关于脚本JS的问题

现有Repeate绑定的数据
<div style="padding-top: 5px; margin-left: -1px; width: 99%">
        <ul id="box" style="margin-left: 20px; margin-top: 2px;">
            <asp:Repeater ID="rptNews" runat="server">
                <ItemTemplate>
                    <div class="index_news_more">
                        <%#convertNewType(Eval("Type").ToString())%><a href="News<%#Eval("NewsEventID") %>.html">
                            <%#Eval("ChineseTitle")%></a>
                    </div>
                </ItemTemplate>
            </asp:Repeater>
        </ul>
    </div>如何使它一条一条的切换  效果
