AJAX Libraries - Continuous Forms

The code in that link could be much simpler using jQuery.

It sounds like what you're doing is in a closed environment like a POS. If you're using barcode scanners then this should all be a no-brainer, as there's no typing involved.

The most flexible method would be to have a set of fields where you could "add one", like in the example, but also have a bulk entry where you'd allow the user to enter their orders into a very tall textarea in a certain format, and you'd parse the data and create the order from that. The textarea would be great not only for the barcode scanners, but also for people who have advanced skills and would rather just paste their large order than have to retype it into a bunch of small text inputs.
