We need to build a kind of popup, but completely custom made. I need specific fields that I get from the feature layer by using the PopupTemple:   for (var i = 0; i < featurelayer.popupTemplate.fieldInfos.length; i++) { var fieldname = featurelayer.popupTemplate.fieldInfos[i].fieldName; }   Important is the sort order of the fields and for most feature layers the sort order is the same as set in the AGOL portal. When I use the standard ESRI popup, view.popup, the sort order is for most maps the same, and follows the AGOL portal setting. On some maps I have a different sort order. The sort order in the AGOL portal is the same as the sort order in view.popup, but different in my 'feature layer.popupTemplate.fieldInfos'. I cannot find the reason why it is sometimes different. Any ideas? How can I get the correct AGOL sort order information so I can manage to sort myself instead of following the fieldInfos array natural sort order? ... View more

Working with the old Webmapviewer in AGOL, I was able to create a popupTemplate. I used the information from this popupTemplate to draw the content of my custom fields based on the visibility flag, using the Javascript API. for (var i = 0; i < featurelayer.popupTemplate.fieldInfos.length; i++) {    if (featurelayer.popupTemplate.fieldInfos[i].visible)) {       "draw field "    } }   The new Webmapviewer provides a way to define a form, with extra options like 'allow edit' and the sort order of the fields. Can I request this information in the Javascript API and how should this be done?   ... View more

My Track implementation has the gotoOverride set to a function. I need this because I want to keep the zoom level the same as the view. Without gotoOverride set to a function that changes the zoom, Track will always zoom deep to the position you are at. I have some HTML INPUT fields, where I want to enter data. If Track is running, and I want to enter data in the INPUT field (keyboard is up), the keyboard on iOS and Android slides down when Track function provides a new coordinate.  When I remove this line out of my code:   return view.goTo(options.target); , the keyboard stays on the screen but, logically, I miss the 'not zoom' function. How can this be solved? Here is my code:   var track = new Track({ view: view, goToOverride: function(view, options) { options.target.scale = view.scale; return view.goTo(options.target); }, geolocationOptions: { maximumAge: 0, timeout: 15000, enableHighAccuracy: true }, graphic: new Graphic({ symbol: { type: "simple-marker", path: "M 14 -22 L 23.5 0 L 14 -5 L 5.5 0 z", color: "#005e96", outline: { color: "#AAAAAA", width: 0.75 }, size: 15 }, }), useHeadingEnabled: false // Don't change orientation of the map }); view.ui.add(track, "top-left");     ...

view.on("click", function(event){ view.hitTest(event.screenPoint) .then(function(response){ if (response.results.length > 0) { <code> } } });​ This piece of code fires when I touch the view. When the view is zoomed in to a very 'deep' level, sometimes a touch on the screen does not give a hit on the graphic. The user has clicked a little to much to the side or above/under the graphic. Is there a way to expand the 'hit buffer', the area around the graphic where this routine fires? Thanks   ... View more

Used to pass a graphic into Applyedits to update an Attribute. The code below works with API version 4.16, but fails in 4.18. In 4.18 I have to query for the feature and than pass it into my updatefeature function. Is this an error or did I miss a change in 4.17 or 4.18 API? function updatefeature(graphic, layer) { graphic.attributes.Status = "1"; const edits = { updateFeatures: [graphic] }; applyEdits(edits,layer); }     function applyEdits(params,layer) {       layer         .applyEdits(params)         .then(function(editsResult) {         if (           editsResult.addFeatureResults.length > 0 ||           editsResult.updateFeatureResults.length > 0         ) {           let objectId;           objectId = editsResult.addFeatureResults[0].objectId;         else if (editsResult.deleteFeatureResults.length > 0) {         }       })         .catch(function(error) {         errormessage("ArcGIS applyEdits error", error.code + ' | ' + error.name + ' | ' + error.message);       });     }   Thanks ...

I know how to change the value of an attribute with the Javascipt API. I use Applyedits(). Now I need to create a new attribute, that has no representation in the Featurelayer in AGOL, through ApplyEdits.  When I try this ApplyEdits, the function approves the action, but the newly created attributes are not added to the Featurelayer. How should this be done?  ... View more

I have a webpage with a map view filled with features. I need to generate a report in PDF from this webpage, with a PDF-page for every feature. On top of the page, I need a zoomed-in image of the feature on a map. What's the best way to achieve this? I am able to  zoom to the features with Javascript commands so I could iterate over all of them and make separate screenshots. But this zooming process takes some time, and would take a lot of time when there are 100+ features. Is there another way? I read about resquesting images from a server. Is there a good example that sets me in the right direction? Thank you. ... View more
