jquery-scrollstop
This plugin fires two events on window when scrolling starts and stops:
scrollstart and scrollstop.
Example
The example shows a small box in the upper left that says "SCROLLING" and
colors the body different colors when scrolling:

Usage
scrollstart fires after the first scroll event and won't fire again until
after a scrollstop event is fired.
scrollstop fires after no scroll events have fired for 250 milliseconds.
$(window)
.on("scrollstart", function() {
// Paint the world yellow when scrolling starts.
$(document.body).css({background: "yellow"});
})
.on("scrollstop", function() {
// Paint it all green when scrolling stops.
$(document.body).css({background: "green"});
})
Configuration
latency
latency is the minimum time between the last scroll event and when the
scrollstop event fires. Set $.event.special.scrollstop.latency to the
desired number of milliseconds (default: 250).
// Configure time between final scroll event and
// `scrollstop` event to 650ms (default is 250ms).
$.event.special.scrollstop.latency = 650;
latency per element
Latency can be configured per-element by passing options when the event listener
is bound. If multiple event listeners are bound to the same element, only the
data from the first event listener will set the configuration.
// Configure latency to 650ms for #scrolling-div
$("#scrolling-div").on("scrollstop", {latency: 650}, function() { ... });
jQuery Version Support
The plugin is tested in jQuery 1.2.3+ and jQuery 2.0.3+.
