Hello,
I try to make a visual effect "toggle" on a list generated
automatically
from a controller, I''ve tried this but that doesn''t work? the
id
"answer_<%=i%> isn''t recognized I think?
<%i=0%>
<%@questions.each do |question|%>
<h1 class="question">
<%= link_to_function(question.description) do |page|
page.visual_effect :toggle_appear,
''answer_<%=i%>''
end%>
</h1>
<p id="answer_<%=i%>">
<%=question.answer%>
</p>
<%i=i+1%>
<%end%>
Thank you for your help,

thank you Fred,
I''ve changed so this in my code but that works only for the first
title;
if I click on another title, it''s always the description of the first
title that disappears/appears? I would like to make a
appearition/disappearition of the description linked to the title
concerned.
<%i=0%>
<%@questions.each do |question|%>
<h1 class="question">
<%= link_to_function(question.description) do |page|
page.visual_effect :toggle_appear, ''answer_#{i}''
end%>
</h1>
<p id="answer_#{i}">
<%=question.answer%>
</p>
<%i=i+1%>

Hi, On Apr 29, 1:54 pm, san 1981 <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> <%i=0%> > <%@questions.each do |question|%> > <h1 class="question"> > <%= link_to_function(question.description) do |page| > page.visual_effect :toggle_appear, ''answer_#{i}'' > end%> > </h1> > > <p id="answer_#{i}"> > <%=question.answer%> > </p> > <%i=i+1%>You''ve nearly got it, but you''re confusing ERB scope and ruby scope. Also strings surrounded with single quotes in ruby don''t get interpolated, you need double quotes. Finally you don''t need your index variable i when you could use each_with_index instead. <%@questions.each_with_index do |question, i| %> <h1 class="question"> <%= link_to_function(question.description) do |page| page.visual_effect :toggle_appear, "answer_#{i}" end %> </h1> <p id="answer_<%=i%>"> <%=h question.answer%> </p> <% end %> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This could arguably be simplified even further with the
content_tag_for and dom_id methods. Something like this (untested):
<% @questions.each do |question| %>
<% content_tag_for :h1, question do
link_to_function(question.description) do |page|
page.visual_effect :toggle_appear, dom_id(question, "answer")
end
end %>
<% content_tag_for :p, question, "answer" do %>
<%=h question.answer%>
<% end %>
<% end %>
Search the Rails API docs for dom_id and content_tag_for.
