dbi and javascript

[john]

I have 2 major issues currently with javascript.

1. Doesnt anybody do any server side javascript anymore. I cant find
anything on the net about it. My major issue is with database connections
and queries. How do I set up a connection and send a quiery. any how-tos,
links, sample code, advice whatever.

2. i fave a form that is dynamicly creating elements and I am trying to
pass it to a server side script. How do I do this. The number of elements
will be different everytime. 1 field will be the same every time and that
will be the number of elements I am passing. so the url will look
something like this

a.html?number="+ number +"&element0="+ document.forms[0].elements
[0].value

or

a.html?number="+ number +"&element0="+ document.forms[0].elements
[0].value +"&element1="+ document.forms[0].elements[1].value

etc.

3. this.location.replace(send); I am trying to use this as a redirect,
why doesnt it work? I call it when the submit button on the form is hit
and the form figures out which elements have been chosen. any ideas

Sure, but it's most common as JScript with ASP.
The syntax is a little different, IIRC, from Netscape's server-side
javascript. Someone correct me if I'm wrong.
If you're using ASP, search for JScript instead of javascript for links
(Google).

The same way you always do. With GET or POST.

If you're "passing" it to a server-side script via the URL, simply
submit using GET instead of POST and you don't have to build a URL.

If for some odd reason you feel the need to replace, as you imply below,
loop through the form element array and build the url.
e = document.myFormName.elements;
l = e.length;
for (i=0; i<l; i++)
{
// e[i] is a form element with name and value - do something with
it
}

What doesn't it do that you think it should? "it doesnt work" is about
as descriptive as calling up your mechanic and telling him your car is
broken.

Jscript is the exact same thing as javascript except that it is produced
by microsoft. You know how it goes microsoft is to cheap to licence
anything so they make there own shitty version (which nobody uses because
of vb (which is another crappy language)). In then end microsoft realizes
that its language is no good then pays the licensing fee's. You can do
javascript with a runat="server" in the script heading and it does run on
iis. Im not even sure microsoft supports jscript anymore.

e = document.myFormName.elements;
l = e.length;
for (i=0; i<l; i++)
{
// e[i] is a form element with name and value - do something with
it
}

the reason I am replacing the url is because I am building a survay which
has about 300 elements. If the user chooses a radio button, the
information on that section is needed. If the user does not, then I do
not. So I was hoping to cut down on bandwidth use by only sending the
needed information instead of all 300+ elements. Now by what you are
saying if I recreat the url and pass it, I can get the information by
reading it like it was a form. So if I do not have a form on my page and
I pass 7 elements I can get the information with a document.forms
[0].elements[0].value. am I correct on this?

3. this.location.replace(send); I am trying to use this as a

Well basicaly it doesnt do the redirect. I hit submit and it seems to
pass over this line and just reload the page sending all of the elements.
Is there issues with submit that makes it have to reload or can I break
out of the form reload and redirect to where I want to go. Would it be a
better idea to lose this this.location.replace(send); and change the form
to say document.write("action=\""+ send +"\"");

Not correct. JScript is an implementation of ECMAScript for browsers,
just like Javascript
You know how it goes microsoft is to cheap to licence anything so
they make there own shitty version (which nobody uses because of vb
(which is another crappy language)).
Which is it? Jscript is the same as Javascript (which means that
plenty of people use it) or nobody uses it?
In then end microsoft realizes that its language is no good then

There is no licensing fee on Javascript/ECMAScript. Are you thinking
of Microsoft's Java implementation? Your story sounds more like it.
You can do javascript with a runat="server" in the script heading
and it does run on iis.
It runs in ASP, which typically runs on an IIS.
Im not even sure microsoft supports jscript anymore.
They definitly do. The newest version of JScript implements the
working draft of ECMA 262 version 4, which adds things like classes
and type declarations to ECMAScript. It is compiled to .net, and can
therefore be used in ASP.net.
So if I do not have a form on my page and I pass 7 elements I can
get the information with a document.forms [0].elements[0].value. am
I correct on this?
if "document.forms[0].elements[0]" is something that is executed on
the server, then probably. If there are no forms on the client, then
"document.forms" is empty.
Well basicaly it doesnt do the redirect. I hit submit and it seems to
pass over this line and just reload the page sending all of the elements.
Where is "this.location.replace(...)" called? Are you sure "this" refers
to the global/window object?

Try adding "return false" to the onsubmit handler (I assume it is called
from one).
Is there issues with submit that makes it have to reload or can I break
out of the form reload and redirect to where I want to go.
Generally, to prevent an action, you return false from the action event
handler.
Would it be a better idea to lose this this.location.replace(send);
and change the form to say document.write("action=\""+ send +"\"");

Most likely not. That would give you an almost empty document containing:
action=" ...value of send... "

No it isn't the same and when you want to find out how to do something
with it, a search for jscript will bring up a LOT more (useful) results
than server-side javascript.
Just because runat=server works in IIS doesn't mean people use it. They
use language=jscript at the top or <script language=jscript> and write
the script in jscript. So, searching for jscript will be much more
useful for you.
the reason I am replacing the url is because I am building a survay which
has about 300 elements. If the user chooses a radio button, the
information on that section is needed. If the user does not, then I do
not. So I was hoping to cut down on bandwidth use by only sending the
needed information instead of all 300+ elements.

It's just text in the URL. I was unaware that affected bandwidth all
that much. Have you done any testing? I'd love to know the results. My
apps are all for intranet apps that run on a T1, so it'd be useful for
me to know in case I ever do an internet application.
Now by what you are
saying if I recreat the url and pass it, I can get the information by
reading it like it was a form.
SERVER-SIDE.
If you do it client-side with javascript, you'd need to parse the URL.
So if I do not have a form on my page and
I pass 7 elements I can get the information with a document.forms
[0].elements[0].value. am I correct on this?
No.
If you had a radio button called myRadio...
myVar = Request.Form("myRadio")

(That's vbscript - check your language of choice for forms processing on
the server. It may be the same in jscript.)

document.forms is client-side AFAIK and is not defined if you don't have
a form.
You would build the URL client-side using document.forms, but you must
have a form.

Well basicaly it doesnt do the redirect. I hit submit and it seems to
pass over this line and just reload the page sending all of the elements.

A form with no action defined sends to the same page (so it looks like
it's refreshing). So...
<form name="f1" onSubmit="whatever();return false;">
(replace the whatever function with yours)
Return false stops the submission to itself.
