Waypoints is a small jQuery plugin that makes it easy to execute a function whenever you scroll to an element. Waypoints makes a solid base for modern UI patterns that depend on a user’s scroll position on the page. Take a look at a few examples.
Waypoints is dual licensed under the MITand GPL licenses. You can fork the project or report any issues in the GitHub repository.
Waypoints has been tested with jQuery versions 1.4+ in IE6+, FF3+, Safari 4+, and Chrome 6+.
