谷歌地图API 3-信息窗口问题

创建一个全局变量（或在setMarkers函数内），infowindow:

 var infowindow =  new google.maps.InfoWindow({
            content: ""
        });

然后在循环中，调用一个新函数，传递您需要的各种参数：

for (var i = 0; i < locations.length; i++) {
    var location = locations[i];
    var myLatLng = new google.maps.LatLng(location[1], location[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        icon: image,
        shape: shape,
        title: location[0],
        zIndex: location[3]
    });
    bindInfoWindow(marker, map, infowindow, location[0]);
  }

然后创建一个新的全局函数，将点击事件绑定到标记，并打开具有指定内容的信息窗口：

 function bindInfoWindow(marker, map, infowindow, strDescription) {
        google.maps.event.addListener(marker, 'click', function() {
            infowindow.setContent(strDescription);
            infowindow.open(map, marker);
        });
    }

更新：这是我使用的完整代码

您需要将click事件绑定到标记，即在创建标记后，您需要将它们存储在数组中。然后添加以下代码

var marker = new google.maps.Marker({       
    position: position  
});

var infowindow = new google.maps.InfoWindow({
  content:"Any content or latitude longitude info"
});
google.maps.event.addListener(marker, 'click', function() {
  infowindow.open(map,marker);
});

这里有点棘手，即如果有多个标记，则需要相应地构建marker变量。在您的情况下，您可以将for循环计数器"i"附加到标记变量（如markr_+i），然后在同一循环内的这些变量上触发click事件。
