最近一直在出差中，由于以前政府网站项目中的一个图片幻灯不知道咋的不能用了，图片出不来，原先的方式是直接通过Adobe的插件实现的，检查了一下，没发现问题，后来干脆换了个js的，效果如下：
main.css文件内容如下：

focus.js文件内容如下：

上面aspx中的值来自后台cs文件
//图片链接新闻信息相关内容
public string[] imgUrl = new string[6];
public string[] imgText = new string[6];
public string[] imgLink = new string[6];
imgUrl = getFlashNewsImageUrl();
imgText = getFlashNewsImageText();
imgLink = getFlashNewsImageLink();
public string[] getFlashNewsImageUrl()
{
Data dt = new Data();
DataSet ds = dt.GetItemBytype();
string[] news = new string[ds.Tables[0].Rows.Count];
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
string Item_url = ds.Tables[0].Rows[i]["p_pic"].ToString();//图片新闻路径
news[i] = Item_url;
}
return news;
}
public string[] getFlashNewsImageText()
{
Data dt = new Data();
DataSet ds = dt.GetItemBytype();
string[] news = new string[ds.Tables[0].Rows.Count];
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
string newitem = ds.Tables[0].Rows[i]["p_name"].ToString();
if (newitem.Length > 20)
{
newitem = newitem.Substring(0, 16) + "...";
}
string Itemtitle = newitem;//图片新闻标题 itemtitle
news[i] = newitem;
}
return news;
}
public string[] getFlashNewsImageLink()
{
Data dt = new Data();
DataSet ds = dt.GetItemBytype();
string[] news = new string[ds.Tables[0].Rows.Count];
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)

}
PS：给大家推荐一个好的演示站点
