Question

我正在考虑如何根据用户添加的产品计算每个工作日的总价的解决方案。例如，我需要从嵌套在 productsAddedToPackage 对象内的两个价格数组中获取星期一的所有价格。周一产品 1 和产品 2 的价格是 => 1.11 和 4.44。所以，这应该等于 5.55。然后我需要将星期一的 packagePrices 更新为从 0.00 到 5.55。关于如何进行此类计算的任何想法？

这就是我最初的工作日总价的样子：

packagePrices: [
            {
                dayOfWeek: 1,
                dayOfWeekName: 'Monday',
                price: 0.00
            },
            {
                dayOfWeek: 2,
                dayOfWeekName: 'Tuesday',
                price: 0.00
            },
            {
                dayOfWeek: 3,
                dayOfWeekName: 'Wednesday',
                price: 0.00
            },
            {
                dayOfWeek: 4,
                dayOfWeekName: 'Thirsday',
                price: 0.00
            },
            {
                dayOfWeek: 5,
                dayOfWeekName: 'Friday',
                price: 0.00
            },
            {
                dayOfWeek: 6,
                dayOfWeekName: 'Saturday',
                price: 0.00
            },
            {
                dayOfWeek: 0,
                dayOfWeekName: 'Sunday',
                price: 0.00
            },
        ],

这里是所有产品

我将改变“包装价格”以接受一个属性可以是一个具有价格和id的对象数组

packagePrices: [
            {
                dayOfWeek: 1,
                dayOfWeekName: 'Monday',
                purchases: [{price: 1.11, id: "00000000-0000-0000-0000-000000000000"}, 
                {price: 4.44, 
                 id:"00000000-0000-0000-0000-000000000000"}],
                price: 0.00
            },

所以每次有人进行新购买时，您都可以创建一个函数来映射产品并获取价格和 id 并将其推送到购买数组中，然后您只需在购买数组中进行映射并对价格求和
