从数组中分割数据并存储在变量中（Javascript/JSON）

我有一个需求，需要对传入数据进行分区，使其看起来像以下示例：

//required payload

{
"campaign_id": "",
"recipient": {
    "first_name": "",
    "last_name": "",
    "company": "",
    "email": "",
    "address_1": "",
    "city": "",
    "state": "",
    "postal_code": "",
    "identifier": ""
}
}

但是，我的问题是当前发布到我的端点的有效负载如下所示：

//entire payload

"body": {
"info": [
{
"campaign_id": "",
"recipient": {
    "first_name": "",
    "last_name": "",
    "company": "",
    "email": "",
    "address_1": "",
    "city": "",
    "state": "",
    "postal_code": "",
    "identifier": ""
}
}
],
"otherArray": [],
"otherString": "",
"otherString2": ""
}
} 

我想做的是从第二个示例中提取第一个示例中所需的数据，然后将其存储在变量中。如下所示：

var requiredPayload = {"campaign_id": "", "recipient": {}};

如何将活动id+收件人对象放入单个变量中？

我们应该能够将info数组的第一个元素分配给所需的有效负载变量，如下所示：

常数有效载荷={
“正文”：{
“信息”：[
{
“活动id”：“，
“收件人”：{
“名字”：“，
“姓氏”：“，
“公司”：“，
“电子邮件”：“，
“地址1”：“地址”，
“城市”：“，
“国家”：“，
“邮政编码”：“，
“标识符”：”
}
}
],
“其他数组”：[]，
“其他字符串”：“，
“其他字符串2”：”
}
};
var requiredPayload=payload.body.info[0]；
log（“requiredPayload:”，requiredPayload）我们应该能够将info数组的第一个元素分配给requiredPayload变量，如下所示：



常数有效载荷={
“正文”：{
“信息”：[
{
“活动id”：“，
“收件人”：{
“名字”：“，
“姓氏”：“，
“公司”：“，
“电子邮件”：“，
“地址1”：“地址”，
“城市”：“，
“国家”：“，
“邮政编码”：“，
“标识符”：”
}
}
],
“其他数组”：[]，
“其他字符串”：“，
“其他字符串2”：”
}
};
var requiredPayload=payload.body.info[0]；
log（“requiredPayload:”，requiredPayload）请尝试以下操作：

    var data={"body": {
        "info": [
        {
        "campaign_id": "",
        "recipient": {
            "first_name": "",
            "last_name": "",
            "company": "",
            "email": "",
            "address_1": "",
            "city": "",
            "state": "",
            "postal_code": "",
            "identifier": ""
        }
        }
        ],
        "otherArray": [],
        "otherString": "",
        "otherString2": ""
        }
        };
    console.log(data.body.info[0]); //data is variable name
var info_data=data.body.info[0];

如果信息有多个活动标识，请尝试此操作

$.each(data.body.info, function (indexInArray, valueOfElement) { 
    console.log(data.body.info[indexInArray]);
});

试试这个：

    var data={"body": {
        "info": [
        {
        "campaign_id": "",
        "recipient": {
            "first_name": "",
            "last_name": "",
            "company": "",
            "email": "",
            "address_1": "",
            "city": "",
            "state": "",
            "postal_code": "",
            "identifier": ""
        }
        }
        ],
        "otherArray": [],
        "otherString": "",
        "otherString2": ""
        }
        };
    console.log(data.body.info[0]); //data is variable name
var info_data=data.body.info[0];

如果信息有多个活动标识，请尝试此操作

$.each(data.body.info, function (indexInArray, valueOfElement) { 
    console.log(data.body.info[indexInArray]);
});
