当我在这个菜单中的子菜单上进行鼠标悬停时,我怎样才能将:悬停状态留在顶层?它可能很简单,但我似乎无法使它工作。我尝试过做mouseEnter,但我很可能做得不正确,因为我对jQuery知之甚少。提前谢谢!

如果你想看到这个Link漂亮的设计能够html / css(不需要javascript)菜单希望你喜欢它。

将$(this).addClass('hover');
添加到您的悬停输入功能,将$(this).removeClass('hover');
添加到您的悬停功能,并将li.hover{/* css specific to it */}
添加到您的CSS。
$curobj.hover(
function(e){
var $targetul=$(this).children("ul:eq(0)")
$(this).addClass('hover');
if ($targetul.queue().length<=1) //if 1 or less queued animations
if (this.istopheader)
$targetul.css({left: $mainmenu.position().left, top: $mainmenu.position().top+this._dimensions.h})
if (document.all && !window.XMLHttpRequest) //detect IE6 or less, fix issue with overflow
$mainmenu.find('ul').css({overflow: (this.istopheader)? 'hidden' : 'visible'})
$targetul.dequeue().slideDown(droplinemenu.animateduration.over)
},
function(e){
var $targetul=$(this).children("ul:eq(0)")
$(this).removeClass('hover');
$targetul.dequeue().slideUp(droplinemenu.animateduration.out)
}
) //end hover
或者,如果你想要一个纯CSS替代品。这是我使用每个网站的那个。
nav ul{
margin-bottom:10px;
list-style-image:none
}
nav>ul>li{
display:inline-block;/* float:left needed for some designs */
font-size:20px;
text-align:center;
position:relative;
z-index:950
}
nav a{
text-decoration:none;
display:block;
color:#000;
padding:8px 0
}
nav li ul{
display:none;
position:absolute;
padding:0 8px;
margin:0
}
nav li:hover ul{display:block}
nav li li{
font-size:15px;
float:none;
width:100%;
z-index:999
}
请注意,这是一个骨架,并且看起来不漂亮。
HTML也非常简单:
<nav>
<ul>
<li><a href="#">top level item</a>
<ul>
<li><a href="#">sub-item</a></li>
</ul>
</li>
<li>top level item</li>
</ul>
</nav>
