html - 无法让引导导航切换器工作

问题描述

我正在尝试使用引导程序使以下几行工作，但是我遇到了一个困难，当我单击切换器时，什么也没有出现。当我将鼠标悬停在按钮上并单击时，该按钮似乎确实注意到了，但没有出现任何内容。我正在使用与以下官方页面相同的示例： https ://getbootstrap.com/docs/4.0/components/navbar/

如果有人能找出问题的帮助，将不胜感激。

我已确保问题与我的 CDN 链接无关，我希望我检查了所有可能的拼写错误。

       <nav class="navbar navbar-expand-lg navbar-dark bg-primary fixed-top navbar-default" id="sideNav">
    <a class="navbar-brand js-scroll-trigger" href="#page-top">
        <span class="d-block d-lg-none">Guy</span>
        <span class="d-none d-lg-block">
            <img class="img-fluid img-profile mx-auto mb-4" src="img/profile.jpeg" alt="">
        </span>
    </a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav">
            <li class="nav-item">
                <a class="nav-link js-scroll-trigger" href="#about">About</a>
            </li>
            <li class="nav-item">
                <a class="nav-link js-scroll-trigger" href="#awards">Curriculum Vitae</a>
            </li>
            <li class="nav-item">
                <a class="nav-link js-scroll-trigger" href="#experience">Portfolio</a>
            </li>
            <li class="nav-item">
                <a class="nav-link js-scroll-trigger" href="#education">Publications</a>
            </li>
        </ul>
    </div>

</nav>

解决方案

试试这个代码可能是你没有CDN以正确的格式使用。

替换：

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>

与：

 <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

您Style CDN在 head 标签内，而您script CDN在所有 html 代码之后。

让我知道这是否对您有用。
