Does anyone know of a way to set a vbscript variable equal to a javascript variable without reloading the page? I can't figure out how to do that...thanks in advance!

Maybe a little context would be nice...

What I would like to do is validate a code a user would enter through a form and display an alert box if the code isn't in my db, without submitting the form.

The lookup for code in db is not gona work in browser.
You have to submit the form to do the lookup on server side.
If you provide all codes to browser side, then is the user also able to lookup the code in the page source :-)

Thanks, that's great except for I'm going to be using some logic in the asp that connects to the database and I notice that because it's contained within the script tags like that it shows on when you view the source. I don't want even a procedure name or connection variable to be present for anyone to see. Thoughts?

thanks again

Sorry nevermind, I don't know what I was thinking that I could use a connection to the db that way...but that's good to know for future reference passing the variable around like that

I was just browsing through the solutions and saw this one, and thought I would comment on it.

There is actually a way. Have a hidden iframe:

<iframe style="display:none;" src=somepage.asp name=aspFrame></iframe>

The iframe should look something like this:

dim varName
if varName<>"" then
   response.write("<script>alert('The variable is called "+varName+"');</script>");
end if

<form action=somepage.asp method=post>
<input type=hidden name=fieldName>

And when you want to send the data, do this:

varName="Some value";

I haven't actually tested it but it should work.

That's an intersting technique, I'll have to play around with that as well. thanks
