Codecanyon - jQuery Price Calculator Pro (RIP) | 1,15 MB
jQuery Price Calculator Pro is a clean, simple, progressive price calculator script which allows you to add a running total to an order form, giving your customers a precise idea of how much their configuration will cost.
It works with radio buttons, checkboxes, drop downs (select), text areas, and text inputs. You can configure the total price box to float at the top of the screen, always staying in view, as well as the signs before and after the price (i.e. taking ‘5’ -> ’$5 USD ’, ’$5 AUD ’, or ’$5 NZD ’, etc.).
