如何解决window.showmodaldialog跨域无法获得返回值的问题

跨域取值
一般的做法,要用aspx把数据采集到本地进行调用

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml;
using System.Net;
using System.IO;
using System.Text;
namespace NetCMS.Web
{
public partial class AjaxGeturl : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string url = string.Empty;
url = Request.QueryString["url"];
Response.Write(GetResStr(url, "utf-8"));
Response.End();
}
}
string GetResStr(string url, string Encod)
{
WebRequest WReq;
WebResponse WResp;
StreamReader sr;
WReq = WebRequest.Create(url);
WResp = WReq.GetResponse();
sr = new StreamReader(WResp.GetResponseStream(), Encoding.GetEncoding(Encod));
string retValue = sr.ReadToEnd();
sr.Close();
return retValue;
}
}

}
