如何包括Bootstraps JS依赖项

Question

我想在我的Angular 7应用程序中包含Bootstrap 4。我做了npm install bootstrap --save并且CSS样式工作正常，但是当我想使用按钮作为自举程序折叠的导航栏时，该按钮没有反应。我认为这是因为Bootstrap在这种情况下取​​决于jquery和popper.js。我尝试通过npm install jquery --save和npm install popper.js --save手动添加它们。但是即使在那之后，我也无法在node_modules文件夹中找到这些模块，也不知道如何包含这些依赖项。

我们将不胜感激。谢谢。

这有效

  

检查 WORKING STACKBLITZ

执行npm安装：〜 npm i bootstrap jquery --save

  

选项1

     

在angular.json中添加以下内容：〜

    "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
    ],
    "scripts": [
      "node_modules/jquery/dist/jquery.min.js",
      "node_modules/bootstrap/dist/js/bootstrap.min.js"
    ],

  

选项2

     

在您的index.html

中添加以下链接和脚本

  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
