Jquery 实现图片轮换

我是靠谱客的博主无辜学姐，最近开发中收集的这篇文章主要介绍Jquery 实现图片轮换，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

网站首页没有一点动画怎么可以，我以前用过Flash As3做过图片切换，效果非常不错，可是麻烦，改变起来麻烦。一直都想自己做个图片切换效果，总认为比较麻烦，今天自己实践了一下，其实还比较简单。不过有个小问题，IE8不兼容模式下设置有透明效果的div 样式添加失效了，但是我用谷歌，IE8兼容测试都ok。

反正是给自己记录的，也不多话了，js没有与页面分离，也没有做出插件。一个网站要不了几个这种效果，先实现了再说吧。最后的效果还是很高大上的。

页面+JS代码

复制代码代码如下:

<script type="text/javascript">

        var picCurrent = 1;

        var picTotal = 8;

        var interval; //自动运行

        function picChange(current) {

            //停止当前动画

            if ($("#divImg").is(":animated")) { $("#divImg").stop(); }

            picCurrent = current;

            //为当前选择的设置样式

            $("#divLink").find("a").removeClass("picselect")

            $("#divLink").find("a[title='" + picCurrent + "']").addClass("picselect");

            //设置下面的图片说明

            var remark = "<a href="images/pic" + picCurrent + ".jpg">";

            switch (picCurrent) {

                case 1: remark += " 菊花〔拉丁学名：Dendranthema morifolium（Ramat. ）Tzvel.〕，常用chrysanthemum。菊花是菊科，菊属多年生草本... "; break;

                default: remark += picCurrent + "测试说明"; break;

            }

            remark += "</a>";

            $("#picremark").html(remark);

            //运行动画

            $("#divImg").animate({ left: -((picCurrent - 1) * 1000) + "px" }, "1000");

            return false;

        }

        //暂不需使用

        function PicPer() {

            if (picCurrent > 1) {

                picCurrent--;

            }

            else {

                picCurrent = picTotal;

            }

            picChange(picCurrent);

        }

        //下一张

        function PicNext() {

            if (picCurrent == picTotal) {

                picCurrent = 1

            }

            else {

                picCurrent++;

            }

            picChange(picCurrent);

        }

        //自动切换图片

        function PicRun(functionName) {

            picChange(1);

            interval = setInterval(PicNext, "3000");

        }

        $(document).ready(function () {

            PicRun();

        });

    </script>

css的实现

复制代码代码如下:

.picMain

{

    margin: auto;

    overflow: hidden;

    width: 1000px;

    height: 400px;

    position: relative;

}

.picimg

{

    width: 10000px;

    height: 400px;

    background-color: #000000;

    position: absolute;

    top: 0px;

}

.picRemark

{

    position: absolute;

    width: 500px;

    height: 50px;

    bottom: 0px;

    left: 0px;

    color: #FFFFFF;

    text-indent: 2em;

}

.picRemark a

{

    color: #FFFFFF;

    text-decoration: none;

}

.picRemark a:hover

{

    text-decoration: underline;

}

.picaction

{

    position: absolute;

    width: 1000px;

    height: 50px;

    background-color: #000000;

    filter: alpha(opacity=50);

    -moz-opacity: 0.5;

    opacity: 0.5;

    overflow: auto;

    bottom: 0px;

    left: 0px;

    text-align: right;

}

.picaction a

{

    border: 1px solid #C0C0C0;

    width: 30px;

    height: 30px;

    float: right;

    line-height: 30px;

    text-decoration: none;

    text-align: center;

    color: #FFFFFF;

    font-weight: bold;

    margin-top: 10px;

    display: block;

}

.pic

{

    width: 1000px;
