用JS实现图片轮播效果代码（一）

⽤JS实现图⽚轮播效果代码（⼀）⼀.实现原理（1）将所有图⽚放在⼀个⽗容器div⾥⾯，通过display属性来设置图⽚的出现与隐藏；（2）轮播图分为⼿动轮播和⾃动轮播；⼿动轮播的重点是每次点击图⽚下⽅的⼩圆圈，获得它的索引号，并让与之对应索引号的图⽚显⽰，并且此时的⼩圆圈为⾼亮显⽰；⾃动轮播：利⽤定时器setInterval()，来每隔⼀定的时间来播放⼀次图⽚。

（3）所有的基础知识：dom操作，定时器，事件运⽤。

⼆.轮播图页⾯布局：<div id="content"> <div class="carousel-inner"> <div class="item "><img src="./img/lunbo1.jpg" alt="第⼀张图⽚"></div><div class="item"><img src="./img/lunbo2.jpg" alt="第⼆张图⽚"></div><div class="item"><img src="./img/lunbo3.jpg" alt="第三张图⽚"></div></div><ul class="carousel-indicators"><li id='pic1'>●</li><li id='pic2'>●</li><li id='pic3'>●</li></ul><a href="#" class="carousel-control prev"><span><</span></a><a href="#" class="carousel-control next"><span>></span></a></div>三.轮播图的css样式：#content{width: 100%;height:500px;position: relative;}.carousel-inner{position: relative;width: 100%;overflow: hidden;height:500px;}.carousel-inner>.item>img{display: block;line-height: 1;z-index: 1;}.carousel-indicators{position: absolute;bottom:10px;left:45%;z-index: 2;list-style-type: none;}.carousel-indicators li{display:inline-block;padding: 0 15px;font-size: 24px;color:#999;cursor: pointer;z-index: 2;}.active1{font-size: 28px;color:#fff;}.carousel-control{position: absolute;text-decoration:none;color: #999;font-weight: bold;opacity: .5;font-size: 40px;z-index: 3;}.carousel-control:hover{color:fff;text-decoration: none;opacity: .9;outline: none;font-size: 42px;}.prev{top: 30%;left:20px;}.next{top:30%;right: 20px;}四.轮播图的js实现代码：window.onload = function(){//轮播初始化var lunbo = document.getElementById('content');var imgs = lunbo.getElementsByTagName('img');var uls = lunbo.getElementsByTagName('ul');var lis = lunbo.getElementsByTagName('li');//初始状态下，⼀个圆圈为⾼亮模式lis[0].style.fontSize = '26px';lis[0].style.color = '#fff';//定义⼀个全局变量，⽤来进⾏⾃动轮播图⽚顺序的变化var pic_index = 1;//⾃动轮播.使⽤pic_time记录播放，可以随时使⽤clearInterval()清除掉。

js实现轮播图的完整代码

js实现轮播图的完整代码今天写⼀个完整的轮播图，⾸先它需要实现三个功能：1.⿏标放在⼩圆点上实现轮播2.点击焦点按钮实现轮播3.⽆缝⾃动轮播轮播图的原理：⼀系列的⼤⼩相等的图⽚平铺，利⽤CSS布局只显⽰⼀张图⽚，其余隐藏。

通过计算偏移量（封装⼀个动画函数）⾃动播放，或通过⼿动点击事件切换图⽚。

html布局：<div id="box" class="all"><div class="inner"> <ul><li><a href="#"><img src="images/18.jpg" width="550" height="320" alt=""></a></li><li><a href="#"><img src="images/19.jpg" width="550" height="320" alt=""></a></li><li><a href="#"><img src="images/14.jpg" width="550" height="320" alt=""></a></li><li><a href="#"><img src="images/17.jpg" width="550" height="320" alt=""></a></li></ul><ol> </ol></div><div class="focusD" id="arr"><span id="left">&lt</span><span id="right">&gt</span></div></div>css样式：* {margin: 0;padding: 0;}/*<--清除底部三像素距离-->*/img {vertical-align: top;}.all {width: 550px;height: 320px;margin: 100px auto;padding: 5px;border: 1px solid #ccc;position: relative;}.inner {position: relative;width: 550px;height: 320px;background-color: pink;overflow: hidden;}.inner ul {width: 1000%;list-style: none;position: absolute;top: 0;left: 0;}.inner ul li {float: left;}.focusD {position: absolute;left: 0;top: 50%;width: 550px;padding: 0 10px;height: 30px;box-sizing: border-box;display: none;}.inner ol {position: absolute;right: 30px;bottom: 10px;}.inner ol li {width: 15px;display: inline-block;height: 15px;margin: 0 3px;cursor: pointer;line-height: 15px;text-align: center;background-color: #fff;}/*当前的⾼亮的⼩圆点*/.inner ol .current {background-color: orange;color: #fff;}.focusD span {display: inline-block;width: 25px;font-size: 24px;height: 30px;color: #ccc;line-height: 30px;text-align: center;background: rgba(255, 255, 255, 0.3); cursor: pointer;}#left {float: left;}#right {float: right;}显⽰效果：js部分：接下来我们要写js 代码，⾸先我们先获取我们需要的所有元素。

js鼠标点击图片切换效果代码分享

js⿏标点击图⽚切换效果代码分享本⽂实例讲述了js⿏标点击图⽚切换效果。

分享给⼤家供⼤家参考。

具体如下：实现原理很简单，其实是多张图⽚叠加起来，点击图⽚后依次赋予图⽚⼀个class，使其看起来在表⾯⽽已，点击图⽚，可以实现图⽚的不断切换效果。

运⾏效果图：--------------------------------------⼩提⽰：浏览器中如果不能正常运⾏，可以尝试切换浏览模式。

JS实现自动轮播图效果（js案例）

JS实现⾃动轮播图效果（js案例）现在很多⽹站都有轮播图，这篇⽂章主要为⼤家详细介绍了js实现轮播图的完整代码及原理，需要的⼩伙伴可以参考⼀下。

1、轮播图主要功能：1、图⽚⾃动轮播（主图切换同时下⾯导航图⽚也会跟着变化）2、⿏标悬停的时候，图⽚轮播停⽌，⿏标离开后继续3、单击左右按钮切换图⽚4、⿏标移⼊后左右按钮出现，移出消失具体效果如下：⿏标移⼊：轮播图⽚数量、css样式等，⼩伙伴也可根据⾃⼰的需求做相应调整。

2、具体实现部分特别重要的是，在我们写任何动态效果之前，我们应该先把静态页⾯写出来，在考虑动态效果的实现。

基于jquery实现左右按钮点击的图片切换效果

基于jquery实现左右按钮点击的图⽚切换效果jQuery可以制作出与Flash媲美的动画效果，这点绝对⽏庸置疑，本⽂将通过实例演⽰⼀个左右按钮点击的图⽚切换效果。

⼀、最终效果⼆、功能分析1、需求分析点击左边pre按钮，显⽰前⾯三个图⽚，点击右边的next按钮，显⽰后⾯的⼀组（三个）图⽚。

初始化只显⽰next按钮，到最后⼀组只显⽰pre按钮，中间过程两按钮都显⽰。

2、html结构分析<div class="activity" id="activity-slide"><a href="javascript:void(0)" class="pg_left ps_pre"></a><a href="javascript:void(0)" class="pg_right ps_next" ></a><ul class="clearfix"><li><a href="javascript:;"><img src="images/activity01-1410.jpg"></a></li><li><a href="javascript:;"><img src="images/activity02-1410.jpg"></a></li><li><a href="javascript:;"><img src="images/activity03-1410.jpg"></a></li><li><a href="javascript:;"><img src="images/activity03-1410.jpg"></a></li><li><a href="javascript:;"><img src="images/activity02-1410.jpg"></a></li></ul></div>#activity-slide是整个幻灯的⼊⼝，后⾯会将其作为参数来调⽤幻灯功能。
