title: js geolocation but without prompting - possible?
body: <p>Is it possible to get the geolocation of a user without the browser prompt?</p>
  
  <p><a href="http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_geolocation" rel="nofollow noreferrer">Here's the code sample from W3</a></p>
  
  <pre><code>&lt;script&gt;
     var x = document.getElementById("demo")
  
     function getLocation(){
       if(navigator.geolocation){
         navigator.geolocation.getCurrentPosition(showPosition);
       } else {
         x.innerHTML="Geolocation is not supported by this browser.";}
       }
       function showPosition(position){
         x.innerHTML="Latitude: " + position.coords.latitude + 
         "&lt;br&gt;Longitude: " + position.coords.longitude;   
       }
  &lt;/script&gt;
  </code></pre>
  
  <p>Is there any <code>preventPrompt()</code>-like function ? </p>
