如何根据 ArcGis 要素图层中的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
});

我只能通过这种方式获取过滤器数据，但我想在图层上应用过滤器。

您需要使用 FeatureLayerView.filter which will require some additional wiring when adding the FeatureLayer to the map I'm assuming youa re using a MapView though similar functionality exists for scenes. You have a large number of options in defining the spatial relationship of the filter. See the documentation on the spatialRelationship 属性的 FeatureFilter

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
    });
