How to add popups to MapImageLayer (JavaScript API 4.0 esri)

Question

I have to create a web map application with webservices (WMS or WFS).

I use the API for JavaScript of ESRI (4.0) and MapImageLayers for my data. But I didn't find how to add popups (or "popupTemplate"= to a MapImageLayer.

I use this sample for my code (https://developers.arcgis.com/javascript/latest/sample-code/sandbox/sandbox.html?sample=layers-mapimagelayer-sublayers)

Answer 1

You can use identifyTask to configure the popupTemplate for each sublayer of your MapImageLayer. See the following sample: IdentifyTask JSAPI 4.0

Answer 2

so far, no way to do it. MapImagerLayer, popupTemplate would not work, ESRI have NOT yet fix this bug,

all I get is empty

identifyTask
                       .execute(params)
                       .then(function(response) {


                         var results = response.results;

                         console.log('identify-results: ', results)


                         return results.map(function(result) {
                                                                var feature = result.feature;
                                                                var layerName = result.layerName;

                                                                feature.attributes.layerName = layerName;



                                                                  feature.popupTemplate = {
                                                                    // autocasts as new PopupTemplate()
                                                                    title: layerName,
                                                                    content: "{*}",
                                                                    outFields: ["*"]
                                                                  };

                                                                return feature;
                         });
                       })
                       .then(showPopup); // Send the array of features to showPopup()
