在响应式 css 菜单上获得多个级别时遇到问题,这是我在 tuts.com 上遵循本教程的菜单基础
我的网站在此菜单上需要 2 个以上的子级别,但是当我将额外的添加到 html 时,额外的级别无法正常工作,我确信可以在原始菜单中添加额外的级别,但我无法弄清楚我需要什么额外的 css,我曾尝试为 li li li li 添加额外的 css 代码,但这对我不起作用。
额外的级别与第 2 个子级别一起显示,它只应显示为第 2 个子菜单的悬停。
我在这里创建了一个 jsfiddle(我的第一个):http: //jsfiddle.net/DizzyHigh/Bpubu/4/
html:
<div id="left_container"></div>
<div class="container">
<a class="toggleMenu" href="#">Menu</a>
<ul class="nav">
<li class="test"> <a href="#">HOME</a>
</li>
<li> <a href="#">LOCATIONS</a>
<ul class="nav">
<li> <a href="#">Boroughs</a>
<ul class="nav">
<li> <a href="#">Enfield</a>
<ul>
<li><a href="#">E-Locations</a>
</li>
<li><a href="#">E-Unit Bases</a>
</li>
<li><a href="#">E-Parking</a>

CSS:
body, nav, ul, li, a {margin: 0; padding: 0;}
body {font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; }
a {text-decoration: none;}
.container {
width: 90%;
max-width: 900px;
margin: 10px auto;
}
.toggleMenu {
display: none;
background: #666;
padding: 10px 15px;
color: #fff;
}
.nav {
list-style: none;
*zoom: 1;
background:#175e4c;
}
.nav:before,
.nav:after {
content: " ";
display: table;
}
.nav:after {
clear: both;
}
.nav ul {

}
.nav a {
padding: 10px 15px;
color:#fff;
}
.nav li {
position: relative;
}
.nav > li {
float: left;
border-top: 1px solid #104336;
}

top: 0;
}
.nav li li a {
display: block;
background: #1d7a62;
position: relative;
z-index:100;
border-top: 1px solid #175e4c;
}
.nav li li li a {
background:#249578;
z-index:200;
border-top: 1px solid #1d7a62;
}
@media screen and (max-width: 768px) {
.active {
display: block;
}
.nav > li {
float: none;
}
.nav > li > .parent {
background-position: 95% 50%;
}
.nav li li .parent {
background-image: url("images/downArrow.png");
background-repeat: no-repeat;
background-position: 95% 50%;
}
.nav ul {
display: block;
width: 100%;
}
.nav > li.hover > ul , .nav li li.hover ul {
position: static;
}
}
JS:
$(document).ready(function() {
var ww = document.body.clientWidth;
$(".nav li a").each(function() {
if ($(this).next().length > 0) {
$(this).addClass("parent");
};
})
$(".toggleMenu").click(function(e) {
e.preventDefault();
$(this).toggleClass("active");
$(".nav").toggle();
});
adjustMenu();
var adjustMenu = function() {
if (ww < 768) {
$(".toggleMenu").css("display", "inline-block");
if (!$(".toggleMenu").hasClass("active")) {
$(".nav").hide();
} else {
$(".nav").show();
}
$(".nav li").unbind('mouseenter mouseleave');
$(".nav li a.parent").unbind('click').bind('click', function(e) {
// must be attached to anchor element to prevent bubbling
e.preventDefault();
$(this).parent("li").toggleClass("hover");
});
}
else if (ww >= 768) {
$(".toggleMenu").css("display", "none");
$(".nav").show();
$(".nav li").removeClass("hover");
$(".nav li a").unbind('click');
$(".nav li").unbind('mouseenter mouseleave').bind('mouseenter mouseleave', function() {
// must be attached to li so that mouseleave is not triggered when hover over submenu
$(this).toggleClass('hover');
});
}
}
$(window).bind('resize orientationchange', function() {
ww = document.body.clientWidth;
adjustMenu();
});
})
任何css大师都可以为我指明正确的方向吗?
