子頁面C#后臺代碼：
代碼如下:
/// <summary>  
     /// 將設置好的值賦給父頁面  
     /// </summary>  
     /// <param name="count">需要傳遞的值</param>  
     void SetValueToParentPage(int count, string strPersons) 
     { 
         StringBuilder jsStr = new StringBuilder(); 
         jsStr.Append(" var retValue = new Object();"); 
         if (count == 0) 
         { 
             jsStr.AppendFormat("retValue = null;"); 
         } 
         else 
         { 
             jsStr.AppendFormat("retValue.Nums='{0}';", count); 
             jsStr.AppendFormat("retValue.Names='{0}';", strPersons); 
         } 
         jsStr.Append("window.returnValue = retValue;window.close();"); 

         ClientScript.RegisterStartupScript(GetType(), "close", jsStr.ToString(), true); 
     } 

父頁面前臺js：
代碼如下:
function OpenPerChoose(url) { 
          var openobj = window; 
          if (typeof (window.dialogArguments) == "object") { 
              openobj = window.dialogArguments; 
          } 
          var returnValue = showPopWin(url, 800, 600, openobj); 
          if (returnValue != null) { 
              document.getElementById("<%=txtQualifiedNums.ClientID %>").value = returnValue.Nums; 
          } 
      } 

代碼如下:
//彈出窗口  
function showPopWin(url, width, height, returnFunc) { 
    width = parseInt(width) + 30; 
    height = parseInt(height) + 30; 
    return window.showModalDialog(url + "&Datetime=" + GetTime(), document, "dialogWidth:" + width + "px;dialogHeight:" + height + "px;help:0;status:0;scroll:auto;center:1;resizable:1;"); 
}
