Question

我正在使用Angular 2框架构建一个Web应用程序，我想使用外部模板（https://freehtml5.co/preview/?item=splash-free-html5-bootstrap-template-for-any-websites）。

我需要在我的组件模板中运行一些脚本（jquery.min.js，bootstrap.js，...）但是如果我把它放到脚本标签中则不起作用。

如果我在index.html中运行脚本标记，它可以工作，但是当我浏览到另一个页面脚本时，不会重新加载。

如何在模板中加载没有脚本标记的脚本？

的index.html

Answer 1

如果您正在使用Angular CLI，则可以在.js的{{1}}中添加node_modules个文件。

在.angular-cli.json数组下方和styles上方，您应该看到environmentSource数组。我已将JSON的一些内容（我已将其截断）作为您的参考。

我认为不允许在角度2组件内加载脚本标签，但看看它可能会对您有所帮助 How do I include a JavaScript file in another JavaScript file?

Answer 3

组件模板中不允许使用脚本标记。在index.html中包含脚本应该使它们可以全局访问。当你说你正在浏览另一个页面时，你的意思并不清楚，但如果你使用带有router-outlet的角度路由器，你导入的所有脚本都应该是可访问的。
