Mike Alsup:

Thanks for your work on jQuery Cycle.

I have a question about some of the code. I'm trying to build a carousel where partial images are displayed, so I'm digging into custom transitions, and before and after callbacks. The carousel is gonna be fine, but I found some code that I don't understand in the plugin.

In the transitions included in the plugin, before and after are arrays. Is it possible to stack a bunch of callbacks onto these options? Or does Cycle assume that the options may have 1 callback and the transition may add 1 more? In buildOptions , only one of the callbacks is called for each of these options and I don't understand why these specific ones are called.

   
      // fire artificial events
      var e0 = $slides[first];
      if (opts.before.length)
        opts.before[0].apply(e0, [e0, e0, opts, true]);
      if (opts.after.length > 1)
        opts.after[1].apply(e0, [e0, e0, opts, true]);
   

I did my best to find the origin of these lines, but it appears to be pre-github. They exist in the original commit to your repo.

Cheers,
