/**

//Defining function for getUserProfile in service 
$scope.getUserCategory = function () {
    var data = {
        userTypeKeyId: Number(AUTH.userTypeKeyId),
        fieldKeyId: Number(AUTH.defaultFieldKeyId)
    };
    IntermediaryDashboardService.getIntCategory(function (response) {
        if (response != null) {
            if (response.data.isSuccess) {
                $scope.userCategories = response.data.userCategories;
            }
        }
    }, data);
};

  this.getIntCategory = function (callback, data) {
   var url = '/api/userCategories/filter/list/each';
   $http({
      method: 'POST',
      url: url,
      headers: {'Content-Type': 'application/x-www-form-urlencoded'},
      transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
      return str.join("&");
      },
      data
    }).then(
      function (response) {
        //Success Function
        callback(response);
      },
      function (response) {
        //Failure function
        callback(null);
    }
   }

<ul ng-repeat="category in userCategories" class="ng-cloak">
  <li style=" padding-top: 11px;">
    <a href="#" ng-click="getAlbumInIntermediary(category.categoryKeyId)">
      {{category.categoriesDto.categoryName}}
    </a>
  </li>
</ul>

Answer 1

简单使用

ng-if="intermediaryAlbumCount.length"

因为0被视为假。

但数据不会显示在HTML页面中

不要将回调与Promises混合。

您在服务中执行异步调用并解析原始Promise。因此，创建新的Promise并将其解析为控制器：

 this.getIntCategory = function (callback, data) {

   var deferred = $q.defer(); 
   var url = '/api/userCategories/filter/list/each';
   $http({
      method: 'POST',
      url: url,
      headers: {'Content-Type': 'application/x-www-form-urlencoded'},
      transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
      return str.join("&");
      },
      data
    }).then(function (response) {
       deferred.resolve(response.data);
      },
      function (response) {
        deferred.resolve({});
    });
     return deferred.promise;
   }

现在在控制器中你可以写成：

 $scope.getUserCategory = function () {           
    IntermediaryDashboardService.getIntCategory().then(function (result) {
          $scope.userCategories = response.data.userCategories;                           
    }, function (result) {
        alert("Error: No data returned");
     });    
  }
