Read cookie & send results with form

[5sisters]

Hi,

I'm kind of a newbie so if this is an easy one i apologise...

I have some js script on a couple of my pages that I want to develop further. It sets a cookie which is a little list of free samples that browsers can create as they browse the site...

Based on the to-do-list found here...
http://javascript.internet.com/cookies/to-do-list.html

What I want this to do is work a bit like a shopping cart except that all the perl carts I looked at were over complicated in that they all ask for payment...

Anyway I can get the list to display on any page using..

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
ListToDoItems();
// End -->
</SCRIPT>

How do I get this to be automatically included in a form as a hidden field?
<input type="hidden" name="subject" value="??">

Is this possible??? All help welcome

Dave,

I have attached the js script. sorry for the ambiguity.

And I apologise if I ask silly questions, I'm not much of a js expert :)
.
To display the cookie in a page this works...
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
ListToDoItems();
// End -->
</SCRIPT>

So are you saying that all I have to do is put..

document.formName.hiddenFieldName.value = "ListToDoItems()";

Here is the js on the head of the page


<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 1;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
var ShowCount = 0;
var SwapColour;
function ListToDoItems() {
var NumToDoItems = GetCookie('PT_NumToDoList');
var i;
var ToDoItem;
if (NumToDoItems == null) {
NumToDoItems = 0;
}
ShowCount = 0; SwapColour = 0;
for (i=1; i <= NumToDoItems; i++) {
ToDoItem = GetCookie('PT_ToDoItem'+i);
if (ToDoItem != null) {
PrintItem(ToDoItem, i);
}
}
}
function DeleteItem(Count) {

Thanks, I'll give that a try...

One more silly question...

do I still have to put the field
<input type="hidden" name="fieldname">
in the form

??
