Is there a finished drawing event or callback in the Google Maps API v3?

Question

我想在地图上加载东西时弹出一个加载栏。

Answer 1

  // insert / show your loading bar
  // (or not if it's already visible in the DOM)

  // var map = new google.maps.Map(map_canvas, map_options);

  google.maps.event.addListenerOnce(map, 'idle', function() {
    // hide your loading bar
  });
