jQuery jSlots – Lucky 7's!

Options

These are the options, with their default values, and what they do

$.jSlots.defaultOptions = {
    number : 3,          // Number: number of slots
    winnerNumber : 1,    // Number or Array: list item number(s) upon which to trigger a win, 1-based index, NOT ZERO-BASED
    spinner : '',        // CSS Selector: element to bind the start event to
    spinEvent : 'click', // String: event to start slots on this event
    onStart : $.noop,    // Function: runs on spin start,
    onEnd : $.noop,      // Function: run on spin end. It is passed (finalNumbers:Array). finalNumbers gives the index of the li each slot stopped on in order.
    onWin : $.noop,      // Function: run on winning number. It is passed (winCount:Number, winners:Array, finalNumbers:Array)
    easing : 'swing',    // String: easing type for final spin. I recommend the easing plugin and easeOutSine, or an easeOut of your choice.
    time : 7000,         // Number: total time of spin animation
    loops : 6            // Number: times it will spin during the animation
};

Usage

Attach jQuery (successfully tested down to v1.4.1)

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>

Attach jSlots plugin

<script src="jquery.jSlots.js" charset="utf-8"></script>

Attach easing plugin (optional but HIGHLY recommended for nice animation)

<script src="jquery.easing.1.3.js" charset="utf-8"></script>

Create a list and an element that will spin the slots

<ul class="slot">
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
    <li>6</li>
    <li>7</li>
</ul>

<!-- this button will start the spin -->
<input type="button" id="playBtn" value="play">

Target the list and make it a jSlot!

<script type="text/javascript" charset="utf-8">

    $('.slot').jSlots({
        spinner : '#playBtn',
        winnerNumber : 7
    });

</script>

Styling is up to you, but jSlots supplies a jSlots-wrapper div around your lists that should get overflow: hidden and a height set on it. Here are some recommended styles:

.jSlots-wrapper {
    overflow: hidden; /* to hide the magic */
    height: 20px; /* whatever the height of your list items are */
    display: inline-block; /* to size width correctly, can use float too, or width*/
    border: 1px solid #999;
}
