countUp.js

countUp.js is a dependency-free, lightweight JavaScript "class" that can be used to quickly create animations that display numerical data in a more interesting way.

Despite its name, countUp can count in either direction, depending on the startVal and endVal params that you pass.

countUp.js supports all browsers.

Usage:

Params:

• target = id of html element, input, svg text element, or var of previously selected element/input where counting occurs
• startVal = the value you want to begin at
• endVal = the value you want to arrive at
• decimals = number of decimal places in number, default 0
• duration = duration in seconds, default 2
• options = object that determines number formatting and toggles easing - see demo

Decimals, duration, and options can be left out to use the default values.

var numAnim = new countUp("SomeElementYouWantToAnimate", 24.02, 99.99);
numAnim.start();

with optional callback:

numAnim.start(someMethodToCallOnComplete);

// or an anonymous function
numAnim.start(function() {
	// do something
})

Other methods:

Stop an animation in progress:

numAnim.stop();

Resume a stopped animation:

numAnim.resume();

Reset an animation:

numAnim.reset();
