Here is the scenario. I have an alert that fires if the user has not
filled in a field. What I would like to do is have the browser focus
on the message (div id="message"). That div is generated only if
there is an error, and the server side code is placed within the
head. What I think is happening is the js focus is firing BEFORE the
div is rendered, because I am getting the js error
document.getElementById("") is null or is not an object. This is not
something vital, just something I think would be nice for the user
(especially if the form and message are below the fold). I have
included code and markup below. (no URL - this is stripped down to
what's necessary).
<% option explicit%>
<!--#include file="docheader_inc.asp"-->
<%
dim fname, isget
if request.servervariables("REQUEST_METHOD") = "POST" then
ispost = true
elseif request.servervariables("REQUEST_METHOD") = "GET" then
isget = true
end if
if ispost then %>
if request.form("fname") = "" then
required = "fname"
message = "First name is required"
end if
if message <> "" then
%>
<script type="text/javascript">
alert("<%=message%>");
document.getElementById("message").focus()
</script>
<% message = "<div id=" & chr(034) & "message" & chr(034) &
"><strong>" & message & "</strong></div>"
end if
fname = "Your first name"
end if%>
