Question

我的双击事件不起作用，当我双击标记时，它不会删除。请帮忙：）。这是我的代码。 :)我已经尝试通过编辑一些东西来修复它，但似乎没有工作。

function addMarker(location) {
  marker = new google.maps.Marker({
    position: location,
    map: map
  });

  google.maps.event.addListener(marker, 'dblclick', 
    // closure so the callback remembers the marker
    (function(what){
      return function() {
        what.setMap(null);
        // you might want to remove it from markersArray here too
      };
    )(marker)
  );
  });

  markersArray.push(marker);
}
