javascript - Angularjs 调用 $scope.$apply() 时出错

Question

调用 $digest 或 apply 时发生错误

  registerAjax = ->
    successRegister = ->
      $scope.showRegistrationPanel = false
      $scope.showEndRegistrationPanel = true
      $scope.$digest()
   errorRegister = (response) ->
      $scope.textErrorPanelRegistration = response.data.error
      $scope.showErrorPanel = true
      $scope.$apply()



   data =
     password: $scope.user.password
     firstName: $scope.user.firstName
    lastName: $scope.user.lastName
    email: $scope.user.email

   http.post REGISTER_URL, data
    .then successRegister, errorRegister

当调用 $digest 或 $apply 时，错误消失，但一切正常

Error: [$rootScope:inprog] http://errors.angularjs.org/1.4.7/$rootScope/inprog?p0=%24digest
at Error (native)

使用 Angular 的 $timeout service :

$timeout(function() {
  $scope.$apply();
});

这将在调用 $apply 之前自动等待当前摘要周期完成。
