javascript - 从 json 对象获取特定参数值

Question

我定义了工厂，如下所示

app.factory('Category', function($resource,$rootScope) {
  return $resource('api/category');
});

这是我的 Controller :

app.controller('ChartCtrl4', function ($scope, Category) {
   $scope.category = Category.get();
   $scope.totalCategory = ???      //total:2
});

从Category.get获取的数据:

{
 message: "Category Retrieved Successfully",
 data: {
  total: 2,
  per_page: 10,
  current_page: 1,
  last_page: 1,
  next_page_url: null,
  prev_page_url: null,
  from: 1,
  to: 1,
  data: [
   {
    ...
   },{
    ....
   }
 ]
}
}

我想在我的 Controller 中访问total的值，即2。

试试这个:

app.controller('ChartCtrl4', function ($scope, Category) {
   Category.get()
    .$promise.then(function(response) {
      $scope.totalCategory = response.data.total;
  });
});
