RE: [cgiapp] Javascript to set multiple form params

["Kleindenst, Fred" <suppressed>]

All,

In my CGI::App I have several submit buttons that allow the user to
edit/Delete/select one of records displayed in a long list.  Each of
these 'submit' buttons ultimately fires off a different RM.  I
accomplish this by firing off to a parent run mode usually called
something like "myList_proc".  myList_proc looks for the name/value of
the submit button which allows me to fire off to the ultimate RM
(myEdit_proc, or myDelete_proc).  Another way to handle this is to have
text links, which have URL arguments which contain the runmode and other
information.

Yea ...

Id like to know too. I'm now using a lot of very basic, compatible
JavaScript, because it seems to be the only way to do some things
without
bloating the CGI world. Here a couple of examples of how I use
JavaScript,
that if somebody would like to provide an alternate solution, I would
rather
not use:

1. I too have pages with hidden's inside forms. Some of the forms are
just
dummy forms used for passing params to another run-mode. For example, I
have
many different pages that derive data from MySQL and display data in a
grid-type fashion. On the page there may be a button to add a new
record,
and then two buttons for each record; one to delete the record and the
other
to delete the record. Each button calls a JavaScript function to set
hidden
params, prompt the user, submit the form, etc. The delete record button
submits the current form with params back to the current run-mode and
with a
ctrl param set to 'del' and I delete the record. The Add and Edit
buttons
submit to a different form (also changing the run-mode) with ctrl params
=
'add' and 'edit', respectively and I present a data entry or edit form
(each
having a differnet run-mode.) Then these forms submit back to the
previous
run-mode for SQL processing. It all works and works pretty well, but if
there's a BETTER way (there's always ANOTHER way,) I'd sure like to
know:
I've got a lot of development time wrapped up into the way I'm doing
things
now and I played around with more than a few others before deciding on
my
current methodology.

2. The other thing I'm using JavaScript for that I can't see doing
another
way (without embedding Perl,) is to create dynamic <select> boxes. Ala
Delphi, I use JavaScript to create a hashed datasources in the window
object
and attach the <select> boxes to a datasource. Then I can link or chain
together multiple <select> boxes to create record filters and other such
things that don't need the page to reload in order to refine the
<option>'s.
So again, if there's a better way, I'd sure like to know.

BTW, as an OT aside, I think we're getting close to a world where
JavaScript/Browser incompatibilities will be a thing of the past. Also,
I
remember during the rapid growth days of the WWW, many web sites
disclaimed
that you need a specific browser in order to use the site or some such
nonsense. I think for some applications (maybe very few), it's not such
a
terrible thing that a client needs a specific browser or version
thereof,
thereby forgoing all the idiotic browser/version checking madness. So,
JavaScript does seem to have a place and it certainly doesn't appear to
be
going away ... at least until browsers provide Perl interpreters to
handle
user events :)
