javascript - 使用 jquery 或 javascript 按字母顺序排列多维数组

Question

如果我有一个数组:

myArray = [['0','Mouse'],['1','Dog'],['2','Cat'],['3','Gerbil']];

如何根据动物(在本例中)对数组进行字母顺序排列？

myArray = alpha(myArray);

结果:

myArray = [['2','Cat'],['1','Dog'],['3','Gerbil'],['0','Mouse']];

Answer 1

您可以使用排序功能

var myArray = [['0','Mouse'],['1','Dog'],['2','Cat'],['3','Gerbil']];
console.log(alpha(myArray));

var arr2 = [['5','Mouse'],['0','Mouse'],['1','Dog'],['2','Cat'],['3','G‌​erbil']];
console.log('another array', alpha(arr2));

function alpha(arr) {
  return arr.sort((a, b) => a[1] > b[1]);
}
