title: Google Maps API InfoWindow should be open by default
body: <p>I am try the Google Maps API and run into a little problem. Look at this example below. I want to have a Infobox open when I go to the site (not like in this example from google that it is cloesed and triggered by an click event). How to manage this? Maybe this is a beginners question to a Google Maps Api pro^^ </p>
  
  <pre><code>&gt;  function initialize() {
  &gt;     var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
  &gt;     var myOptions = {
  &gt;       zoom: 4,
  &gt;       center: myLatlng,
  &gt;       mapTypeId: google.maps.MapTypeId.ROADMAP
  &gt;     }
  &gt;  
  &gt;     var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  &gt;  
  &gt;     var contentString = '&lt;div id="content"&gt;'+
  &gt;         '&lt;div id="siteNotice"&gt;'+
            'hello world&lt;/div&gt;'+
  &gt;         '&lt;/div&gt;';
  &gt;         
  &gt;     var infowindow = new google.maps.InfoWindow({
  &gt;         content: contentString
  &gt;     });
  &gt;  
  &gt;     var marker = new google.maps.Marker({
  &gt;         position: myLatlng,
  &gt;         map: map,
  &gt;         title: 'Uluru (Ayers Rock)'
  &gt;     });
  &gt;     google.maps.event.addListener(marker, 'click', function() {
  &gt;       infowindow.open(map,marker);
  &gt;     });   }
  </code></pre>
