场景:使用的框架是主干和需要。我有一个 main.js,它对 util、model 和 view js 有几个依赖关系,它们又是相互依赖的。还有循环依赖。此 main.js 已使用 requirejs 优化器编译为单个文件。
问题: 如何在运行时覆盖某些视图和模型? (我有一个 main 的编译版本,所以我不是在谈论在编译时排除模型或视图的 js)。
在编译时我不知道模型/视图是否会被覆盖。因此,当我运行优化器时,会创建一个包含所有模型和视图的 js 文件。我需要覆盖该单个 js 文件中的特定类定义,这样我就不会修改该文件。
是否有任何配置会告诉“要求”从单独的文件而不是单个编译的 js 文件加载模型/视图?
或者有什么办法可以通过最小的变化来实现?

//mymodel.js - filename

return mymodel2;

define([
'jquery',
'underscore',

var mymodel2 = Backbone.Collection.extend({

//like this i have view2.js, view3.js... etc
//Similarly i have util folder with util1.js, util2.js... etc
//main.js
