1.swiper插件实现轮播图

swiper是一个实现轮播图很强大，上手也容易。并且也是现在app，网址等用的最多的，
官方网址：http://www.swiper.com.cn/
下载插件导入，按照教程即可实现精美效果

代码部分

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <link rel="stylesheet" type="text/css" href="swiper-3.4.1.min.css"> <script type="text/javascript" src="jquery/jquery-3.0.0.min.js"></script> <script type="text/javascript" src="swiper-3.4.1.jquery.min.js"></script> <style type="text/css"> .swiper-container{ width: 790px; height: 340px; } </style> </head> <!-- 结构以及class的类名不允许更改 --> <body> <div class="swiper-container"> <div class="swiper-wrapper"> <div class="swiper-slide">![]((1).jpg)</div> <div class="swiper-slide">![]((2).jpg)</div> <div class="swiper-slide">![]((3).jpg)</div> <div class="swiper-slide">![]((4).jpg)</div> <div class="swiper-slide">![]((5).jpg)</div> <div class="swiper-slide">![]((6).jpg)</div> <div class="swiper-slide">![]((7).jpg)</div> <div class="swiper-slide">![]((8).jpg)</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 type="text/javascript"> var mySwiper = new Swiper ('.swiper-container', { // 滚动方向 horizontal/vertical direction: 'horizontal', // 自动播放 autoplay:2000, // 是否循环播放 loop: true, // 如果需要分页器（小圆点） // 是否需要分页器 pagination: '.swiper-pagination', // 点击分页器是否切换到对应的图片 是 true 否 false paginationClickable:true, // 如果需要前进后退按钮 nextButton: '.swiper-button-next', prevButton: '.swiper-button-prev', // 用户操作swiper之后，是否禁止autoplay。默认为true：停止。 // 如果设置为false，用户操作swiper之后自动切换不会停止，每次都会重新启动autoplay。 // 操作包括触碰，拖动，点击pagination等。 autoplayDisableOnInteraction:false, }) </script> </body> </body> </html>

2.JS实现轮播图

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>轮播图</title> <style> #loopDiv{ width: 790px; height: 340px; margin: 0 auto; position: relative; } #list{ list-style: none; position: absolute; bottom: 10px; left: 250px; } #list li{ float: left; width: 20px; height: 20px; line-height: 20px; text-align: center; border-radius: 50%; background: #aaa; margin-right: 10px; } .chooseBut{ width: 50px; height: 80px; background-color: rgba(0,0,0,0.2); color: #fff; font-size: 30px; line-height: 80px; text-align: center; display: none; } #left{ position: absolute; left: 0px; top: 130px; } #right{ position: absolute; right: 0px; top: 130px; } </style> </head> <body> <div id="loopDiv"> ![](img/0.jpg) <ul id="list"> <li>1</li> <li>2</li> <li>3</li> <li>4</li> <li>5</li> <li>6</li> <li>7</li> <li>8</li> </ul> <div id="left" class="chooseBut"><</div> <div id="right" class="chooseBut">></div> </div> <script type="text/javascript"> var jsDivBox = document.getElementById("loopDiv"); //图片节点 var jsImg = document.getElementById("pic"); //左右按钮节点 var jsLeft = document.getElementById("left"); var jsRight = document.getElementById("right"); //获取所有的li var jsUl = document.getElementById("list"); var jsLis = jsUl.getElementsByTagName("li"); //让第一个小圆点变为红色 jsLis[0].style.backgroundColor = "red"; //显示当前的图片下标 var currentPage = 0; //启动定时器 var timer = setInterval(func, 1000); function func() { currentPage++; changePic(); } function changePic() { if (currentPage == 8) { currentPage = 0; } if (currentPage == -1) { currentPage = 7; } //更换图片 //"img/1.jpg" jsImg.src = "img/" + currentPage + ".jpg"; //将所有的小圆点颜色清空 for (var i = 0; i < jsLis.length; i++) { jsLis[i].style.backgroundColor = "#aaa"; } //改变对应小圆点为红色 jsLis[currentPage].style.backgroundColor = "red"; } //鼠标进入 jsDivBox.addEventListener("mouseover", func1, false); function func1() { //停止定时器 clearInterval(timer); //显示左右按钮 jsLeft.style.display = "block"; jsRight.style.display = "block"; } //鼠标移出 jsDivBox.addEventListener("mouseout", func2, false); function func2() { //重启定时器 timer = setInterval(func, 1000); //隐藏左右按钮 jsLeft.style.display = "none"; jsRight.style.display = "none"; } //点击左右按钮 jsLeft.addEventListener("click", func3, false); function func3() { currentPage--; changePic(); } jsLeft.onmouseover = function() { this.style.backgroundColor = "rgba(0,0,0,0.6)"; } jsLeft.onmouseout = function() { this.style.backgroundColor = "rgba(0,0,0,0.2)"; } jsRight.addEventListener("click", func4, false); function func4() { currentPage++; changePic(); } jsRight.onmouseover = function() { this.style.backgroundColor = "rgba(0,0,0,0.6)"; } jsRight.onmouseout = function() { this.style.backgroundColor = "rgba(0,0,0,0.2)"; } //进入小圆点 for (var j = 0; j < jsLis.length; j++) { jsLis[j].onmouseover = function() { currentPage = parseInt(this.innerHTML) - 1; changePic(); }; } </script> </body> </html>

3.jQuery实现轮播图

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style type="text/css"> .pic{ width: 790px; height: 340px; margin: 10px auto; position: relative; overflow: hidden; } .content{ width: 99999px; height: 340px; position: absolute; left: 0px; top: 0px; } .content img{ float: left; } .index{ position: absolute; left: 300px; bottom: 5px; width: 200px; height: 20px; list-style: none; } .index li{ width: 10px; height: 10px; border-radius: 50%; float: left; margin-left: 10px; background-color: rgba(100,100,100,0.3); } .left{ width: 30px; height:50px; background-color:rgba(100,100,100,0.5); position: absolute; left: 0px; top: 150px; line-height: 50px; text-align: center; font-size: 20px; color: #fff; display: none; } .right{ width: 30px; height:50px; background-color:rgba(100,100,100,0.5); position: absolute; right: 0px; top: 150px; line-height: 50px; text-align: center; font-size: 20px; color: #fff; display: none; } .index .first{ background-color: red; } </style> <script type="text/javascript" src="jquery/jquery-3.0.0.min.js"></script> </head> <body> <div class="pic"> <div class="content"> ![](img/(1).jpg) ![](img/(2).jpg) ![](img/(3).jpg) ![](img/(4).jpg) ![](img/(5).jpg) ![](img/(6).jpg) ![](img/(7).jpg) ![](img/(8).jpg) </div> <ul class="index"> <li class="first"></li> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> </ul> <div class="right">></div> <div class="left"><</div> </div> <script type="text/javascript"> $(function(){ //每个固定的时间移动图片 var timer = setInterval(picLoop,1000); var index = 0; function picLoop(){ index++; if (index==8) {index=0;} $(".content").animate({"left":-790*index},300); $("li").eq(index).css("background-color","red") .siblings().css("background-color","rgba(100,100,100,0.3)"); } //定时器的控制 $(".pic").hover(function(){ clearInterval(timer); $(".left").show(); $(".right").show(); },function(){ timer = setInterval(picLoop,1000); $(".left").hide(); $(".right").hide(); }) $("li").mouseover(function(){ $(this).css("background-color","red") .siblings().css("background-color","rgba(100,100,100,0.3)"); index = $(this).index(); $(".content").animate({"left":-790*index},300); }) $(".left").click(function(){ index--; if (index==-1) {index=7;} $(".content").animate({"left":-790*index},300); $("li").eq(index).css("background-color","red") .siblings().css("background-color","rgba(100,100,100,0.3)"); }) $(".right").click(function(){ index++; if (index==8) {index=0} $(".content").animate({"left":-790*index},300); $("li").eq(index).css("background-color","red") .siblings().css("background-color","rgba(100,100,100,0.3)"); }) }) </script> </body> </html>

4.css3实现轮播图

css3的轮播实用性差，但是也可以使用，但是可以锻炼我们的思维。

<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> * { margin:0; padding:0; } ul { list-style:none; } .loop{ position: relative; margin:30px auto; width:600px; height:300px; } #wrap { position:relative; width:600px; height:300px; border:1px solid #9cc5ef; overflow:hidden; } #slider { width:300%; height:100%; font:100px/400px Microsoft Yahei; text-align:center; color:#fff; margin-left:0; -webkit-animation:slide1 3s ease-out infinite; } #slider li { float:left; width:600px; height:100%; } #slider img{ width:600px; height:100%; } /*创建三种动画策略*/ @-webkit-keyframes slide1 { 0% { margin-left:0;} 23% { margin-left:0;} 33% { margin-left:-600px;} 56% { margin-left:-600px;} 66% { margin-left:-1200px;} 90% { margin-left:-1200px;} 100% {margin-left:0;} } @-webkit-keyframes slide2 { 0% { margin-left:-600px;} 23% { margin-left:-600px;} 33% { margin-left:-1200px;} 56% { margin-left:-1200px;} 66% { margin-left:0;} 90% { margin-left:0;} 100% {margin-left:-600px;} } @-webkit-keyframes slide3 { 0% { margin-left:-1200px;} 23% { margin-left:-1200px;} 33% { margin-left:0;} 56% { margin-left:0;} 66% { margin-left:-600px;} 90% { margin-left:-600px;} 100% {margin-left:-1200px;} } /*当我们点击对应按钮时显示对应的动画*/ #first:checked ~ #wrap #slider { -webkit-animation-name:slide1; } #second:checked ~ #wrap #slider { -webkit-animation-name:slide2; } #third:checked ~ #wrap #slider { -webkit-animation-name:slide3; } /*短暂地取消动画名称，模拟重启动画*/ #first:active ~ #wrap #slider { -webkit-animation-name:none; margin-left:0; } #second:active ~ #wrap #slider { -webkit-animation-name:none; margin-left:-600px; } #third:active ~ #wrap #slider { -webkit-animation-name:none; margin-left:-1200px; } #opts { width:600px; height:40px; margin:auto; color:#fff; text-align:center; font:16px/30px Microsoft Yahei; position: absolute; top: 260px; left: 250px; } #opts label { float:left; width:30px; height:30px; margin-right:10px; background:#cccccc; cursor:pointer; border-radius: 50%; } #opts label:hover { background:#405871; } /* 隐藏Input按钮*/ #first, #second, #third { display:none; } </style> </head> <body> <div class="loop"> <input type="radio" name="slider" id="first"> <input type="radio" name="slider" id="second"> <input type="radio" name="slider" id="third"> <div id="wrap"> <ul id="slider"> <li>![](img/0.jpg)</li> <li>![](img/1.jpg)</li> <li>![](img/2.jpg)</li> </ul> </div> <div id="opts"> <label for="first">1</label> <label for="second">2</label> <label for="third">3</label> </div> </div> </body> </html>

用jquery写的无缝左右滑动轮播图

这里的圆点的html代码是通过js实现的，全jquery实现无缝轮播
1、html代码
<div class="banner">
<ul class="imgs">
<li><a href="#"><img src="/img/pic1.jpg" alt="第1张图片"></a></li>
<li><a href="#"><img src="/img/pic2.jpg" alt="第2张图片"></a></li>
<li><a href="#"><img src="/img/pic3.jpg" alt="第3张图片"></a></li>
<li><a href="#"><img src="/img/pic4.jpg" alt="第4张图片"></a></li>
<li><a href="#"><img src="/img/pic5.jpg" alt="第5张图片"></a></li>
</ul>

<ul class="nums"></ul>

<div class="btns">
<span class="prev"><</span>
<span class="next">></span>
</div>
</div>

2、css代码
div.banner{
display:block;
position: relative;
margin:0 auto;
width:1200px;
height:535px;
margin-top:30px;
overflow: hidden;
z-index: 1;
}
.imgs{
position: absolute;
top: 0;
left: 0;
}
.des{
position: absolute;
bottom: 0;
left: 0;
z-index: -2;
background: #ccc;
}
.des li{
float: left;
width: 1200px;
}
.imgs li{
float: left;
}
.nums{
position: absolute;
bottom: 10px;width: 100%;
text-align: center;
font-size: 0;
}
.nums li{
width: 10px;
height: 10px;
background:rgba(0,0,0,0.5);
display: block;
border-radius: 100%;
display: inline-block;
margin: 0 5px;
cursor: pointer;
}
.btns{
display: none;
}
.btns span{
display: block;
width: 50px;
height: 100px;
background: rgba(0,0,0,0.6);
color: #fff;
font-size: 40px;
line-height: 100px;
text-align: center;
cursor:pointer;
}
.btns .prev{
position: absolute;
left: 0;
top: 50%;
margin-top: -50px;
}
.btns .next{
position: absolute;
right: 0;
top: 50%;
margin-top: -50px;
}
.nums .active{
background-color: #fff;
}
.hide{
display: none;
}

3、全部jquery-js代码

$(function(){
var i=0;
var timer=null;
for (var j = 0; j < $('.imgs li').length; j++) { //创建圆点
$('.nums').append('<li></li>')
}
$('.nums li').first().addClass('active'); //给第一个圆点添加样式
var firstimg=$('.imgs li').first().clone(); //复制第一张图片
$('.imgs').append(firstimg).width($('.imgs li').length*($('.imgs img').width()));
//第一张图片放到最后一张图片后，设置ul的宽度为图片张数*图片宽度
$('.des').width($('.imgs li').length*($('.imgs img').width()));
// 下一个按钮
$('.next').click(function(){
i++;
if (i==$('.imgs li').length) {
i=1; //这里不是i=0
$('.imgs').css({left:0}); //保证无缝轮播，设置left值
};
$('.imgs').stop().animate({left:-i*1200},300);
if (i==$('.imgs li').length-1) { //设置小圆点指示
$('.nums li').eq(0).addClass('active').siblings().removeClass('active');
$('.des li').eq(0).removeClass('hide').siblings().addClass('hide');
}else{
$('.nums li').eq(i).addClass('active').siblings().removeClass('active');
$('.des li').eq(i).removeClass('hide').siblings().addClass('hide');
}
})
// 上一个按钮
$('.prev').click(function(){
i--;
if (i==-1) {
i=$('.imgs li').length-2;
$('.imgs').css({left:-($('.imgs li').length-1)*1200});
}
$('.imgs').stop().animate({left:-i*1200},300);
$('.nums li').eq(i).addClass('active').siblings().removeClass('active');
$('.des li').eq(i).removeClass('hide').siblings().addClass('hide');
})
//设置按钮的显示和隐藏
$('.banner').hover(function(){
$('.btns').show();
},function(){
$('.btns').hide();
})
//鼠标划入圆点
$('.nums li').mouseover(function(){
var _index=$(this).index();
$('.imgs').stop().animate({left:-_index*1200},300);
$('.nums li').eq(_index).addClass('active').siblings().removeClass('active');
$('.des li').eq(_index).removeClass('hide').siblings().addClass('hide');
})
//定时器自动播放
timer=setInterval(function(){
i++;
if (i==$('.imgs li').length) {
i=1;
$('.imgs').css({left:0});
};
$('.imgs').stop().animate({left:-i*1200},300);
if (i==$('.img li').length-1) {
$('.nums li').eq(0).addClass('active').siblings().removeClass('active');
$('.des li').eq(0).removeClass('hide').siblings().addClass('hide');
}else{
$('.nums li').eq(i).addClass('active').siblings().removeClass('active');
$('.des li').eq(i).removeClass('hide').siblings().addClass('hide');
}
},3000)
//鼠标移入，暂停自动播放，移出，开始自动播放
$('.banner').hover(function(){
clearInterval(timer);
},function(){
timer=setInterval(function(){
i++;
if (i==$('.imgs li').length) {
i=1;
$('.imgs').css({left:0});
};
$('.imgs').stop().animate({left:-i*1200},300);
if (i==$('.img li').length-1) {
$('.nums li').eq(0).addClass('active').siblings().removeClass('active');
$('.des li').eq(0).removeClass('hide').siblings().addClass('hide');
}else{
$('.nums li').eq(i).addClass('active').siblings().removeClass('active');
$('.des li').eq(i).removeClass('hide').siblings().addClass('hide');
}
},3000)
})
})
