videos.js: Efficient embedded video

Embedded video that doesn't cause traffic until clicked.

How to include the script

The stylesheet is best included in the header of the document.

<link rel="stylesheet" href="css/videos.css"/>

This include can be added to the header or placed inline before the script is invoked.

<script src="js/videos.js"></script>

Or use Require.js.

requirejs([
	'js/videos.js'
], function(Videos) {
	...
});

Or import into an MVC framework.

var Videos = require('js/videos.js');

How to start the script

<ul class="videos-list">
	<li class="videos-preview"><a href="//www.youtube.com/watch?v=jg3vSp6t2wU"><img alt="" src="//img.youtube.com/vi/jg3vSp6t2wU/mqdefault.jpg"/></a></li>
	<li class="videos-preview"><a href="//www.youtube.com/watch?v=guwexeBxfFs"><img alt="" src="//img.youtube.com/vi/guwexeBxfFs/mqdefault.jpg"/></a></li>
	<li class="videos-preview"><a href="//www.youtube.com/watch?v=nzE_gzRu_lU"><img alt="" src="//img.youtube.com/vi/nzE_gzRu_lU/mqdefault.jpg"/></a></li>
</ul>

href/src - The URL's contain the video embed codes in the URLs.

var videos = new Videos({
	'elements' : document.querySelectorAll('.videos-list a'),
	'template' : '<iframe src="//www.youtube.com/embed/{id}?autoplay=1" height="400" width="300"></iframe>',
	'separator' : /v=/gi
});

elements : {DOM Elements} - Links to videos for the script to target.

template : {string} - The format of the video embed {id} will be replaced by the embed code.

separator : {regexp} - A string or regular expression indicating where the embed code starts in the video URL.
