close InfoWindow before open another

Question

I have a problem with InfoWindow. I have an ajax function that retrieves data via JSON, but I can not get close InfoWindow automatically when you open another. My code is th

Answer 1

function infoCallback(infowindow, marker) { 
  return function() {
     infowindow.close();  
    infowindow.open(map, marker);

  };
}

should be changed to

function infoCallback(infowindow, marker) { 
    return function() {
        //Close active window if exists
        if (activeWindow != null) {
            activeWindow.close();
        }
        //Open new window 
        infowindow.open(map,marker); 
        //Store new window in global variable 
        activeWindow = infowindow; 
    };
}

and declare activeWindow as a global variable in your .js file as var activeWindow.
