the problem is that yield(instance) is yielding the currenct action (index) and it should add methods to the helper method scope



index.html


<%= tabs 1000 do |t| %>
  <% t.tab "Tab1" do %>
    aaa
  <% end %>
  <% t.tab "Tab2" do %>
    bbbb
  <% end %>
<% end %>






module TabsHelper

  def tabs(offset, &block)
    instance = JqueryUiTab.new(offset)
    yield(instance)
    html =  "<div class='ui-tabs'>"
    html += "<ul>"
    instance.array.each do |h|
      html += "<li><a href='#tabs-#{h[:tab_id]}'>#{h[:name]}</a></li>"
    end
    html += "</ul>"
    instance.array.map do |h|
      html += "<div id='tabs-#{h[:tab_id]}'>#{h[:proc].call}</div>"
    end
    "#{html}</div>"
  end

end


class JqueryUiTab
  def initialize(i=0)
    @i = i
    @array = []
  end
  
  attr_reader :array
  
  def tab(name, &block)
    @i += 1
    @array << {:name=>name, :proc => block, :tab_id=>@i}
  end
end
