I have several hosted feature services already published to ArcGIS Online. I know I can download them, add a global ID in Arc Map then republish. Is it possible to add a global ID directly to a hosted feature service?

Perfect! Thanks! After looking at your code it appears the reason mine wasn't working was because the layers wasn't loaded yet. Nice trick with the .toJson. That is really handy!

I struggling copying the Object out of my console. Below is what I get when I right-click the Object in the Chrome browser and copy it.

Oops. Is there a way I can change where this is posted, or should I just create a new post over there?

‎04-28-2015

Seems like this should be simple, but I'm stumped. I want to modify this sample to output to the console the list of fields for the loaded FeatureLayer. See below. The only modification I made was to add line 65: console.log(states); That works fine, and shows there is attribute called "fields" for the layer states. However, on the next line when I try log console.log(states.fields); it says it is undefined. Why? And the bigger question, how do I get the list of fields? <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no"> <title></title> <link rel="stylesheet" href="https://community.esri.com//js.arcgis.com/3.13/esri/css/esri.css"> <style> html, body, #map { height: 100%; width: 100%; margin: 0; padding: 0; } </style> <script src="//js.arcgis.com/3.13/"></script> <script> var map; require([ "esri/map", "esri/geometry/Extent", "esri/layers/FeatureLayer", "esri/symbols/SimpleLineSymbol", "esri/symbols/SimpleFillSymbol", "esri/symbols/TextSymbol", "esri/renderers/SimpleRenderer", "esri/layers/LabelLayer", "esri/Color", "dojo/domReady!" ], function( Map, Extent, FeatureLayer, SimpleLineSymbol, SimpleFillSymbol, TextSymbol, SimpleRenderer, LabelLayer, Color ) { // load the map centered on the United States var bbox = new Extent({"xmin": -1940058, "ymin": -814715, "xmax": 1683105, "ymax": 1446096, "spatialReference": {"wkid": 102003}}); map = new Map("map", { extent: bbox }); var labelField = "STATE_NAME"; // create a renderer for the states layer to override default symbology var statesColor = new Color("#666"); var statesLine = new SimpleLineSymbol("solid", statesColor, 1.5); var statesSymbol = new SimpleFillSymbol("solid", statesLine, null); var statesRenderer = new SimpleRenderer(statesSymbol); // create a feature layer to show country boundaries var statesUrl = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/3"; var states = new FeatureLayer(statesUrl, { id: "states", outFields: [labelField] }); states.setRenderer(statesRenderer); map.addLayer(states); console.log(states); console.log(states.fields); // create a text symbol to define the style of labels var statesLabel = new TextSymbol().setColor(statesColor); statesLabel.font.setSize("14pt"); statesLabel.font.setFamily("arial"); var statesLabelRenderer = new SimpleRenderer(statesLabel); var labels = new LabelLayer({ id: "labels" }); // tell the label layer to label the countries feature layer // using the field named "admin" labels.addFeatureLayer(states, statesLabelRenderer, "{" + labelField + "}"); // add the label layer to the map map.addLayer(labels); }); </script> </head> <body> <div id="map"></div> </body> </html>

Thanks! he ArcGIS REST API definitely looks like the best option for me!

‎02-17-2015

I am collecting user data on my website. I want to take that data and update the attribute of a singel feature in a hosted feature service. I am an authenticated user and I know the URL of the hosted features service and GlobalID of the actual feature, but I'm know sure how to go about pushing the updated data. I'm using the Javascript API and Python on my server.

‎06-09-2014

The solution I found was the CIRCLE class. Below is the code I used. _addGraphic: function(pt, accuracy) { var circleSymb = new SimpleFillSymbol( SimpleFillSymbol.STYLE_SOLID, new SimpleLineSymbol( SimpleLineSymbol.STYLE_SOLID, new Color([27, 95, 248,0.75]), 1 ), new Color([27, 95, 248,0.20]) ); var radius = accuracy; var circle = new Circle({ center: pt, geodesic: true, numberOfPoints: 120, radius: radius, radiusUnit: "esriMeters" }); this.halo = new Graphic(circle, circleSymb); map.graphics.add(this.halo); } showLocation: function(location) { //zoom to the users location and add a graphic var pt = new Point(location.coords.longitude, location.coords.latitude); if ( !this.graphic ) { this._addGraphic(pt, location.coords.accuracy); } }

‎05-30-2014

Noah, Thanks for the reply. I looked at the Geolocation API Specification and now have the current accuracy using: location.coords.accuracy Now, how do I draw the halo to have a certain radius? This example uses SimpleMarkerSymbol to draw the GPS point and halo. The only problem is the units are in pixels. Is there a way draw a circle graphic with a certain radius (in feet)? Thanks!

‎05-30-2014

Does anyone have a working example where you show the current GPS location by adjusting the halo around the GPS point? Here is an example using Openlayers: http://openlayers.org/dev/examples/geolocation.html I'm having a hard time figuring out how to do the equivalent using Esri javascript. Thanks!

‎11-11-2013

I would like to draw a sketch using graphics (see this example) and save to a feature service. Any thoughts on how to take the entire sketch (all graphics) and save to feature service?

‎09-30-2013

Any update on this?

‎09-25-2013

That is exactly what I was looking for. Thanks! I didn't think it could be so easy. I just added one line of code: myLayer.setDefinitionExpression("attName= 'att'");

‎09-25-2013

I would like to be able to show/hide features based on their attribute data. Does anyone have a sample of something similiar? Can you point me in a direction to investigate?

‎09-24-2013

Thanks Ben! That did the trick. I copied that code from the Esri example. I wonder why there are three ='s in that example. Maybe that is why it doesn't work in that example. Either way, you helped me. Thanks again!
