我制作的这个 Bootstrap 菜单很糟糕，我不明白为什么它不会折叠、动画。一切都很好，但按钮不起作用。 <nav class="navbar navbar-expand-lg navbar-light bg-dark alb"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <!-- Logo pentru desktop --> <a href="index.html" class="logo"> <img src="img/logo.png" alt="IMG-LOGO"> </a> <div class="collapse navbar-collapse" id="navbarTogglerDemo03"> <ul class="navbar-nav mr-auto mt-2 mt-lg-0"> <li class="nav-item active"> <a class="nav-link" href="#" style="color:white">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#" style="color:white">Marci moto</a> </li> <li class="nav-item"> <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true" style="color:white">Sectiune dezactivata</a> </li> </ul> <form class="form-inline my-2 my-lg-0"> <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit" style="color:white">Cautare</button> </form> </div> </nav>

我使用了与您相同的代码，并且仅在我的代码中使用在线 CDN，它对于您提供的相同代码运行良好。将你的代码与我的代码进行比较，找出错误所在。
以下是我的代码片段：
<!DOCTYPE html>

<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<body>
<nav class="navbar navbar-expand-lg navbar-light bg-dark alb">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a href="index.html" class="logo">
<img src="img/logo.png" alt="IMG-LOGO">
</a>
<div class="collapse navbar-collapse" id="navbarTogglerDemo03">
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item active">
<a class="nav-link" href="#" style="color:white">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#" style="color:white">Marci moto</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true" style="color:white">Sectiune dezactivata</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit" style="color:white">Cautare</button>
</form>
</div>
</nav>
</body>
</html>
我希望这将帮助您解决您的问题。
