Question

我有一个像这样的JSON对象，我想用邮递员中的键和值访问列表数组元素。

{
    "data": {
        "total": 1,
        "list": [
            {
                "id": 53,
                "name": "Sonu",
                "mobileNo": "6543213456",
                "address": "Greeny Pathway",
                "city": "NewYork",
                "mode": "Weekly",
                "duration": "15",
                "qty": null

            }
        ]
    },
    "success": true,
    "message": ""
}

如何在Javascript中将其作为键和值分开

Key:   id,name,mobileNo,address,city,..
Value: 53,Sonu,6543213456,Greeny Pathway,NewYork,....

Answer 1

您可以使用以下代码：

const keys = Object.keys(jsonObject);
const values = Object.values(jsonObject);

但是您的JSON对象很深，您应该将其展平，然后使用keys中的values和Object将它们分开。

Answer 2

您可以在数组中分别使用键和值。

var a = {
    "data": {
        "total": 1,
        "list": [
            {
                "id": 53,
                "name": "Sonu",
                "mobileNo": "6543213456",
                "address": "Greeny Pathway",
                "city": "NewYork",
                "mode": "Weekly",
                "duration": "15",
                "qty": null,

            }
        ]
    },
    "success": true,
    "message": ""
}

var keyval = Object.keys(a.data.list[0])
console.log(keyval)
var values = Object.values(a.data.list[0])
console.log(values)

Answer 3

JSON对象是键值对，您无法根据需要获取对象形式的键和值，但是可以从此代码中以数组的形式获取键和值

var key = []
var values = []
list.map(function(l){  keys = Object.getOwnPropertyNames(l); 
keys.map(function(key) {values.push(l[key]);})})

Answer 4

首先从第"qty": null,行中删除逗号，否则将导致json解析错误。

var resultJSON = `{
    "data": {
        "total": 1,
        "list": [
            {
                "id": 53,
                "name": "Sonu",
                "mobileNo": "6543213456",
                "address": "Greeny Pathway",
                "city": "NewYork",
                "mode": "Weekly",
                "duration": "15",
                "qty": null

            }
        ]
    },
    "success": true,
    "message": ""
}`;


var result = $.parseJSON(resultJSON);

var myList = result.data.list[0];

$.each(myList, function(k, v) {
    //display the key and value pair
    alert(k + ' is ' + v);
});

Answer 5

最后这对我有用！（用邮递员脚本）

var resdata = JSON.parse(responseBody);
console.log(resdata);

key = Object.keys(resdata.data.list[0]);
console.log(key);

value =Object.keys(resdata.data.list[0]);
console.log(value);
