Tips on formatting JSON objects that contain fields with their own object types?

Question

Tips on formatting JSON objects that contain fields with their own object types?

UPDATE: I've tried something similar to this, but it's not working. I believe there lies the issue

var stringifyObj = JSON.stringify({
      "addressAddressId":$('#address').val(){ 
          "cityId:"$('#city').val(){
                "postalCode":$('#postalCode').val() 
           } 
      }
});

*When I create a test client in Netbeans, the JSON structure (GET/JSON) looks like this. How can I implement this using JavaScript and the Stringify function? *

    "addressAddressId": {
        "addressId": 1,
        "address": "Railway Street 2",
        "address2": null,
        "district": null,
        "postalCode": "20360",
        "phone": null,
        "coordinates": null,
        "latitude": null,
        "longitude": null,
        "directions": null,
        "description": null,
        "addrZipCityCountry": null,
        "lastUpdated": 1361754860000,
        "cityId": {
            "cityId": 1,
            "city": "",
            "lastUpdate": 1361754850000,
            "countryCountryId": {
                "countryId": 1,
                "country": "Sweden",
                "lastUpdate": 1361754837000
            }
        }
    },

What is the correct syntax for using JSON.stringify with custom object types such as City-object within Address-object?
Do I need to include every field in the JSON if I'm not using @JsonIgnoreProperties({""})? I only require address, city, and postal code. Address is of type Address with a string address field on the server side, while City is of type City containing a string field for city name, etc.

Answer №1

Uncertain of your intentions with the Javascript function provided above, but if you aim to generate JSON in a similar structure using Javascript, consider this approach :

var stringifyObj = JSON.stringify({
  "addressAddressId": {
    "addressId": 1,
    "address": "Järnvägen 2",
    "address2": null,
    "district": null,
    "postalCode": "20360",
    "phone": null,
    "coordinates": null,
    "latitude": null,
    "longitude": null,
    "directions": null,
    "description": null,
    "addrZipCityCountry": null,
    "lastUpdated": 1361754860000,
    "cityId": {
        "cityId": 1,
        "city": "",
        "lastUpdate": 1361754850000,
        "countryCountryId": {
            "countryId": 1,
            "country": "Sweden",
            "lastUpdate": 1361754837000
        }
    }
  }         
});

The essential step is enclosing the JSON string as a parameter for JSON.stringify.

If constructing the object gradually is needed, rather than supplying all properties at once as shown above, consider this alternative :

var obj = {};
//add properties as required
//basic properties
obj.addressId = 1;
obj.address = "Järnvägen 2";
obj.address2 = null;
//nested properties
obj.cityId = {};
obj.cityId.cityId = 1;
obj.cityId.countryCountryId = {};
obj.cityId.countryCountryId.countryId = 1;

Once all object properties are filled appropriately, utilize JSON.stringify like so :

var stringifyObj = JSON.stringify(obj);

To achieve the JSON format depicted in your example, further encompass the obj variable like this :

var stringifyObj = JSON.stringify({ addressAddressId = obj });

Hoping the concept is clear :)

There appears to be a missing comma at this point, however, it may not necessarily be the cause of the issue.

"postalCode": {
    "postalCode": $('#postalCode').val()
} <--- a comma is required at this location

"addressAddressId": {
