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。

这样就把上面的隐藏起来了
.navbar .dropdown-menu:before {
display:none;
}
.navbar .dropdown-menu:after {
display:none;
}

在我看来,最好的办法是这样的:
;(function($, window, undefined) {
// Outside the scope of the jQuery plugin to
// keep track of all dropdowns
var $allDropdowns = $();
// If instantlyCloseOthers is true, then it will instantly
// shut other nav items when a new one is hovered over
$.fn.dropdownHover = function(options) {
// The element we really care about
// is the dropdown-toggle's parent
$allDropdowns = $allDropdowns.add(this.parent());
return this.each(function() {
var $this = $(this),
$parent = $this.parent(),
defaults = {
delay: 500,
instantlyCloseOthers: true
},
data = {
delay: $(this).data('delay'),
instantlyCloseOthers: $(this).data('close-others')
},
settings = $.extend(true, {}, defaults, options, data),
timeout;
$parent.hover(function(event) {
// So a neighbor can't open the dropdown
if(!$parent.hasClass('open') && !$this.is(event.target)) {
return true;
}
if(settings.instantlyCloseOthers === true)
$allDropdowns.removeClass('open');
window.clearTimeout(timeout);
$parent.addClass('open');
}, function() {
timeout = window.setTimeout(function() {
$parent.removeClass('open');
}, settings.delay);
});
// This helps with button groups!
$this.hover(function() {
if(settings.instantlyCloseOthers === true)
$allDropdowns.removeClass('open');
window.clearTimeout(timeout);
$parent.addClass('open');
});
// Handle submenus
$parent.find('.dropdown-submenu').each(function(){
var $this = $(this);
var subTimeout;
$this.hover(function() {
window.clearTimeout(subTimeout);
$this.children('.dropdown-menu').show();
// Always close submenu siblings instantly
$this.siblings().children('.dropdown-menu').hide();
}, function() {
var $submenu = $this.children('.dropdown-menu');
subTimeout = window.setTimeout(function() {
$submenu.hide();
}, settings.delay);
});
});
});
};
$(document).ready(function() {
// apply dropdownHover to all elements with the data-hover="dropdown" attribute
$('[data-hover="dropdown"]').dropdownHover();
});
})(jQuery, this);
样本的标记:
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" data-hover="dropdown" data-delay="1000" data-close-others="false">
Account <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a tabindex="-1" href="#">My Account</a></li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Change Email</a></li>
<li><a tabindex="-1" href="#">Change Password</a></li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Logout</a></li>
</ul>
</li>
如果你有这样一个下拉类的元素(例如):
<ul class="list-unstyled list-inline">
<li class="dropdown">
<a data-toggle="dropdown" href="#"><i class="fa fa-bars"></i> Dropdown 1</a>
<ul class="dropdown-menu">
<li><a href="">Item 1</a></li>
<li><a href="">Item 2</a></li>
<li><a href="">Item 3</a></li>
<li><a href="">Item 4</a></li>
<li><a href="">Item 5</a></li>
</ul>
</li>
<li class="dropdown">
<a data-toggle="dropdown" href="#"><i class="fa fa-user"></i> Dropdown 2</a>
<ul class="dropdown-menu">
<li><a href="">Item A</a></li>
<li><a href="">Item B</a></li>
<li><a href="">Item C</a></li>
<li><a href="">Item D</a></li>
<li><a href="">Item E</a></li>
</ul>
</li>
</ul>
然后你可以让下拉菜单自动下拉悬停,而不是必须点击它的标题,通过使用这段jQuery代码:
<script>
$('.dropdown').hover(
function() {
$(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn();
},
function() {
$(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut();
}
);
$('.dropdown-menu').hover(
function() {
$(this).stop(true, true);
},
function() {
$(this).stop(true, true).delay(200).fadeOut();
}
);
</script>
这是一个演示
这个答案依赖于@Michael的答案,我做了一些改变,并添加了一些补充,以使下拉菜单正常工作
这招对我很管用:
.dropdown:hover .dropdown-menu {
display: block;
}
还添加了margin-top:0来重置.dropdown-menu的引导css边距,这样当用户缓慢地从下拉菜单悬停到菜单列表时,菜单列表不会消失。
ul.nav li.dropdown:hover > ul.dropdown-menu {
display: block;
}
.nav .dropdown-menu {
margin-top: 0;
}
这适用于WordPress Bootstrap:
.navbar .nav > li > .dropdown-menu:after,
.navbar .nav > li > .dropdown-menu:before {
content: none;
}
