title: How to make Google marker url open in a new browser window or tab?
body: <p>I have some markers on a Google map and would like to make it open a new tab or window when they are clicked on. I only am able to open the clicked marker url in the same browser window tab.</p>
  
  <p>This is how it works now...</p>
  
  <pre><code>var latlon = new google.maps.LatLng(MAP_FOCUS_LATITUDE, MAP_FOCUS_LONGITUDE);
  var myOptions = {
     center : latlon,
     zoom : 14,
     mapTypeId : google.maps.MapTypeId.ROADMAP,
     mapTypeControl : false,
     navigationControlOptions : {
     style : google.maps.NavigationControlStyle.LARGE
     }
  };
  var map = new google.maps.Map(document.getElementById("mapholder"), myOptions);
  var marker = new google.maps.Marker(
  {
      position : new google.maps.LatLng(10.0,20.0),
      title : "Blah",
      url : "http://www.myurltest.com"
  });
  
  google.maps.event.addListener(marker, 'click', function() { 
      window.location.href = this.url;
  });
  </code></pre>
  
  <p>In HTML, normally you can do this to open a link in a new tab... so how do I get this effect ?              </p>
  
  <pre><code>&lt;a href="http://www.myurltest.com" target="_blank"&gt;Blah blah&lt;/a&gt;
  </code></pre>
  
  <p>I would appreciate any assistance !</p>
