe.style.left = '0';
iframe.style.width = '100%';
iframe.style.height = '100%';
$(document.body).prepend(iframe);
document.body.style.overflow = 'hidden';
