Convert String to JSON object in GWT (JSNI)

Question

How to convert a string to a JSON object that I'll use inside JSNI? Thank you.

Answer 1

This is a copy-paste way to do it:

import com.google.gwt.core.client.JsonUtils;
import com.google.gwt.json.client.JSONArray;
import com.google.gwt.json.client.JSONObject;

...

JSONObject data = new JSONObject(JsonUtils.safeEval(jsonString));
JSONArray array = data.get("anArray").isArray();
JSONObject obj = data.get("anObject").isObject();

Answer 2

You should look at gwt core JsonUtils which has a safeEval method for the string. You should define a JavaScript Overlay Object for use with the result or you could work with the object in JSNI as you seem to want to.
