Question

我正在尝试将控制器范围变量设置为数据，但没有运气。控制器中的console.log显示未定义。感谢帮助！

我的角度服务有以下代码 -

<title>
  <c:choose>
    <c:when test="${requestScope['com.escenic.context']=='art'}">
      <c:out value="${article.title}" escapeXml="true"/> -
    </c:when>
    <c:when test="${section.uniqueName != 'homepage’}”>
      <c:out value="${section.name}" escapeXml="true"/> -
    </c:when>
  </c:choose>

  <c:choose>
    <c:when test=“${wesite.name eq ‘pg’}”>
    pg website name
    </c:when>
    <c:when test="${wesite.name eq ‘pk’}”>
    pk website name
    </c:when>
    <c:when test="${wesite.name eq ‘ls’}”>
    ls website name
    </c:when>
  </c:choose>
</title>

我在控制器中引用它如下 -

service('VyrtEventService', ['$http', function($http) {
  var events = [];

  this.getArtistEvents = function(artistId) {
    var url = '/api/users/' + artistId + '/';

    var promise = $http.get(url).success(function(data, status, headers, config) {
      events = data.artist.events;
      console.log(events);
      return events;
    }).catch(function(error) {
      status = 'Unable to load artist data: ' + error.message;
      console.log(status);
    });

    return promise;
  };
}]);

Answer 1

您应该在控制器中设置$scope.events = data，因为您的承诺在结算时已经返回data.artist.events

Answer 2

从控制器的任何位置将范围传递给服务。确保注入服务。

controllersModule.controller('MyCtrl', function($scope, $filter, $http, $compile, ngTableParams, **FactoryYouwant**) 
    {

        **FactoryYouwant**.getdata($scope.**scopeYoutwantTopass**).then (function(responseData){    
        var ResponseFromServer =responseData.data;
    }

in service

    controllersModule.factory('**FactoryYouwant**, function($http) {
        var responseData = null;

        return {
            getdata : function(**data**){     (you dont have to use $)                  
                responseData = $http.post or whatever actually gets you data;
                return responseData;
            }

          };
    });

我希望这可以帮助您在控制器的任何位置调用从服务获取数据。
