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?
