.NET中利用js让子窗体向父页面传值的实现方法

子页面C#后台代码：
复制代码代码如下:
/// <summary>
     /// 将设置好的值赋给父页面
     /// </summary>
     /// <param name="count">需要传递的值</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);
     }

父页面前台js：
复制代码代码如下:
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;
          }
      }

复制代码代码如下:
//弹出窗口
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;");
}

<th style="width: 100px;">
                培训合格人数：
            </th>
            <td style="width: 50px;">
                <asp:TextBox ID="txtQualifiedNums" runat="server" Width="50px" ReadOnly="true"></asp:TextBox>
            </td>
