Suppose i have this object

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

which i can access like below

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

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"
                }
            }

The object["property"] syntax is meant to access an object properties and doesn't have anything to do with the syntax for object creation. If you want to access an object several levels down, follow the example below:

var basket = {
    box: { 
          mobilePhone: "mobilePhone"
         }
}

To access mobilePhone property of basket you would use: basket.box.mobilePhone or basket["box"]["mobilePhone"]

You can't use JSON syntax with a dynamic key.

You have many solutions :

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

or

var detailObj = {};
var detailObjNAME = (detailObj[io.NAME] = {});
var detailObjCODE = (detailObjName[io.CODE] = {});
detailObjCODE[io.OWN] = "12";

or

var detailObj = {};
((detailObj[io.NAME] = {})[io.CODE] = {})[io.OWN] = "12";

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

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

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";

If that is what you are getting, the you must not have defined io.
