here I needed to do the same thing
assume a master js object myMap that is a global refernce to all map
goodies eg
var myMap = {
Icons: null,
map: null, //new google.maps.Map
bounds: null, //new google.maps.LatLngBounds()
geocoder: null, //new google.maps.Geocoder();
trafficInfo: null, //new google.maps.TrafficLayer();
markerCluster:null, //new MarkerClusterer
markerOverlays : [], //array of marker we add to map
}
function clearOverlays(aOverlays) {
if (aOverlays) {
for (i in aOverlays) {
aOverlays[i].setMap(null);
if (aOverlays[i].infowindow)
aOverlays[i].infowindow.close();
}
}
}
function getOverlays(id) {
var bFound = false;
if (aOverlays) {
for (i in aOverlays) {
if (id == aOverlays[i].id) {
bFound = true;
break;
} (id == aOverlays[i].id)
} //for (i in aOverlays)
if (getOverlays.arguments.length == 2) {
if (bFound)
return aOverlays[i];
else
return null;
}
else {
if (bFound)
return true;
else
return false;
} //(getOverlays.arguments.length == 2
} //if (aOverlays)
} //getOverlays(id)
function setInfowindow(marker,sInfo) {
var infowindow = new google.maps.InfoWindow({
content: sInfo
});
//you can add as many listener to a marker as you want
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(ecMap.map,marker);
//$("#tabs").tabs(); //can use with special css jquery ui
});
google.maps.event.addListener(marker, 'click', function() {
// alert(marker.id);
});
return infowindow
} //setInfowindow(marker,sInfo)
function getMarker(map,latlng,id,sIcon,sTitle,sLabel, sInfo) {
var shape = {
coord: [1, 1, 1, 20, 18, 20, 18 , 1],
type: 'poly'
};
var lMarker = new google.maps.Marker({
id: id , //all gObject/arrays allow ad hoc string or object
assigments
infowindow : null;
position: latlng,
visible:true,
shape: shape,
icon: sIcon, //"A", if sIcon is blank the markes wont show on
the map except the 1st Icon
label: sLabel ,
title: sTitle //show as tool tip
});
lmarker.infowindow = setInfowindow(lmarker, sInfo);
return lMarker;
}
var marker = getMarker(myMap.map,latlng,id,sIcon,title,label. sInfo)
myMap.bounds.extend(latlng); // extend the bounds to include the new
point how to marker.getLatLng()
myMap.map.fitBounds(myMap.bounds); //causes a stack over in ie7-8 if
latlng.lat=NaN, latlng=NaN
myMap.markerOverlays.push(marker);
then you can so stuff like
if you know the id you assigned to the marker
marker = getOverlays("12345',true)
if (marker.infowindow)
marker .infowindow.close();
or if you want to close all infowindows
clearOverlays(myMap.markerOverlays)
