Usage

Include bc.imagesloaded as a dependency in your project:

bc-imagesloaded

Use this directive directly on an image as an attribute to create an imagesloaded instance for that specific image:

<img
  src="http://lorempixel.com/400/300"
  bc-imagesloaded
  alt=""
/>

:tv: Element usage demo

You can also pass in a selector string, NodeList or array to target multiple child elements:

<div bc-imagesloaded=".test">
  <img
    class="test"
    src="http://lorempixel.com/400/300"
    alt=""
  />
  <img
    class="test"
    src="http://lorempixel.com/400/300"
    alt=""
  />
</div>

bc-background

Set this attribute to true to enable imagesloaded on the background of the current element:

<div
  bc-imagesloaded
  bc-background="true"
  style="background-image: url(http://lorempixel.com/400/300)"
></div>

You can also pass in a selector string to enable imagesloaded on multiple child elements:

<div
  bc-imagesloaded
