一、直接上代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
.wrapper {
width: 600px;
height: 350px;
border: 1px solid red;
position: relative;
}
/* 5张图片叠加到一块 */
.wrapper img {
width: 100%;
height: 100%;
position: absolute;
left: 0;
top: 0;
display: none;
}
.wrapper img:nth-of-type(1) {
display: block;
}
/* 小圆点 */
.btn {
width: 150px;
display: flex;
justify-content: space-around;
position: absolute;
left: 225px;
bottom: 10px;
z-index: 100
}
.btn span {
display: block;
width: 15px;
height: 15px;
border: 3px solid white;
border-radius: 50%;
}
/* 左右箭头 */
.wrapper a {
text-decoration: none;
font-size: 50px;
color: red;
position: absolute;
top: 35%;
}
.wrapper a:nth-of-type(1) {
left: 10px;
}
.wrapper a:nth-of-type(2) {
right: 10px;
}
.active {
background-color: red;
}
</style>
</head>
<body>
<div class="wrapper">
<div class="contain">

<div class="btn">

</div>
<a href="javascript:void(0);"><</a>
<a href="javascript:void(0);">></a>
</div>
<script src="js/jquery-3.6.0.js"></script>
<script>
var index=0;
// 点击上一张
$("a:first").click(function(){
prev_pic();
})
// 点击下一张
$("a:last").click(function(){
next_pic();
})
// 悬浮停止
$(".wrapper").mouseover(function(){
clearInterval(id);
});
$(".wrapper").mouseout(function(){
autoplay();
})
// 下一张
function next_pic(){
index++;
if(index>4){
index=0;
}
addStyle();
}
// 上一张
function prev_pic(){
index--;
if(index<0){
index=4;
}
addStyle();
}
// 控制图片显示隐藏,小圆点背景色
function addStyle(){
$("img").eq(index).fadeIn();
$("img").eq(index).siblings().fadeOut();
$("span").eq(index).addClass("active");
$("span").eq(index).siblings().removeClass("active");
}
// 自动轮播
var id;
autoplay();
function autoplay(){
id=setInterval(function(){
next_pic();
},1000)
}
</script>
</body>
</html>
