require.js: Access all loaded modules
提问by Michael
Is there any way to access all loaded modules of require.js?
有没有办法访问require.js的所有加载模块？
Background:
I want to automatically call an init()function of my javascript-modules after all of them are loaded, see require.js + backbone.js: How to structure modules that have an initialize function?Without require.js I looped over my own module-storage and called each init()function.
I now want to do this with require.js. I'm aware that calling a my_custom_init_function_favoritecolor_petname_love123of every loaded module (including external libraries) is dangerous. I hope that this will cause less trouble than manually keeping a list of all modules (and the requirements of these modules) up-to-date. Forgetting one module init() is much more likely than a third-party library having my custom function name (though the latter is probably harder to debug).
背景：
我想init()在加载所有 javascript 模块后自动调用它们的函数，请参阅require.js +backbone.js：如何构建具有初始化功能的模块？在没有 require.js 的情况下，我遍历了自己的模块存储并调用了每个init()函数。
我现在想用 require.js 做到这一点。我知道调用my_custom_init_function_favoritecolor_petname_love123每个加载的模块（包括外部库）是危险的。我希望这比手动保持所有模块的列表（以及这些模块的要求）最新会带来更少的麻烦。忘记一个模块 init() 比使用我的自定义函数名称的第三方库更有可能（尽管后者可能更难调试）。
Or does anyone have a better idea of how to accomplish that?
或者有没有人对如何做到这一点有更好的想法？

Yes, require.s.contexts._.definedis an object which its keys are the module names and the values include the value returned from that module.
是的，require.s.contexts._.defined是一个对象，其键是模块名称，值包括从该模块返回的值。
require.s.contexts._.definedincludes all the modules (either define()or require()such as the Javascript file that is the starting point of the program and is indicated using data-mainfor RequireJS).
require.s.contexts._.defined包括所有的模块（或者define()或require()诸如JavaScript文件是程序的开始点，并使用被指示data-main为RequireJS）。

Just finished a similar behavior within my RequireJS project. require.s.contexts['_'].registryholds the list of the registered modules.
刚刚在我的 RequireJS 项目中完成了一个类似的行为。require.s.contexts['_'].registry保存已注册模块的列表。
I am using Underscore.jsfor getting, filtering and iterating the list of modules. Maybe the following code fragment helps you:
我Underscore.js用于获取、过滤和迭代模块列表。也许以下代码片段可以帮助您：
var modules_registered = _.keys(require.s.contexts['_'].registry);
var modules_to_be_initialized = _.filter(modules_registered, function(module_title) {
return module_title.indexOf('modules') > -1;
});
_.each(modules_to_be_initialized, function(module_name) {
require([module_name], function(current_module) {
current_module.init();
});
});

I'm lazy, so I just did this:
我很懒，所以我只是这样做：
var modulesToLoad = Object.keys(require.s.contexts['_'].registry);
require(modulesToLoad);
Based on other answers here.
基于此处的其他答案。
