在jQuery中使用整数字符串类型排序数组 [英] sort array with integer strings type in jQuery

问题描述

我有一个string类型的整数数组。

I have a array of integers of type string.

var a = ['200','1','40','0','3'];

输出

output

>>> var a = ['200','1','40','0','3'];
console.log(a.sort());
["0", "1", "200", "3", "40"]

我还有一个混合型数组。例如。

I'll also have a mixed type array. e.g.

var c = ['200','1','40','apple','orange'];

输出

>>> var c = ['200','1','40','apple','orange']; console.log(c.sort());
["1", "200", "40", "apple", "orange"]

============================================== ====

字符串类型的整数未分类。

==================================================
The integers of string type gets unsorted.

推荐答案

正如其他人所说，你可以编写自己的比较函数：

As others said, you can write your own comparison function:

var arr = ["200", "1", "40", "cat", "apple"]
arr.sort(function(a,b) {
  if (isNaN(a) || isNaN(b)) {
    return a > b ? 1 : -1;
  }
  return a - b;
});

// ["1", "40", "200", "apple", "cat"]
