I have the shopping cart page where a user can add items dynamically
through ajax as explained in Railscast episode 75. I am using
observe_field to observe the ‘quantity’ and ‘cost’ fields to update
the total field for each item.
This does not work however, for records that are added through the
Ajax. How can i name the fields and observe them as i have explained?
is observing the best way to go?
Really appreciate any help.
