这里的问题非常简单，我有以下变量。设置格式如下 {商品编号:数量，商品编号，数量...}

var x = {4214061251:1,2497227651:2,4214140739:2};

我的问题只是如何正确循环以访问每个元素。

我希望能够分别访问商品编号和数量，如何实现这一点？

Answer 1

var x = {4214061251:1,2497227651:2,4214140739:2};

// Array of all keys 4214061251, 2497227651 ...
var keysArr = Object.keys(x);
console.log(keysArr);

// Iterate on keys
keysArr.forEach(
  (el) => {
    // To access keys
    console.log("Key: "+el);
    
    // To access values instead
    console.log("Value: "+x[el]);
  }
)
