title: Google Maps API v3: Opening the link on a marker in a new window
body: <p>seems like a pretty basic thing, but I don't seem to be finding the answer.
  Here's my Google Maps code:</p>
  
  <pre><code>var marker = new google.maps.Marker({
        position: new google.maps.LatLng(123, 123),
        url: "http://www.google.com",
        map: map
      });
  </code></pre>
  
  <p>...</p>
  
  <pre><code>google.maps.event.addListener(marker, 'click', function() {
      window.location.href = marker.url;
  });
  </code></pre>
  
  <p>What do I need to change, to open the link in a new window?</p>
  
  <p>Many thanks!</p>
