How to group several JSON objects which contains array with same id together

Question:

Tag: jquery,arrays,json

Please help to figure out how can I group and display JSON objects. Here's my example:

var result = [
   {
    "data":
           [{
             "id": 1,
              "name": "aaa"
          }]
   },
   {
    "data": 
          [{
             "id": 2,
             "name": "bbb"
          }]
  },
  {
    "data": 
          [{
             "id": 1,
             "name": "cccc"
          }]
  },
  {
      "data": [{
          "id": 3,
          "name": "ddd"
      }]
  },
 {
     "data": [{
         "id": 2,
        "name": "eee"
     }]
}, 
 {
    "data": 
           [{
            "id": 3,
             "name": "fff"
          }]
}
]

I want to group the name which have the same id using jQuery. Hope you can help me to solve this issue. I would be very thankful for this.

Thank you in advance!


Answer:
var result = [
   {
    "data":
           [{
             "id": 1,
              "name": "aaa"
          }]
   },
   {
    "data": 
          [{
             "id": 2,
             "name": "bbb"
          }]
  },
  {
    "data": 
          [{
             "id": 1,
             "name": "cccc"
          }]
  },
  {
      "data": [{
          "id": 3,
          "name": "ddd"
      }]
  },
 {
     "data": [{
         "id": 2,
        "name": "eee"
     }]
}, 
 {
    "data": 
           [{
            "id": 3,
             "name": "fff"
          }]
}
];

var groups={};

$.each(result,function(key,val){
    $.each(val.data,function(k,v){
        var id = v.id;
        if(groups[id]){

            groups[id]['name'].push(v.name);

        }else{
            groups[id] = {};
            groups[id]['name'] = [];
            groups[id]['name'].push(v.name);
            groups[id]['id'] = v.id;
        }



    });
});

console.log(groups);
