Setup

class is not required. They are used here to select elements. You may use some other method for elements selection.

data-src is required, and contains URL of your content.

data-padding-bottom is optional, and can be used to change default 16/9 Aspect Ratio to the one of yours with the formula: a percentage value of height/width*100.

For instance, HD would be: 9 / 16 * 100 + "%"

So, for YouTube or Vimeo, data-padding-bottom="56.25%" would be enough.

For SoundCloud embedded player via iframe, use: data-padding-bottom="166px"

YouTube

<a href="javascript:void(0);"
class="iframe-lightbox-link"
data-src="https://www.youtube.com/embed/KK9bwTlAvgo?autoplay=0"
data-padding-bottom="56.25%">YouTube</a>

Vimeo

<a href="javascript:void(0);"
class="iframe-lightbox-link"
data-src="https://player.vimeo.com/video/28629415?autoplay=false"
data-padding-bottom="56.25%">Vimeo</a>

SoundCloud

<a href="javascript:void(0);"
class="iframe-lightbox-link"
data-src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/317031598&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true"
data-padding-bottom="166px">SoundCloud</a>

Initialize

[].forEach.call(document.getElementsByClassName("iframe-lightbox-link"), function(el) {
	el.lightbox = new IframeLightbox(el);
});

Tips

SPA / PWA developers can use CSS flag classes when adding event listeners, e.g.:

[].forEach.call(document.getElementsByClassName("iframe-lightbox-link"), function(el) {
	if (!el.classList.contains("is-binded")) {
		el.lightbox = new IframeLightbox(el);
		el.classList.add("is-binded");
	}
});

That way you avoid multiple assignments to a single element.

Examples of event handling

[].forEach.call(document.getElementsByClassName("iframe-lightbox-link"), function(el) {
   el.lightbox = new IframeLightbox(el, {
	   onLoaded: function(iframe) {
		   console.log("hola", iframe);
	   },
	   onCreated: function(instance) {
		   console.log("margo", instance)
	   },
	   onOpened: function(instance) {
		   console.log("blah", instance)
	   }
   });
});
