请您查看This Demo并告诉我是否可以通过选中和取消选中复选框来禁用或启用地图上的Markercluster？
目前我所拥有的是一个使用MarkerCluster插件启用的简单地图，我正在寻找一种方法来启用或禁用此设施，而无需重新绘制地图？
$(document).ready(function () {
var latlng = new google.maps.LatLng(49.247477, -123.128000);
var myOptions = {
zoom: 11,
center: latlng,
disableDefaultUI: true,
scaleControl: true,
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.SMALL
},
mapTypeControl: true,
draggableCursor: 'move',
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
locations.length = 0;
var markers = [];
for (p = 0; p < data.markers.length; p++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.markers[p].LATITUDE, data.markers[p].LONGITUDE),
map: map,
title: "marker " + p
});
markers.push(marker);
}
var markerCluster = new MarkerClusterer(map, markers);
});

google.maps.event.addDomListener(document.getElementById('cluster'),'click', function() {
var set;
if (document.getElementById('cluster').checked) {
set = map;
} else {
set = null;
}
markerCluster.setMap(set);
});
工作代码段：
var map;
var locations = [];
$(document).ready(function() {
var latlng = new google.maps.LatLng(49.247477, -123.128000);
var myOptions = {

zoomControl: true,
zoomControlOptions: {

},
mapTypeControl: true,
draggableCursor: 'move',
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
locations.length = 0;
var markers = [];
for (p = 0; p < data.markers.length; p++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.markers[p].LATITUDE, data.markers[p].LONGITUDE),
map: map,

});
markers.push(marker);
}
var markerCluster = new MarkerClusterer(map, markers);
google.maps.event.addDomListener(document.getElementById('cluster'), 'click', function() {
