@brightspace-ui-labs/fullscreen-api

A simple Polymer based Web Component wrapper for the HTML5 full screen API.

Please refer to the component page for more informations.

Available Web Components

• fullscreen-api: The most flexible, comes without UI but with bindable attributes. Ideal when you need to dynamically set the element to display fullscreen (e.g. building and image gallery).
• fullscreen-icon-button: Prepackaged material icon-button. Drop it on your page, tap it and it works.

Both elements share a common API and let you define what to display in full screen mode (via the target attribute) and toggle normal/full screen mode by calling the toggleFullscreen() method.

Note that this method MUST be triggered directly by user interaction (typically in a native onclick or Polymer's on-click handler). If no target is set, the whole page (more specifically document.documentElement) will be displayed full screen.

Attributes

• target : The element to display full screen (document.documentElement by default), or the selector to use to automatically find that element. Note that changing the target while in full screen mode will not have any effect, as toggling between display modes MUST be triggered by user interaction.

• fullscreen : Read-only flag (boolean) indicating if an element is being displayed full screen.

• fullscreenAvailable : Read-only flag (boolean) indicating if full screen mode is available on the browser (Safari on iOS does not support it).

Methods

• toggleFullscreen() : Toggle between full screen and normal display mode. MUST be triggered directly by user interaction (typically in a native 'onclick' or Polymer's 'on-click' handler).

• exitFullscreen() : Exit full screen mode (if toggled).

Examples

• fullscreen-api

<template is="dom-bind">
	<fullscreen-api id="fsapi" fullscreen-available="{{fullscreenAvailable}}"></fullscreen-api>

	<button type="button" onclick="goFullscreen()" hidden$="[[!fullscreenAvailable]]">Display this page in full screen mode</button>

	<div id="errorDiv" hidden$="[[fullscreenAvailable]]">
		Your browser does not support the HTML5 full screen API... :(
	</div>
</template>

<script>
	function goFullscreen() {
	  var fsapi = document.querySelector('#fsapi');
	  fsapi.toggleFullscreen();
	}
</script>

• fullscreen-icon-button

    <fullscreen-icon-button target="#myElementToDisplayFullscreen" title="fullscreen" alt="fullscreen" tabindex="0"></fullscreen-icon-button>

Demo!

When running the demo locally via polymer serve, you need to add a trailing / to the end of the component links in order to get them to render. For example, when directed to http://127.0.0.1:8081/components/fullscreen-api you will need to add a /.
