根据另一个整数数组对一个数组进行排序 [英] Sort an array based on another array of integers

问题描述

假设我有一个数组:[0,3,4,2,5,1].

我要对数组进行排序，例如:

What I want to do is sort an array such as:

["one", "two", "three", "four", "five", "six"]

因此顺序对应于第一个数组.

So that the order corresponds to the first array.

这将是输出:

["one", "four", "five", "three", "six", "two"]

有没有简单的方法可以做到这一点?

Is there an easy way to accomplish this?

推荐答案

您可以执行以下操作:

function getSorted(arr, sortArr) {
  var result = [];
  for (var i = 0; i < arr.length; i++) {
    console.log(sortArr[i], arr[i]);
    result[i] = arr[sortArr[i]];
  }
  return result;
}
var arr = ["one", "two", "three", "four", "five", "six"];
var sortArr = [0, 3, 4, 2, 5, 1];
alert(getSorted(arr, sortArr));

注意:假设您传入的数组大小相等，如果不是这种情况，则需要添加一些其他检查.

Note: this assumes the arrays you pass in are equivalent in size, you'd need to add some additional checks if this may not be the case.
