Question

我目前正在尝试在我的网页上制作多标记谷歌地图，但试图从邮政编码中获取每个标记的位置。我找到了邮政编码地理编码的标记和代码的代码，但我似乎找不到将它们粘在一起的方法。

我有多个标记代码：

  <script type="text/javascript">
  var locations = [
  ['Chester', 53.183497, -2.890605, 3, 'https://www.google.co.uk'],
  ['Manchester', 53.474103, -2.243593, 2, 'https://www.google.co.uk'],
  ['Liverpool', 53.421206, -2.945146, 1, 'https://www.google.co.uk/']
  ];


var map = new google.maps.Map(document.getElementById('map'), {
  zoom: 9,
  center: new google.maps.LatLng(53.381021, -2.608138),
  mapTypeId: google.maps.MapTypeId.TERRAIN,

});

var infowindow = new google.maps.InfoWindow();

var marker, i;

for (i = 0; i < locations.length; i++) {  
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    url: locations[i][4],
    map: map
  });

    google.maps.event.addListener(marker, 'dblclick', function() {
            window.location.href = this.url;
        });

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}
</script>

我有邮政编码地理编码代码：

  <html>
  <head>
  <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
  <script type="text/javascript"></script>
  </head>
  <body onload="initialize()">
  <div align="center" style="height: 30px; width: 530px">
  <input id="address" type="textbox">
  <input type="button" value="Geocode" onclick="codeAddress()">
  </div>
  <div id="map" style="height:200px; width: 530px"></div>
  </body>
  </html>
  <script>
  var geocoder;
  var map;
  function initialize()
  {
    geocoder = new google.maps.Geocoder();
    map = new google.maps.Map(document.getElementById("map"),
  {
    zoom: 8,
    center: new google.maps.LatLng(22.7964,79.5410),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });
  }

  function codeAddress()
  {
   var address = document.getElementById("address").value;
   geocoder.geocode( { 'address': address}, function(results, status)
   {
    if (status == google.maps.GeocoderStatus.OK)
    {
        map.setCenter(results[0].geometry.location);
        var marker = new google.maps.Marker(
        {
            map: map,
            position: results[0].geometry.location
        });
    }
    else
    {
        alert("Geocode was not successful for the following reason: " + status);
    }
  });
   }
   </script>

以下示例说明如何利用google.maps.Geocoder显示详细地址信息，包括邮政编码：

function initMap() {

    var geocoder = new google.maps.Geocoder();

    var locations = [
        ['Chester', 53.183497, -2.890605, 3, 'https://www.google.co.uk'],
        ['Manchester', 53.474103, -2.243593, 2, 'https://www.google.co.uk'],
        ['Liverpool', 53.421206, -2.945146, 1, 'https://www.google.co.uk/']
    ];


    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 9,
        center: new google.maps.LatLng(53.381021, -2.608138),
        mapTypeId: google.maps.MapTypeId.TERRAIN,

    });

    var infowindow = new google.maps.InfoWindow();


    for (var i = 0; i < locations.length; i++) {
        var latLng = { lat: locations[i][1], lng: locations[i][2] };
        resolveAddressByLatLng(geocoder, latLng, (function(loc) {

                return function(result) {
                    //console.log(location);

                    var marker = new google.maps.Marker({
                        position: new google.maps.LatLng(loc[1], loc[2]),
                        url: loc[4],
                        map: map
                    });


                    google.maps.event.addListener(marker, 'click', function() {
                        infowindow.setContent(result[0].formatted_address);
                        infowindow.open(map, marker);
                    });

                }

            })(locations[i]),
            function(status) {
                console.log("Geocode was not successful for the following reason: " + status);
            });


    }
}


function resolveAddressByLatLng(geocoder, latLng,success,error) {
    geocoder.geocode({ 'location': latLng }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            success(results);
        } else {
            error(status);
        }
    });
}

     html, body {
            height: 100%;
            margin: 0;
            padding: 0;
        }

        #map {
            height: 100%;
        }

要通过邮政编码添加标记，您需要使用邮政编码替换数组中的纬度/经度坐标，然后对其进行地理编码。

// updated array
var locations = [
    ['Manchester', 'M3 3JU', 'https://www.google.co.uk'],
    ['Chester', 'CH1 2DY', 'https://www.google.co.uk'],
    ['Liverpool', 'L3 8EN', 'https://www.google.co.uk/']
];
// geocoding function
function codeAddress(location) {
    geocoder.geocode({
        'address': location[1]
    }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
            var marker = new google.maps.Marker({
                map: map,
                title: location[1],
                url: locations[2],
                position: results[0].geometry.location
            });
            bounds.extend(marker.getPosition());
            map.fitBounds(bounds);

            google.maps.event.addListener(marker, 'dblclick', function () {
                window.location.href = this.url;
            });

            google.maps.event.addListener(marker, 'click', (function (marker, location) {
                return function () {
                    infowindow.setContent(location[0]);
                    infowindow.open(map, marker);
                };
            })(marker, location));
        } else {
            alert("Geocode was not successful for the following reason: " + status);
        }
    });
}
