Coursera - 学习 Angular - 为什么我无法获得我的应用程序.js加载

Coursera - Learn Angular - Why can't I get my app.js load?

本文关键字：我的 应用程序 js 加载 Angular 学习 为什么 Coursera      更新时间：2023-09-26
到目前为止，我已经按照给我

的说明输入了HTML代码。但是当我尝试加载页面时，它只给了我：

选项卡：菜单开胃 菜电源甜点

说明： 图片： dish.name ， dish.name ， 菜品标签 ， 菜品价格 |货币 ， 菜品.描述

我

以为这可能是我正在运行的 angular 版本，但我刚刚下载了最新版本，但它仍然不起作用。我尝试将文件移动到与html文件相同的目录中，同样的问题。然后，我尝试将角度代码和应用程序代码放在html文档本身中，结果仍然相同。我什至删除了缓存，认为这将是问题所在，但仍然具有相同的观点。

我知道这是愚蠢的，但我的大脑被炸了，我看不到树木的森林。所有的css加载都很好。这只是应用程序.js没有加载。我将在下面包括主文件.html然后是应用程序.js文件，以获取任何进一步的提示。我正在尝试进入课程中我学习 Grunt 的部分（因此有构建/最终构建注释。因此，我将非常感谢一些帮助。

您遗漏了用于初始化页面中角度ng-app

改变 

<html lang="en">

自

<html lang="en" ng-app="confusionApp">

这正是已经说过的。我缺少 ng 应用程序变量。当我将其从一个文件传输到下一个文件时，我一定丢失了它。再次感谢。
