                                </div>
<SCRIPT __designer:dtid="3377854339350821">
var speed3=1//速度数值越大速度越慢

}
}
var MyMar=setInterval(Marquee,speed3)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed3)}
</SCRIPT>
                                </div>
                        </td>
                    </tr>
                </table>
            </td>

</div>

 

 cs页的代码:

[csharp]

复制代码 代码如下:

dal_Collection dc = new dal_Collection();
Label1.Text = dc.GetIndexZouMaDeng();
 

dal_Collection.GetIndexZouMaDeng()的代码:


[csharp]
复制代码 代码如下:

using System.Text;

[csharp]

复制代码 代码如下:

public string GetIndexZouMaDeng()
    {

        StringBuilder res = new StringBuilder();
        DataTable dt0 = GetNewsPageDB("select top 10  CN_Id, CN_Title,CN_Intro,CN_Url,CN_Uid,CN_Times from Collection order by CN_Times desc");
        if (dt0.Rows.Count == 0)
        {
            res.Append("暂无相关数据!");
        }
        else
        {
            for (int i = 0; i < dt0.Rows.Count; i++)//参见【注释1】
            {
                res.Append("<td align=\"center\" height=\"139\" width=\"184\"><img height=\"135\" src=\"" + dt0.Rows[i][3].ToString().Substring(2) + "\" width=\"180\" /></td>");

            }
            if (dt0.Rows.Count <= 6)
            {
                res.Append(res.ToString());
            }
        }

        return res.ToString();
