Question

What is the best way to restructure Json with Angularjs or Jquery..

I am getting a json with following format

    [
  {
     "address":"balh",
     "lat":123,
     "long":456
  },
  {
     "address":"balh",
     "lat":321,
     "long":543
  },
  {
     "address":"balh",
     "lat":432,
     "long":333
  },
  {
     "address":"balh",
     "lat":123,
     "long":456
  },
  {
     "address":"balh",
     "lat":321,
     "long":543
  },
  {
     "address":"balh",
     "lat":432,
     "long":333
  }
]

The format I need is to group it with three like following..

    {
   "1":[
      {
         "address":"balh",
         "lat":123,
         "long":456
      },
      {
         "address":"balh",
         "lat":321,
         "long":543
      },
      {
         "address":"balh",
         "lat":432,
         "long":333
      }
   ],
   "2":[
      {
         "address":"balh",
         "lat":123,
         "long":456
      },
      {
         "address":"balh",
         "lat":321,
         "long":543
      },
      {
         "address":"balh",
         "lat":432,
         "long":333
      }
   ]
}

This seems more like a straight JavaScript question to me.

The code below should take your array and break it into a dictionary of arrays with three (or less) objects each:

var yourArray = [/*whatever it is in here*/];

var output = {};

for(var i = 0, c = 1, current = null; i < yourArray.length; i++) {
    if(i % 3 == 0) {
        output[c++] = current = [];
    }
    current.push(yourArray[i]);
}

Here’s a fiddle (using Angular) demonstrating before and after output
