Consuming web service REST JSON with esriRequest

AlbertoLópez — Tue, 23 Aug 2016 12:26:38 GMT

Hello;

I want to create a widget with a function (function _invoqueWS) that retrieves data from a web service REST JSON with esriRequest.

This function must be invoked from other functions of the widget (startup función for example an others).

I created the following functions but when I try to return the JSON content variable, the variable in the startup function is undefined or null. I have also tried to initialize a global variable in the function _invoqueWS and recover the value in function startup , but without results. What am I doing wrong. In the invoqueWS function the JSON data is correct.

I am using API 3.17 javascript

Thank you very much, greetings.

startup: function()

_invoqueWS: function() {

var resultado

var url_servicio="XXXXX";

var layersRequest = esriRequest({

url: url_servicio,

handleAs: "json",

load: function (result)

{

resultado = result.ElementosEstacionOutput[0].ID_ESTADOS_INST_EXPRESION;

error: function (error)

{

resultado= error;

}

});

return resultado
