You could create a blank hidden form field and get the javascript to
populate its value before postback, e.g:

<form id="form1" runat="server">
<asp:HiddenField ID="HiddenField1" runat="server" />
<input type="submit" name="submit" value="GO" />
<br />
<asp:Literal ID="litResult" runat="server"></asp:Literal></form>
<script language="javascript" type="text/javascript">
<!--
document.form1.HiddenField1.value='Your value';
//-->
</script>

In the code behind file:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
If Page.IsPostBack = True Then
litResult.Text = HiddenField1.Value
End If
End Sub

Michael,

You can use one of the register script methods, there are more in the Page
class. Have a look at this.

I hope this helps,
