At work today, I encountered a need for full-screen display of a web page, so I checked Baidu and found a jQuery plugin for full-screen display of web pages: jquery FullScreen Plugin. It enables full-screen display of web pages for a variety of different browsers, including FF 10, Chrome, and Safari, and is used to provide users with a more readable version of the web page that can be scaled <canvas>and <video>elemented.
jQuery Fullscreen Plugin
Description
This jQuery plugin provides a simple to use mechanism to control the new fullscreen mode of modern browsers. Currently only newer Webkit-based browsers (Like Chrome and Safari), Firefox and IE11+ provide this new fullscreen feature.
Usage
Entering Fullscreen mode
You can either switch the whole page or a single HTML element to fullscreen mode:
$(document).fullScreen(true);
$("#myVideo").fullScreen(true);
This only works when the code was triggered by a user interaction (For example a onclick event on a button). Browsers don't allow entering fullscreen mode without user interaction.
Exiting Fullscreen mode
Fullscreen mode is always exited via the document but this plugin allows it also via any HTML element. The owner document of the selected HTML element is used then:
$(document).fullScreen(false);
$("#myVideo").fullScreen(false);
Querying Fullscreen mode
Simply pass no argument to the fullScreen method to query the current state. The method returns the current fullscreen element (or true if browser doesn't support this) when fullscreen mode is active, false if not active or null when the browser does not support fullscreen mode at all. So you can use this method also to display a fullscreen button only when the browser supports fullscreen mode:
$("#fullscreenButton").toggle($(document).fullScreen() != null))
Toggling Fullscreen mode
The plugin provides another method for simple fullscreen mode toggling:
$(document).toggleFullScreen();
Notifications
The plugin triggers a fullscreenchange event on the document when the fullscreen mode has been changed. If the browser rejected a fullscreen state change then the plugin triggers a fullscreenerror event on the document. Example:
$(document).bind("fullscreenchange", function() {
console.log("Fullscreen " + ($(document).fullScreen() ? " on" : "off"));
});
$(document).bind("fullscreenerror", function() {
alert("Browser rejected fullscreen change");
});
Fullscreen iframe
Entering fullscreen mode from within an iframe is not allowed by default but it can be enabled with a few attributes on the iframe:
<iframe src="iframe.html" webkitAllowFullScreen mozAllowFullScreen allowFullScreen>
</iframe>
Known issues
In IE 11 an empty page is displayed when entering fullscreen from within an iframe. No idea why. Any help is welcome.
In Safari (At least in Safari 7) no keyboard input is allowed in fullscreen mode.
