esriRequest calling a Asp.net Rest web service

JoseSanchez — Wed, 07 Dec 2016 15:55:39 GMT

Hello everyone,

I was able to call an asp.net vb.net Rest web service using this sample as template

https://developers.arcgis.com/javascript/3/jssamples/data_requestJson.html

and it works fine.

Now when I copy/paste the same code into the edit widget (Widget.js) code, it jumps from line:

var requestHandle = esriRequest

to line

this.editor.attributeInspector.refresh();

and it never executes this code: requestHandle.then(

I know that esriRequest is asynchronous, but I do not know how to change the code here to handle the return in the widget.

Here is the source code:

_worksAfterCreate: function (settings) {

...

this.editor.templatePicker.on("selection-change", lang.hitch(this, function () {

var selected = this.editor.templatePicker.getSelected();

if (selected) {

var featureLayer = selected.featureLayer;

on.once(featureLayer, "before-apply-edits", lang.hitch(this, function (evt) {

if (evt.adds && evt.adds.length > 0) {

// Query WasdIndex Layer for Atlas and TTRRSS

this.query = new Query();

var countOfFeatures = 0;

var polygon = evt.adds[0].geometry;

var centroid = polygon.getCentroid();

this.query.geometry = polygon;

this.query.returnGeometry = true;

this.query.outFields = ['*'];

this.query.spatialRelationship = Query.SPATIAL_REL_INTERSECTS;

this.queryTask.execute(this.query, function (results) {

// Populate ATLAS field

if (results.features && results.features.length > 0) {

dojo.forEach(results.features, function (feature) {

countOfFeatures++;

evt.adds[0].attributes.ATLAS = feature.attributes.ATLAS; }

)};

alert("Number of points in polygon " + countOfFeatures);

}, function (showErr) {

console.log('error in query execution');

});

// Populate Comment for testing purposes

if (evt.adds[0].attributes.hasOwnProperty('COMMENTS')) {

evt.adds[0].attributes.COMMENTS = 'TEST COMMENTS';

}

// Populate AASISID

if (evt.adds[0].attributes.hasOwnProperty('AASISID')) {

esriConfig.defaults.io.proxyUrl = "/proxy/";

var url = "http://localhost:59297/api/aasis";

var requestHandle = esriRequest({

"url": url,

"handleAs": "json",

"callbackParamName": "jsoncallback"

});

requestHandle.then( <<<<=== THIS IS WHERE I HAVE THE PROBLEM

function (response) {

console.log("Success: ", response);

function (error) {

console.log("Error: ", error.message);

});

}

this.editor.attributeInspector.refresh();

}

}));

}

}));

Jose,

So you are saying that you never get the console message that the web service was successful? Does your rest service not expect a input parameter?
