I have been reading the documentation at:
http://www.sergiopereira.com/articles/prototype.js.html
One of the examples does this:
var someNodeList =
$(''lstEmployees'').getElementsByTagName(''option'');
var nodes = $A(someNodeList);
nodes.each(function(node){
alert(node.nodeName + '': '' + node.innerHTML);
});
How can I access the array index as well as the node value? The
reference mentions that the Enumerable.each() function (I assume this
is the same one) can access the index, but I don''t quite see it.
I''m
sure it''s something incredibly obvious that I''ll end up
smacking
myself over... but who knows?
Thanks again guys.

I believe you simply have to include a second parameter to your iterator
function (which will be the index).
nodes.each(function(node, index){
alert(node.nodeName + '': '' + node.innerHTML);
});

I suppose that would make sense....

Nah, a lot of these things aren''t obvious or well documented. You just have to look through the code sometimes =). -----Original Message----- From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org [mailto:rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Greg Militello Sent: Thursday, February 09, 2006 2:58 PM To: rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org Subject: Re: [Rails-spinoffs] each() I suppose that would make sense....
