Javascript-数组排序 [英] Javascript - arrays sorting

问题描述

我有两个数组:

keys_array   = [2,4,5,8,9]
values_array = ['two','four','five','eight','nine']

我需要得到:

#transitional result
#values sorted alphabetically
sorted_by_value_name_array = [
  ['8','eight'],
  ['5','five'],
  ['4','four'],
  ['9','nine'],
  ['2','two']
]

#final result  
sorted_keys_array = [8,5,4,9,2]

如何使用javascript或jQuery实现此目标?

How can i achieve this with javascript or jQuery?

推荐答案

var keys_array   = [2,4,5,8,9];
var values_array = ['two','four','five','eight','nine'];
var new_array = [];
for(var i=0; i<keys_array.length; i++){
    new_array.push([keys_array[i],values_array[i]]);
}

console.log(new_array.sort(function(a,b){ return a[1] < b[1] ? -1 : 1; }));
