Get the ID of graphics on featureLayer

Anonymous User — Tue, 12 Oct 2021 23:12:44 GMT

I have a feature layer that is not preselected on map load and I want to get the ID of a point on the map when I click on it, on a certain point. Further on, I'll get that ID and send it to a backend method for further data processing.

My question is how do I get the ID of a point on the map when I click on it? How do I always get the ID with each new click on a different point?

First click on 2, get the ID. Then click on 1, get the ID, etc.

I tried something like this

disLayer = new FeatureLayer({ title: restService.label, url: restService.restServiceLink, outFields: ["*"], // Return all fields so it can be queried client-side popupTemplate: { // Enable a popup title: "<b>" + restService.label + ": {" + restService.searchAndPopupFieldName + "} </b>", content: photoContentHtml } }); map.add(disLayer, 0); on(disLayer, 'click', function (e) { console.log("e", e); });

I wanted to see what 'e' contains, but I can't print it out. The on click event doesn't work and it's not printing e. How do I get the ID of a point on map when I click the point?

Hi @Anonymous User ,

Please refer to this sample this will provide you some reference to get the attributes for the clicked feature on the map.

https://developers.arcgis.com/javascript/latest/sample-code/view-hittest/

What you have in your code snippet, will return object only, you will need to further modify the code to get attributes.

Hope this helps.
