EN

var prev_infowindow =false; 
...
base.attachInfo = function(marker, i){
    var infowindow = new google.maps.InfoWindow({
        content: 'yourmarkerinfocontent'
    });

    google.maps.event.addListener(marker, 'click', function(){
        if( prev_infowindow ) {
           prev_infowindow.close();
        }

        prev_infowindow = infowindow;
        infowindow.open(base.map, marker);
    });
}

//assuming you have a map called 'map'
var infowindow = new google.maps.InfoWindow();

var latlng1 = new google.maps.LatLng(0,0);
var marker1 = new google.maps.Marker({position:latlng1, map:map});
google.maps.event.addListener(marker1, 'click',
    function(){
        infowindow.close();//hide the infowindow
        infowindow.setContent('Marker #1');//update the content for this marker
        infowindow.open(map, marker1);//"move" the info window to the clicked marker and open it
    }
);
var latlng2 = new google.maps.LatLng(10,10);
var marker2 = new google.maps.Marker({position:latlng2, map:map});
google.maps.event.addListener(marker2, 'click',
    function(){
        infowindow.close();//hide the infowindow
        infowindow.setContent('Marker #2');//update the content for this marker
        infowindow.open(map, marker2);//"move" the info window to the clicked marker and open it
    }
