使用JQuery实现图片轮播效果的实例(推荐)

【效果如图】

【原理简述】

这里大概说一下整个流程:

1,将除了第一张以外的图片全部隐藏,

2,获取第一张图片的alt信息显示在信息栏,并添加点击事件

3,为4个按钮添加点击侦听,点击相应的按钮,用fadeOut,fadeIn方法显示图片

4,设置setInterval,定时执行切换函数

【代码说明】

filter(":visible") :获取所有可见的元素

unbind():从匹配的元素中删除绑定的事件

siblings:取得一个包含匹配的元素集合中每一个元素的所有唯一同辈元素的元素集合

【程序源码】

首先引入JS文件:

  <script src="bootstrap/js/jquery-1.11.2.min.js"></script>
    <script src="bootstrap/js/bootstrap.min.js"></script>
    <link href="bootstrap/css/bootstrap.min.css" rel="external nofollow" rel="stylesheet" type="text/css"/>

HTML部分:

<div id="banner"> 
   <ul>
    <li class="on"><a href="">1</a></li>
    <li><a href="">2</a></li>
    <li><a href="">3</a></li>
    <li><a href="">4</a></li>
    <li><a href="">5</a></li>
    <li><a href="">6</a></li>
   </ul>
   <div id="banner_list">
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a1.jpg" width="280" height="160" /></a>
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a2.jpg" width="280" height="160" /></a>
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a3.jpg" width="280" height="160" /></a>
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a4.jpg" width="280" height="160" /></a>
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a5.jpg" width="280" height="160" /></a>
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" target="_self"><img src="img/a6.jpg" width="280" height="160" /></a>
   </div>
  </div>
