iPhone谷歌地图API V3用户当前位置和展示餐厅

我想使用谷歌API V3来显示您的当前位置和附近的餐馆或咖啡馆的网站.. 我试过这个代码在谷歌的教程，但我不能得到这个api会显示我在地图上的当前位置这里是代码：有一个pyrmont，我可以改变它与另一个经度和纬度，但我不能使它与navigator.geolocation.getCurrentPosition（）有用; 感谢iPhone谷歌地图API V3用户当前位置和展示餐厅

，我知道有这样的代码：但我不知道如何使用获得位置出来吧......

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=true&libraries=places"></script> 

<script type="text/javascript"> 
    var map; 
    var infowindow; 

if (navigator.geolocation) { 
     navigator.geolocation.getCurrentPosition(success, error); 
    } else { 
     alert('geolocation not supported'); 
    } 

    function success(position) { 
     alert(position.coords.latitude + ', ' + position.coords.longitude); 
    } 

    function error(msg) { 
     alert('error: ' + msg); 
    } 

    function initialize() { 
    var pyrmont = new google.maps.LatLng(48.195201,16.369547); 

    map = new google.maps.Map(document.getElementById('map'), { 
     mapTypeId: google.maps.MapTypeId.ROADMAP, 
     center: pyrmont, 
     zoom: 15 
    }); 

    var request = { 
     location: pyrmont, 
     radius: 500, 
     types: ['cafe'] 
    }; 
    infowindow = new google.maps.InfoWindow(); 
    var service = new google.maps.places.PlacesService(map); 
    service.search(request, callback); 
    } 

    function callback(results, status) { 
    if (status == google.maps.places.PlacesServiceStatus.OK) { 
     for (var i = 0; i < results.length; i++) { 
     createMarker(results[i]); 
     } 
    } 
    } 

    function createMarker(place) { 
    var placeLoc = place.geometry.location; 
    var marker = new google.maps.Marker({ 
     map: map, 
     position: place.geometry.location 
    }); 

    google.maps.event.addListener(marker, 'click', function() { 
     infowindow.setContent(place.name); 
     infowindow.open(map, this); 
    }); 
    } 

    google.maps.event.addDomListener(window, 'load', initialize); 
</script>

编辑。

因此，搜索功能在我的实际位置上返回零结果，所以当我偏移我的实际位置以更接近您的原始位置（因为我不知道匹配您的查询的结果密度）对我而言。你必须编辑6.6和89.45看到它的工作，但那么你就需要做一些与搜索本身，如果你希望它是有用的

那么我该怎么处理这条线呢？ var pyrmont = new google.maps.LatLng（48.195201,16.369547）; – xmux

它不工作，如果我不改变这个pyrmont，它仍然只显示相同的位置..不somewhereelse .. – xmux

当我运行它，我得到您的搜索结果和我的位置。您的目标是在用户位置周围搜索？ –

代码在前面的例子不工作，我修改了一些代码，我希望这会有所帮助。
