在bootstrap导航栏中,如何激活导航链接 (只需更改导航链接的bg颜色) 当导航链接的相应下拉列表打开时 或下拉菜单链接悬停? 我尝试了以下代码
$('ul.nav li.dropdown').hover(function() {
$(this).find('.dropdown-menu').stop(true, true).delay(50).fadeIn(50);
}, function() {
$(this).find('.dropdown-menu').stop(true, true).delay(50).fadeOut(50);
});

.navbar-nav li a{
color: #000;
text-transform: uppercase;
padding: 13px 10px;
text-align: center;
}
.navbar-nav li a:hover{
background-color: #238500;
color: #fff;
}
.dropdown-menu li a{
font-weight: normal !important;
padding: 15px !important;
color: #fff !important;
text-transform: capitalize !important;
text-align: left !important;
}
ul.dropdown-menu li a:hover{
background-color: #3c3c3c;
color: #fff;
background-image: none;
}
.dropdown-menu > li > a:focus, .dropdown-menu > li > a:hover{
background-image: none;
}
ul.dropdown-menu li a:hover > .navbar-nav li a{
background-color: #238500 !important;
}
.dropdown-menu{
background-color: #238500;
}

</li>

试试这个:
$('ul.nav li.dropdown').hover(function() {
$(this).find('.dropdown-menu').stop(true, true).delay(50).fadeIn(50);
$(this).addClass("hover");
}, function() {
$(this).find('.dropdown-menu').stop(true, true).delay(50).fadeOut(50);
$(this).removeClass("hover");
});

根据我的理解,这是你想要的吗?
.navbar-nav .open>a,
.navbar-nav .open>a:focus,
.navbar-nav .open>a:hover {
background-color: #238500 ;
color: #fff;
}
只需在CSS中添加此样式。
