Question

大家好，我最近玩的是Google Maps＆amp;我必须为学校做的项目的地方。我可以很好地加载页面，并且建议的位置也很好。但是如果你点击建议的位置，有时会发生溃败正在朝着一个完全不同的城镇/城市运行。只有当您通过Google Places API点击建议的地点时才会感觉到这种情况，而不是只是简单地写下该地点。

我使用的代码很多来自谷歌的itselfe，但我仍然会发布它，以防我复制错误：在这里我加载goolel api：

  <script type="text/javascript"
  src="http://maps.googleapis.com/maps/api/js?key=AIzaSyCr0wsx4a5_o03hPTpC_CtRARjzCnOEGX4&sensor=false&libraries=places">
</script>

这是加载地图（初始化），计算路线（calcRoute）并加载谷歌地方的脚本：

    <script>
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;

function initialize() {
 var styles = [{"featureType":"water","elementType":"all","stylers":[{"hue":"#76aee3"},{"saturation":38},{"lightness":-11},{"visibility":"on"}]},{"featureType":"road.highway","elementType":"all","stylers":[{"hue":"#8dc749"},{"saturation":-47},{"lightness":-17},{"visibility":"on"}]},{"featureType":"poi.park","elementType":"all","stylers":[{"hue":"#c6e3a4"},{"saturation":17},{"lightness":-2},{"visibility":"on"}]},{"featureType":"road.arterial","elementType":"all","stylers":[{"hue":"#cccccc"},{"saturation":-100},{"lightness":13},{"visibility":"on"}]},{"featureType":"administrative.land_parcel","elementType":"all","stylers":[{"hue":"#5f5855"},{"saturation":6},{"lightness":-31},{"visibility":"on"}]},{"featureType":"road.local","elementType":"all","stylers":[{"hue":"#ffffff"},{"saturation":-100},{"lightness":100},{"visibility":"simplified"}]},{"featureType":"water","elementType":"all","stylers":[]}];
 var styledMap = new google.maps.StyledMapType(styles, {name: ""});

  directionsDisplay = new google.maps.DirectionsRenderer({polylineOptions: {
      strokeColor: "red"
    }});
  var mapOptions = {
          center: new google.maps.LatLng(47.6826215,13.0984208,17),
          zoom: 15,
          disableDefaultUI: true,
          mapTypeControlOptions: {
            mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'map_style']
            }
        };
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
        map.mapTypes.set('map_style', styledMap);
        map.setMapTypeId('map_style');
        map.setOptions({styles: styles});

    var defaultBounds = new google.maps.LatLngBounds(
          new google.maps.LatLng(47.67052,13.114028),
          new google.maps.LatLng(47.6910273,13.1153865));
        var options = {
          bounds: defaultBounds,
        };

        var start_input = document.getElementById('start');
        start_autocomplete = new google.maps.places.Autocomplete(start_input, options);
    var end_input = document.getElementById('end');
        end_autocomplete = new google.maps.places.Autocomplete(end_input, options);

  directionsDisplay.setMap(map);
}

function calcRoute() {
  var start = document.getElementById('start').value;
  var end = document.getElementById('end').value;
  var request = {
      origin:start,
      destination:end,
      travelMode: google.maps.TravelMode.DRIVING
  };
  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
    }
  });
}

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

    </script>

Google Places API会返回错误的坐标
