Get value of an attribute from GraphicsLayer

I am adding a GraphicsLayer with markers on the map and need to know which marker was clicked. How do I get a value of an attribute when I click on the marker? Thank you

hitTest() will return features from an intersecting GraphicsLayer, from which you can getAttribute() or browse with the attributes property.

Here are some hitTest() samples to check out.

You can use this code to get your Markertype

view.on('click',(event) =>{ view.hitTest(event) .then((response) =>{ console.log(response.results[0].graphic.attributes.MarkerType); //or attributes['MarkerType']; }); });
