javascript数组排序字符串和数字

Question

我想用字符串和数字对数组进行排序。

var toSort = ['100', 'Calc', '30', '43', '52', '16', '10', '11', '12', 'Calc', '2', 'N/A', '8'];

预期的行为是当对字符串进行排序时，将在两种状态（asc 和 desc）的列表末尾排序，例如： 升序：

['2','8','10','11','12','16','30','43','52','100','Calc','Calc','N/A']

描述：

['100','52','43','30','16','12','11','10','8','2','Calc','Calc','N/A']

我有它用于 asc 状态：

toSort.sort(function (a,b) {
  if (a === 'Calc') return 1;
  else if (a === 'N/A') return 1;
  else return a.localeCompare(b, undefined, { numeric: true});
});

console.log(toSort);

关于 desc 状态的任何想法？ tnx

Answer 1

您可以检查值是否为isFinite。

const
    array = ['100', 'Calc', '30', '43', '52', 'Calc', '16', '10', 'N/A', '123', '11', '12', 'Calc', '2', 'N/A', '8'];

array.sort((a, b) => isFinite(b) - isFinite(a) || a - b || a.localeCompare(b));
console.log(...array);

array.sort((a, b) => isFinite(b) - isFinite(a) || b - a || a.localeCompare(b));
console.log(...array);

您可以创建一个具有 2 个属性 numbers、strings 和 reduce 的对象，之后您可以将该对象传递给您可以进行相应排序并返回结果。

finalResult = result after sorting numbers + result after sorting strings.

var toSort = [
  "100",
  "Calc",
  "30",
  "43",
  "52",
  "16",
  "10",
  "11",
  "12",
  "Calc",
  "2",
  "N/A",
  "8",
];

function sort({ strings, numbers }, type) {
  if (type === "asc") {
    return [
      ...numbers.sort((a, b) => a - b),
      ...strings.sort((a, b) => (a > b ? 1 : -1)),
    ];
  } else {
    return [
      ...numbers.sort((a, b) => b - a),
      ...strings.sort((a, b) => (a > b ? -1 : 1)),
    ];
  }
}

const obj = toSort.reduce(
  (acc, curr) => {
    if (/\d+/g.test(curr)) acc.numbers.push(curr);
    else acc.strings.push(curr);
    return acc;
  }, {
    strings: [],
    numbers: []
  }
);

console.log(sort(obj, "asc"));
console.log(sort(obj, "dsc"));
