Hi guys, I have four layers ( names: csvLayer, csvLayer1, csvLayer2, csvLayer3) on my map which have same fields and i have custom html table where i add features selected on map using polygon, but i can add features only from one layer, which is selected in code. In this code i can path one layer, but how can i path all four layers to select features from them? Here is code i use for selecting fatures: let features = []; let csvLayerView; csvLayer.when(() => { view.whenLayerView(csvLayer).then(function (layerView) { csvLayerView = layerView; }); }) .catch(errorCallback); // polygonGraphicsLayer will be used by the sketchviewmodel // show the polygon being drawn on the view const polygonGraphicsLayer = new GraphicsLayer(); map.add(polygonGraphicsLayer); // add the select by rectangle button the view //view.ui.add("select-by-rectangle", "top-left"); const selectButton = document.getElementById("select-by-rectangle"); // click event for the select by rectangle button selectButton.addEventListener("click", () => { view.popup.close(); sketchViewModel.create("polygon"); }); // add the clear selection button the view //view.ui.add("clear-selection", "top-left"); //document.getElementById("clear-selection").addEventListener("click", () => { //featureTable.clearSelection(); //featureTable.filterGeometry = null; //polygonGraphicsLayer.removeAll(); //}); // create a new sketch view model set its layer const sketchViewModel = new SketchViewModel({ view: view, layer: polygonGraphicsLayer }); // Once user is done drawing a rectangle on the map // use the rectangle to select features on the map and table sketchViewModel.on("create", async (event) => { if (event.state === "complete") { // this polygon will be used to query features that intersect it const geometries = polygonGraphicsLayer.graphics.map(function(graphic){ return graphic.geometry }); const queryGeometry = await geometryEngineAsync.union(geometries.toArray()); selectFeatures(queryGeometry); } }); // This function is called when user completes drawing a rectangle // on the map. Use the rectangle to select features in the layer and table function selectFeatures(geometry) { if (csvLayerView) { // create a query and set its geometry parameter to the // rectangle that was drawn on the view const query = { geometry: geometry, outFields: ["*"] }; // query graphics from the csv layer view. Geometry set for the query // can be polygon for point features and only intersecting geometries are returned csvLayerView.queryFeatures(query) .then((results) => { //const raro = []; if (results.features.length === 0) { clearSelection(); } else { // მონიშნული ობიექტებისთვის მონაცემების წამოღება და ცხრილში ასახვა results.features.forEach((feature)=>{ var tablemili = document.getElementById("tablemili"); newRow = tablemili.insertRow(tablemili.length), cell1 = newRow.insertCell(0), cell2 = newRow.insertCell(1), cell3 = newRow.insertCell(2), cell4 = newRow.insertCell(3), cell5 = newRow.insertCell(4), cell1.innerHTML = feature.attributes["milis_ID"]; cell2.innerHTML = feature.attributes["diametri"]; cell3.innerHTML = feature.attributes["dasaxeleba"]; cell4.innerHTML = feature.attributes["masala"]; cell5.innerHTML = feature.attributes["qselis_kategoria"]; }); polygonGraphicsLayer.removeAll(); } }) .catch(errorCallback); } } function errorCallback(error) { console.log("error happened:", error.message); } ...
