I have a project which I want to translate into multiple languages for the PHP Part I use Zend Frameworks Zend_Translate with GetText. Now I want to translate the JS part too.>
Well, you could extend strings to give them a translated-function, which looks up the receiver in a locale.
You would use it like this:
alert("Your favorite language is English!".translated());
And you would be given an alert with "tu idiom prefiero es Espanol", or something
