Question

我之前也问过这个问题。也许有人可以在这里发现错误。

.controller('DishDetailController', ['$scope', function($scope) {
    var dish={
        name:'Uthapizza',
        image: 'images/uthapizza.png',
        category: 'mains', 
        label:'Hot',
        price:'4.99',
        description:'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',

                author:"John Lemon",
                date:"2012-10-16T17:57:28.556094Z"
            },
            {
                rating:2,
                comment:"It's your birthday, we're gonna party!",
                author:"25 Cent",
                date:"2011-12-02T17:57:28.556094Z"
            }
        ]
    };
    $scope.dish = dish;
}])
.controller('DishCommentController', ['$scope', function($scope) {
    $scope.newcomment = {
        rating : "",
        comment: "",
        author: "",
        date: new Date().toISOString()
    };
    $scope.submitComment = function () {
        $scope.newcomment.date = new Date().toISOString();
        $scope.newcomment.rating = parseInt($scope.newcomment.rating)
        console.log($scope.newcomment.comment);
        console.log($scope.newcomment.author);
        console.log($scope.newcomment.rating);
        console.log($scope.newcomment.date);
        $scope.dish.comments.push($scope.newcomment);
    }
}]);

在html部分我只有两三个文本框。按钮onclick中的SubmitComment。 Console.log向我显示我需要的结果。但我无法将其推向阵列。练习是教程的一部分。因此需要在单独的控制器中编写它们，这是由教程

碟形物体没有在第二个控制器中定义，它可以从错误中得到理解＆＃34; undefined＆＃34;。你必须找到一种方法从第一个控制器传递碟形物体＆＃34; DishDetailController＆＃34;到第二个＆＃34; DishCommentController＆＃34;。有几种方法可以做到这一点，一种方法是从第一个控制器将对象存入服务，然后从第二个控制器中的相同服务中检索它。据我所知，在控制器之间共享对象的最佳方式是通过服务。
