Hi Robert, I have changed the creationMode to "continuous", but I still can not drop multiple pins. I can drop the first pin, when I drop the second one, the previous one disappears. Kind Regards Siyabonga Kubeka

Hi All I am using JavaScript and Esri maps.

Hi Robert, Thank you very much. I have used the following way and it worked: var zLatitude = window.parent.Xrm.Page.getAttribute("dea_latitude").getValue(); var zLongitude = window.parent.Xrm.Page.getAttribute("dea_longitude").getValue(); var latitudes = zLatitude.split(','); var longitudes = zLongitude.split(','); var myArrayLat = []; var myArrayLon = []; var coordinates = []; //Getting the latitudes debugger; for(i = 0; i < latitudes.length; i++) { myArrayLat.push(latitudes); } //Converting to clean latitudes var x = 0; var xlen = myArrayLat.length; while(x < xlen){ myArrayLat = parseFloat(myArrayLat ); x++ } //Getting the longitudes for(j = 0; j < longitudes.length; j++) { myArrayLon.push(longitudes ); } //Converting to clean longitudes var y = 0; var ylen = myArrayLon.length; while(y < ylen){ myArrayLon = parseFloat(myArrayLon ); y++ } console.log(myArrayLat); console.log(myArrayLon); for (var i=0; i<myArrayLon.length && i< myArrayLat.length; i++) { coordinates = [myArrayLon, myArrayLat]; } console.log(coordinates); var zoomed =[]; zoomed = coordinates[0]; var zoomed1 = zoomed[0]; var zoomed2 = zoomed[1]; console.log(zoomed1); console.log(zoomed2); Then I did the following: function addGraphics() { debugger; const vertices = [coordinates]; const polygon = createGeometry(vertices); validSymbol = createSymbol([0, 170, 255, 0.8], "solid", 2, [ 255, 121, 5 ]); newDevelopmentGraphic = new Graphic({ geometry: webMercatorUtils.geographicToWebMercator(polygon), symbol: validSymbol, attributes: { newDevelopment: "new store" } }); graphicsLayer.add(newDevelopmentGraphic); }

Hi All, I have an array that contains coordinates, I want to use those coordinates to draw a polygon, how can I do that? var myArr = [3364047.4454315286,-3228904.4514530962, 3364900.9929277417,-3228484.0477610803, 3365799.1274269233,-3229152.871795023, 3365206.741040882,-3229535.056936448, 3364047.4454315286,-3228904.4514530962]; I want to manipulate the contents of the above array to be something like this so that I can be able to draw the polygon: const vertices = [ [3364047.4454315286, -3228904.4514530962], [3364900.9929277417, -3228484.0477610803], [3365799.1274269233, -3229152.871795023], [3365206.741040882,-3229535.056936448], [3364047.4454315286,-3228904.4514530962] ]; I am using JavaScript, I want to draw a polygon on an Esri map.

Hi Robert, Can you please how me with an example that is working? I have changed my loops as above, now I get this error. Kind Regards Siyabonga Kubeka

‎07-05-2020

Hi Robert, I did use this way but I still get the error that says getLatitude() is not a function.

‎07-04-2020

Hi All, I need help with separation the latitude and longitude. I am drawing a polygon and getting the coordinates of each vertex of the polygon. This is what I have done to separate the coordinates but it is not working: 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 .getLatitude()); crmLongitude = String(gra.geometry.rings .getLongitude()); var LatLon = String(gra.geometry.rings ); console.log(LatLon); latlon = LatLon; } The error that I get when I debug I get an error that states that getLatitude() is not a function. Please assist. Kind Regards Siyabonga Kubeka
