Re: [jQuery] what does options mean ???

$.Events = function(options, callback)

This defines a function called $.Events that takes 2 parameters. When
you see a parameter named options, you can usually assume that it
represents a hash. When you see a param named callback, it means that
the function expects either the name of some function or an anonymous
function block.

$.Events({ duration: duration }, function(){ ...});

This is an example of the function being called. The 2 parameters
passed are a hash ( { duration: duration } ) and an anonymous
function.

So, if you wish to pass more/different options, include them in the
hash that's passed here, eg:

$.Events({ duration: duration, foo: bar }, function(){ ...});
