Ajax field in products page I have downloaded the Commerce Kickstart distro. In the product page there is a quantity field which you can use to enter your custom value; I want to display the total cost of current product in AJAX. Is it possible?
There is no such default functionality in drupal commerce. 

Commerce Cart Ajax

This module will ajaxify your cart page. If you need this in product detail page then you can build a custom module for that with Ajax Api in Drupal 7
