Hi, where I have to put the code? I've tried but unsuccess...
I would structure it like this:
var POPUP; // global scope
function deletePopup() {
if (! POPUP) return;
map.removePopup(POPUP);
POPUP.destroy();
POPUP = null;
}
// GetfeatureInfo...
eventListeners: {
getfeatureinfo: function(event) {
deletePopup();
POPUP = new OpenLayers.Popup.FramedCloud(...);
map.addPopup(POPUP);
}
}
There's probably no substantial benefit of a global POPUP variable
versus iterating over map.popups, but I find it more easily readable.
The separation of deletePopup() into its own function, allows us to
close the popup from other program code without repeating code.
