JS prototype get class within known element

[likwid]

Hi

Can someone please answer me a quick question which is taking too long to find on the net.

With prototype I can find elements easily by className or id but how do i find an element within a know element.

eg

$$(".someClass").each(function(elmt) { });

where I want to find elements of classname 'someClass' within an element already stored.

Many thanks in advance.

Exactly what i was looking for but somehow unable. Thanks for your help!

I generally have a terrible time with api's if i'm honest, probably due to my lack of patience.

One more question. If I have an js object, how can i get the first element of it without using a for in loop.

eg

obj['some1']['some2']

How can i get 'some1' returned without using for .. in? I'm guessing it's possible but realise javascript is limited compared with other languages.

Thanks again.

Thanks for reply.

I'm referring to a data object, which to my understanding is actually an array in javascript. What you describe, obj[0] is pretty much exactly what I am looking for but it seems not to work, unless i'm doing something wrong.

Another problem I'm having..

	$('sidebar').select($$('div')).each(function(me){me.remove()})

This is removing anything within the sidebar, instead of just div's.

Help's appreciated.

oh, figured it out by removing the dollar signs from the select. :S
