Help understanding jQuery button enable/disable code

Question

I grabbed this code form JCarousel and just trying to understand these lines below. I\'m new to jQuery and not that great at JavaScript so I am not sure what is jQuery and

Answer 1

[n ? 'bind' : 'unbind']

Is an if statement, which can be rewritten as

if (n) // if n is true
{
   'bind';
}
else
{
   'unbind';
}

So if n is true, it would evaluate like this

this.buttonNext.bind((this.options.buttonNextEvent, this.funcNext))

because [ ] notation is the same as . notation.

buttonNext[bind] is the same as buttonNext.bind

To summarize what you posted, it checks the states of variables (n and p) which holds the state of the button. If it is enabled, then when activated it disables it, adds the disabled classes, etc. If it's disabled, it sets it to enabled and removes the disabled class.
