How to change nested object into array

Question

I have a object like this.

var Obj = {
    obj1 : {
        val : 1,
        id : 1
    }
    obj2 : {
        val : 2,
        id :2
    }
    obj3 : {
        val : 3,
        id :3
    }
}

I want my obj1and all sub object into one array so I can retrieve the value. I want array in array because I want to retrieve them, Since it is dynamic I can not use Obj.obj1 therefore I want to push into array.

Can Anybody tell How Can I get that. Thanks for help

What have you tried? It's also unclear what you want the output to look like. Do you want the output to just be [1, 2, 3]? — castletheperson

Use Object.keys and Array#map methods to convert it to an array but the order is not guaranteed since object properties don't have any order.

var Obj = {
  obj1: {
    val: 1,
    id: 1
  },
  obj2: {
    val: 2,
    id: 2
  },
  obj3: {
    val: 3,
    id: 3
  }
};

var res = Object.keys(Obj).map(function(k) {
    return Obj[k];
  })

console.log(res);

Object.values(Obj) is another option (though browser support is lower)

@4castle : It's not widely supported

@4castle That works fine, But any suggestion how to delete this record from the object. eg : if(arr[I].val = 1) then I want to delete Obj1 mean respective object from the main object.

@David : use delete keyword
