How to close all popups?

I have multiple (444) popups open on my map.
I tried this:
$(".leaflet-popup-close-button").each(function (index) {
$(".leaflet-popup-close-button")[index].click();
});
But this way, not all get closed. Only half of them get removed. Exactly half. So first time 222 get removed, the second time 111 get removed.
Why is this happening?

For recent versions of Leaflet:
The proper way to close a popup is to use the built-in .closePopup() method:
map.closePopup();
If you have multiple layers with different popups (like in the OP's case), then you could iterate over the layers and close the popup on each layer:
map.eachLayer(function (layer) {
layer.closePopup();
});

This is what i did to solve my problem:
var firstLayer = true;
map.eachLayer(function (layer) {
// do something with the layer
if (firstLayer) {
firstLayer = false;
} else {
map.removeLayer(layer);
}
//console.log(layer);
});
I have 3 layers, the first one is the main one which displays my map, that's why it mustn't be removed. I removed the second and the third one which are both layers with multiple popups on it.
Thanks #rafaelbiten who pointed me in the right direction (layers).

I see what you're trying to do, but that doesn't seem to be a very good idea. You're literally (programmatically) causing 444 clicks that don't really exist to happen. If one day you decide to track user clicks on those items, you'll have a problem.
What if you try to add a class to the common parent of those 444 leaflet-popup-close-button that force them, via CSS to collapse/close?
Something like that would be a better solution for what you're trying to do.
Btw, checking their docs it seems like these popups are all open on a new layer, so you probably just need to remove that layer and all of them will be gone.
From their docs:
Use Map#openPopup to open popups while making sure that only one popup is open at one time (recommended for usability), or use Map#addLayer to open as many as you want.
And checking further you have addLayer and removeLayer. Whatever you do, I'd suggest you avoid all those programmatically clicks.

Select GeoJSON features with a mouse interaction - OpenLayers 3

I have GeoJSON features that consists of many little features. When I hover over one of them, I want the whole layer to be selected and not only a part of my layer.
I don't know where to start to achieve that... anyone can help me ?
This is my code for the moment:
var hoverClick = new ol.interaction.Select({
condition: ol.events.condition.pointerMove,
});
select = hoverClick;
olMap.addInteraction(select);
Thanks

Instead of using an ol.interaction.Select, you could listen to the map pointermove event and use the ol.Map#forEachFeatureAtPixel method. If there's a feature (from your layer) at the location of the pointer, then apply the wanted style to the layer.

Restrict overlays in mapbox

So I am creating a map using Leaflet and Mapbox with multiple overlays and base maps. Currently I have a layers control where these are separated and you can only show one base map at a time, but all the overlays can be shown at once.
However, I have two overlays which interfere with each other and I would like to make it so that if one is checked in the control, the other is unchecked and vice versa. Is there any way to do this?
I am anticipating something like this, but am open to any suggestions.
var layer1 = L.mapbox.tileLayer('mapid1');
var layer2 = L.mapbox.tileLayer('mapid2');
var layerControl = L.control.layers(baseMaps, {"L1": layer1, "L2": layer2}).addTo(map);
map.on("overlayadd", function(e) {
if (e.name === "L1"){
L.layers.control.uncheck(layer2);
} else if (e.name === "L2") {
L.layers.control.uncheck(layer1);
};
});
Thank you!!

Working fiddle.
I don't know if there's an easier way. It seems the library doesn't offer many options to manipulate the L.control.layers overlays.
What I'm doing is firing a click on the conflicting overlay. To achieve this, a little DOM manipulating is needed. You can store an id reference when creating overlay's label.

Leaflet - toggling GeoJSON layers without plug-ins

I know how to add a layer with markers, which I can toggle on/off and how to add GeoJSON layer to my map.
But I can't mix these functions.
I need to create a toggling layer from GeoJSON (polyline layer).
Is it possible to get what I need without any external plug-ins or scripts?

GeoJSON Layers and Markers can be used together without problem.
To be able to toggle your layers, you need to catch some sort of click event from something you can click on, for example a button.
From my research what I found is if you need a custom button, it is not so quick to implement yourself, so you might need to use one of the available plugins.
If you still do not want to build a button or use a plugin, you could for example set a click event on the map itself, which toggles the GeoJSON layer on and off.
I took the GeoJSON example from the leaflet website and changed it so it toggles the GeoJSON layer on and off:
var geoLayer = L.geoJson([
// ...
]);
map.on('click', function() {
if(map.hasLayer(geoLayer)) {
map.removeLayer(geoLayer);
} else {
map.addLayer(geoLayer);
}
});
Hope that helps..
Edit:
I changed the example to use the layer control of leaflet.js
which is much better...
var baseLayers = {
"Markers": markerLayer,
"GeoJSON": geoLayer
};
L.control.layers(baseLayers).addTo(map);
Didn't know about this ;)
If you want checkboxes instead of radiobuttons, use this instead
L.control.layers(null, baseLayers).addTo(map);

Google Maps JavaScript API: How to remove individual marker?

I'm using the Google Maps v3 library, with the Multi-Marker library which extends the functionality of Google Maps for super fast adding of map marker icons to a map.
I can't figure out how to remove a single, individual map marker using the multi-marker library linked above.
Does anyone have any ideas how I'd do this using the multi-marker library (and/or Google Maps)? I've tried contacting the lead developer of the project but am not getting a response.
Thanks for any help.
Also, linked is more information on this library
http://blog.redfin.com/devblog/2010/07/introducing_multimarker_the_fastest_way_to_add_many_hundreds_or_thousands_of_markers_on_google_maps.html
UPDATE:
I have linked example code of what I'm doing. I want to dynamically remove specific map marker icons (overlays) but am struggling on how to do that. Any advise would be very appreciated. Thanks
Live example:
http://multimarker.googlecode.com/svn/trunk/fast-marker-overlay/maps-v3/example/clickable.html

Normaly, using only the google maps api, to remove an overlay from the map you would need to call the setMap(null) method on the overlay.
As I can see, the Multi-Marker library uses an array to hold all the markers and creates an overlay to show on the map, an overlay that contains the markers. To remove one, it should work to remove the marker from the array (you need to know its position in the array) and redraw the overlay.
Edit:
You need something similar to function clearOverlays() { var i = overlays.length; while (i--) { var overlay = overlays[i]; if (overlay) overlay.setMap(null); delete overlays[i]; } }
But you'll need to know the position in the array of the marker you want to delete. The function will look like this:
function clearOneOverlay(var position) { var overlay = overlays[position]; if (overlay) overlay.setMap(null); delete overlays[position]; }

try this: remember which marker you click and then remove it later
consider following code(Google Maps v2)
var current_marker;
GEvent.addListener(marker, "click", function() {
current_marker = marker;
});
//remove later
current_marker.setMap(null);
