windows.showModalDialog窗体中点击按钮弹出两次提示窗口错误！急
各位好：遇到一个棘手的问题，在打开的模式窗体中，点击服务器按钮控件，在按钮事件中写
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);弹出两次提示窗体！
不明白为何弹出两次，具体代码如下。
页面1：调用模式窗体的父窗体
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "TestPage.aspx.cs " Inherits= "htManage_TestPage "
%>
<head runat= "server ">
<title> 1 </title>
<script language= "javascript ">
function showErrMsg()
{
window.showModalDialog
( "TestPageFrame.aspx ", " ", "center=yes;dialogHeight=20;dialogWidth=20;resizable=yes;status=yes;scroll=yes;
help=no ");
}
</script>
</head>
<body>
<form id= "form1 " method= "post " runat= "server ">
<div>
<input onclick= "return showErrMsg(); " type= "button " value= "保 存 " id= "button2 " name= "btnSave " />
</form>
</body>
</html>
页面2：模式窗体的加载窗体
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "TestPageFrame.aspx.cs "
Inherits= "htManage_TestPageFrame " %>
<head >
<title> 2 </title>
<base target= "_self "> </base>
</head>
<frameset rows= "0,* ">
<frame src= "about:blank ">
<frame src= "TestPage2.aspx ">
</frameset>
</html>
页面3： 模式窗体
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "Testpage2.aspx.cs " Inherits= "htManage_Testpage2 "
%>
<head>
<title> 3 </title>
<base target= "_self "> </base>
<script language= "javascript ">
function showErrMsg()
{
window.showModalDialog
( "TestPage3.aspx ", " ", "center=yes;dialogHeight=20;dialogWidth=20;resizable=yes;status=yes;scroll=yes;help
=no ");
}
</script>
</head>
<body>
<form id= "form1 " runat= "server " method= "post ">
<div>
<asp:Button ID= "Button1 " runat= "server " OnClick= "Button1_Click " Text= "Button " />
<input type= "button " value= "关闭 " onclick= "window.close() ">
</div>
</form>
</body>
</html>
页面4：模式窗体的后台代码
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class htManage_Testpage2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);
}
}
在这里先谢过各位达人，不吝赐教。

有点乱...
[解决办法]
代码好像有些贴错了
[解决办法]
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);
这句改成
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "123 ",true);试下
[解决办法]
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);
这句改成
ClientScript.RegisterStartupScript(this.GetType(), "confirm ", "123 ",true);试下

更正：

我上面回答不对，
刚才你你代码试下，就出来一次呀，html哪里出错
[解决办法]
更正：
ClientScript.RegisterStartupScript（this.GetType(), "alert ", " <script> alert( '123 ') </script> ",true)

4。防止打开新窗口（如提交表单）：
<base target= "_self ">

是否应该用IsStartupScriptRegistered来避免重复注册脚本.
[解决办法]
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);
===============================================
Page.ClientScript.RegisterStartupScript(this.GetType(), " ", " <script> alert( '123 ') </script> ");
