Could any one ask this question on StackFlow

As you may suppose, I'm using a local server to request the sensors from a cloud server. The getSensor() method returns this JSON file shown below. You may create a sample of this.

This is the array of sensors in JSON format:

{ "contextResponses": [4] 0: { "contextElement": { "type": "StreetFixed" "isPattern": "false" "id": "StreetFixed1" "attributes": [4] 0:   { "name": "aircondition" "type": "float" "value": "66.1" }- 1:   { "name": "lat" "type": "float" "value": "-1.4519538" }- 2:   { "name": "lng" "type": "float" "value": "-48.4781193" }- 3:   { "name": "temperature" "type": "float" "value": "29.8" }- - }- "statusCode":  { "code": "200" "reasonPhrase": "OK" }- }- 1:   { "contextElement":  { "type": "StreetFixed" "isPattern": "false" "id": "StreetFixed2" "attributes": [4] 0:   { "name": "aircondition" "type": "float" "value": "66.1" }- 1:   { "name": "lat" "type": "float" "value": "-1.4519062" }- 2:   { "name": "lng" "type": "float" "value": "-48.476207" }- 3:   { "name": "temperature" "type": "float" "value": "29.8" }- - }- "statusCode":  { "code": "200" "reasonPhrase": "OK" }- }- 2:   { "contextElement":  { "type": "StreetFixed" "isPattern": "false" "id": "StreetFixed3" "attributes": [4] 0:   { "name": "aircondition" "type": "float" "value": "66.1" }- 1:   { "name": "lat" "type": "float" "value": "-1.4518047" }- 2:   { "name": "lng" "type": "float" "value": "-48.4744374" }- 3:   { "name": "temperature" "type": "float" "value": "29.8" }- - }- "statusCode":  { "code": "200" "reasonPhrase": "OK" }- }- 3:   { "contextElement":  { "type": "StreetFixed" "isPattern": "false" "id": "StreetFixed4" "attributes": [4] 0:   { "name": "aircondition" "type": "float" "value": "66.1" }- 1:   { "name": "lat" "type": "float" "value": "-1.4517104" }- 2:   { "name": "lng" "type": "float" "value": "-48.4726244" }- 3:   { "name": "temperature" "type": "float" "value": "29.8" }- - }- "statusCode":  { "code": "200" "reasonPhrase": "OK" }- }- - }

Here is the uncomment code as requested:

function getSensors(){      var result;      var request = new XMLHttpRequest();      request.open('GET', '/getSensors', false);   if (request.status === 200)         {   result = JSON.parse(request.responseText).contextResponses;    console.log(result);    console.log("getSensors done!"); } return result; }

Thanks!

Pedro,

What does your sensor data look like? As I do not have access to your sensor service I need to replicate the data to test your app. Can you un-comment the console.log(result) and copy that data and post for me?

Pedro,

Are you clearing the maps graphics in your code some where? Maybe it would be good to post your whole modified code.
