Callbacks

gistfile1.js

// add a "fire" variable, below the self variable, that will cover both the current instance and the root variable.

var self = this,
    fire = root.add(self);

/////////////////////////

// then insert calls to the custom functions in all the necessary places, e.g. in the slide function --

$.extend(self, {

slide: function(where) {
    
    // Trigger the callback. You can also pass custom data into trigger events. Very useful for callbacks.
    fire.trigger("onSlide", [where]);
    
}

});

/////////////////////////

// callbacks -- add these after you extend self with your public methods.

$.each(['onSlide', 'anotherCallback', 'yetAnotherCallback'], function(i, name) {

	// configuration
	if ($.isFunction(conf[name])) { 
		$(self).bind(name, conf[name]); 
	}

	self[name] = function(fn) {
		if (fn) { $(self).bind(name, fn); }
		return self;
	};
