如何将外部 JS 文件包含到 angular5？

Question

我是 angular 的新手，并开始从本教程学习 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项目时遇到了困难。

谁能帮我将外部 js 文件添加到 angular5 项目中？

这是我更新的 angular.json 文件。仍然不适合我。

/*angular.json*/

scripts 您可以通过项目构建目标选项中的选项将 Javascript 文件添加到全局范围angular.json。这些将完全加载，就像您将它们添加到<script> index.html 内的标签中一样。

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

或者

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

（如果您的 Angular 版本 < 6.0，则为 angular-cli.json 文件）。

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