Question

我有很多标记的Google地图。这是我的代码：

<div class="col-xs-12 col-sm-6 col-md-6 col-lg-6 padding_all_2">
<a href ="#" class="obj-1" id="obj-1"><div class="apartament_atrakcje">Atrakcja 1 pl</div></a>
</div>
<div class="col-xs-12 col-sm-6 col-md-6 col-lg-6 padding_all_2">
<a href ="#" class="obj-2" id="obj-2"><div class="apartament_atrakcje">Atrakcja 2 PL</div></a>
</div>




<div id="map_canvas"></div>

<script>
  window.onload = function () {
      var styles = [{"featureType":"all"}];
      var bounds = new google.maps.LatLngBounds();
      var options = {
          mapTypeControlOptions: {
              mapTypeIds: ['Styled']
          },
          center: new google.maps.LatLng(11, 22),
          zoom: 15,
          disableDefaultUI: true,
          mapTypeId: 'Styled'
      };
      marker = new google.maps.Marker({
          map:map,
      });
      var div = document.getElementById('map_canvas');
      var map = new google.maps.Map(div, options);
      var styledMapType = new google.maps.StyledMapType(styles, { name: 'Styled' });


      var markers = [
   ['Atrakcja 1 pl', 51.73925413, 19.51309225, 'Atrakcja 1 pl', '#', 'poi.png'],
   ['Atrakcja 2 PL', 53.41475000, 14.60220358, 'Atrakcja 2 PL', '#', 'poi.png'],
   ['Biskupia', 51.93780943, 15.52505514, 'Biskupia', '#', 'poi2.png']
      ];
      var infoWindow= new google.maps.InfoWindow({maxWidth:600}),
          marker, i,
          image = 'http://localhost/apartamenty/assets/poi.png';

      for( i = 0; i < markers.length; i++ ) {
          var beach = markers[i];
          var position = new google.maps.LatLng(beach[1], beach[2]);
          bounds.extend(position);
          marker = new google.maps.Marker({
              position: position,
              map: map,
              icon: 'http://localhost/apartamenty/assets/' + beach[5],
              title: beach[0],
              myurl: beach[4]
          });

          google.maps.event.addListener(marker, 'click', (function(marker, i) {
              return function() {
 infoWindow.setContent('<a href="'+marker['myurl']+'">'+marker['title']+'</a>');
 infoWindow.open(map, marker);
              }
          })(marker, i));
          map.fitBounds(bounds);
          map.mapTypes.set('Styled', styledMapType);

      }
  }
               </script>

我有一张地图及其上的标记。没关系！

在单击链接obj-1或obj-2之后，我要：

- center the map on this one, selected marker 
- display the marker of this marker

如果用户单击链接“ Atrakcja 1 pl”，则地图将以标题为Atrakcja 1 pll的标记居中，并且其提示将可见。

有人知道如何在我的代码中做到这一点吗？

一种选择是将对标记的引用保留在数组中，并将DOM单击侦听器添加到“链接”以打开标记的信息窗口，并将地图置于该标记的中心。

创建一个标记数组：

var gmarkers=[];

for (i = 0; i < markers.length; i++) {
  var beach = markers[i];
  var position = new google.maps.LatLng(beach[1], beach[2]);
  bounds.extend(position);
  marker = new google.maps.Marker({
    position: position,
    map: map,
    // icon: 'http://localhost/apartamenty/assets/' + beach[5],
    title: beach[0],
    myurl: beach[4]
  });
  gmarkers.push(marker);
  // ...

将点击侦听器添加到您的“链接”，以打开该标记的InfoWindow并将地图居中放置其位置：

  if (document.getElementById('obj-'+(i+1))) {
     // relies on the naming convention in your posted code
     google.maps.event.addDomListener(document.getElementById('obj-'+(i+1)), 'click', function(i) {
     return function() {
        google.maps.event.trigger(gmarkers[i], 'click');
        map.setCenter(gmarkers[i].getPosition());
     }}(i))
  }
