Question

我正在使用L.GeoJSON.AJAX来加载我的json。我有以下样式来标记标记：

    var weakClusterMarkerOptions = {
      radius: 5,
      fillColor: "#FFFF00",
      color: "#000",
      weight: 2,
      opacity: 1,
      fillOpacity: 0.8
    },
    strongClusterMarkerOptions = {
      radius: 7,
      fillColor: "#CC0000",
      color: "#CC0000",
      opacity: 1,
      fillOpacity: 0.8
    };

  function customizeClusterIcon(feature, latlng) {
    if (feature.properties.strongCl === 'strong') {
      return L.circleMarker(latlng, strongClusterMarkerOptions);
    } else {
      return L.circleMarker(latlng, weakClusterMarkerOptions);
    }
  }

然后我使用以下内容进行过滤：

function toggleStrength(strength, showLayer) {
    jsonLayer.refilter(function (feature, layer) {
      if (strength == 'all') {
        return true;
      } else {
        if (showLayer) {
          return feature.properties.strongCl === strength;
        }
      }
    });
  }

这里的问题是，当我过滤circleMarker的边框消失但标记仍然可见时，特别是填充颜色。

所以我最终为每种条件（弱和强）创建了LayerGroups，然后根据过滤器清除并添加了相应的组。

 public Output getClaimsFromAPI(@NonNull final Input xyzInput)
            throws PermanentException, TransientException {
            final Response res = fetchHealBeamServiceResponse(webTarget, xyzInput);
            Object respondentMapObject;
            Map<String, Map> mapEntityFromResponse = res.readEntity(Map.class);
            if (mapEntityFromResponse != null) {
                respondentMapObject = mapEntityFromResponse.get(ServiceConstants.MAP_KEY);
                return getOutputFromResponseMap(respondentMapObject, xyzInput);
            } else {

              throw new RuntimeException("The response returned does not contain map");
            }
    }


private Response fetchHealBeamServiceResponse(WebTarget healBeamTarget,
                                                  Input xyzInput)
            throws PermanentException, TransientException {
        Response res = null;
        try {
            res = healBeamTarget
                    .path(HealBeamServiceConstants.GET_CUSTOMER_PATH)
                    .register(Configurator.getSoaOpNameFeatureForCustomerResource())
                    .resolveTemplate(ServiceConstants.ID, xyzInput.getId())
                    .request(MediaType.APPLICATION_JSON_TYPE)
                    .property(HealBeamServiceConstants.SERVICE_KEY, SOA_SERVICE_NAME)
                    .property(HealBeamServiceConstants.OPERATION_KEY, SOA_OP_NAME_GET_CUSTOMER)
                    .acceptLanguage(java.util.Locale.getDefault())
                    .get();
            if (Response.Status.REQUEST_TIMEOUT.getStatusCode() == res.getStatusInfo().getStatusCode()) {

                throw new TransientException("Request timed out with status" + res.getStatusInfo().getStatusCode());
            } else if (Response.Status.OK.getStatusCode() != res.getStatusInfo().getStatusCode()) {
          log.error("Some Error"):
            }
            return res;
        } catch (RuntimeException e) {

            throw new PermanentException("Unexpected Exception Occured, Exception Message " + e.getMessage());
        } finally {
            if (res != null) {
                res.close();
            }
        }
    }

您的fillColor和color具有相同的值#CC0000。可能边界就在那里。它与填充颜色相同。
