如何在地图中的HTML 5中显示自定义弹出窗口？下面是我的代码，显示当前位置和精确定位相同。当我点击精确定位时如何显示弹出窗口。

提前致谢。

<!DOCTYPE html>
<html>
<body>
<!--<button onclick="getLocation()">Try It</button>-->
  <div id="mapholder"></div>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script>
  getLocation();
  var x=document.getElementById("demo");
  function getLocation() {
    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(showPosition,showError);
    } else{
      x.innerHTML="Geolocation is not supported by this browser.";
    }
  }
  function showPosition(position) {
    lat=position.coords.latitude;
    lon=position.coords.longitude;
    latlon=new google.maps.LatLng(lat, lon)
    mapholder=document.getElementById('mapholder')
    mapholder.style.height='500px';
    mapholder.style.width='1000px';
    var myOptions={
      center:latlon,
      zoom:14,
      mapTypeId:google.maps.MapTypeId.ROADMAP,
      mapTypeControl:false,
      navigationControlOptions:{
        style:google.maps.NavigationControlStyle.SMALL
      }
    };
    var map=new google.maps.Map(document.getElementById("mapholder"),myOptions);
    var marker=new google.maps.Marker(
      {position:latlon,map:map,title:"You are here!"}
    );
  }
  function showError(error) {
    switch(error.code) {
      case error.PERMISSION_DENIED:
        x.innerHTML="User denied the request for Geolocation.";
        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:
        x.innerHTML="An unknown error occurred.";
        break;
    }
  }
</script>
</body>
