Auto open accordian in asp.net

I have an asp/ajax accordion on my page. What I would like to do is have it open and close automatically and loop through. I did find a script that will change the selected index (this works fine)

 <script type="text/javascript">
         function pageLoad() {
             changeSelected(1);
         }

         // expand given accordion pane
         function changeSelected(idx) {
             $find('Accordion1_AccordionExtender').set_SelectedIndex(idx);
         }
    </script>

Is it possible to modify this script to... lets say every 30 seconds, open the next unselected index and so on until it's get to the end, then start over at 0?

Thanks for any help.

just an idea:

if you are sure about the number of panes, ...say 5

(UNTESTED CODE)

var idx=0;
changeSelected(); //for initial select

setInterval(changeSelected,30000);

 function changeSelected() {
if(idx>4) {  idx =0;}
             $find('Accordion1_AccordionExtender').set_SelectedIndex(idx); idx++;
         }

thanks. I'll try it and see if I can make it work... but I never know how many panes I'm going to have.

getting the count is easyy:

add  a server side function (C#)

 public int getCount(){
           return MyAccordion.Panes.Count();
       }

in js,

add one more variable for storing the count first;

var totalPanes = <%= getCount()%>;
var idx=0;
changeSelected(); //for initial select

setInterval(changeSelected,30000);

 function changeSelected() {
if(idx>totalPanes ) {  idx =0;}
             $find('Accordion1_AccordionExtender').set_SelectedIndex(idx); idx++;
         }
