Scope-specific dynamic variable name

When attempting to create a dynamic variable name within an AngularJS foreach loop, I encountered the following issue:

angular.forEach($scope.posts, function (item) {
    // counter increment
    counter++;

    var idPage = 'feed' + counter;

    FeedService.parseFeed(url).then(function(res) {
        $scope.window[idPage] = res.data.responseData.feed.entries;
    });

});

Unfortunately, this code is not functioning as expected and triggers the error message: 

Cannot set property 'feed1' of undefined

Could someone please provide guidance on the correct syntax for achieving this task?

Answer №1

Is there a window property in your $scope object? If so, follow Maxim's solution. Otherwise, give this a try:

angular.forEach($scope.posts, function (item) {
    // increment counter
    counter++;

    var idPage = 'feed' + counter;

    FeedService.parseFeed(url).then(function(res) {
        $scope[idPage] = res.data.responseData.feed.entries;
    });

});
