I have searched the web high and low and have not been able to find a tutorial or example of using jQuery to fade an InfoBox/InfoWindow in Google Maps not the content the actual
i tried something similar for a website. here is my code. (gm-api-v3)
var infowindow = new google.maps.InfoWindow({
content: contentString
});
function iwFadeIn() {
infowindow.open(map, marker);
var iw_container = $(".gm-style-iw").parent();
iw_container.stop().hide();
iw_container.fadeIn(1000);
}
