基于嵌套对象过滤嵌套对象数组

乙肝

我希望根据嵌套对象中的值过滤数组。

我的代码如下查找包含“Credit”的“inventory_type”的产品，但我收到一条错误消息，指出 some 不是函数，需要一些指导以了解在数组中深度搜索的最佳方法

let object = [{
  "summary": [{
    "count": 2,
    "inventory_region": "England & Wales",
    "inventory_type": "Add-on"
  }, {
    "count": 2,
    "inventory_region": "England & Wales",
    "inventory_type": "Credit"
  }, {
    "count": 2,
    "inventory_region": "England & Wales",
    "inventory_type": "Social-boost"
  }, {
    "count": 2,
    "inventory_region": "Scotland",
    "inventory_type": "Add-on"
  }, {
    "count": 2,
    "inventory_region": "Scotland",
    "inventory_type": "Credit"
  }],
  "products": [{
    "count": 2,
    "display_label_short": "14 Day Add On E&W",
    "inventory_region": "England & Wales",
    "display_label": "14 Day Add On E&W",
    "inventory_type": "Add-on"
  }, {
    "count": 2,
    "display_label_short": "Standard 28 Day Listing E&W",
    "inventory_region": "England & Wales",
    "display_label": "Standard 28 Day Listing E&W",
    "inventory_type": "Credit"
  }, {
    "count": 2,
    "display_label_short": "14 Day Boost E&W",
    "inventory_region": "England & Wales",
    "display_label": "14 Day Boost E&W",
    "inventory_type": "Social-boost"
  }, {
    "count": 2,
    "display_label_short": "14 Day Add On SCO",
    "inventory_region": "Scotland",
    "display_label": "14 Day Add On SCO",
    "inventory_type": "Add-on"
  }, {
    "count": 2,
    "display_label_short": "Standard 28 Day Listing SCO",
    "inventory_region": "Scotland",
    "display_label": "Standard 28 Day Listing SCO",
    "inventory_type": "Credit"
  }],
  "company_id": 2876909,
  "company_name": "Automated Testing"
}]


let newArr = object.map(objects => {
  return objects.products.filter(products => {
    products.some(product => product.inventory_type === 'Credit')
  })
})

console.log(newArr)

您的“内积”不是数组，而只是一个产品

 let object = [{ "summary": [{ "count": 2, "inventory_region": "England & Wales", "inventory_type": "Add-on" }, { "count": 2, "inventory_region": "England & Wales", "inventory_type": "Credit" }, { "count": 2, "inventory_region": "England & Wales", "inventory_type": "Social-boost" }, { "count": 2, "inventory_region": "Scotland", "inventory_type": "Add-on" }, { "count": 2, "inventory_region": "Scotland", "inventory_type": "Credit" }], "products": [{ "count": 2, "display_label_short": "14 Day Add On E&W", "inventory_region": "England & Wales", "display_label": "14 Day Add On E&W", "inventory_type": "Add-on" }, { "count": 2, "display_label_short": "Standard 28 Day Listing E&W", "inventory_region": "England & Wales", "display_label": "Standard 28 Day Listing E&W", "inventory_type": "Credit" }, { "count": 2, "display_label_short": "14 Day Boost E&W", "inventory_region": "England & Wales", "display_label": "14 Day Boost E&W", "inventory_type": "Social-boost" }, { "count": 2, "display_label_short": "14 Day Add On SCO", "inventory_region": "Scotland", "display_label": "14 Day Add On SCO", "inventory_type": "Add-on" }, { "count": 2, "display_label_short": "Standard 28 Day Listing SCO", "inventory_region": "Scotland", "display_label": "Standard 28 Day Listing SCO", "inventory_type": "Credit" }], "company_id": 2876909, "company_name": "Automated Testing" }] 

let newArr = object.map(objects => objects.products.filter(product =>
  product.inventory_type === 'Credit'
))

console.log(newArr)
