Array inside of Json

Question

How to have object inside of an Array and Iterate to access Objects one by one. Please help to solve this.

var mainVals = [{id:1,value:[{},{}]},{id:2,value:[{},{}]}];
var hubVals  = [{id:1,value:[{},{}]},{id:2,value:[{},{}]}];

var posit = {1:mainVals,2:hubVals};

  for (var i = 1;i <= 2;i++)
         {
             var obj = posit.i;       
             alert("obj:"+obj); // which gives undefined
         }

use bracket notation: posit[i]

You need to use square-bracket notation when the property you're wanting to read is dynamic:

var obj = posit[i];

The correct code should be something like this, since you have two arrays inside of each other:

var mainVals = [{id:1,value:[{},{}]},{id:2,value:[{},{}]}];
var hubVals  = [{id:1,value:[{},{}]},{id:2,value:[{},{}]}];
var posit = {1:mainVals,2:hubVals};

for (var i = 1;i <= 2;i++)
     { 
        for(var j = 0; j <= 1; ++j){
           var obj = posit[i][j];       
           alert("obj:"+obj); 
        }
     }
