angular - 如何将外部 JS 文件包含到 angular5？

Question

我是 Angular 的新手，并从这个 tutorial 开始学习 angular5 .

我正在将普通的 HTML 模板转换为 Angular 5 版本，现在我在将外部 JS 文件添加到 Angular 5 项目时遇到困难。

任何人都可以帮我将外部 js 文件添加到 angular5 项目吗？

这是我更新的 angular.json 文件。仍然不适合我。

您可以通过 scripts 将 Javascript 文件添加到全局范围angular.json 中项目构建目标选项中的选项.这些将被加载，就像您将它们添加到 <script> 中一样。index.html 中的标记。

<script src="path to your js file"></script>

或

您可以指定要包含在构建中的全局脚本，在您的 Angular 项目的angular.json 文件脚本数组

(angular-cli.json 文件，如果你的 Angular 版本是 < 6.0)。

{
  "scripts": [
    // path to your js file
  ]
}
