我正在使用Angular 2框架构建Web应用程序,并且我想使用外部模板(https://freehtml5.co/preview/?item=splash-free-html5-bootstrap-template-for-any-websites)。
我需要在组件模板中运行一些脚本(jquery.min.js,bootstrap.js等),但是如果我将其放入脚本标签中将无法正常工作。
如果我在index.html中运行scripts标签,它可以工作,但是当我浏览到另一个页面时,脚本不会重新加载。
如何在模板中加载没有脚本标签的脚本?
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">

最佳答案
如果您使用的是Angular CLI,则可以将.js
中的node_modules
文件包括在.angular-cli.json
中。
在styles
数组下方和environmentSource
上方,您应该会看到scripts
数组。我包括了一些JSON(已将其截断)作为您的引用。
{
"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"
}
}
]
}
