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 am using the google utility library marker with label (http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.1.5/docs/examples.html)
It is easy to use jquery on the labels.
google.maps.event.addListener(marker, "mouseover", function (e) {
//console.log(this); this.label.labelDiv_.style.display = 'block';
$(this.label.labelDiv_).fadeIn();
});
google.maps.event.addListener(marker, "mouseout", function (e) {
//this.label.labelDiv_.style.display = 'none';
$(this.label.labelDiv_).fadeOut();
});
