Class: Fx

Fx.Transitions overrides the base Fx constructor, and adds the possibility to use the transition option as string.

Transition option:

The equation to use for the effect. See Fx.Transitions. It accepts both a function (ex: Fx.Transitions.Sine.easeIn) or a string ('sine:in', 'bounce:out' or 'quad:in:out') that will map to Fx.Transitions.Sine.easeIn / Fx.Transitions.Bounce.easeOut / Fx.Transitions.Quad.easeInOut

Object: Fx.Transitions

A collection of tweening transitions for use with the Fx classes.


$('myElement').set('tween', {transition: Fx.Transitions.Elastic.easeOut});
$('myElement').tween('margin-top', 100);

Class: Fx.Transition

This class is only useful for math geniuses who want to write their own easing equations. Returns an Fx transition function with 'easeIn', 'easeOut', and 'easeInOut' methods.


var myTransition = new Fx.Transition(transition[, params]);


  1. transition - (function) Can be a Fx.Transitions function or a user-provided function which will be extended with easing functions.
  2. params - (mixed, optional) Single value or an array for multiple values to pass as the second parameter for the transition function. A single value will be transformed to an array.


  • (function) A function with easing functions.


// Your own function. Here overshoot is bigger (now 1.3) when base -> 1 and base != 1.
var myTransition = new Fx.Transition(function(pos, x){
    return 1 - Math.pow(Math.abs(Math.log(pos) / Math.log(x && x[0] || Math.E)), pos);
}, 1.3);
var myFx = new Fx.Tween('myElement', {
    property: 'height',
    transition: myTransition.easeOut
}).start(30, 100);
