HomeBackend DevelopmentPHP Tutorialjavascript - 餐饮类 菜单前端数据存储设计问题

如题: 在做餐饮类 在线点菜目前菜单 主要分为四种

  1. 单品 即该商品不包含任何的附加属性 如: 酸 辣等属性
  2. 复杂单品, 即该商品 包含一些属性 如 酸 辣等属性
  3. 自由组合商品, 即一套商品,如果 火锅,毛肚,等等 从中选择几种菜品
  4. 套餐,套餐又分为 固定套餐 即 价格和其中的 商品都是固定的; 不固定套餐 即 价格是固定的,但是需要用户从套餐中自己选择其中的一种或者几种(几选几的问题);

目前数据都存储在 sessionstorage 中, 但是购物车的的数据组织很混乱 导致 修改 和 删除购物车菜品 业务逻辑变的非常复杂.

前端将上述商品加入购物车中,过程当然包含 增加减少删除和修改,应该如何组织前端存储的数据格式方便做以上各种操作呢?

单品和复杂单品有什么区别,我看饿了么上口味都是单点的,没有复杂单品啊
单品:{'name':a,"taste":b}
自由组合:[{若干个单品}]

大json不行么,反正这个数值也不是频繁变动的,存个大json应该没什么影响吧
