Bootstrap 5 内置Tab功能在Card组件内无法正常生效问题求助

问题原因 #

• Bootstrap 5 对交互属性做了命名空间更新，旧版本Bootstrap使用的data-toggle属性已失效，需要替换为data-bs-toggle
• 代码存在基础语法错误和类名缺失：
  • 导航链接缺少nav-link类导致样式异常
  • 活跃状态的tab面板需要同时加active和show类才能正常显示，旧版的in类已在Bootstrap 5中废弃
  • Card内嵌Tab的代码中id="dhcp"、id="static"漏写了末尾的双引号，<form>标签重复定义了class属性

正确实现方案 #

1. 基础Tab功能实现 #

<div class="container network_wrapper col-sm p-2 ">
    <h2>Dynamic Tabs</h2>
    <ul class="nav nav-tabs">
        <li class="nav-item">
            <a class="nav-link active" data-bs-toggle="tab" href="#home">Home</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" data-bs-toggle="tab" href="#menu1">Menu 1</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" data-bs-toggle="tab" href="#menu2">Menu 2</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" data-bs-toggle="tab" href="#menu3">Menu 3</a>
        </li>
    </ul>

    <div class="tab-content">
        <div id="home" class="tab-pane fade show active">
            <h3>HOME</h3>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor
                incididunt ut labore et
                dolore magna aliqua.</p>
        </div>
        <div id="menu1" class="tab-pane fade">
            <h3>Menu 1</h3>
            <p>Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex
                ea commodo consequat.
            </p>
        </div>
        <div id="menu2" class="tab-pane fade">
            <h3>Menu 2</h3>
            <p>Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque
                laudantium, totam rem
                aperiam.</p>
        </div>
        <div id="menu3" class="tab-pane fade">
            <h3>Menu 3</h3>
            <p>Eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta
                sunt explicabo.</p>
        </div>
    </div>
</div>

2. Card内嵌Tab实现 #

<div class="container network_wrapper col-sm p-2 ">
    <div class="card">
        <div class="card-header">
            <h5 class="card-title">Network Settings</h5>
            <ul class="nav nav-tabs card-header-tabs">
                <li class="nav-item">
                    <a class="nav-link active" aria-current="true" data-bs-toggle="tab" href="#dhcp">DHCP</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" data-bs-toggle="tab" href="#static">Static</a>
                </li>
            </ul>
        </div>
        <form class="card-body">
            <div class="tab-content">
                <div class="tab-pane fade show active" id="dhcp">
                    <p class="card-text">Change DHCP Network settings.</p>
                </div>
                <div class="tab-pane fade" id="static">
                    <p class="card-text">Change Static Network settings.</p>
                </div>
            </div>
            <button class="btn btn-primary mt-3" type="submit">Save</button>
        </form>
    </div>
</div>

不需要额外自定义JS代码，保持你现有的Bootstrap 5 CSS和JS引入即可正常运行。
