Asynchronous module definition(AMD) #8

Open IVYGOU opened 7 years ago

IVYGOU commented 7 years ago

Asynchronous module definition (AMD) is a specification for the programming language JavaScript. It defines an application programming interface (API) that defines code modules and their dependencies, and loads them asynchronously if desired.

AMD是“Asynchronous Module Definition”的缩写，意思就是“异步模块定义”。从名称上就可以看出，它是通过异步方式加载模块的，模块的加载不影响后续语句的执行，所有依赖加载中的模块的语句，都会放在一个回调函数中，等到该模块加载完成后，这个回调函数才运行。

Instead of loading files one after the other, AMD can load them all separately, even when they are dependent on each other.

define.amd 属性

为了清晰的标识全局函数（为浏览器加载script必须的）遵从AMD编程接口，任何全局函数应该有一个"amd"的属性，它的值为一个对象。这样可以防止与现有的定义了define函数但不遵从AMD编程接口的代码相冲突。
