如何使推特引导菜单下拉悬停而不是点击

我想有我的引导菜单自动下拉悬停，而不是必须点击菜单标题。我还想去掉菜单标题旁边的小箭头。

使用jQuery会更好:

jQuery('ul.nav li.dropdown').hover(function() {
  jQuery(this).find('.dropdown-menu').stop(true, true).show();
  jQuery(this).addClass('open');
}, function() {
  jQuery(this).find('.dropdown-menu').stop(true, true).hide();
  jQuery(this).removeClass('open');
});

用这个脚本覆盖bootstrap.js。

jQuery(document).ready(function ($) {
$('.navbar .dropdown').hover(function() {
    $(this).addClass('extra-nav-class').find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();
}, function() {
    var na = $(this)
    na.find('.dropdown-menu').first().stop(true, true).delay(100).slideUp('fast', function(){ na.removeClass('extra-nav-class') })
});

$('.dropdown-submenu').hover(function() {
    $(this).addClass('extra-nav-class').find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();
}, function() {
    var na = $(this)
    na.find('.dropdown-menu').first().stop(true, true).delay(100).slideUp('fast', function(){ na.removeClass('extra-nav-class') })
});

});

内联使用两个链接。用下拉按钮隐藏链接，并在可见链接上添加onmouseover事件以单击下拉菜单。

<a class="pretty-button"
   href="#" alt="Notifications"
   onmouseover="$('#notifications-dropdown').click()">
</a>

<a style="display:none"
   id="notifications-dropdown"
   class="js-nav js-tooltip js-dynamic-tooltip"
   href="#"
   alt="Notifications"
   data-toggle="dropdown">
   <span class="fa fa-flag fa-2x"></span>
</a>

我基于最新的(v2.0.2) Bootstrap框架创建了一个纯悬停下拉菜单，它支持多个子菜单，我认为我应该发布给未来的用户:

body { padding-top: 60px; padding-bottom: 40px; } .sidebar-nav { padding: 9px 0; } .dropdown-menu .sub-menu { left: 100%; position: absolute; top: 0; visibility: hidden; margin-top: -1px; } .dropdown-menu li:hover .sub-menu { visibility: visible; } .dropdown:hover .dropdown-menu { display: block; } .nav-tabs .dropdown-menu, .nav-pills .dropdown-menu, .navbar .dropdown-menu { margin-top: 0; } .navbar .sub-menu:before { border-bottom: 7px solid transparent; border-left: none; border-right: 7px solid rgba(0, 0, 0, 0.2); border-top: 7px solid transparent; left: -7px; top: 10px; } .navbar .sub-menu:after { border-top: 6px solid transparent; border-left: none; border-right: 6px solid #fff; border-bottom: 6px solid transparent; left: 10px; top: 11px; left: -6px; } <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/css/bootstrap.min.css" rel="stylesheet" /> <div class="navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container-fluid"> <a data-target=".nav-collapse" data-toggle="collapse" class="btn btn-navbar"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a href="#" class="brand">Project name</a> <div class="nav-collapse"> <ul class="nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Link</a></li> <li><a href="#">Link</a></li> <li><a href="#">Link</a></li> <li class="dropdown"> <a data-toggle="dropdown" class="dropdown-toggle" href="#">Dropdown <b class="caret"></b></a> <ul class="dropdown-menu"> <li> <a href="#">2-level Dropdown <i class="icon-arrow-right"></i></a> <ul class="dropdown-menu sub-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li class="nav-header">Nav header</li> <li><a href="#">Separated link</a></li> <li><a href="#">One more separated link</a></li> </ul> </li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li class="nav-header">Nav header</li> <li><a href="#">Separated link</a></li> <li><a href="#">One more separated link</a></li> </ul> </li> </ul> <form action="" class="navbar-search pull-left"> <input type="text" placeholder="Search" class="search-query span2"> </form> <ul class="nav pull-right"> <li><a href="#">Link</a></li> <li class="divider-vertical"></li> <li class="dropdown"> <a class="#" href="#">Menu</a> </li> </ul> </div> <!-- /.nav-collapse --> </div> </div> </div> <hr> <ul class="nav nav-pills"> <li class="active"><a href="#">Regular link</a></li> <li class="dropdown"> <a href="#" data-toggle="dropdown" class="dropdown-toggle">Dropdown <b class="caret"></b></a> <ul class="dropdown-menu" id="menu1"> <li> <a href="#">2-level Menu <i class="icon-arrow-right"></i></a> <ul class="dropdown-menu sub-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li class="nav-header">Nav header</li> <li><a href="#">Separated link</a></li> <li><a href="#">One more separated link</a></li> </ul> </li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </li> <li class="dropdown"> <a href="#">Menu</a> </li> <li class="dropdown"> <a href="#">Menu</a> </li> </ul>

                </div>
            </li>
        </ul>
    </div>
</nav>

还有CSS

.dropdown {
    float: left;
    padding-right: 1px;
}

.dropbtn{
    border: 0px;
    height: 30px;
    border-radius: 0px 10px;
}
li button, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
}

li button:hover, .dropdown:hover .dropbtn {
    background-color: #12A5F4;
}

.dropbtn.active {
    background: #12A5F4;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #e8f3f4;
    min-width: 100%;
    box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.1);
    z-index: 10;
}

.navbar-header{
    overflow: visible;
    z-index: 1;
}

.dropdown-content a {
    color: black;
    padding: 5px 10px;
    display: block;
    text-align: left;
}

.dropdown-content a:hover {
    background-color: #d8dee2
}

.dropdown:hover .dropdown-content {
    display: block;
}

#menubar{
    padding-top: 5px;
    overflow: visible;
    z-index: 10;
    padding-left: 0px;
    padding-right: 0px;
    margin: 0px;
}

#dropdownNavbar{
    margin: 0px;
}

.navbar-toggle{
    background-color: #3382d5;
}
.navbar-toggle span{
    background-color: white;
}

使用以下代码在鼠标悬停时打开子菜单(仅适用于桌面):

$('ul.nav li.dropdown').hover(function () {
    if ($(window).width() > 767) {
        $(this).find('.dropdown-menu').show();
    }
}, function () {
    if ($(window).width() > 767) {
        $(this).find('.dropdown-menu').hide().css('display','');
    }
});

如果你想让第一关菜单是可点击的，甚至在手机上也可以添加这个:

    $('.dropdown-toggle').click(function() {
    if ($(this).next('.dropdown-menu').is(':visible')) {
        window.location = $(this).attr('href');
    }
});

子菜单(下拉菜单)将打开鼠标悬停在桌面上，点击/触摸移动和平板电脑。 一旦子菜单打开，第二次单击将让您打开链接。 多亏了if ($(window).width() > 767)，子菜单将在移动设备上采用全屏宽度。
