function Marquee() {
if (tab2.offsetWidth - tab.scrollLeft <= 0)
tab.scrollLeft -= tab1.offsetWidth
else {
tab.scrollLeft++;
}
}
var MyMar = setInterval(Marquee, speed);
tab.onmouseover = function () { clearInterval(MyMar) };
tab.onmouseout = function () { MyMar = setInterval(Marquee, speed) };

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Bind_Repeater1();
}
}
public void Bind_Repeater1()
{
DataTable dt = new DataTable();
DataColumn dc1 = new DataColumn("ID", Type.GetType("System.Int16"));
DataColumn dc2 = new DataColumn("Img", Type.GetType("System.String"));
dt.Columns.Add(dc1);
dt.Columns.Add(dc2);
DataRow dr = null;
for (int i = 1; i <= 6; i++)
{
dr = dt.NewRow();
dr["ID"] = i;
dr["Img"] = "Upload/Images/img_"+i.ToString()+".jpg";
dt.Rows.Add(dr);
}
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
滚动效果来源网上，嵌套Repeater，数据源直接用DataTable建了一个表，可以改成从数据库取数据。
