Rails: Internationalization of Javascript Strings?

Why not something simple like:

<script type="text/javascript">
  window.I18n = <%= I18n.backend.send(:translations).to_json.html_safe %>
</script>

Then in JS you can do things like:

I18n["en-US"]["alpha"]["bravo"];

I've wrapped mine in an application helper.

def current_translations
  @translations ||= I18n.backend.send(:translations)
  @translations[I18n.locale].with_indifferent_access
end

Then my call in my application.html.erb looks like this:

<script type="text/javascript">
  window.I18n = <%= current_translations.to_json.html_safe %>
</script>

This allows you to avoid having to know the current locale in JavaScript.

I18n["alpha"]["bravo"];

I18n.alpha.bravo;

Balibu is abandoned. Use i18n-js: https://github.com/fnando/i18n-js

Ryan's solution above is perfect, except the backend needs to be initialized if it hasn't been already.

I18n.backend.send(:init_translations) unless I18n.backend.initialized?
# now you can safely dump the translations to json
