Just count them in the controller method you invoke as you add them.
Store
the count in a session variable or in a table to persist your count.

I have a following code in add.rjs
count = 0
page.select(’#results li’).each do |element|
count = count + 1
#element.hide
end
page.insert_html :bottom, ‘results’, "
" + count.to_s}
page.visual_effect :highlight, count.to_s, :duration => 2.5
and following in view
and i always get count = 1

I’m not sure I understand exactly what it is you’re trying to
accomplish,
but in general… I would recomment keeping track of ‘count’ in your
controller method; storing / retrieving it there and making it available
to
your view via an instance variable. You’re not dealing with a static
page
of which you have no knowledge. Everything that’s on the page is put
there
by your app during the session. No?

Yes, if i work with dynamic pages i can save elements count to session,
but my question is connected with static pages.
For example designer add one element to div, and i set count variable in
controller to 1, but when designed add new element to div, again i need
to change count variable.
i just want to know is it possible count some elements, for example
where are they located.
maybe anybody can give a advice how to set id of new element to unique
value(i guess i can user time(in milliseconds) for example)
Thanks
Hi Igor
In an action in the controller, responding to the xhr request when you
do
render :update to |page|
I just did a page.inspect in the log and found @content_for_layout - I
think
you would have to do something like page.session.content_for_layout -
the
log is pretty ugly - you can check.
But, if you have @content_for_layout you could count the occurance of
However, this sounds very convoluted - you would probably be better of
just
adding the milliseconds id for the li.
