I know I can get feature layer attributes using Query class, but is there another way to get all attributes in a feature layer?
Ah. that make sense now. Here is a 4.2 version of the sample:

Hi Robert,
I am using JavaScript API 4.2.
Makiko,
I am not sure whats going wrong in your code then. Here is a full example of using esriRequest:

I tested your code, but it gave me an error. This is not a big deal so I fixed it and tried it again. But it still doesn't give me any response. Though, the example code that uses GeoJson works fine. I wonder what is the problem with the feature service layer.
You absolutely can use an esriRequest on things other then GeoJSON.

Hi Saroj and Robert,
Thank you so much for your quick response. There is no special reason not using QueryTask class. Since I need all attributes in a feature layer in JSON format so I thought it might have something other than QueryTask class that gives me direct access to JSON formatted attributes.
esriRequest seems to be the answer for my question, but does it work on a feature service layer? I looked at the example and replaced url to feature service layer, but it didn't return anything. Does esriRequest only work for GeoJson layer?
var url = "https://services.arcgis.com/.../arcgis/rest/services/.../FeatureServer/0"esriRequest(url, {responseType: "json"}).then(function(response){// The requested dataconsole.log(response);var dataJson = response.data;console.log(dataJson)});
Thank you,
Makiko
Hmm.. any particular reason why? The QueryTask is the main JS API route to get attribute values. The other way would be to just use a esriRequest directly to the map service to get the attribute values for a know ObjectID.
Do you want to display attributes of a feature layer as a Popup Window? If yes, then check this sample out.
