如何在 c# 中使用 Webmethod 和 Ajax 创建购物车？

Question

I want to create a shopping cart in that the products would be fetched from database. I would create a web method but need to call this webmethod using ajax.

How to refresh the cart on the same page whenever new item is added using ajax?

Answer 1

You will need to initialise your shopping cart at load time

let shoppingCart = []; // array of objects

First define what information you want to store in it that will be the attributes of your cart item object for instance: id, quantity, lable, price, sum start from that and give us feed back
