我有一个弹出菜单,(当然)在 FF/Chrome 中看起来很棒,但在 IE 中,它令人窒息。我在 JS Fiddle 上有一个完整的例子:http: //jsfiddle.net/JXw3S/4/
如果您将鼠标悬停在第二个 2 菜单项上,那里应该有一个弹出菜单。然而,在 IE 中,它似乎被#primaryMenu 容器的边界截断了。
如果 JSFiddle 不可用,这是我的代码:
HTML
<menu id="primaryMenu">
<ul>
<li class="active"><a href="#"><span>FMS</span></a><div class="arrow"><div></div></div>
<ul>
<li><a href="#">Project Accounts</a></li>
<li><a href="#">Non-Project Accounts</a></li>
<li><a href="#">DocID Log</a></li>
<li><a href="#">Gift Card Tracking</a></li>
<li><a href="#">PO/Account Reference</a></li>
<li><a href="#">Speedkey Reference</a></li>
</ul>
</li>
<li><a href="#"><span>Personel</span></a><div class="arrow"><div></div></div>
<ul>
<li><a href="#">Payroll</a>
<ul>
<li><a href="#">Report</a></li>
<li><a href="#">Analysis</a></li>
</ul>
</li>
<li><a href="#">Manage</a></li>
<li><a href="#">PI/Project Effort</a></li>
</ul>
</li>
<li><a href="#"><span>Facilities</span></a><div class="arrow"><div></div></div>
<ul>
<li><a href="#">Manage</a></li>
</ul>
</li>
</ul>
<a href="#" id="primaryMenuCollapse"><span>Collapse Menu</span></a>
</menu>
CSS:
#primaryMenu{display:block;position:fixed;left:0px;top:132px;z-index:90;padding:40px 0 0;margin:0;width:200px}
#primaryMenu ul{padding:0;margin:0;list-style-type:none}
#primaryMenu li{padding:0;margin:0;position:relative}
#primaryMenu a{font-size:0.95em}
#primaryMenu>ul{border-bottom:1px solid #aaa;position:relative}

#primaryMenu>ul>li.hovered>a>span{color:#fff;text-shadow:-1px 1px 0 #666}

#primaryMenu>ul>li.active>.arrow>div,
#primaryMenu>ul>li.hovered>a+.arrow>div{position: absolute;top: 0px;left: 0px;width: 14px;height: 32px;-webkit-border-top-right-radius: 20px;-webkit-border-bottom-right-radius: 20px;-moz-border-radius-topright: 20px;-moz-border-radius-bottomright: 20px;border-top-right-radius: 20px;border-bottom-right-radius: 20px}
#primaryMenu>ul>li>ul{display:none}
#primaryMenu>ul>li>ul>li>a,
#primaryMenu>ul>li>ul>li>ul>li>a{display:block;font-size:0.9em;padding:1px 10px;color:#444}
#primaryMenu>ul>li>ul>li>a:hover{color: #06e;}
#primaryMenu>ul>li.active>ul{display:block}
#primaryMenu>ul>li.hovered{}
#primaryMenu>ul>li.hovered>ul{display:block; position:absolute;width:140px;background:#fff;top:-1px;right:-141px;border-right:1px solid #aaa;border-bottom:1px solid #aaa;border-top:1px solid #aaa;z-index:1}
#primaryMenu>ul>li.hovered>ul>li>a{padding-left:20px}
#primaryMenu>ul>li.hovered>ul>li>a:hover,
#primaryMenu>ul>li>ul>li>ul>li>a:hover{background:#f0f6fd}
#primaryMenu>ul>li>ul>li>ul>li>a{padding-left:40px;font-size:0.8em;font-style:italic}
还有一点 JS 添加了一个悬停类
$('#primaryMenu>ul>li').hover(function(){
if($(this).hasClass('active')){}else
{
$(this).addClass('hovered')
}
},
function(){
$(this).removeClass('hovered')
});
