Fullscreen an element with Angular.js
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>Methods
.request()
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.
.exit()
Brings you out of fullscreen.
.toggle()
Requests fullscreen if not active, otherwise exits.
Properties
.isFullscreen
Returns a boolean whether fullscreen is active.
.element
Returns the element currently in fullscreen, otherwise null.
.enabled
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).
.raw
Exposes the raw properties (prefixed if needed) used internally: requestFullscreen, exitFullscreen, fullscreenElement, fullscreenEnabled, fullscreenchange, fullscreenerror
$(document).on(screenfull.raw.fullscreenchange, () => {
console.log('Fullscreen change');
});FAQ
How can I navigate to a new page when fullscreen?
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(() => {
const 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';
