前端之各种情况下实现的轮播图
1.样式一
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<style type="text/css">
*{margin: 0;padding: 0;}
ul,ol{ list-style: none;}
.wrapper{
width: 580px;
height: 240px;
margin: 100px auto;
/*overflow: hidden;*/
position: relative;
}
.wrapper ul{
width: 100%;
height: 240px;
overflow: hidden;
}
ol{
position: absolute;
right: 0;
bottom: 10px;
width: 190px;
}
ol li{
float: left;
width: 20px;
height: 20px;
margin: 0 5px;
text-align: center;
border-radius: 50%;
cursor: pointer;
background-color: #abc;
}
ol li.current{
background-color: pink;
}
</style>
<script type="text/javascript" src="./jquery-3.3.1.js"></script>
<script type="text/javascript">
$(function () {
// 根据ol下li的索引号，匹配ul下相对应li的索引号
$(".wrapper ol li").mouseenter(function () {
$(this).addClass("current").siblings('li').removeClass("current");
console.log($(this).index());
$(".wrapper ul li").eq($(this).index()).stop().fadeIn("fast").siblings('li').stop().fadeOut();
});
});
</script>
</head>
<body>
<div class="wrapper">
<ul>
<li><img src="./1.jpg" alt=""/></li>
<li><img src="./2.jpg" alt=""/></li>
<li><img src="./3.jpg" alt=""/></li>
<li><img src="./4.jpg" alt=""/></li>
<li><img src="./5.jpg" alt=""/></li>
</ul>
<ol>
<li class="current">1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ol>
</div>
</body>
</html>
2.无缝轮播
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
*{
padding: 0;
margin: 0;
}
ul{
list-style: none;
}
.slider-list{
width: 580px;
overflow: hidden;
margin: 100px auto;
position: relative;
}
.slider-list .slider-wrapper{
height: 470px;
}
.slider-wrapper ul{
height: 100%;
position: relative;
}
.slider-wrapper ul li{
float: left;
width: 590px;
height: 470px;
}
.slider-wrapper ul li a{
display: block;
width: 100%;
height: 100%;
}
.focus-img{
width: 590px;
height: 470px;
}
button{
position: absolute;
width: 24px;
height: 40px;
top: 50%;
line-height: 40px;
text-align: center;
background-color: rgba(0,0,0,.2);
color: white;
font-size: 30px;
border: 0;
outline: none;
cursor: pointer;
z-index: 99;
}
button.next{
right: 0;
}
button.prev{
left: 0;
}
.slider-index{
position: absolute;
bottom: 10px;
left:250px;
z-index: 2;
}
.slider-index span{
display: inline-block;
width: 10px;
height: 10px;
border: 2px solid red;
border-radius: 50%;
}
.slider-index span.active{
background-color: orange;
}
</style>
</head>
<body>
<div class="slider-list">
<div class="slider-wrapper">
<ul>
</ul>
</div>
<button class="next">></button>
<button class="prev"><</button>
<div class="slider-index">
<span class="active"></span>
<span></span>
<span></span>
<span></span>
<span></span>
</div>
</div>
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script type="text/javascript">
$(function(){
// 1.获取本地图片数据 590*470
var imgArr = ['./5.jpg','./1.jpg','./2.jpg','./3.jpg','./4.jpg','./5.jpg','./1.jpg'];
// 获取图片的宽度

// 2.遍历数据 将图片添加到ul中
for(let i = 0;i < imgArr.length;i++){
$(`<li>
<a href="javascript:;">
<img src=${imgArr[i]} title=${i}>
</a>
</li>`).appendTo('.slider-wrapper ul').addClass('slider-item');
}
// 设置图片的类名

$("span").eq(count-1).addClass("active").siblings("span").removeClass("active");
}
}
// 给小圆圈添加点击事件
$('span').click(function(){
//自己的样式
$(this).addClass("active").siblings("span").removeClass("active");
count = $(this).index()+1;
$("ul").animate({"left":-count*imgWidth},200);
})
// setInterval(next,2000);
})
</script>
</body>
</html>
3.基于bootstrapt下的轮播图
<!DOCTYPE html>
<html lang="zh-CN">

4.基于swiper下的轮播图
<!DOCTYPE html>

<head>
<link rel="stylesheet" href="swiper-4.3.2/dist/css/swiper.min.css">
<style type="text/css">
img {

<div class="swiper-slide"><img src="./5.jpg" alt="..."></div>
</div>
<!-- 如果需要分页器 -->
<div class="swiper-pagination"></div>
<!-- 如果需要导航按钮 -->
<div class="swiper-button-prev"></div>
<div class="swiper-button-next"></div>
<!-- 如果需要滚动条 -->
<div class="swiper-scrollbar"></div>
</div>
<script src="swiper-4.3.2/dist/js/swiper.min.js"></script>
<script language="javascript">
var mySwiper = new Swiper('.swiper-container',{
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
on: {
slideChange: function(){
if(this.isBeginning){
this.navigation.$prevEl.css('display','none');
}else{
this.navigation.$prevEl.css('display','block');
}
},
},
})
</script>
</body>
