Hello.
I wrote the following code to display markers. There are 2 buttons which show Next or Previous Infowindow for markers. But problem is that InfoWindows are not shown using google.maps.event.trigger
Can someone help me with this problem. Thank you.
Here is code:

var infowindow;
var map;
var bounds;
var markers = [];
var markerIndex=0;
function initialize() {
var myLatlng = new google.maps.LatLng(41.051407, 28.991134);
var myOptions = {
zoom: 5,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
markers = document.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var latlng = new google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var marker = createMarker(markers[i].getAttribute("name"), latlng, markers[i].getAttribute("phone"), markers[i].getAttribute("distance"));
}
rebound(map);
}
function createMarker(name, latlng, phone, distance) {
var marker = new google.maps.Marker({position: latlng, map: map});
var myHtml = "<table style='width:100%;'><tr><td><b>" + name + "</b></td></tr><tr><td>" + phone + "</td></tr><tr><td align='right'>" + distance + "</td></tr></table>";
google.maps.event.addListener(marker, "click", function() {
if (infowindow) infowindow.close();
infowindow = new google.maps.InfoWindow({content: myHtml});
infowindow.open(map, marker);
});
return marker;
}
function rebound(mymap){
bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(new google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),parseFloat(markers[i].getAttribute("lng"))));
}
mymap.fitBounds(bounds);
}
function showNextInfo()
{
if(markerIndex<markers.length-1)
markerIndex++;
else
markerIndex = 0 ;
alert(markers[markerIndex].getAttribute('name'));
google.maps.event.trigger(markers[markerIndex],"click");
}
function showPrevInfo()
{
