javascript - 根据给定值通过键过滤对象

Question

我正在尝试根据给定值将接受的值与对象隔离acceptedValues = ["250", "300"]，因此结果应该是两个不同的数组arrAcceptedValues, notArrAcceptedValues 我想我仍然缺少查找不匹配值的逻辑!希望有人能解释一下

const acceptedValues = ["250", "300"];

const myObj = {
  250: [1222, 1330, 1334, 1336, 6130, 6154, 6186, 6311, 6314],
  300: [1112, 1146, 1186, 1224, 6657],
  315: [710, 717],
  545: [4778],
  700: [637, 969, 1321, 6534, 1324, 6898, 738, 6899],
  750: [6323],
  900: [1717, 1718, 1720],
  1500: [5824, 5830, 5831, 5835, 5919, 5920, 5989],
};

let arrAcceptedValues = [];
let notArrAcceptedValues = [];
for (let iterator of acceptedValues) {
  // find all values that IS contains in the myObj array ["250", "300"]
  if (myObj[iterator]) {
    const returnData = myObj[iterator];
    arrAcceptedValues.push(returnData);
  }
  // find all values that NOT contains in the myObj array ["250", "300"]
  for (const keyIterator of Object.keys(myObj)) {
    if (keyIterator !== iterator) {
      notArrAcceptedValues.push(Object.values(myObj));
    }
  }
}
console.log("arrAcceptedValues", arrAcceptedValues);
console.log("notArrAcceptedValues", notArrAcceptedValues);

您可以使用 Object.keys 轻松获得结果, forEach和 includes

您甚至可以制作一个衬垫:

Object.keys(myObj).forEach((k) =>(acceptedValues.includes(k) ? arrAcceptedValues : notArrAcceptedValues).push(myObj[k]));

const acceptedValues = ["250", "300"];

const myObj = {
  250: [1222, 1330, 1334, 1336, 6130, 6154, 6186, 6311, 6314],
  300: [1112, 1146, 1186, 1224, 6657],
  315: [710, 717],
  545: [4778],
  700: [637, 969, 1321, 6534, 1324, 6898, 738, 6899],
  750: [6323],
  900: [1717, 1718, 1720],
  1500: [5824, 5830, 5831, 5835, 5919, 5920, 5989],
};

let arrAcceptedValues = [];
let notArrAcceptedValues = [];

Object.keys(myObj).forEach((k) => {
  acceptedValues.includes(k)
    ? arrAcceptedValues.push(myObj[k])
    : notArrAcceptedValues.push(myObj[k]);
});

console.log(arrAcceptedValues);
console.log(notArrAcceptedValues);

/* This is not a part of answer. It is just to give the output fill height. So IGNORE IT */
.as-console-wrapper { max-height: 100% !important; top: 0; }

或

const acceptedValues = ["250", "300"];

const myObj = {
  250: [1222, 1330, 1334, 1336, 6130, 6154, 6186, 6311, 6314],
  300: [1112, 1146, 1186, 1224, 6657],
  315: [710, 717],
  545: [4778],
  700: [637, 969, 1321, 6534, 1324, 6898, 738, 6899],
  750: [6323],
  900: [1717, 1718, 1720],
  1500: [5824, 5830, 5831, 5835, 5919, 5920, 5989],
};

let arrAcceptedValues = [];
let notArrAcceptedValues = [];

Object.keys(myObj).forEach((k) =>(acceptedValues.includes(k) ? arrAcceptedValues : notArrAcceptedValues).push(myObj[k]));

console.log(arrAcceptedValues);
console.log(notArrAcceptedValues);

/* This is not a part of answer. It is just to give the output fill height. So IGNORE IT */
.as-console-wrapper { max-height: 100% !important; top: 0; }
