我开发了这个网站: http: //loloey.com/forme/formeeng.html 我在页面左上角名为“Change Universe”的下拉菜单中有一个非常奇怪的问题:当我多次悬停在这个下拉菜单上时,下拉元素消失!!!该问题在所有浏览器上都存在,例如 firefox、explorer 9、chrome 等。
我用一个简单的 jquery 代码创建了这个菜单:
$(document).ready(function () {
$('#nav li').hover(
function () {
//show its submenu
$('ul', this).stop().slideDown(100);
},
function () {
//hide its submenu
$('ul', this).stop().slideUp(100);
}
);
});
这是CSS:
/*---- CROSS BROWSER DROPDOWN MENU ----*/
#nav {
padding-left: 90px;
margin-top:-15px;
list-style: none;
float: left;
font-family: 'helveticaneuelight', Arial, sans-serif;
font-size: 9px;
color: #fff;
}
/* make the LI display inline */
/* it's position relative so that position absolute */
/* can be used in submenu */
#nav li {
float:left;
display:block;
width:70px;
background:#808184;
position:relative;
z-index:500;
margin:0 1px;
}
/* this is the parent menu */
#nav li a {
display: block;
padding: 5px 5px 4px 1px;
height: 11px;
text-decoration: none;
color: #58595B;
text-align: left;
}
#nav li a:hover {
color:#fff;
}
/* you can make a different style for default selected value */
#nav a.selected {
color:#f00;
}
/* submenu, it's hidden by default */
#nav ul {
position:absolute;
left:0;
display:none;
margin:0 0 0 -1px;
padding:0;
list-style:none;
}
#nav ul li {
width:70px;
float:left;
}
/* display block will make the link fill the whole area of LI */
#nav ul a {
display: block;
height: 15px;
padding: 4px 5px;
color: #58595B;
}
#nav ul a:hover {
text-decoration:none;
}
/* fix ie6 small issue */
/* we should always avoid using hack like this */
/* should put it into separate file : ) */
*html #nav ul {
margin:0 0 0 -2px;
}
这是html:
<div id="cambia">
<div class="top_a">CHANGE UNIVERSE:</div>
<ul id="nav">
<li><a href="#">FORME</a>
<ul>
<li><a href="../grandfloor/grandflooreng.html">GRANDFLOOR</a></li>
<li><a href="../gdo/gdoeng.html">GDO</a></li>
<li><a href="../parsi/parsieng.html">PARSI</a></li>
</ul>
<div class="clear"></div>
</li>
</ul>
</div>
有人帮助我吗?
