Check if infowindow is opened Google Maps v3

Question

Please, I need a help.

I want to check if my infowindow is opened.

For example:

if (infowindow.isOpened)
{
   doSomething()
}

or

if (infowindow.close)
{
   doAnotherthing();
}

I dont have any idea, how to do this

This is an undocumented feature, and is therefore subject to change without notice, however the infoWindow.close() method sets the map on the object to null (this is why infoWindow.open(map, [anchor]) requires that you pass in a Map), so you can check this property to tell if it is currently being displayed:

function isInfoWindowOpen(infoWindow){
    var map = infoWindow.getMap();
    return (map !== null && typeof map !== "undefined");
}

if (isInfoWindowOpen(infoWindow)){
    // do something if it is open
} else {
    // do something if it is closed
}

Update: Another potentially useful way to write this is to add an isOpen() method to the InfoWindow prototype.

google.maps.InfoWindow.prototype.isOpen = function(){
    var map = this.getMap();
    return (map !== null && typeof map !== "undefined");
}
