i18next jquery 帮助迁移到 i18next jquery v3.0.0

Question

大家好，

从 i18next jquery 1.11.1 迁移到 3.0.0 版我需要一点帮助 目前这是我的设置

<!-- Core JS files -->
<script type="text/javascript" src="../js/jquery-2.2.4.min.js"></script>
<script type="text/javascript" src="../js/i18next.min.js"></script> (v1.11.1)

$(function(){
    // i18next Configuration
    // -------------------------
    var namespaces = ["nav" ,"common" ];
    var options = {
            ns: {
                namespaces: namespaces,
                defaultNs: namespaces[0]
            },
            resGetPath: '../assets/locales/__ns__/__lng__.json',
            debug: false,
            load: 'unspecific',
            detectLngQS: 'lang',
            fallbackLng : 'en',
            cookieName: 'applang',
            //cookieExpirationTime : ,
            useLocalStorage: false,
            cookieDomain: '*.mydomain.com',
            useCookie: true,
            lngWhitelist: ['en','es', 'de', 'fr']
        };
    i18n.init(options ,function (err,t) {
        $('body').i18n(); // Init 18n

    });
})

当我想加载额外的命名空间时，我会这样做

var namespaces = ["newFile"];
i18n.loadNamespaces(namespaces, function (err, t) {
        // init i18n
        $('body').i18n();
   .............. other stuff in here
})

但是当我尝试使用最新的 i18next v3 和 jquery-i18next (https://github.com/i18next/jquery-i18next) 保持相同的逻辑时，我在 loadNamespaces 函数上遇到错误（未捕获的 TypeError：namespaces.forEach 不是函数），下面是新设置

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.js" ></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/i18next/3.0.0/i18next.min.js" ></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-i18next/0.0.2/i18next-jquery.min.js" ></script>

i18next
  .use(i18nextXHRBackend)
  .init({
      lng: 'de',
      backend: {
          loadPath: '../assets/locales/{{lng}}/{{ns}}.json'
      }
    }, function(err, t) {
      jqueryI18next.init(i18next, $);
      $('.body').localize();

  });

  var namespaces = ["newFile"];
  i18n.loadNamespaces(namespaces, function (err, t) {
        // init i18n
        $('body').localize();
   .............. other stuff in here
})
