Scroll Test

This module provides a function to test whether the user has scrolled past an element or has scrolled to the bottom of the page.

Getting Started

npm install scroll-test

You only need to import this file into your build:

dist/scroll-test.js

Once its imported, you'll be able to test the scroll like this:

var element = document.querySelector('.js-my-element');
scrollTest(window, element);

or like this, for the document itself:

scrollTest(window);

scrollTest() will return true if the user has scrolled the viewport passed the bottom of the element, or up to the bottom of the page.

Parameter	Purpose
window	Needs window for getting the current height of the viewport
element (optional)	If passed, will compare the height of the viewport vs the bottom of the element. If not passed, will compare the height of the viewport against the height of the page.
