Google Maps Api v3 - 地图上的错误位置图加载

Question

我的网站上需要谷歌地图API的帮助。我将地图包含在我的网站中，然后自动绘制我的位置或找到我，但问题是它给了我错误的位置，但有些位置是正确的。

这是我的网站：http://webserver.site88.net/beta-test

这是mycode：

<script type="text/javascript">
function writeAddressName(latLng) {
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({
      "location": latLng
    },
    function(results, status) {
      if (status == google.maps.GeocoderStatus.OK)
        document.getElementById("address").value = results[0].formatted_address;
      else
        document.getElementById("error").innerHTML += "Unable to retrieve your address" + "<br />";
    });
  }

  function geolocationSuccess(position) {
    var userLatLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
    document.getElementById("inLat").value = position.coords.latitude;
    document.getElementById("inLong").value = position.coords.longitude;

    // Write the formatted address
    writeAddressName(userLatLng);

    var myOptions = {
      zoom : 16,
      center : userLatLng,
      mapTypeId : google.maps.MapTypeId.ROADMAP,
      location_type: google.maps.GeocoderLocationType.ROOFTOP
    };
    // Draw the map
    var mapObject = new google.maps.Map(document.getElementById("map"), myOptions);
    // Place the marker
    var marker = new google.maps.Marker({
      map: mapObject,
      position: userLatLng
    });

    var infowindow = new google.maps.InfoWindow({
    content: '<div>'+'<b>'+'You are here '+'</b>'+'</div>'
    });


    infowindow.open(mapObject,marker);

    google.maps.event.addDomListener(window, 'load', geolocateUser);
  }

  function geolocationError(positionError) {
    document.getElementById("error").innerHTML += "Error: " + positionError.message + "<br />";
  }

  function geolocateUser() {
    // If the browser supports the Geolocation API
    if (navigator.geolocation)
    {
      var positionOptions = {
        enableHighAccuracy: true,
        timeout: 10 * 1000 // 10 seconds
      };
      navigator.geolocation.getCurrentPosition(geolocationSuccess, geolocationError, positionOptions);
    }
    else
      document.getElementById("error").innerHTML += "Your browser doesn't support the Geolocation API";


}
