javascript - Center Google Maps (V3) on browser resize (responsive)

Question

I have a Google Maps (V3) in my page at 100% page width with one marker in the middle. When I resize my browser window's width I would like the map to stay centered (responsive). Now the map just stays at the left side of the page and gets smaller.

UPDATE Got it to work exactly as described thanks to duncan. This is the final code:

var center;
function calculateCenter() {
  center = map.getCenter();
}
google.maps.event.addDomListener(map, 'idle', function() {
  calculateCenter();
});
google.maps.event.addDomListener(window, 'resize', function() {
  map.setCenter(center);
});

You need to have an event listener for when the window resizes. This worked for me (put it in your initialize function):

google.maps.event.addDomListener(window, 'resize', function() {
    map.setCenter(center);
});
