Question

我最近改变了我的工厂 FROM

app.factory('controllerComm', function($rootScope)
{
  var showVforum    = {};
  showVforum.result = false;
  showVforum.prepBroadcast = function(val)
  {
    this.result = val;
    this.broadcastVal();
  }

  showVforum.broadcastVal = function()
  {
    $rootScope.$broadcast('toggleVforum')
  }
  return showVforum;
});

THIS

app.factory('controllerComm', ['$rootScope', function($rootScope)
{
  var showVforum    = {};
  showVforum.result = false;
  showVforum.prepBroadcast = function(val)
  {
    this.result = val;
    this.broadcastVal();
  }

  showVforum.broadcastVal = function()
  {
    $rootScope.$broadcast('toggleVforum')
  }
  return showVforum;
}]);

我这样做是出于JS缩小的原因。在我改变它之前，我在我的一个控制器中工作了这个：

$scope.$on('toggleVforum', function()
{
  $scope.isVisible = controllerComm.result;
  $('#vforum').verticalAlign();
  player.play();
});

controllerComm.result现在正在返回undefined，因为我改变了工厂，我无法弄清楚原因。有什么想法吗？

修改

错误：

尝试使用广播传递结果变量。

$rootScope.$broadcast('toggleVForum',{result: this.result});

controllerComm未在 $ on 侦听器中定义，即使您可能将其注入到定义侦听器的控制器中。

$scope.$on('toggleVForum',function(evt,args){
    $scope.isVisible = args.result;
    ...
});
