you should not use js with erb, it meet serious problem when you change variable rails without change js. You can use client variable gem, checkout more details https://github.com/Coffa/client_variable

Hi again.

I would like to pass an instance variable to "HERE!!!" in  'save.js.erb'

$('#listtrans').html(
  '<%= escape_javascript(render :partial => "videos/script_list",
:locals => { :scripts => Script.find_all_by_video_id(HERE!!!) } ) %>
');

If I put a specific value, video_id, (18 in this case ) like

$('#listtrans').html('<%= escape_javascript(render :partial =>
"videos/script_list", :locals => { :scripts =>
Script.find_all_by_video_id(18) } ) %>');

works fine.  Of course, this must be generalized.

So I tried,

$('#listtrans').html('<%= escape_javascript(render :partial =>
"videos/script_list", :locals => { :scripts =>
Script.find_all_by_video_id(<%= @video.id %>) } ) %>');

gives an error


ActionView::Template::Error
(/Users/ishidasouichi/Dropbox/Rails/script_youtube/app/views/videos/save.js.erb:3:
syntax error, unexpected '<', expecting ')'
...> Script.find_all_by_video_id(<%= @video.id );@output_buffer...

Also, I tried

@video.id
params[:video_id]
and so on.

Any idea?

Thanks in advance?
