How to convert JSON Object into Javascript array

Question

Linked to this question and this one also, I would like to know how to do the exact same thing but with a different type of JSON :

Here my JSON Object :

var myDb = {
    "04c85ccab52880": {
        "name": "name1",
        "firstname": "fname1",
        "societe": "soc1"
    },
    "04c95ccab52880": {
        "name": "name2",
        "firstname": "fname2",
        "societe": "soc2"
    },
    "048574220e2a80": {
        "name": "name3",
        "firstname": "fname3",
        "societe": "soc3"
     }
};

My problem is that my JSON is different from their JSON, actually I have an array of array in mine. So how to convert this into a Javascript array ?

var arr = [];

$.each( myDb, function( key, value ) {
    arr.push( value );    
});

console.log(user_list);

This kind of script seems to return my 3 different objects but where are my uid from JSON ? How can I get them ? Because now my keys are 0,1,2 and no longer my uid.

Any ideas ? Thanks

A working JSFIDDLE

JS code:

//var arr = [];
var myDb = {
    "04c85ccab52880": {
        "name": "name1",
        "firstname": "fname1",
        "societe": "soc1"
    },
    "04c95ccab52880": {
        "name": "name2",
        "firstname": "fname2",
        "societe": "soc2"
    },
    "048574220e2a80": {
        "name": "name3",
        "firstname": "fname3",
        "societe": "soc3"
     }
};

$.each( myDb, function( key, value ) {
    //arr.push( value );    
    console.log("key => "+key);//will output: 04c85ccab52880 and all such
    $.each( value, function( ky, val ) {
        console.log('ky => '+ky);//will output: name, firstname, societe
        console.log('val => '+val);//will output: name1, fname1, soc1
    });    
});

if you want to convert them, with key. I suggest something like below

var mapped = Object.keys( myDb  ).map(function( uid ){
    return (myDb[uid ].uid = uid ) && myDb[uid ];
});

for value in your array look like, example mapped[0] has value :

{
    "name": "name1",
    "firstname": "fname1",
    "societe": "soc1",
    "uid": "04c85ccab52880"
}

Thanks, how can I specifically get the value of uid this way ? `mapped[0]` will return the whole object, but if I only need the uid for example ? Would `mapped[0]['uid']` work in your opinion ? – hacks4life Jun 19 '14 at 13:05
