Dynamic variable name of scope

Question

I try to define a dynamic variable name in a angularjs foreach, like this :

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;
    });

});

so, it's doesn't work and i have this error : Cannot set property 'feed1' of undefined

what's the correct syntax ?

Could you provide a plnkr?

$scope['feed1'] = 'test'; console.log($scope.feed1);

Does your $scope object have a window property? If yes, go with Maxim's answer. If not, try this:

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

    var idPage = 'feed' + counter;

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

});
