如何将地图放在当前用户位置（地理位置

Question

我有这个代码，我想集中在用户位置上，因为现在它将它置于我有的坐标下（在丹麦哥本哈根上方），并且它是固定的。让我的代码中心对用户位置的地图，并显示出它周围的点

function initialize() { 

var locations = [ 
    ['kastelet', 55.6911, 12.5939], 
    ['norebro', 55.6883, 12.5597], 
    ['noreport', 55.6832, 12.5714], 
    ['edisikvosi', 55.678272, 12.503643,], 
    ['Sentosa', 55.713207, 12.526474,] 
    ]; 

var map = new google.maps.Map(document.getElementById('map'), { 
    zoom: 12, 
    center: new google.maps.LatLng(55.6750, 12.5687), 
    mapTypeId: google.maps.MapTypeId.ROADMAP 
}); 

var infowindow = new google.maps.InfoWindow(); 

var marker, i; 

for (i = 0; i < locations.length; i++) { 
    marker = new google.maps.Marker({ 
     position: new google.maps.LatLng(locations[i][1], locations[i][2]), 
     map: map 
    }); 

    google.maps.event.addListener(marker, 'click', (function(marker, i) { 
     return function() { 
      infowindow.setContent(locations[i][0]); 
      infowindow.open(map, marker); 
     } 
    })(marker, i)); 
} 

// Check if user support geo-location 
if (navigator.geolocation) { 
    navigator.geolocation.getCurrentPosition(function(position) { 
     var latitude = position.coords.latitude; 
     var longitude = position.coords.longitude; 
     var geolocpoint = new google.maps.LatLng(latitude, longitude); 

     var mapOptions = { 
      zoom: 8, 
      center: geolocpoint, 
      mapTypeId: google.maps.MapTypeId.HYBRID 
     } 
     // Place a marker 
     var geolocation = new google.maps.Marker({ 
      position: geolocpoint, 
      map: map, 
      title: 'Your geolocation', 
      icon: 'http://labs.google.com/ridefinder/images/mm_20_green.png' 
     }); 
    }); 
} 
} 
google.maps.event.addDomListener(window, 'load', initialize);​

使用map.setCenter。

..... 
navigator.geolocation.getCurrentPosition(function(position) { 
     var latitude = position.coords.latitude; 
     var longitude = position.coords.longitude; 
     var geolocpoint = new google.maps.LatLng(latitude, longitude); 
      map.setCenter(geolocpoint);//line added for setting center
