How to show / hide MarkerCluster in google maps v3?

Question

I need to have different markers for different mapTypes, and I click them on MarkerClusterer .

I will hide the markers with:

cluster.set("map", null);
cluster.resetViewport();
cluster.redraw();

And "show" them with:

cluster.set("map", MAP);
cluster.resetViewport();
cluster.redraw();

The problem is that MarkerClusterer does not seem to be like set("map", null); he gives an error TypeError: Object #<a MarkerClusterer> has no method 'remove'. How can I show / hide them appropriately?

Answer 1

I fought in this decision, a little beckoning and a little hacking. I am still waiting for a clean answer, but this is the solution to my problem, so I also post this:

MarkerClusterer.prototype.remove = function () {}

[..]

cluster.set("map", HIDDEN_MAP); // remove the clusterer
cluster.resetViewport();
cluster.redraw();

Answer 2

cluster.clearMarkers();

Answer 3

Javascript API v3 :

clusterer.setMap(null);

, .

clusterer.setMap( this.map );

:

.html add:

<div id="map-canvas-hidden" style="display:none"></div>
<div id="map-canvas-shown" style="width:500px; height:500px"></div>

in.js add:

MarkerClusterer.prototype.remove = function() { };
var HIDDEN_MAP = new google.maps.Map(document.getElementById("map-canvas-hidden"), {});
var gmap = new google.maps.Map(document.getElementById("map-canvas-shown"), {});

:

    cluster.setMap(gmap);
    cluster.resetViewport();
    cluster.redraw();

:

    cluster.setMap(HIDDEN_MAP);
    cluster.resetViewport();
    cluster.redraw();

, / ( Maps API JS-Cluster-Renderer). .

MarkerClusterer.prototype.remove = function() {};

MarkerClusterer.prototype.hide = function() {
  this.setMap(null);
  this.resetViewport();
};

MarkerClusterer.prototype.show = function() {
  this.setMap(map); // replace map with your reference to the map object
  this.redraw();
};

// To hide the clusters:
cluster.hide();

// To show the clusters:
cluster.show();
