本文通过实例代码给大家讲解了jQuery实现下拉菜单效果,非常不错，具有参考借鉴价值，需要的朋友可以参考下
基本效果是这样的~~
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<style type="text/css">
{
margin: 0;
padding: 0;
}
ul {
list-style: none;
}
.wrap {
width: 330px;
height: 30px;
margin: 100px auto 0;
padding-left: 10px;
background-color: skyblue;
}
.wrap li {
background-color: skyblue;
}
.wrap > ul > li {
float: left;
margin-right: 10px;
position: relative;
}
.wrap a {
display: block;
height: 30px;
width: 100px;
text-decoration: none;
color: #000;
line-height: 30px;
text-align: center;
}
.wrap li ul {
position: absolute;
: 30px;
display: none;
}
</style>
<script src="http://apps.bdimg./libs/jquery/2.1.4/jquery.js"></script>
<script>
$(function () {
//获取所有li，添加移入事件
$(".wrap>ul>li").mouseenter(function () {
//设置内部的子元素ul slideDown
$(this).children("ul").s().slideDown(600);
});
//移出li时，让内部子元素slideUp
$(".wrap>ul>li").mouseleave(function () {
$(this).children("ul").s().slideUp(600);
});
//如果当前运动没有完毕，又添加了新的动画，这时新的动画需要等待当前动画执行完毕才会开始
//如果持续添加。一定会造成动画的积累，这种情况我们称为动画队列
});
</script>
</head>
