javascript - 电子表格的 Javascript 对象中的输出数组

Question

这是我的代码。

function order() {

  //declare things
var order = [3, 2, 1, 0]
var testOne = [2, 3, 7, 4]
var testTwo = ["c", "b", "a", "d"]


//sort by order
  var collatedArray = [];
    for (var i = 0; i < order.length; i++)
    {
        index = order[i];
        var collated =
        {
           test1 : testOne[index],
           test2 : testTwo[index]
        }
        collatedArray.push(collated);
    }


  //Create output
  var output = [];
  for (i=0; i<collatedArray.length; i++)
  {
    output[i] = collatedArray[i].test1
  }

return output
}

当前的输出仅为 collat​​edArray[i].test1，它给出:

4, 7, 3, 2

如果我将 output[i] = collat​​edArray[i].test1 更改为 test2，我得到:

d, a, b, c

我只想输出整个 collat​​edArray (test1 和 test2)，以便我得到:

4, 7, 3, 2
d, a, b, c

无需输出变量，或转换回数组。信息就在那里，我只是不知道如何将其取出。对编码非常陌生，只是不明白在这里做什么:(谢谢

Answer 1

将输出调整为包含两个数组的数组；在最后一个 for 循环中，使用 collat​​edArray[0][i].test1 和 collat​​edArray[1] 处的值填充 output 中的每个数组[i].test2

  // Create output
  var output = [[], []]; 
  for (i=0; i<collatedArray.length; i++)
  {
    output[0][i] = collatedArray[i].test1;
    output[1][i] = collatedArray[i].test2;
  }

function order() {

  //declare things
  var order = [3, 2, 1, 0]
  var testOne = [2, 3, 7, 4]
  var testTwo = ["c", "b", "a", "d"]


  //sort by order
  var collatedArray = [];
  for (var i = 0; i < order.length; i++) {
    index = order[i];
    var collated = {
      test1: testOne[index],
      test2: testTwo[index]
    }
    collatedArray.push(collated);
  }


  //Create output
  var output = [
    [],
    []
  ];
  for (i = 0; i < collatedArray.length; i++) {
    output[0][i] = collatedArray[i].test1;
    output[1][i] = collatedArray[i].test2;
  }

  return output
}

console.log(order())
