需求：页面显示教师信息列表，列表中每一条数据显示图片滚动插件，每张图片的长宽及长宽比例各不相同。
前提条件：美工把静态页面写好
HTML代码：
@using Models;
@{
List<cms_content> teacherList = ViewData["teacherList"] as List<cms_content>; //春雨树频道
PagerModel pager = ViewData["pager"] as PagerModel;
}
<div class="teacherteam_box">
<h1>教师团队</h1>
@foreach (cms_content teacher in teacherList)
{
<div class="teacher_box">
<div class="teacher_img fl">
<img src="~/Theme/images/t1.png" />
</div>
<div class="teacher_infor fl">
<h2>@teacher.title</h2>
<p>
@teacher.description
</p>
<div class="products_box">
<div class="products_pre">
<img src="~/Theme/images/left.png" />
</div>
<div class="products_next">
<img src="~/Theme/images/right.png" />
</div>
<div class="div-imgbox">
<ul>
@foreach (Tuple<string, string> item in teacher.imgList)
{
<li>
<img alt="@item.Item1" src="@item.Item2" />
</li>
}
</ul>
</div>
</div>
</div>
<div class="clear"></div>
</div>
}
<div class="page_box">
<span>共@(pager.totalRows)条信息</span>
<a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" onclick="teacherPage(this,1)">首页</a>

if (flag == 2 && page > 1) { page = page - 1; }
if (flag == 3 && page < totalPage) { page = page + 1; }
if (flag == 4) { page = totalPage; }
$.ajax({
type: "GET",
url: "@Url.Content("~/")home/teachers?t=" + new Date().valueOf(),
data: { page: page },
success: function (data) {

//滚动图片
