Coverting json array to js objects

I have a json string like this

[ { 
"name":"sourabh", 
"userid":"soruabhbajaj", 
"id":"11", 
"has_profile_image":"0" }, 
{
开发者_JAVA百科"name":"sourabh", 
"userid":"sourabhbajaj", 
"id":"12", 
"has_profile_image":"0" 
}]

Now, I want to convert this json array to the string like this so that I can access any object using its id on the entire page.

{ "11": { 
"name":"sourabh", 
"userid":"soruabhbajaj", 
"id":"11", 
"has_profile_image":"0" }, 
"12": {
"name":"sourabh", 
"userid":"sourabhbajaj", 
"id":"12", 
"has_profile_image":"0" 
}}

Suggest some code please. Thanx in advance

EDIT: Will this work:

user.(function(){return id;})

And then accessing objects like this

user.id.name

I mean is this a correct way of defining object?

var data = ... the initial array
var result = {};
for (var i = 0; i < data.length; i++) {
    var element = data[i];
    result[element.id] = element;
};

var data = [ 
    {"name":"sourabh", "userid":"soruabhbajaj", "id":"11", "has_profile_image":"0"}, 
    {"name":"sourabh", "userid":"sourabhbajaj", "id":"12", "has_profile_image":"0"}
];

var newData = {};

for (var i = 0; i < data.length; i++) {
    var item = data[i];
    newData[item.id] = item;
}

Now newData is an object where the keys are the ids of the people and the data for each key is the person object itself. So, you can access an item like this:

var id = "11";
var name = newData[id].name;
