Hi All I have a map that has a sketch widget. Now I want to hide that sketch widget if a certain variable contains data and only show the map. But if that certain variable is null or empty I want the map to show the sketch widget. I am using JavaScript. I hope this question does make sense. Please advise. Kind Regards Siyabonga Kubeka

Hi Robert, When I use the suggestion above I get the following error saying that getLatitude and getLongitude are not functions.

Hi Robert, Thank you very much. One last question, is it possible to use those stored coordinates to recreate the polygon? The idea is to save a map and the polygon, so that it can be opened at another stage. If there is a way, how do I do it? Regards Siyabonga Kubeka

Hi All I am trying to get the coordinates of each vertex and separate they by putting all the latitudes on one field and all the longitudes on one field. This is who I tried to do it but it is not dong what I want it to do: for (var i = 0; i < gra.geometry.rings.length; i++){ for (var p = 0; p < gra.geometry.rings.length; p++){ crmLatitude = String(gra.geometry.rings); crmLongitude = String(gra.geometry.rings ); var LatLon = String(gra.geometry.rings ); console.log(LatLon); latlon = LatLon; } How can I do it? Please assist. Kind Regards Siyabonga Kubeka

Hi All I gave a widget that I want ti customize by removing the following items on it: 1. Draw a circle. 2. Draw a rectangle, 3. Draw a point 4. Draw a polyline. I only want the draw polygon item. How do I do that?

Hi Robert, Thank you very much.

Hi All I have the following JavaScript code that I use to retrieve province, municipality, ward no and district. Now I want to put inside its own variable, how can I do that? <script> var lon; var lat; var latlon; var provinces; var municipalities; var districts; var wards; require([ "esri/Map", "esri/views/MapView", "esri/WebMap", "esri/layers/FeatureLayer", "esri/tasks/QueryTask", "esri/tasks/support/Query", "esri/config", "esri/widgets/Sketch", "esri/layers/GraphicsLayer"], function(Map, MapView, WebMap, FeatureLayer, QueryTask, Query, esriConfig, Sketch, GraphicsLayer) { esriConfig.portalUrl = "https://portal.environment.gov.za/portal"; const featureLayerUrl = 'https://portal.environment.gov.za/server/rest/services/Boundary/Wards/MapServer/0'; var webmap = new WebMap({ portalItem: { id: "04582be14885483da48f29398960f653" } }); var graphicsLayer = new GraphicsLayer(); var view = new MapView({ map: webmap, container: "viewDiv", popup: null }); var featureLayer = new FeatureLayer({ url: featureLayerUrl }); webmap.add(featureLayer); webmap.layers.add(graphicsLayer); var sketch = new Sketch({ layer: graphicsLayer, view: view, creationMode: "update", }); view.ui.add(sketch, { position: "top-right" }); sketch.on('create', function (event) { // check if the create event's state has changed to complete indicating // the graphic create operation is completed. if (event.state === "complete") { if (view.zoom >= 11) { let gra = event.graphic.clone(); event.graphic.layer.removeAll(); gra.symbol.color = "red"; gra.layer.add(gra); console.log(view.zoom); console.log("X = ", gra.geometry.x); console.log("Y = ", gra.geometry.y); console.log("Lat = ", event.graphic.geometry.latitude); console.log("Long = ", event.graphic.geometry.longitude); lat = event.graphic.geometry.latitude; lon = event.graphic.geometry.longitude; zoomLevel = view.zoom; for (var i = 0; i < gra.geometry.rings.length; i++){ for (var p = 0; p < gra.geometry.rings.length; p++){ var LatLon = String(gra.geometry.rings ); console.log(LatLon); latlon = LatLon; } } debugger; } else{ alert("please zoom in"); event.graphic.layer.remove(event.graphic); } } }); view.on('click', function(event){ var queryTask = new QueryTask({ url: featureLayerUrl }); var query = new Query(); query.geometry = view.toMap(event); query.distance = 0; query.units = "meters"; query.spatialRelationship = "intersects"; query.returnGeometry = true; query.outFields = [ "PROVINCE", "DCS12_NAME", "S12_NAME", "WARD_NO" ]; queryTask.execute(query).then(function(results){ console.log(results.features[0].attributes); }); }); }); </script>

Hi All I am using a webmap. On it I can drop a point or draw a polygon. I can get the coordinates of the point. Now suppose I am drawing a polygon, how can I get the coordinates of each vertex?

Hi Rickey, Unfortunately I am not allowed to share the link to your webapps. But What I have also noticed is that these errors don show when I am using a .html file, but as soon as I take that code, put it on Visual Studio, this issue comes.

Hi all, I have a problem, my may displays perfectly on Microsoft Edge but it does not displays on Chrome. If it does display on Chrome it takes long to display. Sometimes it displays and does not show the SketchWidget. Or I can drop a point but I can not see it, I can only see its coordinates on Console. But all these issues don't appear on Microsoft Edge. The errors that I get on Chrome are as follows: Using ArcGIS API for JavaScript 4.15 [Date: 20200416, Revision: 43ef44a5] Failed to load resource: the server responded with a status of 404 () [https://js.arcgis.com/4.14/dojo/jquery-validation.js] outputsrc: dojoLoader output.

Hi Robert, When you look at the code, is // Create a point var point = { type: "point", longitude: 28.159843448357865, latitude: -26.374449292814024 }; a point class that you are referring to? Or must I create a new class like this? // Create a new class var point = new Point{ var myLatitude; var myLongitude; }; Please forgive me for such many questions, I am new on Esri and GIS, I am trying to get as much knowledge as I can.

‎04-20-2020

Hi Robert, Thank you very much for the response. I went through the article, but it is not clear on how to use getLatitude() and getLongitude() methods. Must I do it like this? var point = new Point( { getLatitude(); getLongitude(); });
