Have just one InfoWindow open in Google Maps API v3

Question

I need to have only one InfoWindow open on my Google Map. I need to close all other InfoWindows before I open a new one.

Can someone show me how to do this?

Solved it this way:

function window(content){
    google.maps.event.addListener(marker,'click', (function(){
        infowindow.close();
        infowindow = new google.maps.InfoWindow({
            content: content
        });
        infowindow.open(map, this);
    }))
}
window(contentHtml);
