Without further ado, I will just post the jquery code for you. The specific code is as follows:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="css/index.css"> <script src="js/jquery-1.11.3.js"></script> <script src="js/baner.js"></script> </head> <body> <div class="main"> <a href=""><img src="img/baner-1.jpg" alt=""></a> <a href=""><img src="img/baner-2.jpg" alt=""></a> <a href=""><img src="img/baner-3.jpg" alt=""></a> <a href=""><img src="img/baner-4.jpg" alt=""></a> <ul> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> </div> </body> </html> /*************初始化************/ *{margin:0;padding: 0;border: none;list-style: none} /*********轮播左右居中*************/ .main{ width: 1024px; height: 320px; margin: 0 auto; position: relative; } .main a{ position: absolute; } .main a img{ width: 100%; height: 320px; } /***********左边小图标************/ .main ul li.selected{ background: #f97157; } .main ul{ position: absolute; z-index: 999; top: 120px; left: 20px; } .main ul li{ width: 20px; height: 20px; border-radius: 50%; background: #909090; cursor: pointer; text-align: center; } /** * Created by Administrator on 16-3-12. */ /***********定义全局变量和定时器*************/ var t=null; var n=0;/**动态变化**/ var count; /************************/ $(function(){ count=$(".main a").length;/*给动态变化的n备用*/ /**让不是轮播中的第一个隐藏**/ $(".main a:not(:first-child)").hide(); /*点击当前li当前li对应的图片显示出来*/ $(".main ul li").click(function(){ var index=$(this).text()-1; n=index; console.log(n); /*****让当前显示的图片0.5S内渐隐,并匹配下一个渐显示*****/ $(".main a").filter(":visible").fadeOut(500).parent().children().eq(index).fadeIn(1000); /*******聚焦,给当前li追加类,改变背景色*******/ $(this).addClass("selected"); /****同时移除当前li的所有兄弟的类名为selected,还原背景色*****/ $(this).siblings().removeClass("selected"); }); /***定义定时器3秒执行一次****/ t=setInterval("autoMove()",3000); /****当鼠标进入时候定时器停止,移除时候定时器开启****/ $(".main").hover(function(){clearInterval(t)}, function(){t = setInterval("autoMove()", 3000);}); }); /***定义自动轮播函数****/ function autoMove(){ if(n>=(count-1)){ n=0; }else{ ++n; } /*****给li执行匹配的事件*****/ $(".main ul li").eq(n).trigger("click"); }
The above is the simple carousel effect implemented by Jquery introduced by the editor. I hope it will be helpful to everyone!
