如何在ArcGis Feature图层中基于多个图形几何过滤数据？

Question

这是我的代码。

let query = layer.createQuery();
query.geometry = geometry_here;
query.outFields = ["*"];
query.returnGeometry = true;

layer.queryFeatures(query).then((result) => {
    console.log('result of principle transmission layer', result);
    // i get filtered result here but i want to apply direct on layer
});

我只是通过这种方式获取过滤器数据，但是我想在层上应用过滤器。

将FeatureLayer添加到地图时，您需要使用FeatureLayerView.filter，这将需要一些额外的接线。我假设您正在重新使用MapView，尽管场景中存在类似的功能。在定义过滤器的空间关系时，您有很多选择。请参阅FeatureFilter的spatialRelationship属性上的文档

const view = new MapView({
   container: "sceneDiv",
   map: map,
   center: [-73.95, 40.702],
   zoom: 13,
   padding: {
     right: 300
   }
});
var layer = new FeatureLayer(url);

map.add(layer);

view.whenLayerView(layer)
    .then(function(layerView) {
      // The layerview for the layer is available here
      featureLayerView.filter = new FeatureFilter({

          geometry: geometry_here,
          spatialRelationship: "contains"
      });
    })
    .catch(function(error) {
      // An error occurred during the layerview creation
    });
