Question

我之前从地址字符串中获取了页面加载时的所有标记坐标，我现在知道它非常糟糕。我重构了代码，它工作得很好但是clustermarkerer无法加载。

所有我进入萤火虫的是：

TypeError: marker.getPosition is not a function


return bounds.contains(marker.getPosition());

我一直在尝试很多事情，所以可能会有一两个不必要的线。

简单地说，标记数组并未完全填充。我添加了tempMarkers来推送具有所需属性的标记。

                    var tempMarkers = [];
                for (i = 0; i < locations.length; i++) {

                    marker = new google.maps.Marker({
                        position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                        map: map,
                        animation: google.maps.Animation.DROP,
                        icon: "../images/musicMarker.png"

                    });
                    tempMarkers.push(marker);

                }

然后将数组添加到clusterer：

markerClusterer = new MarkerClusterer(map, tempMarkers, mcOptions);

希望它可以帮助有同样错误的人！
