You can check for fullscreen support by checking the truthy/falsy value of screenfull as done in the example above.
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.
Override this method to get notified about fullscreen changes.
Override this method to get notified about fullscreen errors.
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');
});In lieu of a formal styleguide, take care to maintain the existing coding style. Lint and minify your code using grunt.
Also, please don't edit files in the "dist" subdirectory as they are generated via grunt. You'll find source code in the "src" subdirectory!
