我的代码

＆＃13;

var map, GeoMarker;

function initialize() {
  var mapOptions = {
    zoom: 17,
    center: new google.maps.LatLng(-34.397, 150.644),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'),
    mapOptions);

  GeoMarker = new GeolocationMarker();
  GeoMarker.setCircleOptions({
    fillColor: '#808080'
  });

  google.maps.event.addListenerOnce(GeoMarker, 'position_changed', function() {
    map.setCenter(this.getPosition());
    map.fitBounds(this.getBounds());
  });

  google.maps.event.addListener(GeoMarker, 'geolocation_error', function(e) {
    alert('There was an error obtaining your position. Message: ' + e.message);
  });

  GeoMarker.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);

if (!navigator.geolocation) {
  alert('Your browser does not support geolocation');
}


$('#large-dialog').on('shown.bs.modal', function(e) {
  initialize();
});
