如何在 Angular 中使用 Bootstrap 导航栏

Question

我在我的 Angular 应用程序的引导程序中使用导航栏示例，但导航栏根本没有出现。

这是导航栏 html

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <a class="navbar-brand" href="#">Navbar</a>
  <div class="collapse navbar-collapse" id="navbarNavDropdown">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricing</a>
      </li>
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown link
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
    </ul>
  </div>
</nav>

我已经安装了引导程序 npm install bootstrap --save

并在styles.css中导入引导程序 @import '~bootstrap/dist/css/bootstrap.css';

请帮忙谢谢

Answer 1

试试这个
-> 通过 npm install --save bootstrap 安装引导程序 -> 在 .angular-cli.json 中的样式添加"../node_modules/bootstrap/dist/css/bootstrap.min.css",将是这样的

"styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "styles.css"
      ],

或添加

    <script src="https://cdnjs.cloudflare.com/ajax/libs/ng2-bootstrap/x.x.x/ng2-bootstrap.min.js"></script>

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">

或通过路径 <link rel="stylesheet" type="text/css" href="../node_modules/bootstrap/dist/css/bootstrap.min.css"/??>

希望对你有用
