How to parse JSON (infotable) element names via JavaScript

To pull the object names out of a JSON object, iterate through the JSON object and display the value at each index location

• Example:

  var myJson = {
  "element1": "hello",
  "element2": 12,
  "element3": true,
  "element4": {
      "subelement1": "one",
      "sebelement2": 2
  }};
   
  for (var el in myJson) {
      console.log("Element name: " + el + ", element value:" + myJson[el] + ", element type: " + typeof(myJson[el]));
  }

JSON array

• Example:
  var propertiesPort = ['port1', 'port2', 'port3', 'port4', 'port5', 'port6', 'port7', 'port8', 'port9', 'port10', 'port11', 'port12' ];
  for(var i = 0; i<propertiesPort .length; i++){
                  var portName = propertiesPort [i];
  }
  
  hoặc:
  for each (row in thingList.rows) { 
      //Now each row is already assigned to the row variable in the loop
      var thingName = row.name;
  }
