How add record to json jquery?

Question

I have json schema:

var data_json   {
"protocol": {
    "protocol_descr": {
        "protocol_name": "test"
    },
    "protocol_body": {
        "group": {
            "group_name": "test group",
            "position_info": {
                "position_name": "1",
                "position_type": "tags",
                "position_value": "some,value",
                "data-free":"false",
                "data-type":"false",
                "data-optional":"false"
            }
        }
    }
}
}

How add one more group to "protocol_body" ? I try to use next construction - data_json.protocol.protocol_body.push(), but it's not work.

first, you need to make an array to protocol_body then only you can keep more than one group information inside that — nitishk72

To be able to use .push(), at least one of the Objects needs to be wrapped or replaced by an Array (Javascript Object push() function). Or, you'll need to assign a different key than the "group" already in place (How can I add a key/value pair to a JavaScript object?). — Jonathan Lonowski

You can directly assign object with assigning value object to key value of json object

Check below working snippet

var data_json  = {
"protocol": {
    "protocol_descr": {
        "protocol_name": "test"
    },
    "protocol_body": {
        "group": {
            "group_name": "test group",
            "position_info": {
                "position_name": "1",
                "position_type": "tags",
                "position_value": "some,value",
                "data-free":"false",
                "data-type":"false",
                "data-optional":"false"
            }
        }
    }
}
}
data_json.protocol.protocol_body.grop2 = {
  "group_name": "test group",
        "position_info": {
            "position_name": "1",
            "position_type": "tags",
            "position_value": "some,value",
            "data-free":"false",
            "data-type":"false",
            "data-optional":"false"
        }
}
console.log(data_json);

You should change the group property to array type instead of object so that you can push more groups in that property. Something like this:

var data_json = {
  "protocol": {
      "protocol_descr": {
        "protocol_name": "test"
      },
      "protocol_body": {
        "group": [{
            "group_name": "test group",
            "position_info": {
                "position_name": "1",
                "position_type": "tags",
                "position_value": "some,value",
                "data-free":"false",
                "data-type":"false",
                "data-optional":"false"
            }
        }]
    }
  }
};

var newGroup = {
   "group_name": "test group2",
    "position_info": {
        "position_name": "2",
        "position_type": "tags2",
        "position_value": "some,value",
        "data-free":"false",
        "data-type":"false",
        "data-optional":"false"
    }
};

data_json.protocol.protocol_body.group.push(newGroup);
console.log(data_json);

in your data "protocol_body" is not an array thats a reason it doesn't support push. you can use this.

data_json.protocol.protocol_body["Group2"]={"New Group":{"group_name": "test group2"}}
