Remove Marker in Google API V3
<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);
</code></pre>

<p>How can I use <code>setMap(Null);</code>? I don´t understand this. </p>
