WAB feature actions code ???

CharlesBailey — Tue, 02 Jan 2018 19:41:48 GMT

Where does the feature actions code go in the select widget manifest? What's wrong with this? Can someone please show me a correct sample? Thanks, cob

{
"name": "Select2",
"platform": "HTML",
"version": "2.6",
"wabVersion": "2.6",
"author": "Esri R&D Center Beijing",
"description": "",
"copyright": "",
"license": "http://www.apache.org/licenses/LICENSE-2.0",
"properties": {
"supportMultiInstance": false,

"featureActions": [{
"name": "ShowVertex",
"uri": "ShowVertexFeatureAction"
}]
}

}

Cob,

It does not go inside the properties object like you have it now:

{
  "name": "Select2",
  "platform": "HTML",
  "version": "2.6",
  "wabVersion": "2.6",
  "author": "Esri R&D Center Beijing",
  "description": "",
  "copyright": "",
  "license": "http://www.apache.org/licenses/LICENSE-2.0",
  "properties": {
    "supportMultiInstance": false
  },
  "featureActions": [{
    "name": "ShowVertex",
    "uri": "ShowVertexFeatureAction"
  }]
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It still won't work Robert - either it has no effect or the widget won't load. WHat I'm really trying to do is a calc geometry feature action on selected features, but I can't get past the first step for it to even show up in the dropdown. It worked in the demo as far as the sample widget but when I try to add it to the stemapp it won't load either.Here's the calculation feature action I'm trying to use - but as I said can't even get the first step...Thanks Robert - cob

Cob,

It is not going to show in the action menu if you are adding this to the manifest:

  "featureActions": [{
    "name": "ShowVertex",
    "uri": "ShowVertexFeatureAction"
  }]‍‍‍‍

It should be:

  "featureActions": [{
    "name": "CalculateGeometry",
    "uri": "CalculateGeometryAction"
  }]‍‍‍‍

Assuming you have the CalculateGeometryAction.js file in the select widget folder.

Re: WAB feature actions code ???

CharlesBailey — Tue, 02 Jan 2018 21:21:46 GMT

Right. If I wanted both would I have to have the 'featureActions' function twice? i.e.

"featureActions": [{
"name": "ShowVertex",
"uri": "ShowVertexFeatureAction"
}],

"featureActions": [{
"name": "CalculateGeometry",
"uri": "CalculateGeometryAction"
}]

OR,

"featureActions": [{
"name": "ShowVertex",
"uri": "ShowVertexFeatureAction",

"name": "CalculateGeometry",
"uri": "CalculateGeometryAction"
}]

?? But none of this is working - it shows nothing or won't load something with the manifest I think. Thanks, cob

RobertScheitlin__GISP — Sun, 12 Dec 2021 10:17:40 GMT

Cob,

Yep, neither is correct.

"featureActions": [{
  "name": "ShowVertex",
  "uri": "ShowVertexFeatureAction"
}, {
  "name": "CalculateGeometry",
  "uri": "CalculateGeometryAction"
}] ‍‍‍‍‍‍‍

It is suppose to be an array of objects as above.

It just doesn't show up - the vertex count does, but not the calc meas and it's in the manifest and strings. .

What does the browser console say?

Re: WAB feature actions code ???

CharlesBailey — Wed, 03 Jan 2018 16:36:07 GMT

?something about not being a constructor. here is a screen shot. Thanks Robert - cob

Re: WAB feature actions code ???

RobertScheitlin__GISP — Wed, 03 Jan 2018 16:48:55 GMT

Cob,

The error that says unexpected token is the real culprit. you should look at that line of code in the file indicated to find your code error.

Re: WAB feature actions code ???

CharlesBailey — Wed, 03 Jan 2018 19:01:56 GMT

?OK, finally got that error to disappear - back to the 'not a constructor error'- Here's the edited code too. Thanks-cob

Charles,

Your onExecute is not a function in your code the way you have your code setup... all those requires you have there need to be combined with the initial require array list and your onExecute need to be an actual function.

Re: WAB feature actions code ???

RobertScheitlin__GISP — Sun, 12 Dec 2021 10:17:42 GMT

Cob,

This is what I would expect the code to look like:

 define([
   'dojo/_base/declare',
   'jimu/BaseFeatureAction',
   'jimu/WidgetManager',
   "dojo/dom",
   "dojo/_base/lang",
   "dojo/json",
   "esri/tasks/GeometryService",
   "esri/tasks/AreasAndLengthsParameters"
 ], function(declare, BaseFeatureAction, WidgetManager, dom, lang, json, GeometryService, AreasAndLengthsParameters) {
   var clazz = declare(BaseFeatureAction, {

     iconFormat: 'png',

     isFeatureSupported: function(featureSet) {
       return featureSet.features.length > 0 && featureSet.features[0].geometry.type !== 'point';
     },

     onExecute: function(featureSet){
       var geometry = featureSet.features[0].geometry;
       var geometryService = new GeometryService("http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");
       geometryService.on("areas-and-lengths-complete", lang.hitch(this, function(evtObj){
         var result = evtObj.result;
         console.log(json.stringify(result));
         dom.byId("area").innerHTML = result.areas[0].toFixed(3) + " acres";
         dom.byId("length").innerHTML = result.lengths[0].toFixed(3) + " feet";
       }));

       //setup the parameters for the areas and lengths operation
       var areasAndLengthParams = new AreasAndLengthsParameters();
       areasAndLengthParams.lengthUnit = GeometryService.UNIT_FOOT;
       areasAndLengthParams.areaUnit = GeometryService.UNIT_ACRES;
       geometryService.simplify([geometry], lang.hitch(this, function(simplifiedGeometries) {
         areasAndLengthParams.polygons = simplifiedGeometries;
         geometryService.areasAndLengths(areasAndLengthParams);
       }));
     }
   });
   return clazz;
 });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I am not convinced that you will get access to your area and length dom objects the way you are doing it though.

Re: WAB feature actions code ???

Just changed computers and had to start over(again) – it doesn’t seem to like the simplify method in line 33…but when I comment out that part of the line is says unexpected token in line 36 (with the })):)). If I do anything to that line the whole thing blows up and won’t show my feature action in the ellipse dropdown (which has happened like a thousand times).

I had a ? about the DOM but need to get the code working first. Thanks Robert - cob

Re: WAB feature actions code ???

RobertScheitlin__GISP — Mon, 08 Jan 2018 21:18:32 GMT

Charles,

OK, then change this line:

var geometry = featureSet.features[0].geometry;

Re: WAB feature actions code ???

CharlesBailey — Mon, 08 Jan 2018 21:46:10 GMT

Now it has the Access-Control-Allow-Origin error – I’ve seen this before but have never been able to fix it – is it something in the index.html? Thanks, cob

Re: WAB feature actions code ???

RobertScheitlin__GISP — Mon, 08 Jan 2018 22:10:01 GMT

cob,

try replacing the GeomertyService url with your own GeometryService url then.

Re: WAB feature actions code ???

CharlesBailey — Mon, 08 Jan 2018 22:18:34 GMT

You mean, like the one on our arcgis server?

Re: WAB feature actions code ???

RobertScheitlin__GISP — Mon, 08 Jan 2018 22:24:17 GMT

yep

Re: WAB feature actions code ???

CharlesBailey — Mon, 08 Jan 2018 22:37:46 GMT

Ok that sort of works, but has to be on the network and most of our users are just in AGOL via internet. Is there any way to do it using the esri public service?
