  var currentLocation = marker.getPosition();
  var geocoder  = new google.maps.Geocoder();        
  var location  = new google.maps.LatLng(currentLocation.lat(), currentLocation.lng());

  geocoder.geocode({ 'latLng': location , function (results, status) {
    if (status == google.maps.GeocoderStatus.OK) { 
      var add = results[0].address_components[1][1];
      document.getElementById('lat').value = add;

Try this:

<input id="postal_code"/>
<input id="street"/>
...

script

if (status == google.maps.GeocoderStatus.OK) {
for(var i in results[0].address_components) {
  // skip items with no types 
  if(typeof results[0].address_components[i].types == 'undefined') {
    continue;
  }

  if(results[0].address_components[i].types.indexOf('postal_code') > -1) {
    document.getElementById('postal_code').value = results[0].address_components[i].long_name;
  }
  if(results[0].address_components[i].types.indexOf('street') > -1) {
    document.getElementById('street').value = results[0].address_components[i].long_name;
  }
  ...
}
}
