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"];
Or
I18n.alpha.bravo;
