Getting specific form data loaded into a function

[Sam Wuebben]

I've been trying to get the values of hidden fields from one of many
forms on a page to load into a function.

The test page is at: http;//www.mvldesign.com/test/item_pop.html

The 'Add to Cart" image needs to send that forms data to the function
seen in the head.

Firebird's javascript Console states that "form has no properties"

What am I doing wrong?

I've looked thru all the typical resources and haven't found the
answer. Any specifics or general suggestions would be helpful.

More info than you need.........

I decided to use a form to hold the product data because the site
owner wants to be able to change each products status nightly and he
uses DW3. I made the product status be a DW Library item so he only
needs to select the library item and replace it with the new status.
Product data is not affected or changed. Less chance that he could
break something.

He has over 1000 products and he wants to manage them all by hand. So
I need the form code to be as generic as possible and, hopefully, not
depend on targeting a specific form name. He could add products
himself using an HTML code snip that would be a generic properly
classed table cell with an image place holder, the form, hidden
fields and submit image. Then he only needs to change the image and
the hidden fields values to have a new product.

eventually, all he needs is to have the form data filled in on a form
on the page at his secure server. Nothing real fancy since he wants to
limit each online purchase to no more than three items. If some one
cares to suggest another non-database driven way of doing all this I'd
be open.

Thanks for looking

The problem that is causing the error is attempting to pass a reference
to the form as an argument in the function call using - this.form -. As
the internally generated onclick handler becomes a method of the A
element the - this - keyword become a reference to that element and A
elements do not have - form - properties. So the argument passed is
undefined and undefined has no properties.

The next problems are the combination of failing to cancel the
navigation using the onclick handler and the internally-suppressed-error
producing formulation of the javascript pseudo protocol in the HREF.

But really that is just the tip of the iceberg. The whole client-side
shopping cart/cookies/widow opening scheme is at best unreliable. Not
appropriate for e-commerce.
