The issue isn't so much that s is no longer in scope, but rather the
variable is getting captured rather than the specific variable.
What I would suggest doing is define a method in your application like
this:
def make_image_link(s)
link(s, :click => Proc.new { window { image s } })
end
And then set things up like this:
['http://foo.com', 'http://bar.com'].each do |s|
make_image_link(s)
end
This way, rather than a loop variable (which gets recycled between
loops), the Proc will capture a variable unique to the call to
make_image_link.
