如何在我的浏览器上获取当前位置

hey guys i'm trying to find my current location on my browser , this is my html index file :

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Geocoding Page</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
  <script>
  function getLocation() {
      if (navigator.geolocation) {
          navigator.geolocation.getCurrentPosition(savePosition, positionError, {timeout:10000});
      } else {
          //Geolocation is not supported by this browser
      }
  }

  // handle the error here
  function positionError(error) {
      var errorCode = error.code;
      var message = error.message;

      alert(message);
  }

  function savePosition(position) {
            $.post("geocoordinates.php", {lat: position.coords.latitude, lng: position.coords.longitude});
  }
  </script>
</head>
<body>
    <button onclick="getLocation();">Get My Location</button>
</body>
</html>

and that's the geocoordinates.php file :

<?php

if(isset($_POST['lat'], $_POST['lng'])) {
    $lat = $_POST['lat'];
    $lng = $_POST['lng'];

    $url = sprintf("https://maps.googleapis.com/maps/api/geocode/json?latlng=%s,%s", $lat, $lng);

    $content = file_get_contents($url); // get json content

    $metadata = json_decode($content, true); //json decoder

    if(count($metadata['results']) > 0) {
        // for format example look at url
        // https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452
        $result = $metadata['results'][0];

        // save it in db for further use
        echo $result['formatted_address'];

    }
    else {
        // no results returned
    }
}

?>

i found this as an answer for a previous question but when i run it on browser it gives me an error as : user denied goelocation so can any one help ?????

          break;
        case error.POSITION_UNAVAILABLE:
          x.innerHTML="Location information is unavailable."
          break;
        case error.TIMEOUT:
          x.innerHTML="The request to get user location timed out."
          break;
        case error.UNKNOWN_ERROR:

      }
    </script>
    

    Please see here for more details:-http://www.w3schools.com/html/html5_geolocation.asp Here the javascript gives the latitude and longitude and checks the exact location of you.
