按字符串对包含数组的数组进行排序 [英] Sort an array with arrays in it by string

问题描述

我有一个包含多个数组的数组，我想根据这些数组中的某个字符串对数组进行排序.

I have an array that contains several arrays and I would like to order the arrays based on a certain string within those arrays.

var myArray = [
                [1, 'alfred', '...'],
                [23, 'berta', '...'],
                [2, 'zimmermann', '...'],
                [4, 'albert', '...'],
              ];

如何按名称排序，使 albert 排在最前面，zimmermann 排在最后?

How can I sort it by the name so that albert comes first and zimmermann comes last?

如果我可以使用整数进行排序，我知道该怎么做，但字符串让我一无所知.

I know how I would do it if I could use the integer for sorting but the string leaves me clueless.

感谢您的帮助！:)

推荐答案

这可以通过将支持函数作为参数传递给 Array.sort 方法调用来实现.

This can be achieved by passing a supporting function as an argument to the Array.sort method call.

像这样:

 function Comparator(a, b) {
   if (a[1] < b[1]) return -1;
   if (a[1] > b[1]) return 1;
   return 0;
 }

 var myArray = [
   [1, 'alfred', '...'],
   [23, 'berta', '...'],
   [2, 'zimmermann', '...'],
   [4, 'albert', '...'],
 ];

 myArray = myArray.sort(Comparator);
 console.log(myArray);
