这篇文章主要为大家提供了多种JQuery循环滚动文字图片效果代码，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
自己模仿JQ插件的写法写了一个循环滚动列表插件，支持自定义上、下、左、右四个方向，支持平滑滚动或者间断滚动两种方式，都是通过参数设置。JQ里面有些重复的地方，暂时没想到更好的方法去精简。不过效果还是可以的，如下（效果图上传后都加速了，实际效果比这个要慢很多）：
html代码如下：
循环滚动列表
css样式如下：
@charset "utf-8"; /* 简单reset */ body, ul, li { margin: 0; padding: 0; } body { font: 14px/24px Microsoft YaHei; color: #333; } ul { list-style: none; } a { color: #333; outline: none; text-decoration: none; } a:hover { color: #2986dd; } img { border: none; } .clearfix:after { visibility: hidden; display: block; font-size: 0; content: " "; clear: both; height: 0; } .clear { display: block; clear: both; height: 0; font-size: 0; line-height: 0; content: "."; overflow: hidden; } .wrap { width: 900px; padding-top: 30px; margin: 0 auto; } .boxs { padding: 15px; margin: 0 auto 30px; background-color: #e4fbff; } .box01 { width: 870px; } .box02 { float: left; width: 400px; } .box03 { float: right; width: 400px; } .box04 { width: 720px; } /* 具体样式 ---------- */ /* 通用必需样式 */ /* PS：有些重要样式在js里先写好了，下面id容器、ul和li标签的样式比较重要 */ .autoBox { position: relative; margin: 0 auto; overflow: hidden; } .autoBox ul { position: absolute; list-style: none; z-index: 2; } /* 第一、四个列表 */ /* PS：左右滚动型列表需要css定义高度，li标签可以有margin值 */ #autoScroll01, #autoScroll04 { width: auto; height: 174px; } #autoScroll01 ul li, #autoScroll04 ul li { float: left; width: 128px; height: 168px; padding: 3px; margin: 0 5px; _display: inline; } #autoScroll01 li a, #autoScroll04 li a { display: block; padding: 3px; border: 1px solid #dbdbdb; box-shadow: 0 0 3px rgba(170, 223, 252, 0.5); } #autoScroll01 li a:hover, #autoScroll04 li a:hover { border-color: #71ddff; box-shadow: 0 0 3px rgba(77, 185, 245, .90); } #autoScroll01 li img, #autoScroll04 li img { display: block; width: 120px; height: 160px; } /* 第二、三个列表 */ /* PS：上下滚动型列表需要css定义宽度，li标签尽量不要设置margin值 */ #autoScroll02, #autoScroll03 { width: 100%; height: auto; } #autoScroll02 ul li { height: 30px; line-height: 30px; overflow: hidden; } #autoScroll03 ul li { height: 40px; line-height: 40px; overflow: hidden; } #autoScroll02 li a, #autoScroll03 li a { display: block; width: 100%; height: 24px; line-height: 24px; margin: 3px 0; text-overflow: ellipsis; white-space: nowrap; overflow: hidden; } #autoScroll03 li a { margin: 8px 0; }js代码如下：
