Try this:
var ItemScroller = Class.create({
initialize: function(el,options) {
// quit if no main element passed in
if (!$(el)) return;
this.options = Object.extend({
containerSelector: 'ul',
itemSelector: 'li',
viewPortSelector: '.wrap',
scrollerSelector: '.item_scroller',
nextSelector: '.next',
prevSelector: '.prev',
itemsPerScroll: 5,
wrapEnds: false,
mode: 'vertical'}, options || {});
}
});
new ItemScroller('foo');
new ItemScroller('bar', {itemsPerScroll:25});
