在nodejs

Question

var resobj = {
    "status": {
        "code": 2000,
        "message": "Success"
    },
    "order": {
        "Shop": 1,
        "Quantity": 1,
        "Customer": 1 
    }
}

我有这个json，我需要遍历订单并访问密钥（商店，数量，客户）。任何人都可以帮助我。

Answer 1

使用Object＃键将返回键数组

＆＃13;

var resobj = {
    "status": {
        "code": 2000,
        "message": "Success"
    },
    "order": {
        "Shop": 1,
        "Quantity": 1,
        "Customer": 1 
    }
};

Object.keys(resobj.order).forEach(key => console.log(key));

Answer 2

您正在寻找的是Object.keys [MDN]

示例：

Object.keys(resobj.order).forEach((key) => {
    console.log(key);
});
// Will log the keys "Shop", "Quantity" and "Customer"
