谷歌地图中心和InfoWindow

Question

对不起，如果这已经在其他地方得到了解答，但是当我向地图添加一个监听器时，它会导致我的标记隐藏/不加载，所以有人可以解释如何在点击时加载infowindow和居中到标记吗？

到目前为止我的代码：

<section id="wrapper">
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<article>
</article>
<script>
function success(position) {
  var mapcanvas = document.createElement('div');
  mapcanvas.id = 'mapcontainer';
  mapcanvas.style.height = '600px';
  mapcanvas.style.width = '100%';
  document.querySelector('article').appendChild(mapcanvas);

  var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
  var options = {
    zoom: 12,
    //center: coords,
    center: new google.maps.LatLng(51.416741,-0.543854),
    mapTypeControl: false,
    navigationControlOptions: {
        style: google.maps.NavigationControlStyle.SMALL
    },
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("mapcontainer"), options);

  // Geolocation
  var marker = new google.maps.Marker({
      position: coords,
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/micons/blue-dot.png',
      title:"You are here!",
  });

  // Great Fosters
  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(51.416741,-0.543854),
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/icons/yellow-dot.png',
      title:"Great Fosters",
  });

  // St Matthews
  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(51.432327,-0.459162),
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/icons/orange-dot.png',
      title:"St Matthews",
  });

  // ----- STAINES HOTELS - START -----
  var marker = new google.maps.Marker({

      title:"Travel Lodge Staines",
  });

  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(51.432156,-0.51617),
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/icons/green-dot.png',
      title:"Thames Lodge Staines",
  });

  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(51.43218,-0.516293),
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/icons/green-dot.png',
      title:"The Boleyn Staines",
  });

  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(51.432534,-0.516422),
      map: map,
      icon:'http://maps.google.com/mapfiles/ms/icons/green-dot.png',
      title:"The Swan Staines",
  });
  // ----- STAINES HOTELS - END -----

}
if (navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(success);
} else {
  error('Geo Location is not supported');
}

编辑：

我现在已经改变了我的代码以包含数组并且它运行得很好但是现在我希望标记在点击时居中在地图上并且我希望所有标记都在窗口中但是fitBounds似乎没有做任何事情。它可以在这里显示http://www.everythingcreative.co.uk/marker

要在点击标记时将地图置于标记中心，请更改代码以执行此操作：

google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
        // center on marker
        map.setCenter(marker.getPosition());
        // open the infowindow
        infowindow.setContent(markers[i][0]);
        infowindow.open(map, marker);
    }
})(marker, i));

要使fitBounds正常工作，您必须将.extend方法传递给google.maps.LatLng对象。鉴于现有代码，最简单的方法是将它放在“标记控制”循环中：

var bounds = new google.maps.LatLngBounds();
for (i = 0; i < markers.length; i++) {  
    marker = new google.maps.Marker({
        position: new google.maps.LatLng(markers[i][1], markers[i][2]),
        map: map,
        icon: markers[i][3]
    });
    bounds.extend(marker.getPosition());
    google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
            infowindow.setContent(markers[i][0]);
            infowindow.open(map, marker);
        }
    })(marker, i));
}
map.fitBounds(bounds);
