I'm new to AngularJS and trying to setup an app that reads an RSS feed and displays the items upon page load.
I have figured out how to have the data loaded and displayed upon clicking a link (see fiddle), but can't figure out how to have this happen on page load.
My thought is that I'm not using $scope properly or should be using a model.
Any help is appreciated.
Just call the method $scope.loadFeeds() after defining the method itself.
loadFeeds method would be defined, but obviously it wasn't.you have not called your controller function. just use this code for controller:
var app = angular.module('newsFeed', []);
app.controller('FeedController', ['$scope', 'FeedService', function ($scope, Feed) {
console.log('FeedController called.');
//These calls cause errors:
//$scope.loadFeeds();
//loadFeeds();
//this.loadFeeds();
//loadFeeds();
$scope.loadFeeds = function () {
console.log('loadFeeds called.');
Feed.parseFeed('http://www.rotoworld.com/rss/feed.aspx?sport=nfl&ftype=article&count=12&format=atom').then(function (res) {
$scope.rotoWorld = res.data.responseData.feed.entries;
});
};
$scope.loadFeeds();//you have leave this line pf code
}]);
Use ng-init directive that will call exactly after controller gets loaded & make much more impact while testing a code using Karma & Jasmine.
Markup
<div ng-controller="FeedController" ng-init="loadFeeds()">
..other html here
<div>
Though the better way would be calling loadFeeds method from controller at the end to ensure all the variables & methods have been initialized. You have to mock all the ajax response as mock data.
