1. features is an array. Arrays are not iterated over using 'for..in' in
javascript, instead:

  for (var i = 0; i < features.length; i++) {
    alert(features[i]);
  }

2. var feature in features syntx gives an index, not the object:

  for (var feature in features) {
    alert(features[feature]);
  }
