backgroundUpdateCart
Method Signature void backgroundUpdateCart()
Description
Updates all the fields on a cart, except for the item information. The cart does not have to be passed ot this method because the method knows to submit the global cart variable. This method is used to update the cart inside of UltraCart without using the return result to modify the global cart object. This method should not be called directly. Instead use triggerBackgroundUpdateCart() on your on* handlers. This helper method will set a 2.5 second timeout and then fire the backgroundUpdate call automatically. If they continue typing, etc. then the timer is automatically reset. This drasticly minimizes the amount of traffic back and forth to the server while still effectively capturing the customer's information for abandon marketing.
