[OpenLayers-Users] Removing popups with clicks on map

[Robert Buzink]

hi Alex,

You can find a way to pick up a clickevent in the map at
http://openlayers.org/dev/examples/click.htm :

map.events.register("click", map, function(e) {
                var lonlat = map.getLonLatFromViewPortPx(e.xy);
                alert("You clicked near " + lonlat.lat + " N, " +
                                          + lonlat.lon + " E");
            });


You can change the alert part to a destroy popup code. You should know
though that the code you've written destroys a specific popup, named
'popup'. The add function in this example could also have been:

daspop = new OpenLayers.Popup("chicken",
                                         new OpenLayers.LonLat(5,40),
                                         new OpenLayers.Size(200,200),
                                         "example popup",
                                         true);

            map.addPopup(daspop);


In which case the destroy code would have been:

markers.map.removePopup(daspop);
                daspop.destroy();
                daspop = null;


In other words, in your code you will have to find out the name of the popup
that is being shown, before you can destroy it. I have no idea how you
should do that. Maybe someone else could answer that (or correct me when I'm
wrong)?
