Question

我遇到了使用以下结构从json文件中检索数据的麻烦。在我的controller.js文件中，我有：

var controllers = angular.module('hotels.controllers', []);

controllers.controller('AppCtrl', function ($scope, $http){

   $scope.list;

   $http.get('json-folder/name.json').success(function(data, status, headers, config) {

    $scope.list = data.data;
    console.log(data);


});

在那个name.json文件中，我有以下结构：

{
   "hotel": [
     {
       "id": 1,
        "name": "Some hotel name",
        "address": "123 Street",
        "category" : [{
            "id": 1,
            "name" : "Category 1",
            "bnb" : "yes",
            "simple" : "some value",
            "double" : "another value"
         },
         {
            "id": 2,
            "name" : "Category 2",
            "bnb" : "no",
            "simple" : "some value 2",
            "double" : "another value 2"
         },
        {
            "id": 3,
            "name" : "Category 3",
            "bnb" : "no",
            "simple" : "some value 3",
            "double" : "another value 3"
         }
         ]
      },
      {
        "id": 2,
        "name": "Some hotel name 2",
        "address": "33333 Street",
        "category" : [{
             "id": 1,
             "name" : "Category 1",
             "bnb" : "yes",
             "simple" : "some value",
             "double" : "another value"
         },
         {
            "id": 2,
            "name" : "Category 2",
            "bnb" : "no",
            "simple" : "some value 2",
            "double" : "another value 2"
         },
         {
            "id": 3,
            "name" : "Category 3",
            "bnb" : "no",
            "simple" : "some value 3",
            "double" : "another value 3"
         }
        ]  
        }
    ],
    "motel": [
        {
          "id": 1,
          "name": "Some motel name",
          "address": "321 Street",
          "category" : [{
              "id" : 1,
              "name" : "Category Motel 1",
              "bnb" : "yes",
              "simple" : "some motel value",
              "double" : "another motel value"
           },
           {
             "id" : 2,
             "name" : "Category Motel 2",
             "bnb" : "no",
             "simple" : "some motel value 2",
             "double" : "another motel value 2"
           }
           ]
       }
     ]
}

最后是我的html结构：

<div ng-controller="AppCtrl">
    <ul class="pull-left">
        <li class="pull-left" ng-repeat="hotel in list.hotels">
            {{hotel.name}}
        </li>
    </ul>
</div>
<div ng-controller="CatCtrl">
      <ul class="pull-right">
          <li class="pull-right" ng-repeat="cat in list.categories">
              {{cat.name}}
          </li>
      </ul>
  </div>

我没有得到任何回报，我没有任何错误...... 我想要的是一个带有酒店名称的ul li和另一个类似的div我希望再次列出类别名称以及酒店类别下的其他数据。请注意，CatCtrl与AppCtrl相同......

知道第一个我做错了什么，我应该在其他控制器中改变什么才能得到我需要的东西？

谢谢。

现在您已经掌握了第一部分，获取类别应该要求将代码更改为：

<div ng-controller="AppCtrl">
    <ul class="pull-left">
        <li class="pull-left" ng-repeat="hotel in list.hotel">
            {{hotel.name}}
            <ul class="pull-right">
                <li class="pull-right" ng-repeat="cat in hotel.category">
                    {{cat.name}}
                </li>
            </ul>
        </li>
    </ul>
</div>

我会依靠你的CSS技巧来正确安排显示。
