javascript - 在 jQuery 中使用整数字符串类型对数组进行排序

Question

我有一个字符串类型的整数数组。

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

输出

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

---

我还会有一个混合类型数组。例如

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排序。

Answer 1

正如其他人所说，您可以编写自己的比较函数:

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"]
