Bootstrap 4-保持下拉列表的父级为可点击链接

Question

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</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 mr-auto">
      <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="#">Link</a>
      </li>
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <div class="dropdown-divider"></div>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</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">Search</button>
    </form>
  </div>
</nav>

引导程序的新手。这是基于Bootstrap示例的代码。现在会显示下拉列表，但您无法单击下拉列表本身。我希望能够使所有父级导航链接正常工作。类似于此网站：https : //eastcfashion.com/

例如，在其中单击：男士系列会将您带到该地区的所有系列。但是，在下拉菜单中，您只能进行特定的项目。

我正在尝试以主要的父母导航说Projects的方式来实现它。然后项目的下拉菜单将显示每个项目的特定页面，例如项目1，项目2等。但是单击“项目”会将您带到项目1，项目2和项目集合将显示为一组的页面而不是单独。

Answer 1

最简单的方法是从父元素中删除“data-toggle”属性！编辑：感谢提示，这里是一个代码示例：我改变了这个：

<a class="p-2 text-dark dropdown-toggle" data-toggle="dropdown" style="font-size:1.25rem;" href= {% url 'link' %}>Link</a>

对此：

<a class="p-2 text-dark dropdown-toggle" style="font-size:1.25rem;" href= {% url 'link' %}>Link</a>

因此，本质上，我只是删除了数据切换属性，从而将可悬停的下拉列表转换为带有可点击父链接的可悬停下拉列表。

Answer 2

我试图保持代码简单。我的解决方案是检测下拉按钮/链接上的第二次点击，然后点击该链接。

$('.navbar .dropdown > a').click(function() {
 if (!$(this).hasClass("parent-clicked")) {
    $(this).addClass("parent-clicked");
  } else {
    location.href = this.href;
  }
});

这也适用于折叠视图。

Answer 3

jQuery(function($) {
  if ($(window).width() > 769) {
    $('.navbar .dropdown').hover(function() {
      $(this).find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();

    }, function() {
      $(this).find('.dropdown-menu').first().stop(true, true).delay(100).slideUp();

    });

    $('.navbar .dropdown > a').click(function() {
      location.href = this.href;
    });

  }
});

@media only screen and (min-width:769px) {
  .dropdown:hover .dropdown-menu {
    display: block;
  }
  .dropdown-submenu {
    position: relative !important;
  }
  .dropdown-submenu>.dropdown-menu {
    top: 0 !important;
    left: 100% !important;
    margin-top: -6px !important;
    margin-left: -1px !important;
    border-radius: 0 !important;
  }
  .dropdown-submenu:hover>.dropdown-menu {
    display: block !important;
  }
  .dropdown-submenu>a:after {
    display: block;
    content: "\f105";
    font-family: 'FontAwesome';
    margin-top: -18px;
    right: 15px;
    position: absolute;
    font-weight: 300;
  }
}
