Hi all, I was looking at this ticket: http://dev.rubyonrails.org/ticket/6265 and it got me thinking: is there any reason we''re not using the tasty ActiveSupport::JSON encoder to assemble options for the various helper methods in PrototypeHelper and ScriptaculousHelper? At the moment, they use options_for_javascript() in JavaScriptHelper, which is a half-hearted JSON generator that doesn''t handle strings vs. literals very well, let alone nested hashes, arrays, etc. The result is a bunch of scattered JSON-generating code in the individual helper method...

How can I check to see if an element has been created? I could then put

Hello there, This is my first post to the Ruby group. I am also new to the language and the Rails framework, it is an amazing place to be now. Coming from a PHP/ASP background I am glad something like Rails finally made it into web development. Now to my question. I have been readying a lot about AJAX, and I wondered what kind of support is built-in into Rails for it. I read somewhere that

In java/c++ the method signature provide a good details on which parameters the method accept, but in rails the ability to send hash as parameters make it impossible to know which parameters can be send. This ability make the rails API doc a must to be full of details and not supply partial examples of usage. When for example I see *link_to_remote*(name, options = {}, html_options = {}) I would

hi guys, I am testing a new optional funtionality in my site with IE 8 after success with Firefox 3.6.3, chrome and safari.
