javascript 将数组与对象数组进行比较

Question

我正在处理一些 Angular 代码。我们的目标是尽可能少地使用 Angular 1.x 功能，因为它很快就会被重构。

我正在比较一个数组

  let subscription = [
  "Cinemax Subscription", 
  "Disney Subscription", 
  "Encore Subscription", 
  "Epix Subscription", 
  "HBO Subscription", 
  "MLB Subscription", 
  "NBA Subscription", 
  "NHL Subscription", 
  "Division"
]

到一个包含另一个数组的具有键值关系的对象数组。

let profiles = [
    {
        name:"1+ Adults in Household",
        qualifiers: [
            {
                name: 'Number of adults in the household'
            }
        ]
    },
    {
        name: '75k',
        qualifers: [
            {
                name: 'Division'
            },
            {
                name: 'Income'
            }
        ]
    },
    {
        name: 'Time Warner',
        qualifers: [
            {
                name: 'Division'
            }
        ]
    }
]

我在索引和循环方面遇到了困难。

let = profilesFiltered = [];

最初我尝试使用过滤器和 angular.for 每个来比较数组。

let filteredProfiles = subscription.filter( function (src) {
    angular.forEach(profiles, function (key, index) {
        if(src === key.qualifiers[index].name) {
            profilesFiltered.push(key);
        }
    })
});

我在 if 语句中看到

key.qualifiers[index].name // 'Number of adults in the household'

与

相比，开始是正确的

subscription[0]   // however, it will continue to 1 on the first object which isn't there.  

我看到它是如何开始失败的。但我不确定如何正确循环 **profiles ** 数组中的限定符。

期望的结果是那些房子Division，它是索引中的最后一个数组项。

profilesFiltered = [
    {
    name: '75k',
    qualifers: [
      {
        name: 'Division'
      },
      {
        name: 'Income'
      }
    ]
  },
  {
      name: 'Time Warner',
      qualifers: [
          {
              name: 'Division'
          }
      ]
  }
]

此时我们非常感谢任何反馈。

谢谢

只需使用 filter() 和 some() 组合来过滤配置文件:

profiles.filter(v => v.qualifiers.some(q => subscription.includes(q.name)));

let subscription = [
  "Cinemax Subscription",
  "Disney Subscription",
  "Encore Subscription",
  "Epix Subscription",
  "HBO Subscription",
  "MLB Subscription",
  "NBA Subscription",
  "NHL Subscription",
  "Division"
]

let profiles = [{
    name: "1+ Adults in Household",
    qualifiers: [{
      name: 'Number of adults in the household'
    }]
  },
  {
    name: '75k',
    qualifiers: [{
        name: 'Division'
      },
      {
        name: 'Income'
      }
    ]
  },
  {
    name: 'Time Warner',
    qualifiers: [{
      name: 'Division'
    }]
  }
]

let res = profiles.filter(v => v.qualifiers.some(q => subscription.includes(q.name)));


console.log(res)
