实现效果如下:
话不多说直接上代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
a{
text-decoration: none;
color: black;
}
#menu{
width: 100%;
height: 20px;
background: gainsboro;
}
ul li{
list-style: none;
float: left;
padding-left: 20px;
background-color: whitesmoke;
}
.active {
color: white;
background-color: black;
}
.none {
background-color: whitesmoke;
}
</style>
</head>
<body>
<ul id="menu">
<li><a href="#">首页</a></li>
<li><a href="#">直播</a></li>
<li><a href="#">新闻</a></li>
<li><a href="#">关于</a></li>
</ul>
<script src="../JQuery/js/jquery-3.0.0.min.js"></script>
<script>
$('#menu li a').click(function () {
var f = this;
$('#menu li a').each(function () {
this.className = this == f ? 'active' : 'none'
});
});
</script>
</body>
</html>
