hi all,

I'm trying to do a each on an array the droppable element <%= draggable_element "user_" + create_drop_zone(zone),                                     :revert => true,                                     :onStart => "function(){" %>                                         <% drop_zone_ids.each do | zone> %>                                             Element.addClassName('<%= zone %>', 'border');                                         <% end %>                                         Element.addClassName('user_<%= user_node %>', 'move_user'); }

This results in: //<![CDATA[ new Draggable("user_1_4", {onStart:function(){, revert:true}) //]]> </script> Element.addClassName('3', 'border'); Element.addClassName('4', 'border'); Element.addClassName('user_1_4', 'move_user'); }

Someone knows how to solve this?

thanks Stijn

You need to drop down to regular Ruby string interpolation. Try this:

  <%= draggable_element "user_" + create_drop_zone(zone),        :revert => true,        :onStart => "function(){#{           drop_zone_ids.map do |zone|             "Element.addClassName('#{zone}', 'border');             Element.addClassName('user_#{user_node}', 'move_user');             "           end}           }" %>
