javascript - 如何将json数据项转换为变量？

Question

我正在处理来自电视 API 的 Json 数据。从这个 API 我想使用“tvshow.episode. ratings.loved”值。我如何将该值链接到类似的东西$scope.like = tvshow.episode. ratings.loved;我想用这个做一些数学运算。我如何将这个冗长的 json 文本转换为 $scope.like？我应该将它包含在我的代码中的哪里？请帮忙

var app = angular.module('MyApp',[]);

app.controller("mainController", function ($scope, $http, $filter){

    $scope.filteredItems = [];       

    $scope.pagedItems = [];
    $scope.curPage = 1;

     $scope.init = function() {

        $http.jsonp('http://api.trakt.tv/calendar/premieres.json/' + $scope.apiKey + '/' + apiDate + '/' + 30 + '/?callback=JSON_CALLBACK').success(function(data) {

            angular.forEach(data, function(value, index){


                angular.forEach(value.episodes, function(tvshow, index){
                    tvshow.date = date; 
                    $scope.results.push(tvshow);
                    angular.forEach(tvshow.show.genres, function(genre, index){
                        //Only add to the availableGenres array if it doesn't already exist
                        var exists = false;
                        angular.forEach($scope.availableGenres, function(avGenre, index){
                            if (avGenre == genre) {
                                exists = true;
                            }
                        });

                    });

                });
            });                  
            };  


        }).error(function(error) {

        });
    };

    app.$inject = ($scope, $filter);



});

之后

$scope.groupedItems = [];

添加

$scope.loved = [];

并在此循环中添加

 angular.forEach(value.episodes, function(tvshow, index) {
      // .... code
    $scope.loved.push(tvshow.ratings.loved);
})

如果您只想显示每个项目的评分，则需要在模板中添加此内容

<span class="label"><i class="icon-thumbs-up"></i> {{tvshow.show.ratings.loved}}</span> 
<span class="label"><i class="icon-thumbs-down"></i> {{tvshow.show.ratings.hated}}</span> 

结果你得到了包含所有“喜欢的评级”的数组
