Solution 1

The Best thing would be, view the source(html) before you register the script(comment it if you can) and see if you see any element name like txtIdentifierXml.

If your form has a name, then you can use it directly as:
<form name="myform" ...
then you can use:

JavaScript

document.myform.txtIdentifierXml

A your item is hidden you need little more tricky stuff there, ie to use clientID

document.getElementById('<%=txtIdentifierXml.ClientID %>').value

VB

Me.RegisterClientScriptBlock("CloseMe_2", "<script language="'javascript'">" & _
"var hidVal =document.yourformname.getElementById('<%=txtIdentifierXml.ClientID %>').value;" & _                    
"alert(hidVal);" & _
" window.returnValue = hidVal;" & _
" </script>")

open your page and see source before you register your script. And see if you can find exactly the same element : txtIdentifierXml

Member 7932936 6-Sep-12 1:19am

my page has only one txtIdentifierXml element

hidden filed is on server side you neeed to get client id of the filed to get the value in your javascript; solution updated.
