Bootstrap下拉式一级导航如何制作可点击的链接

6

我正在使用the-bootstrap wordpress主题创建一个带有下拉菜单的菜单，但是顶级链接只有在点击时才会显示下拉菜单而不是自己被点击时跳转到某个页面。所以，在www.thermoryuk.co.uk/wp/上，当我点击“地板”时，我想要跳转到地板页面并显示下拉菜单。以下是代码，请提前感谢您的帮助：

<nav class="subnav clearfix">
  <ul id="menu-product-menu" class="nav nav-pills pull-right">
    <li id="menu-item-87" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-87 dropdown" data-dropdown="dropdown">
      <a href="http://www.thermoryuk.co.uk/wp/?page_id=31" class="dropdown-toggle" data-toggle="dropdown">
        Flooring <b class="caret"></b>
      </a>
      <ul class="dropdown-menu">
        <li id="menu-item-88" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-88 dropdown-submenu" data-dropdown="dropdown">
          <a href="http://www.thermoryuk.co.uk/wp/?page_id=32" class="dropdown-toggle" data-toggle="dropdown">Ash Flooring</a>

          <ul class="dropdown-menu">
            <li id="menu-item-82" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-82">
              <a href="http://www.thermoryuk.co.uk/wp/?page_id=60">Ash Flooring Gallery</a>
            </li>
          </ul>
        </li>
        <li id="menu-item-89" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-89">
          <a href="http://www.thermoryuk.co.uk/wp/?page_id=34">Spruce Flooring</a>
        </li>
        <li id="menu-item-90" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-90">
          <a href="http://www.thermoryuk.co.uk/wp/?page_id=36">Birch Flooring</a>
        </li>
        <li id="menu-item-91" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-91">
          <a href="http://www.thermoryuk.co.uk/wp/?page_id=38">Pecan Flooring</a>
        </li>
      </ul>
    </li>
  </ul>
</nav>

我们可以简单地使用这段代码：

$('#sub-nav > ul > li > a').click( function() {

        location.href = $(this).attr('href');

    })

那是默认行为。导航栏通过点击而非悬停来激活。这就解释了为什么单击锚点会显示子菜单而不是跟随链接。此SO帖子中有一个解决方法。

谢谢，Dotty。如果我从“a”标签中删除了data-toggle属性，它似乎可以工作。我的jquery还不太行，我尝试使用$(document).off('.data-api','a');但是没有作用... - nihilster

我正在研究使用Bootstrap 3，通过为文本和下拉符号分配不同的链接，我能够在我的项目中实现这个效果：

<ul class="nav nav-pills nav-stacked left-menu" id="sub-nav">
  <li>
    <a href="/schools-departments">Schools &amp; Departments</a>
    <a href="javascript:void(0);" data-target="#item1" data-toggle="collapse" data-parent="#sub-nav" class="sub-drop"><span class="caret arrow"></span></a>
    <ul class="nav nav-stacked collapse left-submenu" id="item1">
      <li><a href="#">School of Arts &amp; Sciences</a></li>
      <li><a href="#">School of Education &amp; Behavioral Sciences</a></li>
      <li><a href="#">School of Health Sciences</a></li>
    </ul>
  </li>
</ul>

然后将这个添加到CSS中：

#sub-nav li a {
  display: inline-block;
}

稍作修改，可以实现下拉菜单的切换并在菜单下拉后再次点击以跟随父链接。

<script>
function clickMe(obj){ 
    if($(obj).data('clicked') == 'true'){
        location.href = $(obj).attr('href');
    }
     else{
    $(obj).data('clicked','true');
    }
}
</script>

添加一些HTML。

<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="dropdown">
 <a class="dropdown-toggle" data-toggle="dropdown" data-clicked="false" onclick="clickMe(this);" data-target="#" href="http://www.Add your link here.com">Link#1 <b class="caret"></b></a> 
 <ul class="dropdown-menu">....your drop down list here

js fiddle 尝试一下

我建议还要测试页面的宽度，这样移动端导航才能正常工作。因此，只有在页面宽度大于断点时才设置 location.href：

$('.navbar-collapse a.dropdown-toggle').click(function() {
  if($('body').width() >= "768") {
    location.href = $(this).attr('href');
  }
});

将此CSS添加到您的导航栏中。

<style>
ul.nav li.dropdown:hover ul.dropdown-menu{     display: block;     margin: 0 }
</style>

并添加属性

onclick="location.href='filename'"

 <a href="#" class="dropdown-toggle" onclick="location.href='filename'" data-toggle="dropdown"></a>

修改A标签如下：

<a class="dropdown-toggle" data-toggle="dropdown" data-clicked="false" onclick="clickMe(this);"  data-target="#">

在你的JS文件中添加如下代码：

function clickMe(obj){ 
    if($(obj).data('clicked') == 'true'){
        location.href = $(obj).attr('href');
    }
    else {
        $(obj).data('clicked','true');
    }
}

您可以通过从您的HTML标记中删除data-toggle="dropdown"来设置它。除此之外，我们还可以通过设置data-hover="dropdown"来使下拉菜单在鼠标悬停时工作。
