我在一个应用程序上工作，我想推入一个数组中的数据，但它不工作。 也许你可以看看我的代码。

错误消息时抛出： ionic.bundle.js：25642类型错误：无法读取属性 '标题' 未定义 的范围在$ scope.createEx（app.js：63）。 在范围$ scope.createEx （app.js：62）

     <ion-content padding="true" ng-controller="OverallCtrl">

      Create Exercise 
      </button> 

     </ion-content>

    </script> 

App.js

app.controller('OverallCtrl', function($scope, $ionicListDelegate, $state) { 

    $scope.selOption == "Chest"; 

    $scope.createEx = function(exer) { 
    if($scope.selOption == "Chest"){ 
     $scope.chestEx.push({title: exer.title, sets: exer.set, reps: exer.rep, exInf: exer.inf}); 
     console.log("Pushed to Chest Array."); 
     $state.go('chest') 
    }; 
    } 

    $scope.chestEx = [ 

      {title: "Crowls", sets: 3, reps: 15, exInf: "Make 5 minute pause between Sets."}, 

        ] 

})
