Fx.Ticker

Make a number in the innerText of a DOM Element smoothly change from one value to another. This is like tweening a style value, but instead you tween the html content integer value.

You may also provide a transformation function in the options, which is useful for prepending zeroes or simulating float values for example.

How to use

HTML

<span id="myCounter">0</span>

JAVASCRIPT

// Create the Ticker like any other Fx
var numberTicker = new Fx.NumberTicker('myCounter');
numberTicker.start(0,100);

// or use shorthand version
$('myCounter').numberTicker(100);

// also, you can provide any of Fx options, plus a transformer function :
$('myCounter').numberTicker(100, {
    duration: 5000,
    transformer: function(i) {
        // Prefix with zeroes so we have a 5 digits number
        return (Array(5).join('0') + i).slice(-5);
    }
});
