jquery.youtube-background

v1.0.8

Another 100 liner in a form of a jQuery plugin created to facilitate YouTube embeds as a cover background using YouTube Embed API.

I wrote this code several times over the years and never bothered to make it reusable. Now when I needed it again I could not even find where I wrote it last...

Goodbye careless days... I'm getting old...

DEMO HERE ⤻

Features

• Fade in CSS animation
• Play/Pause button
• Mute/Unmute button
• No CSS required
• No longer jQuery dependant

Usage

Usage is pretty simple, add a data attribute data-youtube containing a full YouTube link or just the YouTube ID.

You can trigger all elements containing the noted attribute with $("[data-youtube]").youtube_background();, or specify your selector, on jQuery document ready event.

Note: From version 1.0.6 jQuery is no longer a dependency, but purely optional. To initialise youtube video backgrounds without jQuery use: new VideoBackgrounds('[data-youtube]');.

P.S. https://www.youtube.com/player_api is injected automatically, only once per script init. I've seen some implementations like Elementor WP plugin that inject it several times, for no reason. Anyway, you're welcome.

Quick Example

	<style>
		/* optional css fade in animation */
		iframe {
			transition: opacity 500ms ease-in-out;
			transition-delay: 250ms;
		}
	</style>

	<!-- target element -->
    <div data-youtube="https://www.youtube.com/watch?v=eEpEeyqGlxA"></div>

    <script type="text/javascript">
        jQuery(document).ready(function() {
            jQuery('[data-youtube]').youtube_background();
        });
    </script>

Development

Development setup uses GULP with Rollup to bundle ES modules into IIFE jquery.youtube-background.js and jquery.youtube-background.min.js

To install the required packages for running GULP, run:

npm install

To run the server on http://localhost:4040, run:

gulp

Code will automatically be packaged into IIFE while you develop.

To generate minified version of the code, run:

gulp build --production

todo

• Autoplay property
• Mute property and button #4
• Add another wrapper so video can fade in when loaded
• Add play-pause, mute-unmute events
• Test the execution order
• Refactor the code to provide foundation for unified solution from multiple providers and sources called video-background
• https://developers.google.com/web/updates/2017/09/autoplay-policy-changes
• Pause and mute on inactivity option
• Play only when in viewport if IntersectionObserver available, also can be toggled as an option
• Perform final tests on BrowserStack and comment the code

THE END.
