Question

我正在尝试从两个数组构建JSON。一个数组包含field_name，另一个包含对应的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帮助您，如何在JavaScript中实现这一目标。

Answer 1

您可以使用reduce()进行操作。将索引field_name的{{1}}的值设置为键，并将当前索引的值设置为i

field_value

您也可以以相同的方式使用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);。

forEach()

Answer 2

如果两个数组的大小始终相同，则可以尝试类似的操作：

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];
 });

将两个数组转换为JSON对象
