How can I use translations in i18next in javascript

Question

I know that I can use i18next to translate languages in html. For example:

<div data-i18n="someKey"></div>

But is there a way to somehow use it in JS. For example if I want to do something like

alert(someKey) ?

Answer 1

It should be alert(t(someKey)) (see http://i18next.com/ at end of page).

Answer 2

Having read the homepage of the project...

i18n.init(function(t) {
    // translate nav
    $(".nav").i18n();

    // programatical access
    var appName = t("app.name");
});

That last part is what you're looking for. It's important to note that that t is passed to the init callback as a parameter - you can't just blindly call t() anywhere ;)
