                }
            },
            "total": {
                "indexing": {
                    "index_total": 4,
                    "index_time_in_millis": 5,
                    "index_current": 0,
                    "delete_total": 0,
                    "delete_time_in_millis": 0,
                    "delete_current": 0
                }
            }
        }
    }
}

How can I select the key i.e "get56_name" as answer. I dont want the value, I want to select the key how can i get it?

what do you mean by "I don't want the value?" what will you do with the object then? — Tolga Evcimen, Sep 23 '14 at 06:09

@NitishKumar:I want get answer as get56_name and assign it to variable. I tried like this x.indices.get(0) and many things like this but none of them are working — Krishna, Sep 23 '14 at 06:15

This will return the first key in array of keys like "get56_name"

Object.keys(x["indices"])[0]

Hope this is what you are asking
