If the div is updated using Prototype's Element#update, you could fire a
custom event from the update function to alert other scripts of the change:
(function() {
var oldUpdate = Element.Methods.update;
Element.addMethods({
update: function(element, html) {
element = $(element);
var oldHtml = element.innerHTML;
oldUpdate(element, html);
element.fire('dom:update', {prevValue: oldHtml, newValue: html});
return element;
}
});
})();
$('content').observe('dom:update', function(event) {
// update the scrollbar however
scrollbar.update();
});
