将两个数组转换为 JSON 对象

Question

我正在尝试从两个数组构建 JSON。一个数组包含 field_name，另一个包含对应 field_name 的 field_value

    var field_name = ["sys_id","country","calendar_integration","user_password","last_login_time"]
var field_value = ["6816f79cc0a8016401c5a33be04be441","United State","Outlook","Password1","2019-03-19 09:48:41"];

预期输出：

output = { "sys_id" : "6816f79cc0a8016401c5a33be04be441",
        "country" : "United State",
        "calendar_integration" : "Outlook",
        "user_password": "Password1",
        "last_login_time": "2019-03-19 09:48:41"
        }

任何人都可以在这里提供帮助，如何在 JavaScript 中实现这一点。

Answer 1

你可以使用reduce()来做到这一点。在索引i处设置来自field_name的值作为键，在当前索引处设置为field_value的值

var field_name = ["sys_id","country","calendar_integration","user_password","last_login_time"]
var field_value = ["6816f79cc0a8016401c5a33be04be441","United State","Outlook","Password1","2019-03-19 09:48:41"];

let res = field_name.reduce((ac,a,i) => ({...ac,[a]:field_value[i]}),{});
console.log(res);

你也可以用同样的方式使用forEach()。

var field_name = ["sys_id","country","calendar_integration","user_password","last_login_time"]
var field_value = ["6816f79cc0a8016401c5a33be04be441","United State","Outlook","Password1","2019-03-19 09:48:41"];
let obj = {};
field_name.forEach((a,i) => obj[a] = field_value[i]);
console.log(obj)

Answer 2

如果两个数组的大小始终相同，您可以尝试类似的方法：

let JSONOutput = {}

for (let i = 0; i < firstArray.length; i++) {
    JSONOutput[firstArray[i]] = secondArray[i];
}

Answer 3

检查此解决方案

var output = {};
field_name.forEach((field, index) => {
     output[field] = field_value[index];
 });
