函數未定義在角

Question

嗨我不斷收到此錯誤。我試圖讓破碎的圖像圖標不出現在Angular Ionic應用程序中。我有這個功能，但它一直說anonImg沒有定義。我不知道如何定義這個？

function anonImg(image){ 
 
    image.src = 'https://instagramimages-a.akamaihd.net/profiles/anonymousUser.jpg'; 
 
    }

和我的HTML是

<ion-content class="climb-pics"> 
 
     <img ng-src="{{urlForImage(selected_.images)}}"/> 
 
     <img onerror="anonImg(this);" ng-src="{{urlForImage(selected_.imageTwo)}}"/> 
 
     <button type="button" class="button button-assertive" ng-click="closeModal(1)">Close</button> 
 
     <p>&nbsp;</p> 
 
    </ion-content>

我應該在一個函數或東西被包裝的功能？我只是不現在什麼時候我得到的錯誤做「的ReferenceError：anonImg沒有定義」

這裏是我的控制器代碼：

.controller('ClimbController', ['$scope', '$stateParams', 'Products', 'Climbs', '$ionicModal', '$localStorage', '$cordovaCamera', '$cordovaFile', 
    function($scope, $stateParams, Products, Climbs, $ionicModal, $localStorage, $cordovaCamera, $cordovaFile) { 

     $scope.product_id = $stateParams.productId; 
     console.log('ClimbController: ' + $scope.product_id); 
     // ClimbsController: 2 

     $scope.urlForImage = function(imagePath) { 
      console.log('imagePath: ' + imagePath); 
      return Products.urlForImage($scope.product_id, imagePath); 
     } 

     var filename = Products.getFilenameFromLocalStorage($scope.product_id); 
     console.log(filename); 

     var climbId = $stateParams.climbId; 
     var areaId = $stateParams.areaId; 

     if (!isNaN(climbId)) { 
      climbId = parseInt(climbId); 
     } 

     if (!isNaN(areaId)) { 
      areaId = parseInt(areaId); 
     } 

     $scope.selected_ = {}; 
     $scope.items = []; 
     $scope.details = true; 
     $scope.data = ''; 
     $scope.noteParams = { 
      text: null 
     }; 

     // looping though all data and get particular product 
     $scope.selectClimb = function(areas){ 
      areas.forEach(function(data) { 
       if(data._id == climbId){ 
        $scope.selected_ = data; 
       } 
      }); 
     } 

     // get all posts // try some function to get a single produt from server 
     $scope.getPosts = function(){ 
      Products.loadGuidebook(filename).then(function(data) { 
       // NOTE: data = the whole feed.json file 
       console.log(data); 

       // data = feed.json file 

       var climbs = []; 
       data.areas.map(function(area) { 
        if (area._id === areaId) { 
         climbs = area.climbs; 
        } 
       }); 
       $scope.selectClimb(climbs); 
      }, 
      function (error) { 
       console.log(error); 
      }); 
     } 

     // picture slider logic 
     $scope.allImages = $scope.images; 

     //hide div with broken images 
     anonImg = function(image){ 
      image.src = 'https://instagramimages-a.akamaihd.net/profiles/anonymousUser.jpg'; 
     } 

     $scope.load(); 
     $scope.getPosts(); 
    } 
])

您還沒有發佈的控制器代碼，你應該有在您的控制器和功能$範圍應界定爲，

$scope.anonImg = function(image){ 
    image.src = 'https://instagramimages-a.akamaihd.net/profiles/anonymousUser.jpg'; 
}
