async-youtube-video

Simple async youtube video loading

Attach a YouTube video to an element asynchronously.

Usage

npm install --save-dev async-youtube-video

Include the script on your page

Insert an element with class youtube-iframe-video into your DOM

NB This element will be replaced with the iframe, so ensure you have a wrapping element in your DOM so you can control it.

<div class="video-container">
  <div class="youtube-iframe-video"></div>
</div>

Then initialise

window.onload = function() {
  asyncYoutubeVideo.init({
    targetClass: 'youtube-iframe-video',
    videoId: 'Srmdij0CU1U',
    controls: 1,
    autoplay: 1,
    disablekb: 1,
    fs: 0,
    modestbranding: 1,
    playsinline: 1,
    showinfo: 0,
    origin: 'example.com',
    additionalClasses: 'test-video some-class',
    rel: 0,
    mute: 1,
    loop: 1
  });
}

Required options are videoId, origin and targetClass.

targetClass must match the class of the replacement element in the DOM

Will render

<iframe id="async-youtube-video" src="//www.youtube.com/embed/Srmdij0CU1U?enablejsapi=1&amp;controls=1&amp;autoplay=1&amp;disablekb=1&amp;fs=1&amp;rel=0&amp;modestbranding=1&amp;playsinline=1&amp;showinfo=1&amp;loop=1&amp;origin=http://example.com" frameborder="0" type="text/html" class="test-video some-class async-youtube-video"></iframe>

The options map to YouTube API names for ease of reference.

The names of the variables are somewhat confusing though, so here is a brief rundown.
