javascript - 根据值获取键名列表-Javascript

我想获得一个基于我检查的值的键名列表。

这就是我所拥有的。

const data = {
  "DE": "ARUN",
  "HI": "ARUN",
  "PR": "ARUN",
  "TX": "ARUN",
  "MA": "ARUN",
  "MD": "CHARLES,BRANDON,DAVID,ARUN",
  "IA": "ARUN",
  "ME": "ARUN",
  "ID": "ARUN",
  "MI": "ARUN",
  "UT": "ARUN",
  "MN": "ARUN",
  "MO": "ARUN",
  "IL": "ARUN",
  "IN": "ARUN",
  "MS": "ARUN",
  "MT": "ARUN",
  "AK": "ARUN",
  "AL": "ARUN",
  "VA": "ARUN",
  "AR": "ARUN",
  "AS": "ARUN",
  "VI": "ARUN",
  "NC": "ARUN",
  "ND": "ARUN",
  "NE": "ARUN",
  "RI": "ARUN",
  "AZ": "ARUN",
  "NH": "ARUN",
  "NJ": "ARUN",
  "VT": "ARUN",
  "NM": "ARUN",
  "FL": "ARUN",
  "NV": "ARUN",
  "WA": "ARUN",
  "NY": "ARUN",
  "SC": "ARUN",
  "SD": "ARUN",
  "WI": "ARUN",
  "OH": "ARUN",
  "GA": "ARUN",
  "OK": "ARUN",
  "CA": "ARUN",
  "WV": "ARUN",
  "WY": "ARUN",
  "OR": "ARUN",
  "KS": "ARUN",
  "CM": "ARUN",
  "CO": "ARUN",
  "GU": "ARUN",
  "KY": "ARUN",
  "CT": "ARUN",
  "PA": "ARUN",
  "LA": "ARUN",
  "TN": "ARUN",
  "DC": "ARUN"
}

const name = 'BRANDON'

const newMappedData = Object.keys(data).map(key => {
  return {
    [key]: data[key].split(',')
  }
})

const filteredData = newMappedData.filter(item => Object.values(item).includes(name))


console.log(filteredData)

在上面的示例中，当我们输入“BRANDON”时，结果应仅为['MD']，如果为“ARUN”，则应给我['DE', 'HI', 'PR',...]
请指教。

最佳答案

如果您使用includes，甚至不需要split。另外，您不需要使用map来创建新的数组:

const data = {
  "DE": "ARUN",
  "HI": "ARUN",
  "PR": "ARUN",
  "TX": "ARUN",
  "MA": "ARUN",
  "MD": "CHARLES,BRANDON,DAVID,ARUN",
  "IA": "ARUN",
  "ME": "ARUN",
  "ID": "ARUN",
  "MI": "ARUN",
  "UT": "ARUN",
  "MN": "ARUN",
  "MO": "ARUN",
  "IL": "ARUN",
  "IN": "ARUN",
  "MS": "ARUN",
  "MT": "ARUN",
  "AK": "ARUN",
  "AL": "ARUN",
  "VA": "ARUN",
  "AR": "ARUN",
  "AS": "ARUN",
  "VI": "ARUN",
  "NC": "ARUN",
  "ND": "ARUN",
  "NE": "ARUN",
  "RI": "ARUN",
  "AZ": "ARUN",
  "NH": "ARUN",
  "NJ": "ARUN",
  "VT": "ARUN",
  "NM": "ARUN",
  "FL": "ARUN",
  "NV": "ARUN",
  "WA": "ARUN",
  "NY": "ARUN",
  "SC": "ARUN",
  "SD": "ARUN",
  "WI": "ARUN",
  "OH": "ARUN",
  "GA": "ARUN",
  "OK": "ARUN",
  "CA": "ARUN",
  "WV": "ARUN",
  "WY": "ARUN",
  "OR": "ARUN",
  "KS": "ARUN",
  "CM": "ARUN",
  "CO": "ARUN",
  "GU": "ARUN",
  "KY": "ARUN",
  "CT": "ARUN",
  "PA": "ARUN",
  "LA": "ARUN",
  "TN": "ARUN",
  "DC": "ARUN"
}

const name = 'BRANDON'

const filteredData = Object.keys(data).filter(key => data[key].includes(name))

console.log(filteredData)
