项目需要实现图片轮播的效果，没找到资料，自己上网找了一个物效，然后自己整合进sharepoint 2010，不说废话，下面是源码：
photoNewsUserControl.ascx
<div>
<% photo(); %>
<script type="text/javascript">
var pic_width = 420; //图ª?片?宽¨ª度¨¨ 420*280
var pic_height = 260; //图ª?片?高?度¨¨
var text_height = 30; //文?字Á?高?度¨¨
var swfpath = '/_layouts/images/flashFocus01.swf'; //swf文?件t路¡¤径?地Ì?址¡¤
var swf_height = pic_height + text_height;
var pics = "", links = "", texts = "";
for (var i = 0; i < 3; i++) {
pics = pics + ("|" + imag[i]);
links = links + ("|" + link[i]);
texts = texts + ("|" + text[i]);
}
pics = pics.substring(1);
links = links.substring(1);
texts = texts.substring(1);
document.write('<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="' + pic_width + '" height="' + swf_height + '">');
document.write('<param name="allowScriptAccess" value="sameDomain"><param name="movie" value="' + swfpath + '"><param name="quality" value="high"><param name="bgcolor" value="#E1F2FF">');
document.write('<param name="menu" value="false"><param name=wmode value="opaque">');
document.write('<param name="FlashVars" value="pics=' + pics + '&links=' + links + '&texts=' + texts + '&borderwidth=' + pic_width + '&borderheight=' + pic_height + '&textheight=' + text_height + '">');
document.write('<embed src="' + swfpath + '" wmode="opaque" FlashVars="pics=' + pics + '&links=' + links + '&texts=' + texts + '&borderwidth=' + pic_width + '&borderheight=' + pic_height + '&textheight=' + text_height + '" menu="false" bgcolor="#FFFFFF" quality="high" width="' + pic_width + '" height="' + pic_height + '" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />');
document.write('</object>');
</script>
</div>
photoNewsUserControl.ascx.cs
namespace SharePointProject.photoNews
{
public partial class photoNewsUserControl : UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
}
public void photo()
{
try
{
SPSite manageSite = null;
SPWeb manageWeb = null;
SPSecurity.RunWithElevatedPrivileges(delegate
{
using (manageSite = new SPSite(SPContext.Current.Site.ID))
{
using (manageWeb = manageSite.OpenWeb(manageSite.RootWeb.ID))
{
SPList list = manageWeb.GetList("Lists/List2");
SPQuery myQuery = new SPQuery();
myQuery.Query = "<Where><Contains><FieldRef Name='_x5185__x5bb9_' /><Value Type='Note'>img</Value></Contains></Where><OrderBy><FieldRef Name='Modified' Ascending='False' /></OrderBy>";
myQuery.RowLimit = 3;
SPListItemCollection spc = list.GetItems(myQuery);
DataTable dt = spc.GetDataTable();
if (dt.Rows.Count > 0)
{
string str = "";
for (int i = 0; i < dt.Rows.Count; i++)
{
string[] imag = new string[3];
string[] link = new string[3];
string[] text = new string[3];
imag[i] = getImgUrl(dt.Rows[i]["_x5185__x5bb9_"].ToString());
link[i] = "http://" + Request.Url.Authority + "/pages/listdetail.aspx?picid=" + dt.Rows[i]["ID"].ToString();
text[i] = dt.Rows[i]["title"].ToString().Length > 10 ? dt.Rows[i]["title"].ToString().Substring(0, 10) + "..." : dt.Rows[i]["title"].ToString();
str += "imag[" + i + "]='" + imag[i] + "';";
str += "link[" + i + "]='" + link[i] + "';";
str += "text[" + i + "]='" + text[i] + "';";
}
string abc = "<script language='javascript'>";
abc += "var imag=new Array();var link=new Array();var text=new Array();";
abc += str;
abc += "</script>";
Response.Write(abc);
}
}
}
});
}
catch { }
}
public string getImgUrl(string html)
{
string url = "";
Regex reg = new Regex(@"(?i)<img[^>]*?src=(['""]?)([^'""\s>]+)\1[^>]*>");
Match m = reg.Match(html);
if (m.Success)
{
if (m.Groups[2].Value.Contains("http"))
{
url = m.Groups[2].Value;
}
else
{
url = "http://" + Request.Url.Authority + m.Groups[2].Value;
}
}
return url;
}
}
}
效果如下：
说明 ：你输出的数组大小就是显示的图片数量
