Question

有没有人知道为什么IE中的下拉菜单会在nivo滑块下消失？尝试玩z-index，没有帮助，我也知道下拉菜单在flash内容下消失，但事实并非如此（wmode = transparent）据我所知nivo滑块只使用jquery，没有闪存

这是html：

<table>
<tr height="50"><td colspan="2" align="right" class="bottom_menu">
<ul id="nav" class="dropdown dropdown-horizontal" >
                                             <li><a href="/index.cfm?fuseaction=home.logout" class="dir" style="border:0 !important;" >Çikis</a></li>   
                                             <li><a href="/index.cfm?fuseaction=objects2.list_basket" class="dir">Sepetim</a></li>
                                             <li><a href="/index.cfm?fuseaction=objects2.me" class="dir">Sirketim</a>
                                                <ul>

这是下拉菜单的css：

http://www.micae.com/documents/templates/projedepo/default.advanced.css

和nivo滑块：

http://www.micae.com/documents/templates/projedepo/banner/nivo-slider.css

和横幅div：

#banner { position:relative; width:980px; height:435px; background:#fff; margin-bottom:20px; margin-top:-1px; color:#000; z-index:60; }
.banner_img { padding:8px;position:absolute;z-index:2; }

和javascript默认情况下，jquery和nivo滑块

我忘了提及，没有定义doctype，那实际上是问题，任何想法如何解决？我的意思是没有doctype定义。因为当我定义doctype时，设计完全崩溃......

Answer 1

IE可以使用z-index做一些疯狂，特别是当元素没有定位时。确保故障元素及其所有祖先在css中明确定位或绝对定位。一旦某个链条出现中断，似乎就会创建一个全新的堆叠顺序。

个人而言，我的默认css中总是有这样的东西：

div, ul, li {position:relative;}

似乎解决了很多问题。

Answer 2

我遇到了同样的问题。只需确保将下拉列表css中的所有元素设置为具有非常高的z索引和显式定位（如同，请确保为每个元素指定 - relative-absolute-etc.）。对我来说，问题只发生在IE中，而不是firefox或chrome，但更改这些值（z-index> 300+）为我解决了问题。祝你好运，祝你好运！

nivo滑块和下拉菜单在IE中不起作用
