javascript - angular.module 和 window.angular.module 之间有什么区别吗？

Question

我正在审查以下内容:

(function () {
    'use strict';

    window.angular
          .module('moduleName')
          .directive('DirectiveName', function () {
            return {
                restrict: 'AE',
                templateUrl: '/app/moduleName/list/template.html',
                controller: 'someController',
                controllerAs: 'someCtrl',
            }
        });
}());

我一直在用

angular
    .module('myModule')
    //etc

而不是从 window.angular 开始。

因为我假设 angular 的作用域是针对窗口的，所以这两种语法之间有什么真正的、实际的区别吗？

完全没有。在浏览器窗口中是全局对象，

如这里所写 - https://developer.mozilla.org/en-US/docs/Web/API/Window/window :

In web pages, the window object is also a global object. This means that:

• global variables of your script are in fact properties of window:

  var global = {data: 0};
  alert(global === window.global); // displays "true"
  

• you can access built-in properties of the window object without having to type window. prefix:

  setTimeout("alert('Hi!')", 50); // equivalent to using window.setTimeout.
   alert(window === window.window); // displays "true"
