In modern web applications data is being transferred through AJAX requests using JSON format. Previously we were not translating JSON format, so some parts of the website was staying untranslated.
Not any more!
Now we made it possible to define which keys in JSON object can be translated. You may check the GTranslate TDN Documentation for more technical information. This feature helps GTranslate to provide deeper translation of your website.
If you need help implementing this feature for your website you may contact ClickFWD who can help you. They have already made it possible for JReviews extension for Joomla.
