RE: Static Forms and the refresh button -- WEB400

Justin,

I must be missing something here -
They fill out a form, send data, you send back html
saying here is the number,
how can refresh have any data to send again, don't you
send an empty form back???

hmm, ok, you would really want to show them who they are - so,
how about this... yes javascript will be involved....

You send back an empty form (thus eliminating a refresh button doing
anything)   In the html code is javascript which creates a
"pop-up" window (no header, refresh, forward, back, not even a close (x)
button on the window)
and this shows the data along with the account number - you could even
post the window for a set amount of time (say 30 seconds)

I have done similar things here (javascript and auto timeout)
if you need some examples.

HTH

Mark

Good Morning,
            Here is the scenario.I have a static form that has about 12
fields in it. This form submits the data to a CGI program I have called
NEWCUSTSET.  This program accepts the customer's first name, last name,
address, etc.to create a new customer account. The NEWCUSTSET program
sends back a response web page saying that the customer account has been
created successfully. In the CGI program I calculate a new account
number for the customer. If you hit the refresh button on the web
browser (IE6.0), on the response page, it will resend the data to the
program thus using the same information to create a new account and
assigning it a new account number. So a customer service rep could sit
there a hit and keep hitting the refresh button  creating a thousand
accounts with the same user information. Awhile back I asked this same
question and received an answer to create a form with a "Random ID
Number". Well I thought about how to use this and realized that you are
still in the same predicament. Let's say instead of a static form page I
use a CGI program (NEWFORM) to display the form page with a Random Id
number. When the all information is entered into the form, it will be
sent to the NEWCUSTSET program. The NEWCUSTSET program will read the
information from the data stream, write it to the customer file, and
create a response web page. Well if I refresh the response web page I
still have the same data in the data stream. There is really nothing
that I can do if I generate a Random ID. I think the approach we need to
take to this is to find some JavaScript to disable the Refresh
capability on the response page. Any suggestions??????
