javascript - 静态文件更新时， Angular 翻译重新加载静态文件？

Question

我将 CKEditor 与 AngularJS 结合使用进行内联编辑(使用 contenteditable)。

在 CKeditor 模糊的情况下，$http 请求会发送到服务器并更新数据库，特别是刚刚修改的相关字符串的翻译键/值对。

在服务器上，数据库中的字符串更新后，会触发构建系统，并通过轮询数据库来重写 [lang].json(静态文件)。

如何告诉 Angular-translate 然后重新加载 [lang].json？

我看过很多页面讨论部分重新加载，但我没有找到任何有关静态文件重新加载的信息。

这是该指令的作用。

.directive('frontOfficeEdit', [

        RESTIntranet, 
        $translate,
        $filter

    var counter = 0,
    prefix = '__ckd_';


    return {

                                // TRANSLATE IT?

            }, true); // - EOF - scope.$watch('editMode', function(newVal, oldVal) {

        }
        // - EOF - link
    }
    // - EOF - return
}]);

我没有足够的 JavaScript 经验来知道在哪里连接以及如何连接(对于异步内容还没有足够的经验)。谢谢。

我认为你只需要执行$translate.refresh()

https://github.com/angular-translate/angular-translate/blob/a2ac7000f94bcee6dd8e206cab5d7cec3527dd25/src/service/translate.js#L1584

   * @description
   * Refreshes a translation table pointed by the given langKey. If langKey is not specified,
   * the module will drop all existent translation tables and load new version of those which
   * are currently in use.
   *
   * Refresh means that the module will drop target translation table and try to load it again.
   *
   * In case there are no loaders registered the refresh() method will throw an Error.
   *
   * If the module is able to refresh translation tables refresh() method will broadcast
   * $translateRefreshStart and $translateRefreshEnd events.
   *
   * @example
   * // this will drop all currently existent translation tables and reload those which are
   * // currently in use
   * $translate.refresh();
   * // this will refresh a translation table for the en_US language
   * $translate.refresh('en_US');
