Cross platform and legacy browser support for triggering on scroll
- Fire only once at the beginning of a scroll
- No subsequent callbacks fired during a scroll/inertia
- Determines direction of the scroll/touch
- IE (10) / Edge / Firefox / Safari / Chrome / iOS / Android
Use Case
Triggering off of scrolling events across multiple platforms while maintaining cross browser support back through IE 10. This was required in a Hype animation: http://tumult.com/hype/.
Our requirements included:
- No 3rd party libraries
- No ES6+
- No JS transpiling
- Trigger callback on scroll up
- Trigger callback on scroll down
- Track swiping on touch devices and trackpads
- No subsequent function calls during scroll (like the inertia from a trackpad)
How to Use
Copy the contents of index.js into wherever scripts are happy. Update the config object as needed, like adding functions to get called in the onDown and onUp properties. If you're seeing multiple calls when scrolling, try adjusting the timing in the config object.
It utilizes the mousewheel cross browser script found here at MDN: https://developer.mozilla.org/en-US/docs/Web/Events/wheel#Listening_to_this_event_across_browser, and magic.
Pull reqs welcome!
