## Install
Only 0.7 kB gzipped.
Download the [production version][min] or the [development version][max].
[min]: https://github.com/sindresorhus/screenfull.js/raw/master/dist/screenfull.min.js
[max]: https://github.com/sindresorhus/screenfull.js/raw/master/dist/screenfull.js
```
$ npm install screenfull
```
Also available on [cdnjs](https://cdnjs.com/libraries/screenfull.js).
## Why?
### Screenfull
```js
if (screenfull.isEnabled) {
screenfull.request();
}
```
### Vanilla JavaScript
```js
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);
}
// This is not even entirely comprehensive. There's more.
```
## Support
[Supported browsers](http://caniuse.com/fullscreen)
**Note:** In order to use this package in Internet Explorer, you need a [`Promise` polyfill](https://github.com/stefanpenner/es6-promise).
**Note:** Safari is supported on desktop and iPad, but not on iPhone. This is a limitation in the browser, not in Screenfull.
## Documentation
### Examples
#### Fullscreen the page
```js
document.getElementById('button').addEventListener('click', () => {
if (screenfull.isEnabled) {
screenfull.request();
} else {
// Ignore or do something else
}
});
```
#### Fullscreen an element
```js
const element = document.getElementById('target');
document.getElementById('button').addEventListener('click', () => {
if (screenfull.isEnabled) {
screenfull.request(element);
}
});
```
#### Fullscreen an element with jQuery
```js
const element = $('#target')[0]; // Get DOM element from jQuery collection
$('#button').on('click', () => {
if (screenfull.isEnabled) {
screenfull.request(element);
}
});
```
#### Toggle fullscreen on a image with jQuery
```js
$('img').on('click', event => {
if (screenfull.isEnabled) {
screenfull.toggle(event.target);
}
});
```
#### Detect fullscreen change
```js
if (screenfull.isEnabled) {
screenfull.on('change', () => {
console.log('Am I fullscreen?', screenfull.isFullscreen ? 'Yes' : 'No');
});
}
```
Remove listeners with:
```js
screenfull.off('change', callback);
```
#### Detect fullscreen error
```js
if (screenfull.isEnabled) {
screenfull.on('error', event => {
console.error('Failed to enable fullscreen', event);
});
}
```
See the [demo](https://sindresorhus.com/screenfull.js) for more examples, and view the source.
#### Fullscreen an element with Angular.js
You can use the [Angular.js binding](https://github.com/hrajchert/angular-screenfull) to do something like:
```html
<div ngsf-fullscreen>
<p>This is a fullscreen element</p>
<button ngsf-toggle-fullscreen>Toggle fullscreen</button>
</div>
```
#### Fullscreen the page with Angular 2
```ts
import {Directive, HostListener} from '@angular/core';
import screenfull = require('screenfull');
@Directive({
selector: '[toggleFullscreen]'
})
export class ToggleFullscreenDirective {
@HostListener('click') onClick() {
if (screenfull.isEnabled) {
screenfull.toggle();
}
}
}
```
```html
<button toggleFullscreen>Toggle fullscreen<button>
```
### API
#### .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.
Returns a promise that resolves after the element enters fullscreen.
#### .exit()
Brings you out of fullscreen.
Returns a promise that resolves after the element exits fullscreen.
#### .toggle()
Requests fullscreen if not active, otherwise exits.
Returns a promise that resolves after the element enters/exits fullscreen.
#### .on(event, function)
Events: `'change' | 'error'`
Add a listener for when the browser switches in and out of fullscreen or when there is an error.
#### .off(event, function)
Remove a previously registered event listener.
#### .onchange(function)
Alias for `.on('change', function)`
#### .onerror(function)
Alias for `.on('error', function)`
#### .isFullscreen
Returns a boolean whether fullscreen is active.
#### .element
Returns the element currently in fullscreen, otherwise `null`.
#### .isEnabled
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`
## 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.
```js
$('#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';
});
```
