How a js script can get the current locale from my rails app?

I am not very fluent in JS, so I don’t see how to transfer the rails
app current locale …

I have a JS script able to detect the default browser language …
running fine

I can also modify the JS language, passing a global var …

// Create a JSON Object
var myJSON = {
“lang”: “fr”
};
// Pass it to the script immediately…
datePickerController.setGlobalVars(myJSON);

and it runs … but I would like this script to use the language
selected by the rails app user :
the I18n.default_locale being modified in the rails app

any clue ?

thanks a lot …

Couldn’t you pass that back in your page’s view template?
