Service runs twice

[mark goldin]

Service:

var myModule = angular.module('motoAdsApp', []);

myModule.factory("AirportService", function ($http, $q) {

    return {

        getData : function(dateFrom, dateTo){

            var deferred = $q.defer();

            var response = $http({

                    method: "get",

                    crossDomain: true,

                    dataType:"xml",

                    contentType: "application/xml",

                    url: "http://localhost/SomePage?parameters

                });

            response.success(function (data) {

                deferred.resolve(data);

            });

            response.error(function (data) {

                alert('Error');

            });

            // Return the promise to the controller

            return deferred.promise;

        }

    }

});

Controller:

var motoAdsApp = angular.module("motoAdsApp");

motoAdsApp.controller('AirportControllers', function($scope, $http, AirportService) {

    var result = AirportService.getData('09/07/2014', '09/14/2014').then(function(data) {

var json = $.xml2json(data);

  $scope.airports = json.testData;

  });

.......

The server gets hit twice when I load the page. Any idea why?

Thanks

Is one of the two hits an OPTIONS request? If so, that's the CORS preflight.

In the Console it says:

XHR finished loading: GET ......

XHR finished loading: GET ......

Two identical lines.

I had problems like that when I attached the same controller to multiple viewports on the same page (using ui-router), so I'm not sure if that's the thing. Where'd you put the console.log command to output that info? Have you confirmed on the server side, or in the network tab of the debug tools that the $http service is getting hit twice for certain?

Try adding some $log.info() or console.log() statements in various places to see what is going on. Add log statements to the beginning of the controller to see if the controller gets created twice. Also add log statements to AirportService (above the return) and insideAirportReturn.getData function.

I think I found the problem. I had ng-controller specified multiple times in the same page as it was suggested. Moved it to the top, no more multiple hits.
