Hello, I´m trying to decided what kind of a ordering page I should make.
What I´m trying to do is a page where customer orders product. There can be maybe 25 products. Every product has it´s own price. The customer has a sum of money he can order with. He can´t order more than hes sum of money. I was planing on making a list of the products which shows the price. A quantity column where clicking the quantity box increses (left click) or decreases (right click) the amount. So far quite easy, but how would you do the calculation of the total sum so he sees how much he can still order for? I don´t want to keep reloading the page everytime he takes one product. Would Javascript be the best way out? Maybe a event handler on onChange event. Kenneth
