Set cookie in javascript and retrieve it in vbscript ??

[Colin Graham]

hi folks,

just wonder if this is possible or is there a better way of doing
this. i need to store values in cookies between two forms. the details
are added in a popup when this is closed the main form stores these
values in hidden fields. at this point xml is built up and submitted
to a biztalk server. if there is an error the page is refreshed and
the initial values i added via the popup are lost.

my idea was to store these as cookies and populate the main form that
way if there is an error. My popup uses the following to send details
back to main form. e.g.,
window.opener.document.all.Doors.value=form1.Doors.value;

i have only ever used the following to set cookies in vbscript
<input type="hidden" value="<%=Request.Cookies("Doors")%>"
name="Doors" >

how can i set and get cookies using purely javascript ??? any examples
greatly appreciated.

Thanks in advance.

Best way (IMO) is with session variables, that way if someone has cookies
turned off or JS turned off, it still works.

Not like this.
You'd have to set the cookie by calling a function somewhere, probably form
onsubmit. And you can't call javascript code in a value like you do here with
ASP.
There are cookie functions posted here all the time, so a quick Google of the
group should bring some up. If you can't find any, I have a very simplistic
cookie function set (check, set, and get, simple values, no domains) in my
useful section in Kaeli's Space (see my sig).

Not exactly.
If session cookies are also turned off,
every page is a new session,
without any session variables to start with.

Most servers I have worked with fall back to URL re-writing if session
cookies are disabled.
If yours does not, then you should have all sessions use URL re-writing for
precisely this reason.

i.e. from the weblogic docs:
Using URL Rewriting Instead of Cookies
In some situations, a browser or wireless device may not accept cookies,
which makes session tracking with cookies impossible. URL rewriting is a
solution to this situation that can be substituted automatically when
WebLogic Server detects that the browser does not accept cookies.

I have no idea what you are talking about.

Are you talking ASP, Kaeli?

Then why did you argue?

No, actually Weblogic (WSAD) is JSP.
But ASP (IIS) can do it too. As can Cold Fusion. I don't think Apache /
Tomcat can auto-detect, but I dunno for sure. I don't think NES (Iplanet)
can, either, but 6.0 had some nice changes, so maybe it can now.

Session variables != session cookie.

Session variables are used (implemented) by a web server, but generally
implemented by whatever server-side scripting language you're using.
This has nothing at all to do with javascript unless we're talking JScript
with .net or some such. The OP said he was open to other ideas, so I gave him
one.
For example, in my web app, I store the user's name in a session variable,
along with several user preferences. These are loaded from the DB when the
user logs in. They are not stored on the client. The client gets only a
session ID, which points to that data on the server so I don't have to query
the DB over and over. Then, I can do something like
<p>Welcome <%= sessionBean.getUserName() %></p>

This is neither here nor there, Kaeli.

If the server does not recognize the client session, the server can store
al it likes, but does not know which client connection and session the
stored data belong to.

So the server either needs a session cookie [a cookie that expires at the
closing of the browser, also named ram-cookie] or a session code has to be
sent as a form or query value with all pages.

Is it the latter you mean.

Yes, it does.
It uses the URL if it can't use cookies. As I said.

A strange way of describing URL.
I would call it the querystring.

Anyway, since my users want something from me,
I am not going to accomodate them.

If they switch off ram-cookies, they loose functionality.

If they buy a car,
they should know it does not run without petrol,
and I am not going to push it.

You don't work on e-commerce and B2B applications, do you?
