我如何console.log键的值?

Question

我如何访问和console.log()我在这里给出的键的值:

对象{USD_GBP: 0.726718}

我希望从关键美元/英镑中访问0.726718。

我正在尝试在JavaScript中执行此操作。

Answer 1

下面是一个示例，展示了读取对象中键值的几种方法:

const obj = {USD_GBP: 0.726718};
console.log(obj.USD_GBP); 
console.log(obj['USD_GBP']);
// good if you can hardcode the key.
// Maybe your key is in a variable or constant.
// In that case, you can do something like:
const runtimeKnownKey ='USD_GBP'; 
console.log(obj[runtimeKnownKey]);
