Attribute Inspector for Points editing

BrandonIves — Tue, 22 Apr 2014 16:38:03 GMT

I am attempting to get an application working where editors can click on a point feature and edit a form. I need the form to have a save button that when clicked will apply the edits to the feature.

I am selecting the point/s using an envelope. Is there a way I can tell what feature I need to apply the edits to on my save click event? I would like to store the edits to a feature as fields are changed and then only save the edits to the feature class with the save button.

I am trying to use this example to understand the edit saving and then the feature save. Attribute Inspector

Here is what I am working with right now. I am grabbing the point features within an envelope:

function initEditor() {
          var featureLayer = layersFS[1].layer;            

      var selectQuery = new Query();
      map.on("click", function (evt) {

          var centerPoint = new esri.geometry.Point
           (evt.mapPoint.x, evt.mapPoint.y, evt.mapPoint.spatialReference);
          var mapWidth = map.extent.getWidth();

          //Divide width in map units by width in pixels
          var pixelWidth = mapWidth / map.width;

          //Calculate a 10 pixel envelope width (5 pixel tolerance on each side)
          var tolerance = 10 * pixelWidth;

          //build query filter
          query = new esri.tasks.Query();
          query.returnGeometry = true;
          query.outFields = ["*"];

          //Build tolerance envelope and set it as the query geometry
          var queryExtent = new esri.geometry.Extent
                  (1, 1, tolerance, tolerance, evt.mapPoint.spatialReference);
          query.geometry = queryExtent.centerAt(centerPoint);
          featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (features) {
              if (features.length > 0) {
                  //store the current feature
                  for (var i = 0; i < features.length; i++) {
                      updateFeatures.push(features);                          
                  }
                  //map.infoWindow.setTitle(features[0].getLayer().name);
                  map.infoWindow.show(evt.screenPoint, map.getInfoWindowAnchor(evt.screenPoint));
              } else {
                  map.infoWindow.hide();
              }
          });
      });

Then I am planning to update the specific feature with the save button:

saveButton.on("click", function () {
          //need to figure out how to get the current feature with the save click, 
          //the envelope may return 1 to many records and I need the current feature
          updateFeatures.forEach(function(entry) {
          updateFeature.getLayer().applyEdits(null, [updateFeature], null);            
          }
       )});

      ///////Need to apply similar logic as save button click but this will update the current feature in the updateFeatures[]
      attInspector.on("attribute-change", function (evt) {
          //store the updates to apply when the save button is clicked 
          updateFeature.attributes[evt.fieldName] = evt.fieldValue;
      });

What is the best way to determine what my current feature is in the info window that is being edited?

Thanks for any advice!

We're trying to do the same thing. Were you ever able to figure out how to get this working completely?

Thanks.

Jennifer,

would this work? Using the attribute inspector | ArcGIS API for JavaScript‌

I'm trying to use the Attribute Inspector with Lines and Points. I was able to use that example to query polygons, but have so far been unsuccessful in querying lines and points for the attribute inspector.

Shouldn't the process be the same with every type of feature?

function findWells(evt) {

var selectionQuery = new esri.tasks.Query();

var tol = map.extent.getWidth()/map.width * 5;

var x = evt.mapPoint.x;

var y = evt.mapPoint.y;

var queryExtent = new esri.geometry.Extent(x-tol,y-tol,x+tol,y+tol,evt.mapPoint.spatialReference);

selectionQuery.geometry = queryExtent;

wellFeatureLayer.selectFeatures(selectionQuery,esri.layers.FeatureLayer.SELECTION_NEW);

};

This is what I use to pull points and lines.

Thanks, William. That helped.

This Multiple Attribute Inspectors | ArcGIS API for JavaScript‌ also helped with figuring out how to get the AI to handle the different layers.
