I am having an issue, I am receiving from an external API that I don't have control a JSON message like below:

I have the restriction to be using DOJO-AJAX and CORS to send and receive the message but for some reason it comes as a plain string where I can't loop in this object using the code below:
renderReply : function(reply, textStatus, jqXHR) { var pois = new MQA.ShapeCollection(); var html = 'IDNAMEADDRESSZIPCATEGORYDISTANCE (miles)';
var jsonObj = dojo.toJson(reply);
// add POI markers and populate the search result table
for (i = 0; i < reply.length; i++) {
var result = reply[i];
As you can see I already tried to convert it with toJson but for some reason is worst is adding \ to the message and in reply[i] the first object is " " " quotes. I already tried accessing to the child with reply.searchResults but it says undefined object.
Thanks
I'm not sure there's enough context here to give an ideal answer, but I would immediately point out that that string is already JSON, so dojo.toJson is stringifying what's already stringified. You'd want dojo.fromJson (or, preferably, dojo/json.parse in newer versions of Dojo).
I would also point out that once you have this JSON string parsed, you presumably want to iterate over the searchResults property in the parsed object, not the object itself.
require(['dojo/json', ...], function(JSON, ...) {
// Assuming `reply` contains the string:
var replyObj = JSON.parse(reply);
var results = replyObj.searchResults;
for (var i = 0, l = results.length; i++) {
// Do something with results[i]
}
});
