根据另一个数组的值替换一个数组的值

Question

我有以下数组类型

export const images = [
  { id: "000012", label: "night sky", cost: "35" },
  { id: "000013", label: "country road", cost: "16" },
  { id: "000014", label: "baseball game", cost: "12" },
  { id: "000015", label: "horse racing", cost: "24" },
  { id: "000016", label: "bike gathering", cost: "18" },
  ...
  { id: "001138", label: "kite surfing", cost: "25" },

还有下面的第二个数组

const product = [
  { product: "000013" },
  { product: "000016" },
  ...
]

并且我想用我的第一个数组的标签值替换我的产品数组的值。第二个数组保存产品属性中第一个数组的id值。预期结果为：

const product = [
  { product: "country road" },
  { product: "bike gathering" },
]

Answer 1

这里我运行循环遍历每个product然后为它找到对应的image。最后用 image label.

更新了 product 值

const images = [
  { id: "000012", label: "night sky", cost: "35" },
  { id: "000013", label: "country road", cost: "16" },
  { id: "000014", label: "baseball game", cost: "12" },
  { id: "000015", label: "horse racing", cost: "24" },
  { id: "000016", label: "bike gathering", cost: "18" },
  { id: "001138", label: "kite surfing", cost: "25" },
]

const products = [
  { product: "000012" },
  { product: "000013" },
  { product: "000014" },
  
]

products.forEach((p, index) => {
    const image = images.find(({id}) => id === p.product);
    if(image) {
      const newVal = {product: image.label};
      products[index] = {...p, ...newVal};
    }
})

console.log(products)
