在Javascript中分配2个数组键值？ [关闭]

Question

我有两个数组

ar1 = ["jhon", "doe", "alex"];
ar2 = ["21", "22", "35"];

我想将它们转换成一个对象，就像下面这样

obj=[
{name:'jhon',age:'21'},
{name:'doe', age:'22'},
{name:'alex', age:'35'}
]

我如何在 javascript 中做到这一点？

Answer 1

   ar1 = ["jhon", "doe", "alex"];
   ar2 = ["21", "22", "35"];
let obj = function objMaker(ar1,ar2){let arr = []; ar1.map((item,index) => {let obj ={};obj['name']=item; obj['age']=ar2[index];arr.push(obj);}); console.log(arr);return arr;}(ar1,ar2);

Answer 2

您可以使用地图功能：

var arr1 = ["jhon", "doe", "alex"];;
var arr2 = ["21", "22", "35"];

const obj = arr1.map((item, index) => {
  return {
   name: item,
   age: arr2[index]
  }
})

关于map函数，只是为了清理代码，可以使用隐式返回：

const obj = arr1.map((item, index) => ({
  name: item,
  age: arr2[index]
 })
)

Answer 3

你基本上可以使用map函数如下。

    var arr1 = ["jhon", "doe", "alex"];;
    var arr2 = ["21", "22", "35"];

    var combined = arr1.map(function(item, index) {
        return {name: item, age: arr2[index]};
    });
