急,和javascript相关,有源码,帮忙测试一下!!!

//1.建立c.htm

<%@ Page language="c#" Codebehind="$FILENAME$.cs" AutoEventWireup="false" Inherits="$INHERITS$" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head>
<title>test</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name=vs_defaultClientScript content="JavaScript">
<meta name=vs_targetSchema content="http://schemas.microsoft.com/intellisense/ie5">
<script defer>
<!--
function test()
{
var sScript="<script defer>function go2(){ alert('Hello from inserted script.') };go2();</script>";
document.frames["oIfrm"].document.body.insertAdjacentText("afterBegin",sScript);
//document.frames["oIfrm"].document.body.insertAdjacentHTML("afterBegin",sScript);
}
//-->
</script>
</head>
<body MS_POSITIONING="GridLayout" onload="test()">
<form id="form1" method="post" runat="server">
<iframe id="oIfrm" src="test.htm" frameborder="yes" width="100%" height="100%" runat="server"></iframe>
</form>
</body>
</html>

//2.建立test.htm

<%@ Page language="c#" Codebehind="$FILENAME$.cs" AutoEventWireup="false" Inherits="$INHERITS$" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<html>
<head>
<title>test</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name=vs_defaultClientScript content="JavaScript">
<meta name=vs_targetSchema content="http://schemas.microsoft.com/intellisense/ie5">
</head>
<body MS_POSITIONING="GridLayout">

<form id="Form1" method="post" runat="server">
sfasfs
</form>

</body>
</html>

之后,测试用insertAdjacentText它可以在test.htm正确显示,但改用insertAdjacentHTML它不执行?

大侠帮忙调试一下.
