javascript - 访问JavaScript中的对象问题

Question

这个问题已经有答案了:

Accessing an object property with a dynamically-computed name (19 个回答)

已关闭 5 年前。

这是我的console.log(params)的结果:

currency_id: false
customer_id: 127505
"payment[account_name]": ""
"payment[iban]": ""
"payment[method]": "adyen_sepa"
store_id: "1"

我从ajax调用中得到这个，当我这样做时onSuccess :

 console.log(params.customer_id);  // I got the right value
 console.log(params.payment['method'])  // I am getting undefined
 var obj = "payment['method']";
 console.log(params.obj)  // still undefined 

如何从 payment[method] 获取值？谢谢

Answer 1

How can I get teh value from payment[method] ? Thnx

使用括号表示法

var obj = "payment[method]";
console.log(params[obj])

演示

var params = {
  currency_id: false,
  customer_id: 127505,
  "payment[account_name]": "",
  "payment[iban]": "",
  "payment[method]": "adyen_sepa",
  store_id: "1"
}

var obj = "payment[method]";
console.log(params[obj])
