Question

我有以下Javascript数组：

myArr = [[["One"],["First","Fourth","Third"]], 
         [["Two"],["First","Second","Third"]], 
         [["Three"],["First","Third"]], 
         [["One two"],["Fourth","Second","Third"]], 
         [["One three"],["Fourth","Third"]], 
         [["One two three"],["Second","Third"]]];

我需要这样排序，所以我得到：

[[["One"],["First","Fourth","Third"]], 
 [["One three"],["Fourth","Third"]], 
 [["One two"],["Fourth","Second","Third"]], 
 [["One two three"],["Second","Third"]], 
 [["Three"],["First","Third"]], 
 [["Two"],["First","Second","Third"]]]

我假设我可以使用myArr.sort()并获得正确排序的数组。它适用于平面阵列，但不适用于嵌套数组。当我使用myArr.sort()时，我得到：

[[["One three"],["Fourth","Third"]], 
 [["One two three"],["Second","Third"]], 
 [["One two"],["Fourth","Second","Third"]], 
 [["One"],["First","Fourth","Third"]], 
 [["Three"],["First","Third"]], 
 [["Two"],["First","Second","Third"]]]

这对我来说毫无意义。 JS排序如何得到结果？我如何得到我需要的结果。

丑陋的方式：

myArr.sort((a, b) => (a[0][0]).localeCompare(b[0][0]))

基本上你想要将每个数组的第一个元素与彼此的

进行比较

myArr = [[["One"],["First","Fourth","Third"]], 
         [["Two"],["First","Second","Third"]], 
         [["Three"],["First","Third"]], 
         [["One two"],["Fourth","Second","Third"]], 
         [["One three"],["Fourth","Third"]], 
         [["One two three"],["Second","Third"]]];
         
const sorted = myArr.sort((a, b) => (a[0][0]).localeCompare(b[0][0]));

console.log(sorted);
