Javascript requirejs中每个已加载依赖项的回调？

我想在RequireJS加载javascript库时调用一个函数。我将使用它向用户指示初始初始化。通常只需不到一秒钟，但如果需要更长的时间，用户就会盯着空白屏幕，认为web应用程序出了问题。我想象这样的画面：

我能赶上失败的：

requirejs.onError = function(error) {
  error.requireModules.forEach(function(name) {
    //Create basename in case this was an URL
    name.replace(/^.*[/]/, "");
    // Debug
    console.warn("Module failed to load: ", name);
    // Find the loading node (they are hardcoded) and 
    // if it exists mark it as failed
    var element = document.getElementById("loading_"+name);
    if(element) {
      element.className+=" failed";
    }
  });
}

var require = {
    deps: ["some/module1", "my/module2", "a.js", "b.js"],
    callback: function(module1, module2) {
        //This function will be called when all the dependencies
        //listed above in deps are loaded. Note that this
        //function could be called before the page is loaded.
        //This callback is optional.
    }
};

这样我就可以在图像上准备弹出窗口，并在其中报告故障。但报道成功也很重要。现在有一个选项我不想使用：

requirejs.onError = function(error) {
  error.requireModules.forEach(function(name) {
    //Create basename in case this was an URL
    name.replace(/^.*[/]/, "");
    // Debug
    console.warn("Module failed to load: ", name);
    // Find the loading node (they are hardcoded) and 
    // if it exists mark it as failed
    var element = document.getElementById("loading_"+name);
    if(element) {
      element.className+=" failed";
    }
  });
}

var require = {
    deps: ["some/module1", "my/module2", "a.js", "b.js"],
    callback: function(module1, module2) {
        //This function will be called when all the dependencies
        //listed above in deps are loaded. Note that this
        //function could be called before the page is loaded.
        //This callback is optional.
    }
};

因为：

• 它仅在加载所有依赖项时执行，而不是在每个依赖项上执行
• 如果我的依赖项发生变化，它将形成另一个我必须更新的位置（并且我必须使它与我的加载弹出窗口保持同步）

我想要的是与

onError

相反。每次成功加载模块时调用回调。它对于调试目的也很有用
