how can I get the I18n.default_locale selected in my Rails app in a JS script ?

[Erwin]

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 ..

Not sure I understand you correctly, but you could just do something like

<%=javascript_tag "window.locale = #{I18n.locale.to_s.inspect};" %>

in your page, and then do e.g.

alert(locale);

from a script.

Hi,

I sometimes have make a controller (or abuse something like a
pages_controller) to render a js view. In this view I place all the
initializers to other scripts. I keep all serious javascript into
static files which I can minimize and cache the hell out off.

Example:

# app/views/javascripts/show.js.erb
$(function() {
// Add datepickers to every date field
$('.date input').datepicker({
changeMonth : true,
changeYear : true,
dateFormat : '<%= t('.date_format') %>',
maxDate : '0'
});
});

# config/routes.rb
map.resource :javascript

# app/controllers/javascripts_controller.rb
class JavascriptsController < ApplicationController
def show; end # just render the view
end

# app/views/layouts/application.html.haml
= javascript_include_tag "jquery", "jquery.date-picker", :cache => true
= javascript_include_tag javascript_path(:format => :js)

This might be a bit more than you asked for, but this is how I pass
translations and such to javascript.

Check out this rails plugin,

ALmost identical to "Babilu" plugin, but this one is a bit more
customizable (say, for security reasons) and fully test-suit for the
paranoia:
