identify

I use identify to identify feature when click on map:

import * as identify from "@arcgis/core/rest/identify.js";

view.on("click", (event: ViewClickEvent) => {

const params = new IdentifyParameters({

geometry: event.mapPoint

// .....

});

identify.identify(url, params);

});

Is it possible to know a feature that is already identified, so that identify.identify won't be called when clicked on it again?

When I click on it again, I want show it's popup.

Thanks.

I got a solution: use hitTest

view.on("click", (event: ViewClickEvent) => {

view.hitTest(event).then(({ results }) => {

if (results.length == 0) {

const params = new IdentifyParameters({

geometry: event.mapPoint

// .....

});

identify.identify(url, params);

}

});

});
