解決Ionic的ion-slide-box 2條資料渲染問題

當slider資料清單是動态擷取時，如果資料結果隻有2條資料時，slider清單會多複制倆個，通過下面的slideChange方法做個判斷可以解決這個bug

starter

angular.module('starter')
 .directive('repeatDone', function () {
   return function (scope, element, attrs) {
     if (scope.$last) { // all are rendered
       scope.$eval(attrs.repeatDone);
     }
   }
})
           

html

<ion-slide-box auto-play="true" does-continue="true" slide-interval="3000" on-slide-changed="slideChanged($index)">
　　<ion-slide ng-repeat="pic in pics" repeat-done="repeatDone()"><img ng-src="{{pic}}" src="" alt="" width="" height="" /></ion-slide>
</ion-slide-box>
           

controller

app.controller('defaultCtrl', function($scope, $timeout, $ionicSlideBoxDelegate) {
    $scope.slideChanged = function(index) {  
        $scope.slideIndex = index;  
        if ( ($ionicSlideBoxDelegate.count() - ) == index ) {  
            $timeout(function(){  
                $ionicSlideBoxDelegate.slide();  
            },);  
        }  
    };
    $scope.getFiles = function() {
         Files.query({  
            //some parameters

         }).$promise.then(function(data) {
            $scope.week = data;
        });
    }

    $scope.repeatDone = function() {
      $ionicSlideBoxDelegate.update();
      //$ionicSlideBoxDelegate.slide($scope.week.length - 1, 1);
    };
　　
　　$http.get('api/get/slide_pics').success(function (response) {
　　　　$scope.pics = response.data;
　　});
});
