我有以下代码来尝试让 MarkerClusterer 库为我的谷歌地图工作,但由于某种原因,它并没有改变任何东西。我有一些 jinja2 用于循环,但一切正常。你能看到任何错误吗?

var LatLng = centerlocation.replace("(", "").replace(")", "").split(", ")
var Lat = parseFloat(LatLng[0]);
var Lng = parseFloat(LatLng[1]);
var zoomAmt = 10;
var USA = new google.maps.LatLng(Lat, Lng);
var mapOptions = {
zoom: zoomAmt,
center: USA,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
// Global var
var infowindow = new google.maps.InfoWindow();
//markers array
var markers = [];
//put all the markers on the map
{% for location in locations %}
//need to do the JSON encoding because JavaScript can't have Jinja2 variables
//I need the safe here because Jinja2 tries to escape the characters otherwise
var GPSlocation = {{location.GPSlocation|json_encode|safe}};
var LatLng = GPSlocation.replace("(", "").replace(")", "").split(", ")
var Lat = parseFloat(LatLng[0]);
var Lng = parseFloat(LatLng[1]);
var markerLatlng = new google.maps.LatLng(Lat, Lng);
var title = {{location.title|json_encode|safe}}
var iwContent = {{location.render_front()|json_encode|safe}}
var marker = new google.maps.Marker({
position: markerLatlng,
title: title,
map: map
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(iwContent);
infowindow.open(map, marker);
});
//putting the marker onto the markers array
markers.push(marker);
{% endfor %}
//creating the marker cluster
var markerCluster = new MarkerClusterer(map, markers);
}
</script>
就像我说的那样,在我调用 MarkerClusterer 后地图看起来很正常。
