Hi,
I have a HTML like this :
....
In my controller, I have a “update_data” method, called every x
seconds from a periodical_call_remote :
I want to take all the elements having the class “data_1”, and replace
their html with :
render :partial => data_1, :local => {:user_id => user_id}, where
user_id is the id of the parent of p.data_1
But I didn’t find how to to catch the parents id of p.data_1 !
Does someone have an idea ?
Thank you
Thank you for your response but :
In this case, it will look for the element wich have the id “data_1”.
And if I have 50 users, I’ll have 50 “data_1” classes.
I would like a way to find the css equivalent of “#user_1 .data_1”
I tried :
page.select(“user_1”).each{|elt|
elt.select(“p.data_1”).each{|u_elt|
page.replace_html u_elt, “test”
}
}
But it doesn’t work…

I’m coming into this half way, but that selector you’ve got there is
wrong (that would select tags called user_1)
In pure prototype,
$(‘user_1’).select(‘p.data_1’).each(function(element){ …})
There are limits to what rjs can map to javascript, something like
page.select(’#user_1 p.data_1’).each {|elt| elt.update ‘test’}
would probably do it, but I’d probably stop fighting rjs and write it
by hand.

Found it ! 
render :update do |page|
page[‘user_1’].down(‘p.data_1’).replace_html “test”
end
It’s not the transcription of the prototype style you told me, but it
works…
I haven’t tried, but
$(‘user_1’).select(‘p.data_1’).each(function(element){ …})
should be
page[‘user_1’].select(‘p.data_1’)…
