Get attribute of objects in an array

Question

For some reason, jQuery isn't giving me the attributes of objects in array when I define the number in the array. It will return the class of the first object in an array when none in particular are defined, though. For example, this works:

$('#content').prepend($('div #left ol.group li',data).attr("class"));

but this doesn't:

$('#content').prepend($('div #left ol.group li',data)[3].attr("class"));

Can someone explain to me why this doesn't work like most other functions do and how to make it work?

with jQuery get the index by using eq

$('#content').prepend($('div #left ol.group li',data).eq(3).attr("class"));

This would be a +1 if you told him why as well as what. :-) (E.g., because when you index into the jQuery object, what you get back is a raw DOM element, not a jQuery object.)

Accessing an individual element of a jQuery set using the indexer returns a DOM object, which doesn't have the .attr() method. You want .eq(3), which returns a jQuery object wrapping that individual element.
