Lightest Tweening Engine for jQuery

Why jQueryTween?

  • A super light & simple jQuery plugin that works as a controller for tween.js (javascript animation engine), and for jQuery users, makes work alot easier. Imagine writing init(), animate() and update() over and over again?
  • Supports most popular transitions such as transform, opacity, color and backgroundPosition for up to 60 frames per second.
  • Can also do smooth scrollTo
  • It's about 8k minified and plus 6k of tween.js, you can do a ton of cool things without the need to use expensive or complicated animation engines.
  • This one is simple, light and I dare to say it's much more performance driven when it comes to simple tweens.
  • Keep in mind that tween.js is not included into the jQueryTween plugin, except for the AIO package. See demo for details.



Get to know some features

  • works with jQuery, yes I know it's cool for n00bs and scary for advanced devs
  • developer friendly and heavily documented
  • commercial use friendly license
  • can use all tween.js easing functions, can do delays and repeats
  • supports callback functions to be used for onUpdate or onComplete events
  • performance tweaks, when only a few tween properties are used, the others don't update
  • for most properties you don't need to set an initial value, it gets it's current properties values, except transform (translate,rotate,scale) and position (top,right,bottom,left)
  • tween control: play/pause/stop
  • tween scrollTo window or target
  • tween text color and background-color
  • tween position: top, bottom, left, right (for absolute/relative positioned objects)
  • tween background-position, but only when using percent values for X and Y
  • tween transform - translate3d
  • tween transform - rotateX, rotateY, rotateZ
  • tween transform - scale
  • tween opacity

Quick Example

//Simple example jQueryTween syntax, very simple indeed
 $('#selector').jQueryTween({ to: { opacity: 0.5, translate: {y: 50} }, duration: 700 });

Please notice that it's best to use a unique ID selector to perform an jQueryTween animation, you don't want all your things to fly around.

Advanced Example

 // Complex example jQueryTween syntax 
	from: {
		opacity: 1,
		translate: {x:0, y:0, z:0},
		rotate: {x:0, y:0, z:0},
		scale: 1
	to: {
		opacity: 0.5, 
		translate: {x: 150, y: 50, z: -100}, 
		rotate: {x: 5, y:15, z:-25},
		scale: 1.5
	repeat: 2, // can be number or 'Infinity'
	duration: 1500,
	easing: TWEEN.Easing.Exponential.InOut, // my favorite
	delay: 500,
}, function() {
	//do some cool stuff when tween finished animating
}, function() {
	//do some cool stuff while tween is running 

ScrollTo Tweens

// Scroll to top of window
$('#button').on('click', function() {
	$('body').jQueryTween({ to: { scroll: 0 } });
// Scroll to element when clicking anchor links
$('a#button').on('click', function(e) {
	var target = $( $.attr(this, 'href') );
	$('#element').jQueryTween({ to: { scroll: $(target).offset().top } });

Tween Control

// stops all the object's tweens
 // pauses all the object's tweens 
// resumes all the object's tweens

TO DO / known issues

  • tween to relative values (such as "+200" or "-150") does not work properly with some properties
  • tweening background position only works for percent values
  • tween chaining is not implemented
  • does not tween text properties, spacing, etc, only what's shown in the examples
  • scroll events are only available for document.body, no other containers available
