Running a JavaScript function server-side

[David C. Holley]

How would I run a JavaScript function in a *.asp page and then pass the
value returned to VBScript for further processing? ***Converting the
function to VBScript is *NOT* an option.

A *client-side* JavaScript function? You can't do that in a single load of
an ASP page. You would have to submit a form or redirect or something along
those lines. Here is the order of operations:

(a) browser requests ASP page

(b) server-side code runs

(c) client-side code runs (at this point, there is nothing left but HTML; no
server-side functions, no access to server-side databases, no ability to set
session variables, etc)

See http://www.aspfaq.com/2281 for some workarounds (this revolves around
setting session variables, but you could use it to do any further
server-side processing). Note that anything you do on the server (e.g. set
a session variable) is not available until you request another ASP page,
because of the order of operations described above. The current ASP page
simply does not contain any ASP by the time an end user can interact with
the client-side script.

Let me restate that...

I seem to recall seeing that a *.asp can execute JavaScript. If I'm not
mistaken.

Create a server-side javascript script block in which you place your
javascript function. then call the function from your server-side vbscript
script block.

There is an article at www.aspfaq.com about doing this, but I don't have
time to search for it right now, so I suggest you do so.

You're not mistaken: ASP supports both vbscript and
jscript/javasctipt/ECMAscript

I was thinking of the first one, but the other one is good too.
