js库存数据组装?

Question

`

// 根据attributes里specifications数组中的id跟skus里specificationIds做关联, 如果相等则将数据相乘添加到新的对象当中
const data = {
  attributes: [
    {
      id: '2851',
      name: '衣柜',
      specifications: [
        {
          attributeId: '2851',
          name: '黑色',
          id: '4685'
        },
        {
          attributeId: '2851',
          name: '白色',
          id: '4686'
        }
      ]
    },
    {
      id: '2852',
      name: '床',
      specifications: [
        {
          attributeId: '2852',
          goodsId: '1182246',
          name: '浅黑色',
          id: '4687'
        },
        {
          attributeId: '2852',
          goodsId: '1182246',
          name: '浅蓝色',
          id: '4688'
        }
      ]
    }

// 实际想要得到的效果
const sku = [

{
  // 根据id匹配, 将attributes中的属性添加到sku里, skus的price和skuSn一一对应
  childProductSpec: {
    床: "浅黑色",
    衣柜: "黑色"
  },
  isUse: true,
  price: '1288',

    衣柜: "白色"
  },

// 这样操作得到的数据不符, 数据重复

  for (let i = 1; i < attributes.length; i++) {
    this.value = attributes[i].name

      }

// 上面处理之后的数据, 数据有重复

你这个源码不全啊。 跑不起来 我就自己写了个方法

用个lodash库

let result = [];
data.attributes.forEach(attribute => {
  attribute.specifications.forEach(specification => {
    const sku = _.find(data.skus, sku => sku.specificationIds.indexOf(specification.attributeId));
    if(sku){
      result.push({
        childProductSpec: {
          [attribute.name]: specification.name
        },
        isUse: true,
        price: sku.price,
        skuSn: sku.skuSn
      },)
    }else{
      // specifications 和 specificationIds不相等的情况

      // dosomething...
    }
  })
})
