这篇文章主要为大家展示了"jquery如何实现轮播效果"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"jquery如何实现轮播效果"这篇文章吧。

jquery实现轮播效果的方法：1、通过jquery的hover()绑定鼠标上悬以及离开时的事件处理;2、 通过jquery的bind()方法绑定鼠标点击事件处理前后翻动即可。

本文操作环境：windows7系统、jquery-2.1.4版、DELL G3电脑

Jquery代码实现图片轮播效果

文章写的不好，还请各位高手指教，不废话了，先上张效果图吧看下：

首先是初始化部分：将除了第一张轮播图片意外的图片都隐藏，并且隐藏向前、向后按钮，使第一个索引按钮处于激活状态。

事件部分：通过jquery的hover()绑定鼠标上悬以及离开时的事件处理， jquery的bind()方法绑定鼠标点击事件处理向前、向后翻动、轮播控制：pre(), next(), play(), start()开始自动轮播，stop()停止自动轮播。

下篇是一个纯粹的jquery轮播插件， 该插件可以定制各种效果，方便的配置以及可扩展。

下面是整体的代码：

index.html[html] view plaincopy jquery轮播效果图 * { padding: 0px; margin: 0px; } a { text-decoration: none; } ul { list-style: outside none none; } .slider, .slider-panel img, .slider-extra { width: 650px; height: 413px; } .slider { text-align: center; margin: 30px auto; position: relative; } .slider-panel, .slider-nav, .slider-pre, .slider-next { position: absolute; z-index: 8; } .slider-panel { position: absolute; } .slider-panel img { border: none; } .slider-extra { position: relative; } .slider-nav { margin-left: -51px; position: absolute; left: 50%; bottom: 4px; } .slider-nav li { background: #3e3e3e; border-radius: 50%; color: #fff; cursor: pointer; margin: 0 2px; overflow: hidden; text-align: center; display: inline-block; height: 18px; line-height: 18px; width: 18px; } .slider-nav .slider-item-selected { background: blue; } .slider-page a{ background: rgba(0, 0, 0, 0.2); filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#33000000,endColorstr=#33000000); color: #fff; text-align: center; display: block; font-family: "simsun"; font-size: 22px; width: 28px; height: 62px; line-height: 62px; margin-top: -31px; position: absolute; top: 50%; } .slider-page a:HOVER { background: rgba(0, 0, 0, 0.4); filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#66000000,endColorstr=#66000000); } .slider-next { left: 100%; margin-left: -28px; } $(document).ready(function() { var length, currentIndex = 0, interval, hasStarted = false, //是否已经开始轮播 t = 3000; //轮播时间间隔 length = $('.slider-panel').length; //将除了第一张图片隐藏 $('.slider-panel:not(:first)').hide(); //将第一个slider-item设为激活状态 $('.slider-item:first').addClass('slider-item-selected'); //隐藏向前、向后翻按钮 $('.slider-page').hide(); //鼠标上悬时显示向前、向后翻按钮,停止滑动，鼠标离开时隐藏向前、向后翻按钮，开始滑动 $('.slider-panel, .slider-pre, .slider-next').hover(function() { stop(); $('.slider-page').show(); }, function() { $('.slider-page').hide(); start(); }); $('.slider-item').hover(function(e) { stop(); var preIndex = $(".slider-item").filter(".slider-item-selected").index(); currentIndex = $(this).index(); play(preIndex, currentIndex); }, function() { start(); }); $('.slider-pre').unbind('click'); $('.slider-pre').bind('click', function() { pre(); }); $('.slider-next').unbind('click'); $('.slider-next').bind('click', function() { next(); }); /** * 向前翻页 */ function pre() { var preIndex = currentIndex; currentIndex = (--currentIndex + length) % length; play(preIndex, currentIndex); } /** * 向后翻页 */ function next() { var preIndex = currentIndex; currentIndex = ++currentIndex % length; play(preIndex, currentIndex); } /** * 从preIndex页翻到currentIndex页 * preIndex 整数，翻页的起始页 * currentIndex 整数，翻到的那页 */ function play(preIndex, currentIndex) { $('.slider-panel').eq(preIndex).fadeOut(500) .parent().children().eq(currentIndex).fadeIn(1000); $('.slider-item').removeClass('slider-item-selected'); $('.slider-item').eq(currentIndex).addClass('slider-item-selected'); } /** * 开始轮播 */ function start() { if(!hasStarted) { hasStarted = true; interval = setInterval(next, t); } } /** * 停止轮播 */ function stop() { clearInterval(interval); hasStarted = false; } //开始轮播 start(); });
