如何在没有 static 主键的情况下迭代 json？

Question

I'm trying to iterate over a json object with multiple json objects inside, but the main key who allow me to access to the objects is not static , How can I iterate over those objects and at the same time to know the main key who允许我访问 object 吗？

let res = {
     Zw== : { price: "500", code: "Zw==", name: "Word 2013", image: "path/d360f0.jpg", total: 1},
     aA== : { price: "300", code: "aA==", name: "Power point 2013", image: "path/80fa572.png", total: 1},
     xH== : { price: "300", code: "aA==", name: "Power point 2013", image: "path/80fa572.png", total: 1}
};

你的 object 属性看起来坏了，所以我会调查一下。

我认为您正在寻找的是Object.keys ..

例子：

function printKeys(obj) {
    console.log(Object.keys(obj));
}

你可以传入你的res object，它会给你 object 的属性键。

从那里您可以使用该属性作为下一个键。

printKeys(res['Zw']);
