谷歌的地理编码是晚期（还是一个落后一步）(Google geocode is late (still

我把我的有完整的代码。试图确定位置的地址。我的脚本应该创建仍与地理编码地址（在控制台 - 可变kktina）一个标志。

但不幸的是，没有一切就OK了。因为剧本还在解决以前的位置（或需要以前的坐标，说不上来）。也许有在代码中的错误，但我不能这样做了..

因此，寻求帮助，谢谢！

你可以这样做：

  function geocodePosition(pos) {
    geocoder.geocode({
      latLng: pos
    }, function(responses) {
      if (responses && responses.length > 0) {
        address = responses[0].formatted_address;
      } else {
        address = 'Cannot determine address at this location.';
      }
    });
    return address;
  }

该地址解析器是异步的，则返回时，地址的值是不确定的。

使用返回的数据的回调函数来代替，像这样（未测试）内：

var kktina = null;
function geocodePosition(pos) {
  geocoder.geocode({
    latLng: pos
  }, function(responses) {
    if (responses && responses.length > 0) {
      kktina = responses[0].formatted_address;
    } else {
      kktina = 'Cannot determine address at this location.';
    }
   console.log(kktina);
    var marker = new google.maps.Marker({
      position: point,
      draggable: true
    });
    markers.push(marker)
    marker.setMap(map);
  });
}
