Question

我的对象

{
  bookingDate: "2019-10-17",
  createDate: "2019-10-14T12:40:08.624",
  lastUpdateTime: "2019-10-17T16:04:30.973",
  p2p00: true,
  p2p01: true,
  p2p02: true,
  p2p03: true,
  p2p04: true,
  response: null,
  sa00: 0,
  sa01: 0,
  sa02: 0,
  sa03: 0,
  sa04: 0,
  sa05: 0,
  srr00: false,
  srr01: false,
  srr02: false,
  srr03: false,
  srr04: false,
  srr05: false,
  sup00: 0,
  sup01: 0,
  sup02: 0,
  sup03: 0,
  sup04: 0,
  sup05: 0
}

我想做的通用对象数组

[
  {p2p00: true, sa00: 0, srr00: false, sup00: 0},
  {p2p01: true, sa01: 0, srr01: false, sup01: 0},
  {p2p02: true, sa02: 0, srr02: false, sup02: 0},
  {p2p03: true, sa03: 0, srr03: false, sup03: 0},
  {p2p04: true, sa04: 0, srr04: false, sup04: 0}
]

如何使用对象中包含所需字段的对象组成数组？我只想创建一个包含我想要的字段的数组

Answer 1

执行以下操作：

var obj = {
  bookingDate: "2019-10-17",
  createDate: "2019-10-14T12:40:08.624",
  lastUpdateTime: "2019-10-17T16:04:30.973",
  p2p00: true,
  p2p01: true,
  p2p02: true,
  p2p03: true,
  p2p04: true,
  response: null,
  sa00: 0,
  sa01: 0,
  sa02: 0,
  sa03: 0,
  sa04: 0,
  sa05: 0,
  srr00: false,
  srr01: false,
  srr02: false,
  srr03: false,
  srr04: false,
  srr05: false,
  sup00: 0,
  sup01: 0,
  sup02: 0,
  sup03: 0,
  sup04: 0,
  sup05: 0
};

var ar = [];
ar.push({'p2p00': obj.p2p00});
ar.push({'p2p04': obj.p2p04});
console.log(ar);

您可以使用map功能。例如：

const obj = {
  name: 'John',
  lastName: 'Doe',
  age: 21
}

const newObj = obj.map(x => {
  return {
    name: x.name,
    age: x.age
  }
})

console.log(newObj); // output: { name: John, age: 21}

const obj = {
  bookingDate: "2019-10-17",
  createDate: "2019-10-14T12:40:08.624",
  lastUpdateTime: "2019-10-17T16:04:30.973",
  p2p00: true,
  p2p01: true,
  p2p02: true,
  p2p03: true,
  p2p04: true,
  response: null,
  sa00: 0,
  sa01: 0,
  sa02: 0,
  sa03: 0,
  sa04: 0,
  sa05: 0,
  srr00: false,
  srr01: false,
  srr02: false,
  srr03: false,
  srr04: false,
  srr05: false,
  sup00: 0,
  sup01: 0,
  sup02: 0,
  sup03: 0,
  sup04: 0,
  sup05: 0
};

let tmpObj = {}

for(let key in obj) {
  let match = key.match('0[0-9]$');
  if (match) {
    if (!tmpObj[match[0]]) {
      tmpObj[match[0]] = {}
    }
    tmpObj[match[0]][key] = obj[key];
  }
}

const result = Object.values(tmpObj)

角度对象到对象数组
