JavaScript - 从多个数组创建对象

Question

我有 3 个数组:

colors = ['green', 'red', 'black'];
positionToId = [0, 32, 15];
results = ["0", "1", "2"];

并且想要实现这样的目标:

{results: '0', 'positionToId: '31', colors: 'black'},
{results: '1', 'positionToId: '2', colors: 'red'},
{results: '2', 'positionToId: '11', colors: 'black'}

我该怎么做？ 谢谢。

Answer 1

您想将这些数组合并为一个对象数组，该数组具有key => value。

最简单的方法是 map其中之一。

The map() method creates a new array with the results of calling a provided function on every element in the calling array.

例子:

colors = ['green', 'red', 'black'];
positionToId = [0, 32, 15];
results = ["0", "1", "2"];


console.log(results.map((result,i) => {
  return {
    results: results[i], 
    positionToId: positionToId[i],
    colors: colors[i],
  };
}));
