I am working with the Yahoo Maps API and I''d like to only include the
Yahoo javascript library on demand. I have a link_to_remote that shows a
Yahoo Map. Rather than <script src> the Yahoo library on every page it
seems more efficient to load this as part of my RJS partial ("on
demand").
Is this possible? It doesn''t seem like it. Can <script src> be
honored
by a browser when returned from an AJAX call?
When I load the Yahoo js library as part of the regular HTTP page it
works fine.
Thanks!

> or the RJS way: > > insert RJS way here...I''m using RJS. It''s quite simple actually... I have my Yahoo Map stuff all in a partial, so with RJS I simply have: def ymap render :update do |page| page.replace_html ''map'', :partial => ''ymap'', :locals => {:place => Place.find(params[:id])} end end The javascript include <script src> stuff is at the top of the partial. The browser doesn''t seem to be obeying it though. I''ll try some different methods such as what you suggested. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For one thing I can''t find any reference to "type" or "src" methods for DOM elements.> or the shorter prototype way: > > new Insertion.Bottom(''id_of_place_u_want_it'', script)This does not work either. Apparently prototype doesn''t support external scripts. There''s a patch for it but Rails/Prototype don''t seem to be interested: http://dev.rubyonrails.org/ticket/6722 It does work fine when I include the javascript on the original page whether a map is ever loaded or not, but there''s a noticeable hit on the page loading times. :( -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you have firefox developer toolbar installed, go to the view source tab, then "view generated source" and it will show you that the <script> tag was appended to the bottom of the <head> tag. <html> <head> </head> <body> <script type="text/javascript"> script = document.createElement(''script''); script.id = ''newScript''; script.type = ''text/javascript''; script.src = ''yahoo_stuffs.js''; document.getElementsByTagName(''head'')[0].appendChild(script); </script> </body> </html> You are creating a new page element and assigning it to the variable script. id, type and src are attributes you''re setting on that page element object. you could do: script.madeupcrap = "stuff"; and it would write out an attribute like: <script type="text/javascript" madeupcrap="stuff"></script> Copy and paste the code into just an html doc and run it in your browser. If you''re scripts aren''t being eval-ed on return of your link_to_remote call, that might be the issue. Set your RJS return to do an alert or something to let you know the request was sent back: alert(''i worked, yay!''); or something. Also, the Firebug plugin for Firefox is great to debug ajax requests with. Shows you what happened round trip. Hope u get it working :-) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I found a couple threads on a Prototype mailing list discussing it. At any rate, I may just leave it in the original page. It should be cached I believe, so I''m now wondering if it''s worth all the trouble... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
