Object(keys) Helper Function for ExtendScript

get_keys_from_associative_array.js

  // Custom Helper function for ExtendScript (Adobe CEP) created as an alternative since JavaScript Object(keys) method does not work
  
  var getKeysWithoutObjectKeysSupport = function(associativeArrayObject) {
    var arrayWithKeys=[], associativeArrayObject;
    for (key in associativeArrayObject) {
      // Avoid returning these keys from the Associative Array that are stored in it for some reason
      if (key !== undefined && key !== "toJSONString" && key !== "parseJSON" ) {
        arrayWithKeys.push(key);
      }
    }
    return arrayWithKeys;
  }
  
  var myAssociativeArrayObject = {
    'name': 'Luke',
    'language': 'ExtendScript',
    'compatibility': 'none'
  };
  
  var keys = getKeysWithoutObjectKeysSupport(myAssociativeArrayObject);
  
  alert(keys);
  
  alert(Object.keys(myAssociativeArrayObject)); // JavaScript's Object(keys) method is supported if this works

Do you have something similar to get the values from JSON?
