Issues with AngularJS controller retrieving data from AJAX calls

Currently utilizing Angular 1.4.7 in conjunction with angular-ui-router 0.2.15 as the state router. The standard controller setup I have is as follows:

var app = angular.module('App.Page1',[....]);
app.controller('Page1Ctrl',['$scope' ... ,function($scope ...) {
...
  $scope.records = [];

  // jsRoutes.controllers.Page1.list() - serves as ajax wrapper
  jsRoutes.controllers.Page1.listitems().ajax({
    success: function(data) { 
       console.log("RECV",data);
       $scope.records = data 
    },
    error: function(res){ console.log("ERROR",res); }
  });
});

The controller template simply displays the records as follows:

<h1>Page1</h1>
<div ng-repeat="record in records" class="row">
    {{record.name}} ...
</div>

Although it functions, there are occasional stability issues. There are times when only the header is displayed on the page. It appears that the parsers array is empty, even though the network requests show that the list request was received successfully and the success function ran. Upon refreshing the page, the data reappears.

Answer №1

Your asynchronous service call is not within the AngularJS framework, so you must explicitly notify Angular when data changes occur.

To achieve this, make sure to include $scope.$apply() in your success function after updating the $scope variable with the retrieved data.

$scope.parsers = data;
$scope.$apply();

Following these steps should resolve the issue you are experiencing.
