从简单对象创建javascript对象 [英] Creating javascript object from simple object

问题描述

假设我有这个对象

var io={"NAME":"Battery For Alarm Panel","CODE":"POWER MAX","OWN":"ONM"}

我可以像下面那样访问

 io['NAME'] or io['CODE'] etc.

但是如果想创建另一个对象，那么我如何访问 obj 就像下面的代码不工作，错误 Uncaught SyntaxError: Unexpected token [

But if want to create another object then how i can access obj like below code is not working with error Uncaught SyntaxError: Unexpected token [

       detailObj=
        {
            io['NAME']:
            {
                io['CODE']:
                {
                    io['OWN']:"12"
                }
            }
        }

我需要在 io 对象中进行哪些更改以创建 detailObj

What changes i need to made in io object to create detailObj

推荐答案

你不能像这样声明一个对象，在属性名称的对象声明中使用变量.您必须像这样创建对象:

You can't declare an object like that, using variables inside of the object declaration for the property names. You'll have to create the object like this:

detailObj = {};
detailObj[io['NAME']] = {};
detailObj[io['NAME']][io['CODE']] = {};
detailObj[io['NAME']][io['CODE']][io['OWN']] = "12";
