I am having a problem updating a feature layer data using applyEdits function. I looked at the sample code in applyEdits API reference and Sandbox sample code, but I haven't been able to figure it out how to update the data. I am only interested in updating existing data attributes. I would very much appreciate your help.
require([
"esri/Map",
"esri/views/SceneView",
"esri/layers/FeatureLayer",
"esri/geometry/Extent",
'esri/geometry/ScreenPoint',
'dojo/_base/lang',
"dojo/on",
"dojo/dom",
"dojo/domReady!"
],
function (
Map, SceneView, FeatureLayer, Extent, ScreenPoint, lang, on, dom
) {
var lyrUrl = 'https://services1.arcgis.com/aT1T0pU1ZdpuDk1t/arcgis/rest/services/CALO_survey_web/FeatureServer/0';
var map = new Map({
basemap: 'satellite'
});
var initialExtent = new Extent({
xmin: -8520399.50094139,
xmax: -8466523.75224205,
ymin: 4109431.55147233,
ymax: 4173688.01969221,
spatialReference: 102100
});
var featureLyr = new FeatureLayer({
url: lyrUrl
});
map.add(featureLyr);
var sceneView = new SceneView({
container: 'map',
map: map,
extent: initialExtent
});
var _onclick = function (evt) {
var s = new ScreenPoint({
x: evt.x,
y: evt.y
});
sceneView.hitTest(s).then(picked => {
console.log(picked);
if (picked.results[0].graphic) {
var editFeature = picked.results[0].graphic;
editFeature.attributes.YearBuilt = '2000';
console.log('after edit', editFeature);
var edit = {
updateFeatures: [editFeature]
};
var promise = featureLyr.applyEdits(edit);
console.log(promise);
}
});
}
sceneView.on('click', _onclick);
