HTML에서는 드롭다운 메뉴 기능을 구현할 수 있다. 예제 코드를 통해 jQuery로 드롭다운 메뉴 효과를 구현하는 방법이 설명되어 있어 참고할 만한 내용이다. 모두를 도울 수 있습니다.
기본 효과는 이렇습니다~~
<!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;
top: 30px;
display: none;
}
</style>
<script src="http://apps.bdimg.com/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").stop().slideDown(600);
});
//移出li时，让内部子元素slideUp
$(".wrap>ul>li").mouseleave(function () {
$(this).children("ul").stop().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>
