angular - 如何包含 Bootstraps JS 依赖项

问题描述

我想在我的 Angular 7 应用程序中包含 Bootstrap 4。我做到npm install bootstrap --save了，css样式工作正常，但是当我想从引导程序中使用折叠导航栏的按钮时，按钮没有反应。我认为这是因为在这种情况下，Bootstrap 依赖于 jquery 和 popper.js。我试图通过npm install jquery --save和手动包含它们npm install popper.js --save。但即使在那之后，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。

帮助将不胜感激。谢谢。

解决方案

这有效

检查 工作堆栈闪电

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

选项1

添加以下内容angular.json：~

    "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

将以下链接和脚本添加到您的index.html

  <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>

也是我package.json的参考
