writing a javascript client-side shopping cart

[transkawa]

can someone instruct on how to find directions for writing a client side
shopping cart. i prefer writing mine than using google checkout or
whatever exists on the internet because of the peculiarities of the
region i am coming from.
will really appreciate any online references.

Further, alt.cljs does not exist (your newsgroups list is very much out
of date) and this has nothing to do with the Mozilla JavaScript Engine.

alt.comp.lang.javascript doesn't exist? Really?

It does exist and gets a small amount of traffic, the non-spam stuff I
usually refer back to here.

You really don't want to make it client side, for a vast number of
reasons.

1) Client side is far too easy to fake.

2) The only way to store data in a widest range of browsers is by
using cookies.[1]

3) Client side scripting may be disabled, in which case your cart is
totally useless.

4) Client side, with out some form of server side support, can't
email when the order is complete and ready to be processed.

[1] Yes, I know that newer browsers do have all sorts of nifty way to
store data locally, but I don't feel this has reached a usable level of
penetration yet.

It does not exist on well-maintained NetNews servers.

That traffic is only coming in as crossposts from the Google Groups
*archive* and not well-maintained NetNews servers.

OK, I'll admit I don't have the best understanding of things, and I am at
risk of going offtopic (but JS groups aught to be on topic in a JS group)

This is the header from the message as received in alt.cljs:

Path: s03-b19.iad!npeersf01.iad.highwinds-media.com!npeer03.iad.highwinds-

Now, looking at the Message-ID, it seems to have originated from an NNTP
server.

Wouldn't messages coming in from a google-groups cross post have a
different Message-ID number? Or a hint /somewhere/ that that message was
crossposted by google?

ISTM it must have originated from an NNTP server, or you could not read it.
("With the evolution of the Internet into mainstream use, the use of UUCP
for the exchange of electronic mail has been significantly reduced. Today,
UUCP is primarily used to link systems that are not on the Internet to a
nearby system that is connected." [UUCP2K])

Wouldn't messages coming in from a google-groups cross post have a
different Message-ID number?

Not necessarily. As you can see in my messages, the Message-ID can be set
by the client. And Google may synchronize with the NetNews server where the
message was injected or with one of its peers.

Or a hint /somewhere/ that that message was crossposted by google?

If the message was coming in from or via Google NetNews servers, you should
see it in the Path header field. That is not the case here.

But AISB, the list of servers still having alt.comp.lang.javascript includes
not well-maintained NetNews servers, which includes nntp.aioe.org, from
which that message originated (as you can see in the last component of the
Path header field value).

do not do such a mindless crosspost again.

It is carried by AIOE, Demon/Highwinds, and Eternal-september, at least.
That's all of the general servers that I use currently.

Kindly consult a mental health specialist, or a craniotomist.

It is in the nature of Usenet that a newsgroup may exist on one server but
not on another. The fact that neither of the mentioned news server observes
rmgroup Control messages (or missed this particular one) is not evidence
that the group still exists on the majority of news servers.

There is evidence that it does not exist there, though, and that nobody has
sent a newgroup Control message for it again: It is _not_ in the archived
checkgroups for 2010.
