This plugin provides a technique for detecting if a browser is in fullscreen mode.

Add jQuery and jquery.fullscreen.js to your HTML document. No explicit initialization is required, this plugin handles that automatically. Afterwards, bind a fullscreen event to the window object. Example:

$(window).bind("fullscreen-on", function(e) {
    console.log("we're on fullscreen now");
});

The following events are provided:

• fullscreen-toggle is triggered whenever the fullscreen state changes. The event handling function takes the following form:

    $(window).bind("fullscreen-toggle", function(e, state) {
        ...
    });
  

  where state represents the fullscreen state as a boolean value;

• fullscreen-on is triggered when the browser enters fullscreen;

• fullscreen-off is triggered when the browser exits fullscreen.

• fullscreen-key is triggered when detecting pressing the shortcut key for toggling the browser's fullscreen state (working only on Chrome and Firefox). The event handling function takes the following form:

    $(window).bind("fullscreen-key", function(e, shortcut, longform) {
        ...
    });
  

  where shortcut represents the pressed keys as a string value, and longform represents its longform textual representation;

If you need to check the current fullscreen state, grab the fullscreen-state data property from the window object, as follows:

var isFullScreen = $(window).data('fullscreen-state');

If you need to check the shortcut key and corresponding longform, grab the fullscreen-key data property from the window object, as follows:

var data = $(window).data('fullscreen-keys'); // returns an object in the form of { shortcut: "...", longform: "..." }

The example.html document details examples for all events.

• There is no cross-browser way to programmatically trigger the fullscreen state.
• This has only been tested in Safari (OS X), Google Chrome, Opera, and Firefox. Support for more browsers is coming soon.
