Rails - Jul 2006 - BIG JS limit? Using replace_html with partials containing JS

Hello,

It''s pretty hard giving a practical example on this one.

I have a partial which contains some generated Javascript.
Something like:


order_screen.rhtml
-------------------------------------------
<h1>Order</h1>

<div id="order_part">
<%=render :partial=>''order_new'' %>
</div>

<h1>Ordered products</h1>

<div id="order_lines_part">
  <p>Please finalise the order information first...</p>
</div>
--------------------------------------------

And...

order_edit.rhtml
-------------------------------------------
<h2>Order id: <%=@order.id %></h2>

<div id="order_message"><%=@order_message%></div>

<%= form_remote_tag :update=>''order_part'',
                    :url=> { :id=>@order.id, :action =>
''order_update''}
%>
  <%= render :partial=>''order_form'' %> </p>
  <%= submit_tag ''Modify''  %>
<%= end_form_tag %>

<%update_page_tag do |page|
     page.delay(2) do
       page.visual_effect :fade, ''order_message''
     end
   end
%>

<%=update_page_tag do |page|
     page.replace_html ''order_lines_part'', 
:partial=>''order_lines_index'',
                                           :locals=>{ :fade_message => 
false}
   end
------------------------------------------------------

I am having tons and tons of problems, because order_line_index.rhtml 
contains:

order_line_index.rhtml
------------------------------------------------------
<% no_message ||= false %>

<h2>Order id: <%=@order.id %></h2>

<div id="order_lines_message"> AH
<%=@order_lines_message%></div>

<%      update_page_tag do |page|
        page.delay(3) do
          page.visual_effect :fade, ''order_lines_message''
        end
      end
    end
%>

<%  render :partial=>''order_lines_form''
%>

<% for @order_line in @order.order_lines %>
  <li><%=@order_line.price%></li>
  [...]
<% end %>
---------------------------------------------------------

Basically, things don''t work because anything rendered using 
page.replace_html doesn''t seem to be able to contain any javascript, 
because the javascript code will be spit out on the page.

Do you know of any limits with page.replace_html? Can I only render 
partials which are STRICTLY html? If so, the limitation seems to be 
huge!

If you have any info, please let me know. I have lost it over this 
one...

Bye,

Merc.

I''d say it''s a limit of the browsers and their DOM
Implementations.
You may have to be creative here.  For instance replace the html and
then run fades, etc afterwards.  Use something like Event Selectors to
attach javascript events for any remote links/forms you may be
inserting.

Ouch. Can anybody else here confirm that you can''t have Javascript code
in a partial that is rendered by replace_html...?

This is important because my partials use Javascript of all sorts of 
things - auto-completion, lookup, etc.
This would really suck...

It''s not only pretty effects I am after!

Bye,

Merc.
