?
????????// Creating an object literal containing the properties
????????// you want to pass to the map

????????????zoom: 3,
????????????center: new google.maps.LatLng(37.09, -95.71),
????????????mapTypeId: google.maps.MapTypeId.ROADMAP
????????};
?
????????// Creating the map
????????var map = new google.maps.Map(document.getElementById('map'), options);
?
????????// Creating an array which will contain the coordinates
????????// for New York, San Francisco and Seattle
????????var places = [];
?
????????// Adding a LatLng object for each city
????????places.push(new google.maps.LatLng(40.756, -73.986));
????????places.push(new google.maps.LatLng(37.775, -122.419));
????????places.push(new google.maps.LatLng(47.620, -122.347));
?
????????// Creating a variable that will hold the InfoWindow object
????????var infowindow;
?
????????// Looping through the places array
????????for (var i = 0; i < places.length; i++) {
?
????????????// Adding the markers
????????????var marker = new google.maps.Marker({
????????????????position: places[i],
????????????????map: map,
????????????????title: 'Place number ' + i
????????????});
?
????????????// Wrapping the event listener inside an anonymous function
????????????// that we immediately invoke and passes the variable i to.
????????????(function(i, marker) {
?
????????????????// Creating the event listener. It now has access to the values of
????????????????// i and marker as they were during its creation
????????????????google.maps.event.addListener(marker, 'click', function() {
?
????????????????????if (!infowindow) {
????????????????????????infowindow = new google.maps.InfoWindow();
????????????????????}
?
????????????????????// Setting the content of the InfoWindow
????????????????????infowindow.setContent('Place number ' + i);
?
????????????????????// Tying the InfoWindow to the marker
????????????????????infowindow.open(map, marker);
?
????????????????});

????????????})(i, marker);
?
????????}
?
????};
