OpenLayers. Popup

A popup is a small div that can opened and closed on the map.  Typically opened in response to clicking on a marker.  See OpenLayers.Marker.  Popup’s don’t require their own layer and are added the the map using the OpenLayers.Map.addPopup method.

Example

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

map.addPopup(popup);
