对不起,如果这已被回答在别的地方,但当我添加一个侦听器到我的地图,它会导致我的标记隐藏/不加载,所以有人可以解释如何加载infowindow和中心到标记点击?Google地图中心和InfoWindow

继承人到目前为止我的代码:

编辑:

我现在已经改变了我的代码,包括阵列,它工作得很好,但现在我要标记到地图时,在中央点击,我想所有的标记都在窗口中,但fitBounds似乎没有做任何事情。它可以在这里http://www.everythingcreative.co.uk/marker

要重复使用相同的变量'marker'因此对于所有标记他们不存储和手柄丢失。你可以创建一个数组并将所有创建的标记存储在该数组中,然后调用它们并使用markerName.visible('true') –

嗨,我该怎么做?或者你能指导我到哪里我可以学习阵列? –

其实我现在明白了,但是如何在数组中定义图标和infowindow呢? –

表示要集中在一个标记在地图上被点击时,改变你的代码,这样做:

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)); 

为fitBounds工作,你必须通过。扩展方法一个google.maps.LatLng对象。要做到这一点给你的现有代码的最简单的方法是把它放在你的“标识控制”循环:

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);
