在Angular 2项目中添加.js脚本 [英] Add .js scripts in Angular 2 project
问题描述
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 ）。
I am building a web app with Angular 2 framework and I want to use an external template (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。
I need to run some scripts (jquery.min.js, bootstrap.js, ...) in my components template but if I put it into scripts tag don't work.
如果我在index.html中运行脚本标签，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。
If I run scripts tag in index.html it works but when I browse to another page script are not reloaded.
如何在模板中加载没有脚本标记的脚本？
How can I load the scripts without script tag in template??

推荐答案
如果您使用的是Angular CLI，则可以包括来自 .angular-cli.json node_modules 中的 .js 文件$ c>。
If you're using the Angular CLI you can include .js files from your node_modules in your .angular-cli.json.
在 styles 数组下方和 environmentSource上方你应该看到脚本数组。我已经把JSON的一点点（我已经截断了它）作为参考。
Right under the the styles array and above the environmentSource you should see the scripts array. I've included a little bit (I've truncated it) of the JSON as reference for you.
{
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico"
],
"index": "index.html",
"main": "main.ts",
"styles": [
"styles.scss"
],
"scripts": [
"../node_modules/hammerjs/hammer.min.js"
],
"environmentSource": "environments/environment.ts",
"environments": {
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
]
}
