Ada cara yang lebih mudah selain menggunakan fungsi close (). jika Anda membuat variabel dengan properti InfoWindow, ia menutup secara otomatis saat Anda membuka yang lain.
var info_window;
var map;
var chicago = new google.maps.LatLng(33.84659, -84.35686);
function initialize() {
var mapOptions = {
center: chicago,
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
info_window = new google.maps.InfoWindow({
content: 'loading'
)};
createLocationOnMap('Location Name 1', new google.maps.LatLng(33.84659, -84.35686), '<p><strong>Location Name 1</strong><br/>Address 1</p>');
createLocationOnMap('Location Name 2', new google.maps.LatLng(33.84625, -84.36212), '<p><strong>Location Name 1</strong><br/>Address 2</p>');
}
function createLocationOnMap(titulo, posicao, conteudo) {
var m = new google.maps.Marker({
map: map,
animation: google.maps.Animation.DROP,
title: titulo,
position: posicao,
html: conteudo
});
google.maps.event.addListener(m, 'click', function () {
info_window.setContent(this.html);
info_window.open(map, this);
});
}
