javascript - Javascript 中的数组排序.. 大写，大写，小，小顺序

Question

var temp=["dy34","fd","FD","av","AV","12esu",1,"DY34",1011,123,101];

当我对数组进行排序时，我得到的结果是:

result = [1,101,123,1011,"12esu","AV","av","dy34","DY34","FD","fd"]

但我需要这样的结果:

result = [1,101,123,1011,"12esu","AV","av","DY34","dy34","FD","fd"]

Answer 1

看来你想

1. 以数字形式比较数组项
2. 如果它们相等，则以不区分大小写的字符串形式进行比较
3. 如果它们也相等，则比较原始形式。

var isNumeric = n => !isNaN(parseFloat(n)) && isFinite(n),
    numberForm = val => isNumeric(val) ? Number(val) : Infinity,
    iStringForm = val => String(val).toUpperCase();

var temp = ["dy34","fd","FD","av","AV","12esu",1,"DY34",1011,123,101];
for (var i = 0; i < temp.length; ++i)
  temp[i] = [numberForm(temp[i]), iStringForm(temp[i]), temp[i]];
temp.sort(function(a, b) {
  for (var i = 0; i < 3; ++i) {
    if (a[i] < b[i]) return -1;
    if (a[i] > b[i]) return +1;
  }
  return 0;
});
for (var i = 0; i < temp.length; ++i)
  temp[i] = temp[i][2];

console.log(temp);
