Question

我尝试为菜单中的每个链接添加一个切换按钮，以便在按下链接后在移动设备上关闭菜单。我通过向data-toggle="collapse" data-target="#navbarSupportedContent"添加<a href=""?>找到了解决方案。现在，此解决方案可以在引导程序3中使用，但在引导程序4中，它仍会关闭菜单，但不再链接到<a href="">中的文本。

为什么这会阻止从链接到链接，我该如何解决？

以下小提琴说明了问题，我在没有切换的链接和有切换的链接上方添加了注释。忽略它周围的所有内容，我敢肯定它周围的任何代码中都没有。

代码：

.block{
  height: 200px;
  padding: 100px;
  font-size: 30px;
  border-top: 3px solid gray;
}

.navbar li a {
  color: #bbb;
}

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
    <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 mr-auto container px-md-5">
            <!-- Links WITHOUT data-toggle -->
            <li data-menuanchor="block1">
                <a href="#block1">block1</a>
            </li>
            <li data-menuanchor="block2">
                <a href="#block2">block2</a>
            </li>
            <li data-menuanchor="block3">
                <a href="#block3">block3</a>
            </li>
            <!-- END of Links WITHOUT data-toggle -->
            <!-- Links WITH data-toggle -->
            <li data-menuanchor="block1">
                <a href="#block1" data-toggle="collapse" data-target="#navbarSupportedContent">block1 (with toggle+target)</a>
            </li>
            <li data-menuanchor="block2">
                <a href="#block2" data-toggle="collapse" data-target="#navbarSupportedContent">block2 (with toggle+target)</a>
            </li>
            <li data-menuanchor="block3">
                <a href="#block3" data-toggle="collapse" data-target="#navbarSupportedContent">block3 (with toggle+target)</a>
            </li>
            <!-- END of Links WITH data-toggle -->
        </ul>
    </div>
</nav>
      
<a name="block1"></a>
<div class="block" data-anchor="block1">block1</div>
<a name="block2"></a>
<div class="block" data-anchor="block2">block2</div>
<a name="block3"></a>
<div class="block" data-anchor="block3">block3</div>

我也愿意接受其他解决方案，例如JavaScript或html中的解决方案。

尝试一下

<div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
        <li class="nav-item dropdown">
            <a class="nav-link" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Menu Name 1 </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                <a href="#block1" class="dropdown-item">Submenu 1-1</a>
                <a href="#block2" class="dropdown-item"> Submenu 1-2</a>
                <a href="#block3" class="dropdown-item">Submenu 1-3</a>
            </div>
        </li> 


       <li class="nav-item dropdown">
            <a class="nav-link" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Menu Name 2 </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                <a href="#link1" class="dropdown-item"> Submenu 2-1</a>
                <a href="#link2" class="dropdown-item"> Submenu 2-2</a>
                <a href="#link3" class="dropdown-item"> Submenu 2-3</a>
            </div>
        </li> 
     </ul>
</div>

引导程序中的切换菜单会停止<a href="">
