Hi guys I am trying to select polygon features using sketchViewModel, using this sample code. I removed CSV layer with FeatureLayer. But now, when i select features, in table i see only OBJECTID, it applies column headers for other fields, but without data. see Pic. for error and Code below. Thank you in advance. <!DOCTYPE html>

Hi all, I have created feature table using pure java script CRUD, using hitTest i get my features attributes in table when i click on features on map. Also i did it using fetch, so if have any idea to use fetch URL will be useful. Now i want to update selected features attributes at the same time, like we can on desktop version select column, enter value hit enter or click and update selected features values. I know, i have to use Apply Edits, but how to update multiple features attributes at the same time. Any help appreciated. Thank you

Robert, Thank you very much for help. I do not kmow if i have to open new question. but i ask here and if needed i will open new question. When adding new features from one to another layer using this code, one field has same name and it values adds automaticaly from source layer (Layer2) to target layer (featureLayer). So i tried to add attributes with same name to graphics (pfeatures) as it has target layer (featureLayer)(e.g. field name "Req_Code") and add value e.g. "REQ-123", but it does not applies. in console.log it returns -, Req_Code: REQ-123". Code: pfeatures = results.features.map(function(graphica) {
graphica.symbol = {
type: "simple-fill", // autocasts as new SimpleFillSymbol()
color: "cyan",
style: "solid",
outline: { // autocasts as new SimpleLineSymbol()
color: "black",
width: 1
},
};
pfeatures.attributes{
Req_Code:"REQ-123"
}
console.log(pfeatures)

Robert, I see I changed my code, now it applies empty attributes without geometry. Also if i do not mistake i already have defined graphic here (see row 24), can i use it for update graphics layer? if so, how? If no: How can i call "create-complete" for addGraphic? From this Query? "var query = HWLayer.createQuery();" tell me how please. P.S. Sorry for my bad skills, i study JavaScript myself and sometimes it is hard to connect some portion of code to next part. Thank you for your help, i really appreciate. view.on("click", function (event) {
view.hitTest(event).then(function (response) {
if (response.results.length) {
var graphic = response.results.filter(function (result) {
// check if the graphic belongs to the layer of interest
return result.graphic.layer === layer2;
})[0].graphic;
var attributes = graphic.attributes;
var name = attributes.Req_Code; }
var queryZebna = dom.byId("query-Zebna");
on(queryZebna, "click", function() {
queryMagistraluri()
.then(displayResults);});
function queryMagistraluri() {
var query = HWLayer.createQuery();
//query.returnGeometry = true;
//query.outFields = ["*"];
query.where = "Req_Code IS NULL";
query.outSpatialReference = view.spatialReference;
return HWLayer.queryFeatures(query)}
// display the query results in the view
function displayResults(results) {
console.log(results);
var pfeatures = results.features.map(function(graphica) {
graphica.symbol = {
type: "simple-fill", // autocasts as new SimpleFillSymbol()
color: "cyan",
style: "solid",
outline: { // autocasts as new SimpleLineSymbol()
color: "black",
width: 1
},
};
return graphica
});
graphicsLayer.addMany(pfeatures);
console.log(graphicsLayer)
// Apply Edits აქ მუშაობს, მაგრამ მხოლოდ ამატებს ატრიბუტებს.
const edits = { //Fire the addFeatures function using the completed graphic
addFeatures: [graphicsLayer]
};
applyEdits(edits);

Thanks Robert, we will get latest version of ArcGIS Server soon and i will transfer all data an after that i will try again. Before that, i am trying to complete another task, i wanted to start working on that after "adding new polygon feature", but i try it before new ArcGIS Server. Take a look it please and help : https://community.esri.com/message/904126-updates-graphicsgraphicslayer-to-feature-layer-use-applyedits . Thank you.
