Add javascript at bottom of a page?

Brian Bischof

I'm trying to add javascript to a page so that it gets executed when the
page opens. I also need to do this during runtime b/c the javascript will
change each time.

In MSDN I saw that you can make the <Body> tag a server side object and then
add an attribute to it. Example:
<Body Id="Body1" runat="server">
in VB.NET
Body1.Attribute s.Add(...)

However, this doesn't work for me. When I attempt to make the <Body> tag a
server side control, this is ignored. When I look at the .aspx.vb code I see
that the Body object is never added to the code. I tried declaring it
manually but still didn't work.

I later found out in MSDN that there is a method called
RegisterStartup Script that I can call. For example

Me. RegisterStartup Script("startup ", startupscript)

But when I do Intellisense there is no such method listed. It also says
there there is a method called RegisterClientS cript, but again this doesn't
appear in my intellisense. In fact, in Help it says that there are many
"Registerxx x" methods of the Page object and my Intellisense doesn't show
any of them. So I must be missing something obvious. I tried referencing the
object "Me" as well as "Page" but neither one has these methods.

I'm running out of ideas! This sounds like it is easy according to MSDN, but
none of the methods it recommends work for my app. Please help.

Hello Brian,

If you're in VB, make sure that you have the option checked that shows you *ALL* the members in the Intellisense (something like List Advanced Members). It's on the VB property page.

Yes, this is one of those areas where .NET becomes farcical.

RegisterStartup Script that I can call. For example

I think the method is actually a member of the "Page" class, so your
"Me" prefix would have to be pointing to a page object for it it work.

I don't use VB so I don't know much about "Me", but here is the full VB
code example from MSDN:

LOOK OUT FOR LINE WRAP!

[Visual Basic]
<html>
<head>
<script language="VB" runat="server">
public Sub Page_Load(Sende r As Object,e As EventArgs)
' Form the script to be registered at client side.
Dim scriptString As String = "<script language=JavaSc ript>
function DoClick() {"
scriptString += "showMessage2.i nnerHTML='<h4>W elcome to
Microsoft .NET!</h4>'}"
scriptString += "function Page_Load(){ showMessage1.in nerHTML="
scriptString += "'<h4>RegisterS tartupScript Example</h4>'}<"
scriptString += "/"
scriptString += "script>"

If(Not Me.IsStartupScr iptRegistered(" Startup")) Then
Me.RegisterStar tupScript("Star tup", scriptString)
End If
End Sub
</script>
</head>
<body topmargin="20" leftmargin="10" onload="Page_Lo ad()">
<form id="myForm" runat="server">
<span id="showMessage 1"></span>
<br>
<input type="button" value="ClickMe" onclick="DoClic k()">
<br>
<span id="showMessage 2"></span>
</form>
</body>
</html>

Telnet emulation with Javascript/dhtml

Does anyone have code they could share that would implement a telnet session in a browser using Javascript? I've seen it done once, but they did not have code available. This would be integral to preserving some old telnet-based software but allowing us to move on with web-only code at this point. Thank you in advance to anyone who can assist. (Ideally, it should be cross-browser, of course).
