[Javascript] Draggable Layers

[Andrew Dunn]

Dreamweaver has a built in function to make a layer draggable, I don't
understand it, but it works none the less.

Since Jan 1998 Shop at ssistant has been on the market as an all javascript
shopping cart (all except submissions to a forms to email script and
interfaces to PSPs [Payment Service Providers])

Throughout that period we have supported browsers from version 3 onwards
(those that worked anyway <G>)

Soon I shall beta version MC4 which requires version 4+ browsers and
makes use of .js and .css files.

Since browsers are free, why have an old one? (and since new browsers
are buggy why have a new one?)

Netscape 6 is something of a poser. It could improve its rendering speed
by 300% even 500% and still be slow and certain things it just does not
do - but doesn't give errors. I doubt whether I shall be able to support
it.

We have well over 1,000 commercial sites using our software. The ones
that are "fit to print" are listed at http://www.hometown.co.uk

The software home site is http://www.shopassistant.net
The developers forum is http://groups.yahoo.com/group/sass_dev

I would never make drag and drop the only way to use the shopping
software. But our developers should understand that it is one of many
possibilities. Since entry of data to the basket involves calling a js
function in the top window you can design a wide varieity of interfaces
with enormous flexiblility. The simplest would be a a link, and the most
complicated I have heard of uses over 40 selects to specify options for
an automatic lathe system.

Some developers set their scope of browsers more narrowly than our code
does. That is up to them. It will be those that don't mind saying that
the site can only be viewed in xxxx that will be the first to use drag
and drop. Actually the first that I know of (with Shop at ssistant) were
developers of a Spice Girls site in 1998 using a java applet.

Hope this is of interest,

Rodney

     Thanks Rodney. I've been playing around with DHTML and was really
wondering
     about the future of it. It's fine to play around with this stuff
but are commercial
     sites actually using it? If not, why not?

     The only sites I've seen use it for some navigation stuff, pretty
cool but not
     "web site critical" like shopping cart functionality.

     How many sites do have alternatives for non compatible
browser/javascript users?

       I did some experiments in relation to my own Shopping system
       You can find discussion in the publicly readable messages in our
developers forum
       eg.
       http://groups.yahoo.com/group/sass_dev/message/781
       a message which references a protoype page at :
       http://www.aflyingstart.net/tests/ddvid4.htm

       The code for the page makes use of the "Dynamic Duo" .js files
developed by Dan
       Steinman
       This was something that someone here on the list put me on to.
       I should mention that the original site has been taken down and
later work is
       accessible (wth some perseverance in getting to know the way the
site works) at
       SourceForge. Log in page is at
https://sourceforge.net/account/first.php

use draggable layers?
              In particular I'm interested in seeing sites that use
these techniquesi n a shopping cart
         eg. maybe dragging a product in to a shopping cart.
