如何使用 Object 中的多個條件對 Javascript 中的數組進行多重過濾？

Question

您好，我正在嘗試根據來自 object 的多個條件過濾一系列產品，但我無法理解它。 有人可以送我正確的方向嗎？

條件（對象）

const Conditionobject = {
Brand: ["msi", "acer"]
Processor: ["intel i7", "intel i9"]
Refreshrate: ["165 hz"]
}

產品（數組）

const AllProducts= [ 
{
Productname: Acer Nitro,
Specifications: { Brand: "acer", Processor: "intel i7", Refreshrate: "144 hz"}
},
{
Productname: Msi Katana,
Specifications: { Brand: "msi", Processor: "intel i7", Refreshrate: "165 hz"}
},
{
Productname: Acer Aspire,
Specifications: { Brand: "acer", Processor: "intel i9", Refreshrate: "165 hz"}
},
]

決賽：過濾陣列產品

根據給定條件，最終過濾的產品數組應包含產品名稱為Msi Katana和Acer Aspire的對象。 有人可以向我解釋如何實現這一目標嗎？

Answer 1

您可以迭代所有條件並過濾產品。

 const conditions = { Brand: ["msi", "acer"], Processor: ["intel i7", "intel i9"], Refreshrate: ["165 hz"] }, products = [{ Productname: "Acer Nitro", Specifications: { Brand: "acer", Processor: "intel i7", Refreshrate: "144 hz" } }, { Productname: "Msi Katana", Specifications: { Brand: "msi", Processor: "intel i7", Refreshrate: "165 hz" } }, { Productname: "Acer Aspire", Specifications: { Brand: "acer", Processor: "intel i9", Refreshrate: "165 hz" } }], result = products.filter(product => Object.entries(conditions).every(([key, values]) => values.includes(product.Specifications[key])) ) console.log(result);
