Documentation

Basic usage

HTML:

<div id="carousel">
  <img class="cloud9-item" src="images/1.png" alt="Item #1">
  <img class="cloud9-item" src="images/2.png" alt="Item #2">
  <img class="cloud9-item" src="images/3.png" alt="Item #3">
  <img class="cloud9-item" src="images/4.png" alt="Item #4">
  <img class="cloud9-item" src="images/5.png" alt="Item #5">
  <img class="cloud9-item" src="images/6.png" alt="Item #6">
</div>

<div id="buttons">
  <button class="left">
    ←
  </button>
  <button class="right">
    →
  </button>
</div>

CSS:

#carousel .cloud9-item, #buttons button {
  cursor: pointer;
}

JavaScript:

$("#carousel").Cloud9Carousel( {
  buttonLeft: $("#buttons > .left"),
  buttonRight: $("#buttons > .right"),
  autoPlay: 1,
  bringToFront: true
} );

Carousel options

You may pass these options to the carousel constructor. Some of these properties may be changed during runtime via the data handle.

Reflection options

After including reflection.js in your page, you may pass in options to configure the item reflections. For example:

mirror: {
  gap: 12,     /* 12 pixel gap between item and reflection */
  height: 0.2, /* 20% of item height */
  opacity: 0.4 /* 40% opacity at the top */
}

Note: The reflection.js plugin does not work with Zepto, but this unofficial fork does!

Carousel methods

The following methods can be called on the carousel object after initialisation. For example:

// Spin three items clockwise
$("#carousel").data("carousel").go( 3 );

Event callbacks

Callback functions may be passed to the carousel constructor along with the options. For example:

// Hide carousel while items are loading
$("#carousel").css( 'visibility', 'hidden' ).Cloud9Carousel( {
  bringToFront: true,
  onLoaded: function( carousel ) {
    // Show carousel
    $(carousel).css( 'visibility', 'visible' );
    alert( 'Carousel is ready!' );
  },
  onRendered: function( carousel ) {
    var item = $(carousel).data("carousel").nearestItem();
    console.log( "Item closest to the front: " + $(item).attr("alt") );
  }
} );

Known issues

• Due to lack of standartisation, "mousewheel" scrolling is extremely sensitive and unmanageable when using some track pads (such as on the MacBook Pro). Unfortunately, since there appears to be no way to know directly what type of device is triggering the mousewheel events, it is not trivial to somehow normalise or "tame" the input from the track pad without also affecting the "1 tick per click" behaviour of the standard mouse wheel. darsain has described the same phenomenon in this discussion at the sly.js project. Ideas are appreciated.
