Dynamically add javascript tag to a view

Rails
1

Hi everybody,

I would like to add javascript tags dynamically to my view. So I used
the following code :

@events.each do |e|

      %(javascript_tag 'new

Popup(‘event_popup_#{e.id}’,‘event_link_#{e.id}’)’)

end

However it seems the code is not being added to my DOM.

How can I correctly code this ?

Thanks in advance.

%() declares a string literal, so nothing happens to your
javascript_tag. And
.each won’t return your string - even the correct one.

Try this eRB:

<%=
@events.map do |e|
javascript_tag “new
Popup(‘event_popup_#{e.id}’,‘event_link_#{e.id}’);”
end
%>

That still has its own style issues, including it will push several

tags in, not just one efficient one. You could also try this: <%= javascript_tag @events.map{|e| "new Popup('event_popup_#{e.id}','event_link_#{e.id}');" }.join %> So that puts the tag on the outside, and the "unrolled loop" on the inside. -- Phlip
