Question

我认为这应该很简单，但我尝试的每件事都行不通。我想要做的是添加隐藏标记的代码（如果设置了review参数）。不幸的是，使用Gmaps4Rails V2，我无法隐藏所有标记。

<script src="//maps.google.com/maps/api/js?v=3.13&amp;sensor=false&amp;libraries=geometry" type="text/javascript"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js' type='text/javascript'></script>

<script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.6.0/underscore.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/gmaps4rails/2.1.2/gmaps4rails.js"></script>



</div>

<div style='width: 100%;'>
  <div id="map" style='width: 100%; height: 400px;'></div>
</div>

<script type="text/javascript">
handler = Gmaps.build('Google');
handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
  if(navigator.geolocation)
    navigator.geolocation.getCurrentPosition(displayOnMap);
  markers = handler.addMarkers (<%=raw @hash.to_json %>);

  handler.bounds.extendWith(markers);
  handler.fitMapToBounds();



 _.each(markers, function(index){
   markers[index].hide();
  });


  function displayOnMap(position){
   homepostion = handler.addMarker({
    lat: position.coords.latitude,
    lng: position.coords.longitude
  });
  handler.map.centerOn(homepostion);
};
});

</script>

一如既往地谢谢你

您从addMarker获得的所有标记都包含show和hide个函数see code

如果您使用群集器，这是另一个故事，请从removeMarker function

中获取灵感
