Acquisition of attribute data for MVT data

TakahiroKAMIYA — Wed, 10 Feb 2021 09:48:40 GMT

Hi,

As for the attribute data of MVT data, in Mapbox GL JS, I can get it as follows, but can't I get it in ArcGIS API for JavaScript?

map.on("click", "japan_ver821_layer", (e) => { const value = e.features[0]; console.log(value) new mapboxgl.Popup() .setHTML(`<b>${value.properties.KEN}</b>${value.properties.SIKUCHOSON}`) .setLngLat(e.lngLat) .addTo(map); });

The code we used is shown below.

Are you trying to get back data from the GeoJson layer?

Q: Maybe try this?

const opts = { include: geoJSONLayer };

Thank you very much.
No, I want to get the data from the following vector tile.

const tileLayer = new VectorTileLayer({ title: "National City Boundary Data (Vector Tile)", url: ". /style.json", opacity: 0.5 });

I understand how to get attribute data from GeoJSON.
