模式窗体下弹出两次提示错误问题！急
此帖内容前两天发过，没有得到有效回答，开新帖提问。
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。
起始页为页面一TestPage.aspx
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。
[解决办法]
应该是``
ClientScript.RegisterStartupScript(this.GetType(), "submitOk ", "alert( '123 '); ",true);
这句会重复提交页面``
[解决办法]
启动脚本改成客户端脚本ClientScript.RegisterClientScriptBlock()?
[解决办法]
调试看看

怎么搞什么复杂嵌套页面 ....

很不幸的告诉你,我按照你贴出来的代码建了页面,只弹出一次对话框....
难道你在忽悠大家？？
