title: Remove Marker in Google API V3
body: <p>I would like to remove a marker in Google Maps, but I don´t understand this. Please help me.</p>
  
  <p>My Validation.js: </p>
  
  <pre><code>function initialize() {
  //geocodierungs Funktion damit Geocoding funktioniert
  geocoder = new google.maps.Geocoder();  
  var mapOptions = {
      zoom:5,
      center: new google.maps.LatLng(48.136607,11.577085),
      mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
  
  var pos=new google.maps.LatLng(48.2,11);
  var marker = new  google.maps.Marker({
      position:pos,
      map:map,
      title: 'test'
  });}    setInterval(function(){         
         //$.post('nav_schnittstelle.php',{}).done(aktualisiereKartendaten);
         alert('test');
         pos.setMap(null); },10000);
