Create Polygon Feature: Java Script

Vakhtang_Zubiashvili · ‎01-09-2020

Hi guys,

I am trying to use ArcGIS API for JavaScript Sandbox this sample to add polygon feature, i also use codes taking from here https://community.esri.com/thread/224031-how-to-create-a-polygon-js-api-49?commentID=811443&et=watch... from Robert Scheitlin, GISP, but can not combine this two sample to add polygon and update attributes.

Thank you for your help

Here is a code samples i use (you can see them in links too):

// ***********************************************************
      // Call FeatureLayer.applyEdits() with specified params.
      // ***********************************************************
      function applyEdits(params) {
        featureLayer.applyEdits(params).then(function(editsResult) {
          // Get the objectId of the newly added feature.
          // Call selectFeature function to highlight the new feature.
          if (editsResult.addFeatureResults.length > 0) {
            const objectId = editsResult.addFeatureResults[0].objectId;
            //selectFeature(objectId);
          }
        })

// called when sketchViewModel's create-complete event is fired.
        function addGraphic(event) {
          // Create a new graphic and set its geometry to
          // `create-complete` event geometry.
          const graphic = new Graphic({
            geometry: event.geometry,
            symbol: sketchViewModel.graphic.symbol,
            attributes: {}
          });

Based on the TIOBE Index for June 2016 Java is now more well-known than a variety of widely-used programming languages, including C++, Python, C#, PHP and JavaScript. The statistics on usage posted on various websites illustrate the immense popularity and importance of Java in the present day world. Java is an all-purpose programming language. Certain developers prefer to use Java to build desktop GUI applications as well as other developers create numerous web-based applications using Java technologies. In addition, Java is also used extensively for the development of mobile applications and games for Android which is the mobile platform with the biggest user base. There are plenty of reasons that Java is going to be a major factor over an extended period of time.
