Question

你好吗？我在IONIC实施评级，尽管这基本上是有角度的。我想获得每个类别的价值。如果我符合规格，那就是动物＆＃34;我想得到我选择的价值。如果我有资格＆＃34;汽车＆＃34;我想获得我选择的价值。

我的问题是我总是为两个类别获得相同的值。我能做什么？。我想知道什么是最好的解决方案，因为我认为创建动态代码并且不想在n个类别中重复代码。

};

$scope.ratingsCallback = function(rating) {
 $scope.cars=rating;
 $scope.animals=rating;
 console.log('Selected rating is : ', rating);

 //is the same value :(
 console.log("animals: "+$scope.animals);
 console.log("cars: "+$scope.cars);
};

我建议使用其他离子评级库，例如this one，可以使用ng-model。因此，您可以将ng-repeat与数组一起用作模型，然后将<rating>指令绑定到用户设置评级时自动更新的属性。

以下是适合使用该lib并使其动态化的示例：

＆＃13;

angular.module('ionicApp', ['ionic', 'ionic.rating'])

.controller('MyCtrl', function($scope) {
  $scope.myTitle = 'IONIC RATINGS DEMO';

  $scope.categories = [{
    name: "animals",
    question: "What do you think about the animals?",
    rating: 0
  }, {
    name: "cars",
    question: "What do you think about the cars?",
    rating: 0
  }, {
    name: "flowers",
    question: "What do you think about the flowers?",
    rating: 0
  }];

  $scope.rating = {};
  $scope.rating.max = 5;

});

        {{category.question}}
        <rating ng-model="category.rating" max="rating.max"></rating>
      </div>
    </div>

    <pre>categories = {{categories|json}}</pre>
  </ion-view>
</body>
