Detecting jquery-ui accordion open / close state

Question

How do I conditionally handle when an accordion section is open. What I am asking is this (in pseudo code):

if (this-accordion-section-open){
   do something
}
else {
   do something else
}

I am looking for something like :isvisible.

Thanks for your help.

following code return you the active panel,

var active = $( ".selector" ).accordion( "option", "active" );
