在AngularJS中如何使用谷歌地图把当前位置显示出来

<map-geo-location height="400" width="600"></map-geo-location>
<script src="angular.js"></script>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script src=="mapGeoLocation.js"></script>

(function(){
var mapGeoLocation = ['$window', function($window){
var template = '<p><span id="status">正在查找地址...</span></p>' + '<br /><div id="map"></div>',
mapContainer = null,
status = null;
function link(scope, elem, attrs){
//以Angular的方式获取Angular元素
status = angular.element(document.getElementById('status'));
mapContainer = angular.element(document.getElementById('map'));
mapContainer.attr('style', 'height:' + scope.height + 'px;width:' + scope.width + 'px');
$window.navigator.geolocation.getCurrentPosition(mapLocation, geoError);
}
//定位成功时调用
function mapLocation(pos){
status.html('found your location! Longitude: ' + pos.coords.longitude + ' Latitude: ' + pos.coords.latitude);
var latlng = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
var optons = {
zoom:15,
center: latlng,
myTypeCOntrol: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(mapContainer[0], options);
var marker = new google.maps.Markser({
position: latlng,
map: map, 
title: "Your location"
});
}
//定位失败时调用
function geoError(error){
status.html('failed lookup ' + error.message);
}
return {
restrict: 'EA', //默认
scope:{
height: '@',
width:'@'
},
link: link,
template: template
}
}];
angular.module('direcitveModule',[])
.direcitve('mapGeoLocation', mapGeoLocation);
}());
