Question

我正在尝试在Gmaps中创建地理围栏，然后将多个标记加载到地图上，但在此过程中，我使用checkGeofence()检查标记是否在地理围栏的边界内。如果是，那么我将它添加到地图中，如果不是，我想忽略它，只显示标记不在边界内的消息。

问题是当我尝试使用以下代码执行此操作时：

var poi_coordinates = [[32.27, 77.19],[32.25, 77.22] , [32.23, 77.21], [32.24, 77.17],[26.61,77.19]]

var lattitude = 32.25; //28.6339;
var longitude = 77.19; //77.2200;

//creating map
var map = new GMaps({
    div: '#map',
    lat: 32.25,
    lng: 77.19,
    zoom:10
});

//creating geofence
circle = map.drawCircle({
    lat: lattitude,
    lng: longitude,
    strokeColor: '#fff',
    strokeOpacity: 1,
    strokeWeight: 3,
    fillColor: 'rgba(75,255,0,0.2)',
    fillOpacity: 0.4,
    radius: 4000,
    editable: true,
});

//Plotting Main Coordinates
map.addMarker({
    lat: lattitude,
    lng: longitude,
    draggable: true,
    fences: [circle],
    outside: function (marker, fence) {
        alert('This marker has been moved outside of its fence');
    }
});

//Plotting extra coordinates
for (var a = 0; a < poi_coordinates.length; a++) {
    if (map.checkGeofence(poi_coordinates[a][0], poi_coordinates[a][1], circle)) {

        //Code work properly as it should if I add this alert line
        //alert(map.checkGeofence(poi_coordinates[a][0], poi_coordinates[a][1], circle))

        map.addMarker({
            lat: poi_coordinates[a][0],
            lng: poi_coordinates[a][1],
            draggable: true,
            fences: [circle],
            outside: function (marker, fence) {
                alert('This marker has been moved outside of its fence');
            }
        });
    }
    else {
        alert(poi_coordinates[a][0] + "," + poi_coordinates[a][1] + ' is out of the 4 Km fence')
    }
}

只有在我在地图上添加标记时添加了alert命令才有效。如果我不在那里添加alert命令，我不知道究竟发生了什么，但所有标记都会添加到地图中。

请帮忙。以下是jsfiddle上的代码：http://jsfiddle.net/e52792j5/16/

Gmaps checkGeofence函数为所有坐标返回true
