我想做一个FLASH 焦点图实现最新的新闻首页图片显示

在网上下载了个FLASH 焦点图但在页面了有这样的

<script type="text/javascript">
imgUrl1="images/01.jpg";
imgtext1="蔬菜广告创意01"
imgLink1=escape("http://www.makewing.com");
imgUrl2="images/02.jpg";
imgtext2="蔬菜广告创意02"
imgLink2=escape("http://www.makewing.com");
imgUrl3="images/03.jpg";
imgtext3="蔬菜广告创意03"
imgLink3=escape("http://www.makewing.com");
imgUrl4="images/04.jpg";
imgtext4="蔬菜广告创意04"
imgLink4=escape("http://www.makewing.com");
imgUrl5="images/05.jpg";
imgtext5="蔬菜广告创意05"
imgLink5=escape("http://www.makewing.com"
);

---- 我想实现由数据库中读取这些具体代码怎么写，或是谁有更好的实现方法，希望具体点-----
谢谢大家

List<FlashNewsInfo> flashNewsList是从数据库取出来的，你可以用DataTable来实现这个。

得到这段代码之后你在页面中可以这么写：

<script language='javascript'>

<%=GetFlashNews()%>

</script>

    public static string GetFlashNews(List<FlashNewsInfo> flashNewsList, int focuswWidth, int focusHeight,int textHeight)

    {

        StringBuilder text = new StringBuilder(2048);

        int count=flashNewsList.Count;

        text.Append("<a target=\"_self\" href=\"javascript:goUrl()\">\n");

        text.Append("<script type=\"text/javascript\">\n");

        if (flashNewsList != null && flashNewsList.Count > 1)//有flash新闻信息

        {

            StringBuilder links = new StringBuilder(1024);//链接地址

            StringBuilder urls = new StringBuilder(1024);//图片url

            StringBuilder texts = new StringBuilder(1024);//标题文字

            links.AppendFormat("escape(\"NewsRead.aspx?CatalogId={0}&refId={1}\")", flashNewsList[0].CatalogId, flashNewsList[0].NewsId);
