如何像C＃这样在Javascript中对数组进行排序？

Question

I would like to sort an array in JavaScript as asc. After I used sort method, the result is like below.

[ '123, '12', '1A1', '1A', '1a', 'A1', 'A2', 'AB', 'A', 'Ab', 'a1', 'a2', 'aB', 'ab' ]

When I'm using sort Array.Sort() by C#, the result is like below.

{ "12", "123", "1a", "1A", "1A1", "A", "a1", "A1", "a2", "A2", "ab", "aB", "Ab", "AB" }

Actually the C# sort way is what I want, so how to implement it in JavaScript? Has anyone completed this task before? A comparator function is really appreciate.

Array.prototype.sort uses string comparison by default. It seems you want to compare case insensitive - you could pass in a comparator function that uses toLowerCase (but beware of the difference with .toLocaleLowerCase !):

a.sort(function(a, b) {
  a = a.toLowerCase(); b = b.toLowerCase();
  return a > b ? 1 : a < b ? -1 : 0;
});
