How a e-commerce site' shopping cart work? We will try to solve it by JavaScript DOM Trick. In here when you will click the + or - button phone or case number will change and it will also change the price. You will also notice the change in sub-total, tax and total price. The number will increase or decrease perfectly with the button you are clicking.
