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。

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"
      }
    }
  ]
}
