将两个数组的值合并为对象 [英] Combine the values of two arrays into object

问题描述

我有两个数组:

array1 = ["Bob", "John", "Dave"];
array2 = [1, 2, 3];

是否将两者结合成一个包含对象的javascript数组:

Is there combine the two into a javascript array filled with objects that looks like:

[
  {meta: 'Bob', value: 1 },
  {meta: 'John', value: 2},
  {meta: 'Dave', value: 3}
]

推荐答案

这是实现它的方法之一.您可以使用 Array#forEach 函数遍历 array1 中的每个元素.然后，创建一个空对象并设置指定的属性-在您的情况下为 meta 和 value .然后-给它分配元素，然后将其推入 arr 变量.

It's one of the ways how to achieve it. You can use Array#forEach function to iterate over every element from array1. Then, create empty object and set specified properties - in your case: meta and value. Then - assign elements to it and just push it into the arr variable.

var array1 = ["Bob", "John", "Dave"],
    array2 = [1, 2, 3],
    arr = [];

array1.forEach(function(v,i){
  var obj = {};
  obj.meta = v;
  obj.value = array2[i];
  arr.push(obj);
});

console.log(arr);
