我对grunt concat和requirejs(以及typescript)有点问题。问题很简单,当我为每个类生成一个文件,并分别加载每个文件时,我没有问题。(但浏览器的速度较慢)示例:
- A.js
- 消息.js
- ValidatorMessage.js(扩展Message并具有依赖项)
loader.ts:
require.config({
paths: {
'A': '../generated/shared/A.min',
'Message': '../generated/shared/Message.min',
'ValidatorMessage': '../generated/shared/ValidatorMessage.min', }//more
这很管用。我可以在浏览器中要求()每个文件,然后我就得到了。但如果这样做:
require.config({
paths: {
'shared': '../generated/shared.min',
这行不通。
有共享的内容。min.js

我不明白是因为在同一个文件中有几个调用需要定义还是其他原因。你呢?
编辑:我忘了说,在这个例子中,类A将在浏览器端可用(并且可以工作),但不是下面的。如果我将A删除到shared.min.js,那么Message类将起作用,但下一个不起作用,所以我认为只有第一个类加载良好!
第2版:我还忘了说,在A不存在的情况下,浏览器中的var Message存在并工作(正如我在Edit1中所说),但var ValidatorMessage也存在!除了它没有定义之外,我的意思是我从浏览器中获得了自动完成,但里面什么都没有。看起来只有第一个define()将对象设置为全局对象。
您应该在生产中使用r.js优化器,而不是手动将文件连接在一起;否则,您将失去模块化代码的好处(每个文件一个类)。让优化器做艰苦的工作来计算依赖关系图,不要试图重新发明轮子!
这是一项艰巨的任务。
