moofx (3) is a css3-enabled javascript animation library

features

  • uses css3 transitions whenever available, falls back to normal javascript animation otherwise.
  • supports animating between different types of units, such as em to px, px to %, etc.
  • supports hsl colors for color-based properties.
  • supports transform animations in webkit browsers, firefox and ie9+.
  • includes a computedStyle normalizer.
  • framework agnostic, is easily pluggable in your favorite js framework.
  • cross browser.
  • small footprint, 6k gzipped (including dependencies).
  • simple api

API

Every property in moofx can either be provided camelized (backgroundColor) or hyphenated (background-color). Colors can be provided as rbg (rgb(20,30,40)), rbga (rbga(20,30,40,0.5)), hsl (hsl(20,30,40)), hsla (hsla(20,30,40,0.5)) hex (#fa0, #ffaa00), or hexa (#ffaa00ff, #fa0f). Lengths will always be retrieved in pixels, unless they have a value of auto, and you are able to animate from to whatever length unit to whatever length unit.

moofx3 can animate and has full support for the following properties: backgroundColor, color, backgroundSize, fontSize, height, width, marginTop, paddingTop, borderTopWidth, top, borderTopColor, borderTopStyle, marginRight, paddingRight, borderRightWidth, right, borderRightColor, borderRightStyle, marginBottom, paddingBottom, borderBottomWidth, bottom, borderBottomColor, borderBottomStyle, marginLeft, paddingLeft, borderLeftWidth, left, borderLeftColor, borderLeftStyle, borderTopLeftRadius, borderTopRightRadius, borderBottomRightRadius, borderBottomLeftRadius, zIndex, margin, padding, borderRadius, borderWidth, borderColor, borderTop, borderRight, borderBottom, borderLeft, border, opacity, boxShadow, textShadow and transform. Every other css property is handled automatically using getComputedStyle.

moofx

the moofx method takes as first argument either a collection of nodes (such as the return value of document.querySelectorAll) an array of nodes (such as the expected return value of every dom selector library available, such as Slick, or Sizzle), or a single node selected by whatever means.

It is however reccomended that you use moofx as part of a javascript library's api (see below).

moofx(document.querySelectorAll('div.box'));
moofx(document.querySelector('div#box'));
moofx(Slick.find('div#box'));
moofx(Slick.search('div.box'));
moofx(Sizzle('div.box'));
moofx(document.getElementById('box'));

moofx::animate

The animate method accepts either an object made of styles, or a property and a value, followed by the optional options object.

moofx(nodes).animate({'background-color': '#ffa', 'color': 'black'}); //animate some styles, default options

moofx(nodes).animate('background-color', '#ffa'); //animate property to value

moofx(nodes).animate({'background-color': '#ffa', 'color': 'black'}, {duration: 500}); //animate styles using options (500ms duration)

moofx(nodes).animate('background-color', '#ffa', {duration: 500}); //animate property to value using options (500ms duration)

moofx(nodes).animate({'background-color': '#ffa'}, {duration: 5000}); //5s duration

moofx(nodes).animate({'background-color': '#ffa'}, {duration: "5000ms", equation: 'cubic-bezier(0.17,0.67,0.83,0.67)'}); //5s duration, cubic-bezier easing equation

moofx(nodes).animate({'background-color': '#ffa'}, {duration: "5s", equation: 'ease-in'}); //5s duration, ease-in easing equation

moofx(nodes).animate({'background-color': '#ffa'}, {duration: "5s", equation: 'ease-in-out', callback: function(){ //5s duration, ease-in-out easing equation, completion callback
    console.log('animated');
}});

moofx::style

The style method accepts either an object made of styles or property and a value.

moofx(nodes).style({'background-color': 'red', 'color': 'black'});  //set styles

moofx(nodes).style('background-color', 'rgba(0,0,0,0)'); //set style property to value

moofx::compute

Computed style getter and normalizer. Note that lengths will always return in px (unless is "auto") and colors in rgba for consistency.

moofx(node).compute('background-color'); //get (normalized!) computed style of node for property

moofx.requestFrame / moofx.cancelFrame

moofx also provides an advanced requestAnimationFrame shim, that supports canceling and the standard time argument.

var callback = function(time){
    console.log(time);
};

moofx.requestFrame(callback); //sets callback to be executed on the next animationFrame
moofx.cancelFrame(callback); //whopsie, better not! callback will not get executed.

moofx.requestFrame(callback); //on second thought, let's do it
moofx.requestFrame(callback); //three
moofx.requestFrame(callback); //times

//and the time argument logged 3 times in your console will be the same, since the callbacks will get executed during the same animationFrame.

moofx.color

moofx also exports a simple any-to-rgb color converter, with a very basic, very straightforward usage:

moofx.color('#000'); //rgb(0, 0, 0)
moofx.color('#0000'); //rgba(0, 0, 0, 0)
moofx.color('#00000000'); //rgba(0, 0, 0, 0)

moofx.color('hsl(0, 0, 0)'); //rgb(0, 0, 0)
moofx.color('hsla(0, 0, 0, 0)'); //rgba(0, 0, 0, 0)

installation

Include the pre-built moofx.js (or moofx-min.js) in the webpage of choice. Use it. Love it. Done.

adapters

moofx was built to be used in conjuction with your favorite javascript framework. Some basic examples:

MooTools integration:

Element.implement('animate', function(){
    var moo = moofx(this);
    moo.animate.apply(moo, arguments);
    return this;
});

jQuery integration:

jQuery.fn.animate = function(){
    var moo = moofx(this.get());
    moo.animate.apply(moo, arguments);
    return this;
});

Then just get busy with your dollars.

BIY (build-it-yourself)

You can build moofx (+dependencies) from source with wrapup

npm install wrapup -g
mkdir webdev
cd webdev
npm install moofx
wrup -r moofx moofx -o moofx.js
wrup -r moofx moofx -o moofx-min.js -c

Alternatively, you can use the makejs node executable in this repo (you still need wrapup installed).
