retrieve the JSON of nested objects in js

Question

I have built a web service using java, and the return value is a parsed object to JSON.

the problem is that I have an object that contains a Hashmap<> in it as a parameter, when I parse it to JSON and returns it, How could I handle it in js, how could I get the values of the hashmap.

Here is the object that I parse to JSON.

Object human;

Hashmap<String, String> properties;

properties.put("property1", "value");
properties.put("property2", "value");
properties.put("property3", "value");

/* here where I got the object that contains several attributes  beside the hashmap that is considered as object*/

human.setProperties(properties);

return aGson.toJson(human);

You seem to be confusing Java and JavaScript. They are entirely different. Please review your question and tag it appropriately. — Rory McCrossan

@rory-mccrossan no no, I built a web service using java, but the return value is JSON and I should handle it with js — hasan.alkhatib

@HasanKhatib We'll need to know how you're passing this to JavaScript. — James M

@JamesMcLaughlin I used an ajax request to get the json from this service that I built, now I want to fill the html with this json — hasan.alkhatib

Once you've received your JSON text from the web service, parse it in JavaScript as

var human = JSON.parse( jsonTextFromWS );
console.log( human.properties.property1 ); // value

Use the org.json.JSONObject class, like this:

JSONObject jsonHuman = new JSONObject( human );

It should use reflection to find all the public fields and build a valid JSON object for you.
