scrollback

This simple module allows you to hook up a callback for when the user scrolls the page to a particular Y position, either going up or down.

How to use it

Import as an ES6 Module...

<script type="module">
  import scrollback from './scrollback.mjs'
</script>

...or as a simple script (ES5)

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

Create a request object

const request = {
  callback: callbackReference,
  position: positionInPixelsToTriggerCallback,
  direction: ifTheCallbackIsTriggerGoingUpDownOrBoth, // Optional. Default "down"
  oneShot: isItCallableOnlyOnce // Optional. Default false
}

Attach request with register method

scrollback.register( request )
