Google Maps InfoBubble windows neither closing nor recentering map - google-maps-api-3

Question

I have a successful working GM prototype using InfoBubble here.
I need the map to recenter when I open each new InfoBubble window.
The map recenters on closing each InfoBubble because I call [line 238 etc]:
google.maps.event.addListener(infoBubble, "closeclick", function ()
Secondly, why doesn't the Los Angeles (United States West Coast, LA) InfoBubble also close the most recent InfoBubble window open as all the others do, please?
Thanks so much in advance for any suggestions; I know it must be simple - but have spent hours and hours and searched S/O too!
javascript:
$(document).ready(function () { initialize(); });
var myLatlng = new google.maps.LatLng(51.30, 0.7);
function initialize() {
google.maps.Map.prototype.setCenterWithOffset = function(LatLng, offsetX, offsetY) {
var map = this;
var ov = new google.maps.OverlayView();
ov.onAdd = function() {
var proj = this.getProjection();
var aPoint = proj.fromLatLngToContainerPixel(LatLng);
aPoint.x = aPoint.x+offsetX;
aPoint.y = aPoint.y+offsetY;
map.setCenter(proj.fromContainerPixelToLatLng(aPoint));
};
ov.draw = function() {};
ov.setMap(this);
};
var centerMap = new google.maps.LatLng(51.30, 0.7);
var mapOptions = {
zoom: 2,
disableDefaultUI: true,
scrollwheel: false,

var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
map.setCenterWithOffset(myLatlng, 50, 225);
setMarkers(map, sites);
google.maps.event.addListener(infoBubble, "closeclick", function () {

google.maps.event.addListener(infoBubbleLA, "closeclick", function () {

});

Answer 1

You have 2 different InfoBubbles in you code infoBubbleLA and infoBubble. Opening one won't close the the other.
var infoBubble = new InfoBubble({
maxWidth: 400,
});
var infoBubbleLA = new InfoBubble({
maxWidth: 400,
});
This should do that:
google.maps.event.addListener(marker, "click", function () {
map.setCenterWithOffset(myLatlng, 50, 25);
if (this.html == losangelescontentString) {
infoBubbleLA.setContent(this.html);
infoBubbleLA.open(map,this);
infoBubble.close();
} else {
infoBubble.setContent(this.html);
infoBubble.open(map,this);
infoBubbleLA.close();
}
});
