Hi,
When I run that with Prototype 1.6.0.2, the first alert gives me the
expected result ("2"). If you're seeing different behavior, perhaps
it's related to a version of Prototype, or...?
Two other things I noticed:
1. You're creating global variables ("selects1", "selects2", and
"id"). You probably want to use "var" within the function so they're
local variables. More on the horror of implicit global variables in
this blog post:
http://blog.niftysnippets.org/2008/03/horror-of-implicit-globals.html
2. Note that "for..in" is for iterating properties of objects, not
elements of arrays, although most of the time you can get away with
thinking that it does elements of arrays. There are many times when
that will break, though, and one of times (but by no means the only
one) is if you're using Prototype. More here:
http://www.prototypejs.org/api/array
Hope this helps,
