[OpenLayers-Users] Destroying all the features in a vector layer

[Simone Gadenz]

Thanks this helps a lot. In case, would be possible to retrieve the name of the popup, I mean the one specified in the following line:

popup = new OpenLayers.Popup("chicken",

so that something like this makes sense:

for (var i = map.popups.length - 1; i >= 0; --i) {
	if (map.popup[i].NAME == "chicken){    
		map.removePopup(map.popups[i]);
	}
}

Thnaks

There's nothing in the API. But you can do it with this:

for (var i = map.popups.length - 1; i >= 0; --i) {
    map.removePopup(map.popups[i]);
}
