I see a slight problem where you're assigning the value of the input
to a variable named "destination" and then referring to it later as
"destino".
I modified your code a bit to write and read the value of the data you
are storing. You should see an alert box containing a json string
representing your data, with the timestamp changing after each
request:
var destino = "Test value"
var dia = new Date().getTime();
var salvarDestino = {};
salvarDestino[dia] = destino;
var json = gadgets.json.stringify(salvarDestino);
var req = opensocial.newDataRequest();
req.add(req.newUpdatePersonAppDataRequest(
opensocial.DataRequest.PersonId.VIEWER,
'ownerDestino',
json));
req.add(req.newFetchPersonAppDataRequest(
opensocial.DataRequest.PersonId.OWNER,
'ownerDestino'), "retrieve");
req.add(req.newFetchPersonRequest(
opensocial.DataRequest.PersonId.OWNER), "me");
req.send(response);
function response(data) {
var me = data.get("me").getData();
var myData = data.get("retrieve").getData()[me.getId()]
["ownerDestino"];
alert(gadgets.util.unescapeString(myData));
};
You can gadgets.json.parse() this string to get access to a
corresponding object.
Hope this helps,
