javascript变量在函数中赋值

Question

我有一个我想要分配的变量的问题，这是我的部分代码：

angular.module('my.controllers')
.controller('ReferralCtrl', function($scope, $rootScope, $window, $state, $q, $timeout, referralCasesGroupByCaseStatus, AuthenticationService, $ionicLoading) {

$scope.detailsPresent = {myVar: false};

$scope.showCaseStatusFromDashboard = function(number) { 
    $timeout(function() {
      $scope.$applyAsync(function() {
        $rootScope.fromDashboard = true; 
      })
    }, 1000, true);
      $scope.showCaseStatus(number); 
  }

 $scope.showCaseStatus = function(number) {

    if(changedNumber !== 0 && changedNumber !== number) {
      changedNumber = number;
    }
    else {
      if(changedNumber > 0) {
        $scope.$applyAsync($scope.detailsPresent.myVar = true);
      }
    }

    $timeout(function() {
      $scope.$applyAsync(function() {  
        referralCasesGroupByCaseStatus.showCaseStatus(number, $rootScope.listingDetails).then(function(listingCaseStatus) {
          $rootScope.listingByCaseStatus = angular.copy(listingCaseStatus);

          if(listingCaseStatus == 0 || listingCaseStatus == undefined || listingCaseStatus == null) {

            $scope.detailsPresent.myVar = true;  
            $scope.changeNumber = true; 
            $state.go('app.case_status') 
          }  
          else {
            $scope.detailsPresent.myVar = false;
            $scope.noMoreItemsAvailable = false; 
            $scope.changeNumber = true; 
            $state.go('app.case_status') 
          } 
        })
      })
    }, 1000);
  }

...

如果我取消注释'alert（result1）;'结果显示但 result1 中的文字未分配给事件。我怎么分配它？ 等待解决方案，谢谢。
