If you only want the child elements for a particular element, use this:
div id=whatever
ol
li
a href=#/a
/li
/ol
/div
Use this:
$$('#whatever ol')
.then, just use whatever enumerable you need to cycle through them.
On the flip-side, you can do it the way you wanted to, also
$('whatever').select('ol')
each should give you an array of the same elements.

Hi,
At first blush, it appears that the use of $$() might be problematic. I was
expecting to see something with Element.select(), which is described this
way in prototype-160-api.pdf: This method is very similar to $$() but can
be used within the context of one element, rather than the whole document.
Perhaps dropdown.select('ol') would yield the right set of elements?
all the best,

Hi all,
getting stuck with scope, I'm a bit new to javascript so would
appreciate the help!
I'm attempting to loop through each div class=ddBox and get the
highest ol in each div class=ddBox, then set the height of the
div class=ddBox to the highest ol. The problem is that its
looping through and getting the highest ol in the window.object and
applying this to each div. I'm sure its something simple but I'm
banging my head on the table here!
I've looked into binding but can't seem to get it right :(
div class=ddBox
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
/div
div class=ddBox
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
/div
div class=ddBox
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
ol
li
a href=#/a
/li
/ol
/div
$$('.ddBox').each(function(dropdown){
var ddHeight = $$('ol', this);
var ddBoxHeight = $$('.ddBox');
var max_height = ddHeight.invoke('getHeight').max();
ddBoxHeight.invoke('setStyle', {height: (max_height) + 'px'});
console.log(max_height);
},this);
Any help appreciated!
Cheers
Huck
