Using Arrays from Javascript

Hi all --

I am new to arrays and could use some help. Here is my situation: I
have a very basic order form that I am allowing users to fill out.
They can enter multiple products onto this form, so I have created a
simple Javascript function that allows the user to dynamically add
another row of text boxes for each item he or she would like to
order. I am submitting the form to another ASP page which I hope can
read the information from the form and send an email notification to
somebody else.

I have already built the emailing portion of this ASP script, but I've
been unable to read in the various form items. I'm guessing there is
something incompatible with either my Javascript or ASP. I have
included the important code snippets below and could use some
assistance.

Thanks in advance!

? This does not make sense.

Do this to show us what is coming from your form:
<%
for each key in request.form
response.write key & ": " & request.form(key) & "
"
next
%>

This just takes the contents of the Request items and puts them into an
array variable that has a single item.

eg.

myvar = Array("test")

creates an Array which has a single value at location 0.

" & vbCrLf

" & vbCrLf
> next

What does the output look like?

I'm guessing you need to use Split to break up a string into items based on
a delimiter.

eg.

myvar = Split("test1,test2",",")

will result in an array with 2 items, "test1" at location 0 and "test2" at
location 1.

However, you might find that this is already done for you if the data is
posted as fields with the same name. You can check this using the .Count
property, eg.

If Request.Form("pub").Count > 1 Then
'there are multiple items, which means they were posted all with the
same field name and have been automatically split up in the Request
collection
End If

Thanks for all your help guys... Bob, I tried what you said. Here's
what I got :

qty[]: qty1, qty2, qty3
pub[]: pub1, pub2, pub3
comments[]: com1, com2, com3
Submit: Submit

OK, so now you want to put these results into arrays? Basically, just do
what Daniel said:
pub = Split(Request.Form("pub[]"),",")
qty = Split(Request.Form("qty[]"),","")

Guys,

Thanks for your help. I've just about got it working the way I need.
My apologies if my questions were ridiculous -- I don't have much
experience with arrays.

One more question: The items being stored in my arrays need to be
emailed to somebody. I have the email script working properly, so
that's not the issue. The problem is that I'm storing the body text
(and formatting it) for that email message in a variable called
"Bodytext" and I can't seem to incorporate my arrays into that.
Obviously, I need to build some sort of loop that outputs everything,
and I can't just do a simple Response.Write because that doesn't work
for this purpose. Any suggestions for getting these arrays to work
with that variable?

I haven't a clue what you're trying to do, but I will hazard a guess
that the Join method may be what you are after:
