for each loop javascript output ASP

I have a for each loop in javascript, of which I need to output to an
ASP array. unfortunantly not too familiar with javascript..

the loop is for items ordered in a shopping cart. they are displayed
as rows of a table. all i need to do is get the same data into an ASP
array to use on the next page, specificaly the +theitem+ and
+thenumber+ variables.

i can pass any one variable like this:
document.writeln('<INPUT TYPE="hidden" NAME="itemName"
VALUE="'+theitem+'" SIZE="40">');

but need a way to get them all. thanks for any help!

the javascript loop:

for (var i = 0; i <= fulllist.length; i++) {
if (fulllist.substring(i,i+1) == '[') {
thisitem = 1;
itemstart = i+1;
} else if (fulllist.substring(i,i+1) == ']') {
itemend = i;
thequantity = fulllist.substring(itemstart, itemend);
itemtotal = 0;
itemtotal = (eval(theprice*thequantity));
temptotal = itemtotal * 100;
subtotal = subtotal + itemtotal;
weighttotal = 0;
weighttotal = (eval(theweight*thequantity));
subweight = subweight + weighttotal;
itemlist=itemlist+1;
document.write('<tr><td>'+thequantity+'</td>');
document.writeln('<td>'+thenumber+'</td><td>
'+theitem+'</td><td>'+theprice+'</td><td>'+alterError(itemtotal)+'</td></tr>');

} else if (fulllist.substring(i,i+1) == '|') {
if (thisitem==1) theitem = fulllist.substring(itemstart, i);
if (thisitem==2) theprice = fulllist.substring(itemstart, i);
if (thisitem==3) thenumber = fulllist.substring(itemstart, i);
if (thisitem==4) theweight = fulllist.substring(itemstart, i);
thisitem++;
itemstart=i+1;
}
}

Your code is confusing, and I am not exactly sure what you are trying to
accomplish. When passing values between a Web page and the server, it
is often useful to do it in a single string, using a delimiter.

If your values do not have spaces, you can use spaces, such as: "item1
item2 item3" etc. If your values have spaces, pick a character that you
know is not allowed in your values, such as ~. Something like this
would work: "Item 1~Item 2~This is item 3~Item 4".

In javascript, if your values are in an array:

var x = new Array( "Item 1", "Item 2", "Item 3" );

You can join them as a string like this:

var y = x.join("~");

This will produce a string in y that looks like this: "Item 1~Item
2~Item 3"

In Javascript, if you have a string that is delimted, you can split it
into an array likewise like this:

var z = y.split("~");

This will create an array z that is identical to x.

So, with that, you know how to use arrays to make a string, and
vice-versa. You can do this to convert an array into a string, and put
it in your hidden value. You can do this in Javascript, if you have a
value that is like this:

<INPUT TYPE=hidden NAME="itemName" VALUE="" ID="myHidden">
<SCRIPT type="text/javascript>
document.getElementById("myHidden").value = x.join("~");
</SCRIPT>

Assuming x is an array that you want to send to your ASP page.

Then, on your ASP page, I know that VBScript has a the same join/split
functionality. ASP/VBScript is out of the realm of this group.

Good luck,
Brian

Bunnyman, you can't get there from here. Javascript is a client-wide
technology, ASP is server side. The only way to pass your values to an asp
page is through a querystring:

document.location="mypage.asp?item1=shirt&item2=so cks&item3=shoes"

or through a form:

<form action="mypage.asp" method="get">
<input type=hidden name=item1 value="shirt">
<input type=hidden name=item2 value="socks">
<input type=hidden name=item3 value="shoes">
</form>

Once either happens, you can then process the values any way you like.
