I'd change

addEvent(window,'load',pageLoad);

to

window.onload = function() {
      pageLoad();
};

hielo,

Your solution works but what if there is more than 1 divs? I tried below but not working:

function pageLoad() {
      collapseAll( [$('mydiv1', 'mydiv2')]);
}

Any solutions?

 

by: hieloPosted on 2008-11-21 at 08:25:47ID: 23014367

try:

function pageLoad() {
      collapseAll( [$('mydiv1'), $('mydiv2'), $('mydiv3') ] );
}
